Re-Visiting T.S. Eliot’s Poetry through Henri Lefebvre’s Rhythmanalysis

This paper explores the elements of rhythm in the social space in T.S. Eliot’s early poems and The Waste Land. One of the leading literary figures of the modernist era, Eliot dealt with the representation of the alienated individual within the boundary of the upper-middle class which can be followed especially in “The Lovesong of J. Alfred Prufrock.” Regarding the theoretical context of the study, Henri Lefebvre’s rhythmanalysis theory is applied to reveal how Eliot observed, understood and listened to the rhythms of city life. While observing people within the culture of the city, Eliot listened to the mechanisms present in this space. However, his concern of space and sound did not follow a single route, yet led to a wide, universal level. Thus, this paper intends to display Eliot’s perception of rhythm in his poems from the perspective of Lefebvre’s rhythmanalysis.

Mechanical, stress corrosion cracking and crystallographic study on flat components processed by two combined severe plastic deformation techniques

Although the current field of application of Al–alloy 7075 (AA7075) is vast, it is still limited due to some drawbacks, especially due to its susceptibility to stress corrosion cracking (SCC). This work aims to evaluate the microstructural, mechanical, and stress corrosion cracking (SCC) behaviors on an AA7075 in flat format deformed by a combination of repetitive corrugation and straightening (RCS) and accumulative roll bonding (ARB) techniques. Four different deformation routes were applied, namely: ARB (A), RCS (R), RCS + ARB (RA) and ARB + RCS (AR). As expected, the efficiency for grain refinement depends on the applied route, in terms of average grain size regarding the initial condition IC): AR > A > RA > R. All conditions resulted in unimodal and widened grain size distributions of micro-, submicro- and nano-metric dimensions. The study of crystallographic orientations showed that route R did not generate any new texture, whereas different preferred orientations were obtained for routes A, RA, and AR. The hardness and three-point bending tests showed an improvement of mechanical strength in the following order: AR > RA > A > R. The cracks per cm2 obtained in the corrosion study indicated that the best SCC resistance was R > A > AR > RA. Based on the above, the best combination of microstructural, mechanical, and SCC properties until one deformation pass was obtained by the single route of the ARB process.

Optimal Planetary Surface Routing Considering Exploration Values and Synergies

This paper proposes a new routing problem that can handle the synergy of exploring multiple sites for planetary surface exploration planning. The new problem aims to maximize the sum of profits (e.g., scientific information) obtainable by visiting a subset of candidate sites with given resource constraints (e.g., time and fuel) while considering the synergy (both positive and negative) from visiting two or more related sites. A mathematical formulation for this new problem referred to as the vehicle routing problem with profits considering synergy is developed. A special formulation for the problem considering the synergy only within a single route, referred to as the vehicle routing problem with profits considering single-route synergy, is also investigated. Column-generation-based procedures to find near-optimal solutions and corresponding optimality gaps for these problems are presented. The effectiveness of the proposed problem formulations and solution procedures are demonstrated through numerical experiments.

Phytochemical characteristics and the study of acute toxicity of extracts from fruit Рrunus domestica

The increased demand for modern phytopreparations is dictated by their wide application in the complex treatment of various diseases, the presence of low toxicity and the pharmacoeconomic component. Phytochemical analysis of medicinal plants reveals not only potential therapeutic effects, but also assumes their toxicological properties. In this context, the Prunus domestica, widely spread on the territory of our country and well known for its medicinal properties and applications in folk medicine, has attracted our attention.
 The aim of the work was to investigate the phytochemical composition of extracts obtained from fruit Prunus domestica and to study their toxic properties.
 Phytochemical analysis of the extracts obtained from fruits Prunus domestica was carried out according to the original method of extracting biologically active compounds, using instrumental research methods using modern laboratory analytical equipment.
 Studies of the safety of four extracts from Prunus domestica (liquid EC-1, EC-2 and dry CEPC, CEV) with the calculation of median lethal doses were carried out on mice and rats with the single intragastric and intraperitoneal routes of administration according to the method of T. V. Pastushenko. The degree of toxicity was determined according to the classification of K. K. Sidorov.
 Phytochemical study of extracts from fruit Prunus domestica provided information on the presence in their chemical composition of flavonoids, the sum of phenolic compounds, anthocyanins, neutral sugars, amino acids, organic and hydroxycinnamic acids. A higher content of the sum of phenolic compounds in the aqueous (ЕС-1) and alcoholic extracts (ЕС-2) as well as the presence of neutral sugars as products of hydrolysis of homopolysaccharides (СEV extract) and heteropolysaccharides (CEPC extract).
 Experimental studies proved that EC-1, EC-2, CEPC and SEV extracts had low toxicity beyond 15 000 mg/kg when administered orally and 3 000 mg/kg when administered intraperitoneally. The LD50 of the studied extracts of mice and rats after intraperitoneal injection was determined, which was more than 3 000 mg/kg.
 The chemical composition of biologically active compounds of extracts from the fruit Prunus domestica, which provides promising directions for further study of their pharmacological properties, has been investigated.
 Analysis of experimental data on acute toxicity of the studied extracts showed that they belong to the IV class of toxicity “relatively harmless substances", according to K. K. Sidorov classification. The LD50 of extracts from the fruit Prunus domestica for oral administration could not be determined, and the LD50 of the studied extracts for mice and rats after intraperitoneal administration was more than 3 000 mg/kg.

Multi-mode readout via opto-mechano-photothermo-responsive luminescence from electron trapping material for optical information storage application

Optical storage material is one of the promising candidates for next generation of information memory medium owing to large capacity, reusable rewritable, and rapid response performance. However, as the typical optical storage medium, electron trapping materials (ETMs) are limited in applications of information preservation or optical display technology due to their single readout route relying on photostimulated luminescence (PSL). A crucial limitation to the feasibility of multi-mode optical information readout is the inevitable mismatch between trap depth and the energy of external stimuli. In this study, by introducing Bi3+ ions as intermediate levels between deep traps and emitters, we developed a LiTaO3:Tb3+/Bi3+ (LTO) material that can simultaneously response to optical, mechanical, and thermal stimuli efficiently, showing as multiple trap-controlling luminescence. The tantalate material was endowed with opto-mechano-responsive readout capacity when assembled with polymer matrix. Moreover, by utilizing LiCaYb0.5Nd0.5(WO4)3 microcrystals (LCYW) with near-infrared-induced photothermy property, we designed a LTO-LCYW bilayer composite film then achieved non-contact thermo-responsive readout of optical information via photothermo-stimulated luminescence. These findings provide a unique perspective for designing multi-mode responsive luminophors and photonic devices towards widespread applications, especially optical display, optical memory technology, and anticounterfeiting.

Persistent racial diversity in neighborhoods: what explains it and what are the long-term consequences?

ABSTRACT We explore neighborhoods in Southern California from 1980 to 2010 that exhibit persistent racial diversity (PRD) and the consequences of this PRD. Initial exploratory analyses show that the racial composition of the area surrounding the neighborhood in 1980 is associated with which neighborhoods become PRDs. Our primary analyses compare how PRD neighborhoods change over time (1980–2010) based on several socio-demographic measures to a matched group of non-PRD neighborhoods that had similar characteristics in 1980. The key finding is that PRD neighborhoods improved more on per capita income and percent in poverty compared to their matched tracts from 1980 to 2010. We also found that there was not a single route to persistent diversity, but rather a myriad of pathways through which racial/ethnic diversity can persist over a long time period at the neighborhood level.

Travel time prediction of urban public transportation based on detection of single routes.

Improving travel time prediction for public transit effectively enhances service reliability, optimizes travel structure, and alleviates traffic problems. Its greater time-variance and uncertainty make predictions for short travel times (≤35min) more subject to be influenced by random factors. It requires higher precision and is more complicated than long-term predictions. Effectively extracting and mining real-time, accurate, reliable, and low-cost multi-source data such as GPS, AFC, and IC can provide data support for travel time prediction. Kalman filter model has high accuracy in one-step prediction and can be used to calculate a large amount of data. This paper adopts the Kalman filter as a travel time prediction model for a single bus based on single-line detection: including the travel time prediction model of route (RTM) and the stop dwell time prediction model (DTM); the evaluation criteria and indexes of the models are given. The error analysis of the prediction results is carried out based on AVL data by case study. Results show that under the precondition of multi-source data, the public transportation prediction model can meet the accuracy requirement for travel time prediction and the prediction effect of the whole route is superior to that of the route segment between stops.

Evolution of a Short and Stereocontrolled Synthesis of (+)-7,20-Diisocyanoadociane.

A full account of the development of a concise and highly stereoselective synthesis of (+)-7,20-diisocyanoadociane (DICA)─a structurally complex isocyanoditerpene with potent antiplasmodial activity─is described. The strategy that evolved relies on the rapid construction of unsaturated tricyclic precursors designed to undergo stereocontrolled Birch reductions and a subsequent "bay ring" formation to generate the isocycloamphilectane core. This report is divided into three sections: (1) a description of the initial strategy and the results that focused our efforts on a single route to the DICA core, (2) a discussion of the precise choreography needed to enable a first-generation formal synthesis of (±)-DICA, and (3) the execution of a 13-step second-generation synthesis of (+)-DICA that builds on important lessons learned from the first-generation effort.

Starch films containing starch nanoparticles as produced in a single step green route

Thermoplastic starch films with glycerol and nanoparticles were prepared from regular cornstarch in a single and quick step using the green chemical principle. Starch nanoparticles (SNPs) were produced by nanoprecipitation with the addition of ethanol as nonsolvent to the hot and room temperature polymeric dispersion. Contact angle increased from 41°, for the control sample, to 67°, for the film produced with glycerol as a plasticizer and by adding alcohol to the hot polymeric dispersion, which indicated a significant decrease in hydrophilicity. SNPs acted as a reinforcing agent and the mechanical properties varied as a function of the presence of plasticizer. Films prepared without glycerol were more rigid presenting the highest Young’s modulus (E = 3640 ± 209 MPa) and the lowest elongation at break (εmax), whereas the films prepared with glycerol were more flexible with the lowest E value and higher εmax around 23%.

A single rapid route synthesis of magnetite/chitosan nanocomposite: Competitive study

At last decides, the modification of synthesis protocol towards shorter reaction time, fewer steps, and lower resources cost was needed. The synthesis of magnetite (Fe3O4) polymer nanocomposite is heavily studied nowadays due to its promising applications. In this study, magnetite chitosan nanocomposite was synthesized through two competitive routes; a new single route synthesis based on co-precipitation at hydrothermal conditions, and the second route a conventional multi-synthetic route based on using the blending solution method after magnetite nanoparticles synthesis by the co-precipitation method of magnetite. The synthesized Fe3O4 and its nanocomposites are characterized by several techniques, including Fourier transition infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibration sample magnetometer (VSM). The results showed magnetite polymer nanocomposite synthesized via a single synthetic route had less particle size, more distribution in the chitosan matrix, and higher magnetization saturation than that synthesized via a multi-synthetic route. Adsorption of Rodamine 6G dye on magnetite chitosan nanocomposite was studied in different parameters. The adsorption results showed a rapid process following the Tempkin isotherm.

Waiting time and headway modeling considering unreliability in transit service

• Waiting time models for feeder-trunk and demand responsive service are revisited. • New formulation is developed to estimate mean waiting time for unreliable services. • Waiting time of passengers at destination is overlooked in previous studies. • Most of the previous studies underestimate the mean waiting time of passengers. • Classic optimum headway formulations are updated using the proposed approach. Waiting cost is usually considered as the highest cost imposed to passengers in transit systems. Efficient planning and operations of transit systems require accurate estimation of passengers’ waiting time. While the assumption of half the headway, as the mean waiting time experienced by transit users, has been extensively used in waiting time cost estimation, it is not always a realistic assumption considering heterogeneous passengers, service irregularities, and different types of transit services. In addition, many transit studies considered the waiting times of passengers only at the origin, while waiting times can also be incurred at transfer points and the destination, the latter for passengers with fixed arrival time at their destination. In this paper, we developed new mean waiting time formulations for different transit systems, including feeder-trunk service, Dial-a-Ride service, and single route with unreliable service. All possible combinations of types of passenger (planning and non-planning, with fixed and flexible arrival time at destination) and service types (schedule-based/frequency-based and high-frequency/low-frequency) are considered to capture the underlying dynamics of transit systems. The developed approach in this paper could be utilised in transit studies to better model these underlying dynamics and to achieve better designs and more efficient operations.

Quality of Service in Mobile Adhoc Networks with Non-Saturation Conditions

Numerous research has been conducted in order to investigate the performance of IEEE 802.11LEACH for a single-cell Wireless Local Area Network (WLAN) under saturation conditions. Saturation conditions are those in which it is anticipated that the queues of nodes will never be empty. To put it another way, there is always a packet waiting to be sent out from each and every node in the network. The term infinite load refers to the condition of saturation, which is a situation that may be regarded as having an endless load. Even though conducting an analysis under saturated conditions may provide some insight into how well the network operates in a high-pressure setting, this strategy does not appear to be practical because there is a possibility that the network will not always be at capacity. Even though conducting such an analysis under saturation circumstances may provide some insight into how well the network operates in a high-pressure setting, it is still not practical. When using CQSR, the source is aware of the correlation that exists between the many different paths that go to the destination. When it comes to the provision of quality service in an ad hoc network, having several pathways among a specific cause and an endpoint may be of assistance in the following scenarios. Having multiple pathways between a source and a destination may also be of assistance when it comes to the provision of quality service. It is feasible that a single channel will not be able to deliver adequate resources to meet the desired quality of service if the resources of mobile nodes are limited. This scenario might occur if mobile nodes are subject to resource limitations. The requirements of the application in terms of the quality of service might, however, be satisfied by the resources located along any one of the many possible paths that could exist between the specified pair of nodes. It seems likely that this will turn out to be the situation. The task force may be dispersed over a number of different routes if there are adequate resources available along each route. To put it another way, data packets are sent along each path that satisfies the criteria for acceptable quality-of-service levels. If you use many routes instead of just one, you may be able to obtain a throughput that is far higher than you would with a single route. In the previous proposed work, we did an analysis of IEEE 802.11 LEACH for an ad hoc network under saturation conditions. Saturation circumstances refer to scenarios in which it is believed that the queues of nodes are never empty. On the other hand, it is likely that the nodes that make up an ad hoc network will not always be totally filled.

A systematic framework for urban smart transportation towards traffic management and parking

<abstract> <p>Considering the wide applications of big data in transportation, machine learning and mobile internet technology, artificial intelligence (AI) has largely empowered transportation systems. Many traditional transportation planning and management methods have been improved or replaced with smart transportation systems. Hence, considering the challenges posed by the rising demand for parking spaces, traffic flow and real-time operational management in urban areas, adopting artificial intelligence technologies is crucial. This study aimed to establish a systematic framework for representative transportation scenarios and design practical application schemes. This study begins by reviewing the development history of smart parking systems, roads and transportation management systems. Then, examples of their typical application scenarios are presented. Second, we identified several traffic problems and proposed solutions in terms of a single parking station, routes and traffic networks for an entire area based on a case study of a smart transportation systematic framework in the Xizhang District of Wuxi City. Then, we proposed a smart transportation system based on smart parking, roads and transportation management in urban areas. Finally, by analyzing these application scenarios, we analyzed and predicted the development directions of smart transportation in the fields of smart parking, roads and transportation management systems.</p> </abstract>

Novel Ta/chitosan-doped CuO nanorods for catalytic purification of industrial wastewater and antimicrobial applications.

Novel tantalum (Ta) and chitosan (CS)-doped CuO nanorods (NRs) were synthesized using a single step co-precipitation route. Different concentrations (2 and 4%) of Ta were used in fixed amounts of CS and CuO to examine their catalytic activity and antimicrobial potential. For critical analysis, synthesized NRs were systematically examined using XRD, FTIR HRTEM, EDS, UV-Vis and PL spectroscopy. The XRD technique revealed the monoclinic structure of CuO while an increase in its crystallite size (from 15.5 to 18.5 nm) was observed upon doping. FTIR spectra were examined to study the functional groups of CuO where peaks at 514 cm−1 and 603 cm−1 confirmed the formation of CuO NRs. PL spectra depicted the charge transfer efficiency of the synthesized samples. The presence of dopants (Ta and CS) and constituent elements (Cu, O) was detected using EDS spectra. Additionally, the pH based catalytic performance of fabricated NRs revealed 99.7% dye degradation of toxic methylene blue (MB) dye in neutral media, 99.4% in basic media and 99.5% in acidic media along with promising antibacterial activities for Gram negative/positive bacteria, respectively upon doping of Ta (4%) into CS/CuO. The adsorption energies of CuO co-doped with CS/Ta led to the creation of stable structures that were investigated theoretically using density functional theory.

Shape controllable MoS2 nanocrystals prepared by the single precursor route for electrocatalytic hydrogen evolution

MoS2 has attracted great attention as a prospective electrocatalyst for generating hydrogen via water electrolysis due to its abundant and inexpensive sources. However, bulk MoS2 has weak electrocatalytic activity because of its low electrical conductivity and few edge-active sites. Controllable synthesis of MoS2 with ultrasmall size or complex morphology may be an available strategy to boost its conductivity and edge-active sites. Herein, a facile single-precursor strategy was developed to prepare nanoscale MoS2 with various morphologies, including quantum dots, nanorods, nanoribbons, and nanosheets. In-depth studies show that the formation of MoS2 with various shapes is determined by both kinetic and thermodynamic factors such as reaction time and temperature. Electrocatalytic tests reveal that MoS2 quantum dots have high electrocatalytic performance with a low overpotential of 255 mV and a small Tafel slope of 66 mV dec−1 due to the abundant exposed active edges and excellent intrinsic conductivity.

Optimal Charging Scheduling and Management with Bus‐Driver‐Trip Assignment considering Mealtime Windows for an Electric Bus Line

Compared to a charging scheduling and management problem characterized by predetermined trip assignment, this study takes bus and driver scheduling into account, and mealtime windows must be guaranteed as one of the major labor regulations. A discretized mixed‐integer linear programming (MIPL) model is developed based on a single electric bus route. We aim to obtain fast and high‐quality global solutions for this problem, and the model can be easily executed by bus operators by directly invoking an available optimization solver such as IBM ILOG CPLEX. We test our model on a real round‐trip bus route. Numerical experiments show that CPLEX takes approximately 6 sec to obtain an optimal solution. The model can not only reasonably arrange daily trips for each electric bus and driver but also effectively determine the optimal charging schedule and management for an electric bus line. Besides, we analyze the sensitivity of the key parameters in the model. With the increase in the drivers’ maximum workload, the drivers’ average idle time decreases by approximately 11.25%. The objective value decreases by approximately 38.71% and 40.04% with increases in the battery capacity and fleet size, respectively, and the objective value increases by approximately 30.06% with the decrease in the initial battery driving range. In addition, we compare the effectiveness of our time discretization modeling method in solving the same case study to that from other similar studies, and the validity of our method can be verified by the calculation time. We also compare the computational efficiency of CPLEX in solving the same case study problem with and without implementing valid inequalities, and the computational efficiency of the valid inequality method is greatly improved. Finally, through the testing of a multiline network, the potential application of the model to a large‐scale traffic network is verified.

Single source precursor route for the first graphene oxide-Pd6P nanocomposite: application in electrochemical hydrogen evolution reaction.

For the first time, Pd6P has been synthesised using a simple, straightforward and one-pot method i.e., thermolysis of a Pd(II) complex of a bidentate (P, N) organophosphorus ligand (anthracene-9-yl-CHN-CH2CH2-PPh2). The electrocatalyst (obtained after grafting nanospheres of Pd6P over layers of graphene oxide) shows high activity in electrochemical hydrogen evolution reactions (HER) with an overpotential of 133 mV to drive 10 mA cm-2 of cathodic current density. The GO-Pd6P nanocomposite is robust and effective for a continuous HER run for up to 16 hours.

GREEN SYNTHESIS OF CHROMIUM OXIDE NANOPARTICLES USING CHROMIUM (III) COMPLEX AS A SINGLE ROUTE PRECURSOR: ANTI-OXIDANT ACTIVITY

Green synthesis of metallic nanoparticles using plant sources has become an excellent substitute for conventional chemical synthetic methods. Nowadays, nano biotechnology is growing at a very fast rate due to its various possible application in the pharmaceutical biomedical, textile, paper industries. In our study, we have reported the green synthesis of chalcogenide nanostructure pharmacologically active chromium oxide (Cr2O3) nanoparticles using synthesized chromium (III) complex as a single route precursor. The synthesized chromium (III) complex was reacted with an aqueous extract of cinnamon bark for the green synthesis of Cr2O3 nanoparticles. In the present study, we aimed to synthesize chromium oxide nanoparticles (Cr2O3 NPs) through a facile low-cost, eco-friendly route. In this method, we use the aqueous environment for green synthesize of Cr2O3 NPs because the use of an aqueous medium plays a very important role in reducing time, reducing minimum possibilities of side reactions and proper execution of conversions of synthesized Cr(III) complex into a good quality of Cr2O3 NPs in a very less time. The synthesized chromium (III) complex and green synthesized Cr2O3 NPs were thoroughly analyzed through various structural, morphological, electronic, vibrational and pharmacological characterization techniques. Powdered X-ray diffraction studies confirm the formation of well-defined equip spaced crystalline nanoparticles of chromium oxide. Transmission electron microscopy exhibits oval-shaped structure of Cr2O3 NPs with an average particle size of 48 nm. Sharp electronic absorptions ends at 345nm for Cr(III) complex and at 429nm indicates the synthesis of good quality of chromium(III) complex and Cr2O3 NPs. The FT-IR spectral studies confirmed the presence of Cr-O stretching, N-H bonding and C=O stretching vibrations in synthesized Cr(III) complex was performed to investigate the thermal stability of the complex. The Cr(III) complex is stable up to 350ºC. The effective pharmacological activities like in vitro antimicrobial and antioxidant activities explained the presence of strong electron-withdrawing and electronwithdrawing groups in synthesized chromium (III) complex. The green synthesis of Cr2O3 NPs via aqueous extract of cinnamon back in proper stoichiometric ratio is a good method for synthesizing highly effective bioactive agents which will be considered as a good drug candidate for various biological applications in future for various biomedical applications

Efficacy of regional blocks or local anaesthetic infiltration for analgesia after caesarean delivery: a network meta-analysis of randomised controlled trials.

Caesarean delivery is common and can cause severe postoperative pain but injection of local anaesthetic at various sites for regional blocks or local anaesthetic infiltration may reduce this. We aimed to compare and rank these sites. We searched PubMed, Google Scholar, EMBASE and CENTRAL to June 2021 for randomised controlled trials and performed a random-effects Bayesian model network meta-analysis. The primary outcome was dose of parenteral morphine equivalents in the first 24 postoperative hours. We used surface under cumulative ranking probabilities to order techniques. We analysed 114 trials (8730 participants). The ordered mean (95% credible interval) reduction in morphine equivalents, from 34 mg with placebo, were as follows: ilio-inguinal 15 (1-32) mg; ilio-inguinal-iliohypogastric 13 (6-19) mg; transversalis fascia 11 (4-26) mg; erector spinae 11 (10-32); transverse abdominis 9 (4-13) mg; wound catheter infusion 8 (2-15) mg; quadratus lumborum 8 (1-15) mg; wound infiltration 8 (2-13) mg; and no intervention -4 (-10 to 2) mg. Ordered efficacies for injection sites were different for other relevant outcomes, including pain (to 4-6 h and to 24 h) and time to rescue analgesia: there was no single preferred route of injection. The ordered mean (95% credible interval) reduction in dynamic pain scores (0-10 scale) at 24 h compared with placebo were as follows: wound infusion 1.2 (0.2-2.1); erector spinae 1.3 (-0.5 to 3.1); quadratus lumborum 1.0 (0.1-1.8); ilio-inguinal-iliohypogastric 0.6 (-0.5 to 1.8); transverse abdominis 0.6 (-0.1 to 1.2); wound infiltration 0.5 (-0.3 to 1.3); transversalis fascia -0.8 (-3.4 to 1.9); ilio-inguinal -0.9 (-3.6 to 1.7); and no intervention -0.8 (-1.8 to 0.2). We categorised our confidence in effect sizes as low or very low.

Selectivity and molecular stress responses to classical and botanical acaricides in the predatory mite Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae).

Acaricide application remains an integral component of integrated pest management (IPM) for the two-spotted spider mite Tetranychus urticae. Species and strains of phytoseiid predatory mites vary significantly in their response to acaricides. For the success of IPM, it is imperative to identify the determinants of selectivity and molecular stress responses of acaricides in predatory mites. The three classical acaricides bifenazate, cyflumetofen, and fenbutatin oxide did not affect the survival and fecundity of Phytoseiulus persimilis regardless of the route of exposure. Selectivity of the orange oil and terpenoid blend-based botanical acaricides was low via a combination of direct exposure, acaricide-laced diet, and residual exposure but improved when limiting exposure only to diet. To gain insights into the molecular stress responses, the transcriptome of P. persimilis was assembled. Subsequent gene expression analysis of predatory mites orally exposed to fenbutatin oxide and orange oil yielded only a limited xenobiotic stress response. In contrast, P. persimilis exhibited target-site resistance mutations, including I260M in SdhB, I1017M in CHS1, and kdr and super-kdr in VGSC. Extending the screen using available Phytoseiidae sequences uncovered I136T, S141F in cytb, G119S in AChE, and A2083V in ACC, well-known target-sites of acaricides. Selectivity of the tested botanical acaricides to P. persimilis was low but could be enhanced by restricting exposure to a single route. Differential gene expression analysis did not show a robust induced stress response after sublethal exposure. In contrast, this study uncovered target-site mutations that may help to explain the physiological selectivity of several classical acaricides to phytoseiid predators.
