Unravelling the Current Status of Rice Stripe Mosaic Virus: Its Geographical Spread, Biology, Epidemiology, and Management

Rice stripe mosaic virus (RSMV) belongs to the Cytorhabdovirus species in the Rhabdoviridae family. Recently, RSMV was widely spread in East Asia and caused severe yield losses. RSMV is transmitted by the planthopper vectors, Recilia dorsalis, Nephotettix virescens, and Nilaparvata lugens, that mostly affect rice. The adult vectors can hibernate, transmit the virus, lay eggs on rice plants, and, finally, multiply in subsequent generations, resulting in new infection outbreaks. RSMV-infected rice varieties display striped mosaicism, mild dwarfism, stiff and twisted leaves, delayed heading, short panicles with large unfilled grains, and yield reduction. In nature, the infection of multiple pathogens in the same host is widespread, which is defined as co-infection. It can be antagonistic or synergistic. Pathological synergistic effects between RSMV and other viruses can generate strains with new genetic characteristics, leading to unpredictable epidemiological consequences. After the first identification of RSMV in 2015, significant advancements in understanding the disease’s characteristics, symptoms, cycles, geographic distribution, potential vectors, and synergistic interaction, as well as its management strategies, were developed. To reduce the damage due to RSMV infection, many scientists have recommended pest control techniques to target adult vectors. It is also essential to confirm the actual time of monitoring, development of resistant varieties, and changes in cultivation systems. Due to the limitations of the conventional plant disease control technologies, improvements in efficiency and safety are in high demand. Therefore, to find efficient and environmentally safe controls to mitigate these challenges, reviews of research are the foremost step. In this review, we summarize the basic epidemiological information about the origin of RSMV and its infection symptoms in the field, synergistic interaction with viruses during co-transmission, yield losses, formulation of the disease cycle, and control strategies from several case studies. Finally, we recommend the formulation of the disease cycle and management strategies of RSMV infection.

Comparation of pheromone-binding proteins 1 and 2 of Spodoptera frugiperda in perceiving the three sex pheromone components Z9-14:Ac, Z7-12: Ac and Z11-16: Ac

Pheromone-binding proteins (PBPs) are mainly responsible for binding and transporting hydrophobic pheromone molecules across the aqueous sensilla lymph to the receptor proteins. The preference of each PBP is believed to be different for each pheromone component within a single species. Significantly higher expression level of PBP1 and PBP2 in the male antennae of Spodoptera frugiperda suggesting that SfruPBP1 and SfruPBP2 might play important roles in pheromone perception. However, the preference of these two PBP to the three main pheromone components Z9-14: Ac, Z7-12: Ac and Z11-16: Ac have not been determined. In this study, a fluorescence competitive binding assay revealed that the binding intensities of SfruPBP1 and SfruPBP2 to Z9-14: Ac or Z7-12: Ac was comparable. We then used the CRISPR/Cas9 system to individually or simultaneously knock out PBP1 and PBP2 in S.frugiperda. The result of courtship behavior indicated that SfruPBP1 and SfruPBP2 were indispensable and played equal roles in perceiving the pheromones Z9-14: Ac and Z7-12: Ac for orientation, wing vibration, and hair-pencil display. Compared with Z9-14:Ac and Z7-12: Ac, Z11-16: Ac showed higher or medium binding intensities with SfruPBP1 and SfruPBP2 but played a minor role in inducing the wing vibration behavior. The results of this study are valuable for elucidating the mechanisms involved in sex pheromone perception and may facilitate the development of PBP-targeted pest control techniques.

OBP83b and OBP49a Involved in the Perception of Female-Derived Pheromones in Bactrocera dorsalis (Hendel).

In Bactrocera dorsalis, both males and females release chemical signals to attract mates. In our previous study, we identified ethyl laurate, ethyl myristate, and ethyl palmitate as potent female-derived pheromones that contribute to mate attraction. However, the mechanisms underlying the olfactory recognition remain unclear. In this study, we observed strong antennal and behavioral responses in male B. dorsalis to these female-derived pheromones, and further investigation revealed significant upregulation of OBP49a and OBP83b following exposure to these compounds. Through fluorescence competitive binding assays and RNA interference techniques, we demonstrated the crucial roles of OBP49a and OBP83b in detecting female-derived pheromones. Finally, molecular docking analysis identified key residues, including His134 in OBP83b and a lysine residue in OBP49a, which formed hydrogen bonds with female-derived pheromones, facilitating their binding. These findings not only advance our understanding of olfactory recognition of pheromones in B. dorsalis but also offer potential targets for developing olfaction-interfering techniques for pest control.

Integrated Pest Management: Success Stories and Key Takeaways

Integrated Pest Management (IPM) has revolutionized pest control in various agricultural settings, including orchards. By blending cultural, biological, and chemical methods, IPM aims to minimize pest damage while reducing environmental and health impacts. One of the most successful strategies within IPM is mating disruption, which uses synthetic pheromones to confuse male insects and prevent them from finding mates. This technique has been particularly effective against pests like the codling moth in apple and pear orchards, significantly reducing insecticide use by up to 90% in some regions.The implementation of IPM in orchards has numerous long-term advantages. Lower manufacturing costs, less environmental contamination, and increased worker safety have all resulted from reduced pesticide use. Furthermore, a healthier ecological balance has been promoted by the rise in natural predators and parasitoids brought about by the decrease in chemical treatments. Many growers have reported greater fruit quality due to more targeted pest control and healthier trees, despite worries that reduced use of pesticides would harm fruit quality. Important pests have also been suppressed regionally as a result of IPM's efficacy, such as the codling moth in the Pacific Northwest, whose populations have dropped to the point where little intervention is needed. Economic assessments highlight IPM's financial sustainability by demonstrating considerable long-term cost savings. According to one study, IPM adopters in apple orchards in Nova Scotia had 25% reduced pest management expenses over a ten-year period than those using conventional approaches. These results demonstrate how integrated pest management (IPM) has the ability to provide long-term, efficient pest control that is advantageous to growers, the environment, and consumers alike. IPM's widespread use attests to its effectiveness and sustainability. Integrative pest management (IPM) ensures the long-term health and production of agricultural systems by combining various pest control techniques into a balanced solution that satisfies both ecological and financial requirements.

A Web Application that Classifies Rice Crop Stress with Recommendation System

It provides for the development and evaluation of a web-based application meant to aid in the identification of rice crop stress and possible mitigation measures. Traditional methods have been used, but this approach should replace the manual classification that is time-consuming, tedious, and complex, as it leverages advanced machine learning algorithms to analyze images of rice crops, resulting in the accurate detection of various stress factors such as nutrient deficiencies, pest’ infestations, and water stress. In order to ensure the system has high accuracy and reliability for real-world situations, training and testing were conducted using an inclusive dataset that contained labeled images that featured different kinds of stressed rice crops. Also, besides the classification of stress, the app recommends specific advice for particular stress types, such as fertilization, pest control, and irrigation techniques. The recommendations are generated from a massive database with expert agricultural tips and current research to ensure that they give accurate and practical solutions. The usability and effectiveness of the application were assessed through field trials with local farmers and agricultural experts. Results indicated a significant improvement in the early detection and management of crop stress, leading to increased yields and resource efficiency. This web application aims to empower farmers with timely and accurate information, foster sustainable agricultural practices, and enhance food security.

The Southern Magnolia, Southern Red Oak, and Live Oak showed symptoms of stress, such as leaning and decay. The identified Loblolly Pine showed symptoms such as bark beetle infestations and resource competition. For each of these species, specific indicators of stress were identified and recommended management approaches. These include the installation of support systems, pruning of diseased branches, soil tillage, and pest control techniques. These practices allow the strengthening of urban forest, which ensures continued health and functioning of our ecosystems.

Gonadal transcriptome analysis of genes related to sex differentiation and sex development in the Pomacea canaliculata

As an invasive alien animal, Pomacea canaliculata poses a great danger to the ecology and human beings. Recently, there has been a gradual shift towards bio-friendly control. Based on the development of RNA interference and CRISPR technology as molecular regulatory techniques for pest control, it was determined if the knockout of genes related to sex differentiation in P. canaliculata could induce sterility, thereby helping in population control. However, the knowledge of sex differentiation- and development-related genes in P. canaliculata is currently lacking. Here, transcriptomic approaches were used to study the genes expressed in the two genders of P. canaliculata at various developmental stages. Gonad transcriptomes of immature or mature males and females were compared, revealing 12,063 genes with sex-specific expression, of which 6066 were male- and 5997 were female-specific. Among the latter, 581 and 235 genes were up-regulated in immature and mature females, respectively. The sex-specific expressed genes identified included GnRHR2 and TSSK3 in males and ZAR1 and WNT4 in females. Of the genes, six were involved in reproduction: CCNBLIP1, MND1, DMC1, DLC1, MRE11, and E(sev)2B. Compared to immature snail gonads, the expression of HSP90 and CDK1 was markedly reduced in gonadal. It was hypothesized that the two were associated with the development of females. These findings provided new insights into crucial genetic information on sex differentiation and development in P. canaliculata. Additionally, some candidate genes were explored, which can contribute to future studies on controlling P. canaliculata using molecular regulatory techniques.

Simultaneous use of Beauveria bassiana and Bacillus subtilis-based biopesticides contributed to dual control of Trialeurodes vaporariorum (Hemiptera: Aleyrodidae) and tomato powdery mildew without antagonistic interactions

BackgroundImplementing pest and disease control techniques that have low environmental impact is important for sustainable agriculture. Microbial biopesticides are an effective approach due to their low environmental impact and low risk of resistance development. Because it is not usually possible to control multiple pests and diseases with a single microbial biopesticide, it is essential to investigate the potential for combining microbial biopesticides with varying control spectrums effectively. Many biopesticides have antimicrobial activity and may therefore interact negatively in combination.ResultsThis study demonstrated that a mixture of Beauveria bassiana and Bacillus subtilis formulations proved potential for simultaneous control of greenhouse whitefly (Trialeurodes vaporariorum Westwood) and tomato powdery mildew (Oidium neolycopersici). Three greenhouse experiments were conducted to assess the efficacy of mixed and single-use treatments. A laboratory experiment comparing the insecticidal effect of each treatment was also conducted. In all greenhouse experiments, the combined treatment controlled the greenhouse whitefly (78.9–88.3%) and tomato powdery mildew (47.2–81.0%) compared to untreated controls, which was as well as each treatment alone. In some greenhouse and laboratory experiments, the mixed treatment showed an approximately 1.32 to 1.78 times higher insecticidal effect compared to single-use treatments. Regarding the control efficacy against the pest and disease, negative effects of microbial agents on each other were not observed.ConclusionsThese results demonstrated the effectiveness of concurrent use of two microbial pesticides examined on dual control of pest and disease and showed potential for improved control of certain pests. The knowledge of this work could suggest the possibility of more environmentally friendly pest control systems with the use of microbial pesticides.

Effectiveness Of Liquid Smoke from Oil Palm Solid Waste Against Spodoptera frugiperda (lepidoptera: noctuidae)

Indonesia is one of the largest producers of palm oil commodities in the world. Massive palm oil production to meet high demand can pose risks in increasing waste production. The processing of solid palm oil waste into liquid smoke through pyrolysis is carried out as an effort to mitigate environmental damage caused by greenhouse gases. Components in liquid smoke can be utilized as natural insecticides. This research aims to determine the potential of liquid smoke from solid palm oil waste, namely fiber and frond, to control Spodoptera frugiperda. The testing method uses a Randomized Complete Block Design (RCBD) with 11 treatments repeated three times. Liquid smoke application is done by dipping the feed, which is then given to S. frugiperda instar II. The results show that liquid smoke from fronds causes higher mortality in S. frugiperda compared to liquid smoke from fibers. At a concentration of 4%, liquid smoke from fronds and fibers caused S. frugiperda mortality of 63.33% and 40%, respectively. Liquid smoke application also suppressed feed consumption by 72.98% lower than the control and caused an extension of time from instar II-VI at the 4% application concentration. The use of liquid smoke from palm fronds and fibers can be used as an insecticide as one of the pest control techniques and a solution for utilizing palm oil waste.

Cannibalistic enemy-pest model: effect of additional food and harvesting.

Biological control using natural enemies with additional food resources is one of the most adopted and ecofriendly pest control techniques. Moreover, additional food is also provided to natural enemies to divert them from cannibalism. In the present work, using the theory of dynamical system, we discuss the dynamics of a cannibalistic predator prey model in the presence of different harvesting schemes in prey (pest) population and provision of additional food to predators (natural enemies). A detailed mathematical analysis and numerical evaluations have been presented to discuss the pest free state, coexistence of species, stability, occurrence of different bifurcations (saddle-node, transcritical, Hopf, Bogdanov-Takens) and the impact of additional food and harvesting schemes on the dynamics of the system. It has been obtained that the multiple coexisting equilibria and their stability depend on the additional food (quality and quantity) and harvesting rates. Interestingly, we also observe that the pest population density decreases immediately even when small amount of harvesting is implemented. Also the eradication of pest population (stable pest free state) could be achieved via variation in the additional food and implemented harvesting schemes. The individual effects of harvesting parameters on the pest density suggest that the linear harvesting scheme is more effective to control the pest population rather than constant and nonlinear harvesting schemes. In the context of biological control programs, the present theoretical work suggests different threshold values of implemented harvesting and appropriate choices of additional food to be supplied for pest eradication.

Plants and age-structured pest dynamics with natural enemy as control strategy: A fractional differential equations model

In recent years, plant pests have drawn much attention from researchers. Biological control proved an efficient replacement for chemical and other pest control techniques. The present study proposes the cognition of an immature pest population unaffected by the natural enemy and grows exponentially by the harvesting effort of the mature pest population to plants. The fractional calculus environment proposes A four-compartment: plant, immature and mature pest, and natural enemy model. Equilibrium points and the system’s stability are studied theoretically and numerically. Simulation study for different values of fractional order generates the optimum solution. The suggested method is much more benignant than the existing method of ordinary differential equations as we can figure out the infrequent changes in the variable using a fractional derivative. Creating the memory effect in the system using fractional derivatives makes it more realistic.
