The ethnographic museum as a sensitive translation

Abstract This article analyzes the recently renewed, permanent exhibition of the Royal Museum for Central Africa (AfricaMuseum) in Tervuren, Belgium. The museum is seen as a translational space, considering the parallels between, on the one hand, curatorial strategies to represent cultural otherness and, on the other, processes of cultural and interlingual translation (Sturge 2007). We draw on an interdisciplinary mindset of translation as change and choice, as a multimodal and multimedial activity, and as an inevitably meaning-transforming process. Pressured to keep pace with the rapidly evolving public debate on decolonization, the curators-translators of the AfricaMuseum are aware that they are dealing with “sensitive texts” (Simms 1997) and have, accordingly, adopted a set of strategies to reduce perceived “translation risks” (Pym and Matsushita 2018). The article explores these strategies at three levels of translation operating in the museum: cultural, intersemiotic, and interlingual. In particular, we reveal the inherent tensions in the current display by discussing scenographic interventions that undermine the decolonization efforts in a number of galleries. These tensions are conceptualized as incomplete or incoherent forms of translation and illustrate the “work in progress” in the AfricaMuseum.

Incidence and damage of the ambrosia beetle on cocoa plants in East Luwu District, South Sulawesi, Indonesia

Abstract. Nuriadi, Sjam S, Gassa A, Dewi VS. 2023. Incidence and damage of the ambrosia beetle on cocoa plants in East Luwu District, South Sulawesi, Indonesia. Biodiversitas 24: 3592-3600. The attack of ambrosia beetle on cocoa plants (Theobroma cacao L.) in East Luwu District, South Sulawesi Province, was first reported in 2020 at the Wotu sub-district. However, there was no information on its intensity and the number of affected sub-districts. A survey and data collection were conducted from January to July 2021 by selecting a 1 hectare area from 7 out of the 11 affected sub-districts identified in the preliminary study. The parameters observed were attack intensity, the number of galleries in stems and branches, and the number of trapped ambrosia beetle. The results showed that the attack of the ambrosia beetle on cocoa plants in the 7 sub-districts ranged from moderate to severe intensity, causing damage to mature plants and seedlings. It was observed that the number of galleries was higher on stems than on branches. The intensity of attacks on cocoa plants aged 23-27 years is higher than the cocoa aged 8-15 years. Additionally, the obtained species of ambrosia beetle are Xylosandrus sp.1 (Coleoptera: Curculionidae), Xylosandrus sp.2 (Coleoptera: Curculionidae), Xyleborus sp. (Coleoptera: Scolytidae) and Hypothenemus sp. (Coleoptera: Scolytidae). The results are expected to provide important information about the invasion of the ambrosia beetle and the prevention steps of its spread on cocoa plantations in South Sulawesi.

Efficacy of some entomopathogenic fungi against tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)

BackgroundEffects of entomopathogenic fungi (EPF); Beauveria bassiana, Isaria fumosorosea and Pupureocillium lilacinum against tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), which is one of the most economic pests of tomato, were investigated in Petri dish, pot and greenhouse experiments. Commercial bioinsecticide Met 52 was also used in the experiments. In the Petri dish trials, I. fumosorosea applied to the third instar larvae by dipping method was recorded as the most effective entomopathogen, while the efficacy of B. bassiana was high in the spray and residue methods. In the pot experiments, entomopathogenic fungi were applied to tomato plants before and after infestation with T. absoluta.ResultsAs a result of the applications, it was found that the EPF significantly reduced the formation of galleries on tomato leaves when applied before or at the beginning of tomato leafminer infestation. In the greenhouse experiments a registered insecticide Voliam Targo was also applied. All applications significantly reduced the numbers of galleries on tomato leaves than in the control plants, in both greenhouse trials, made in Antalya and Isparta Provinces. I. fumosorosea was the most effective one among the tested 3 EPF.ConclusionsIn this study, it was determined that the EPF B. bassiana and P. lilacinum can reduce tomato leafminer damage, while the efficacy of I. fumosorosea was the highest, and especially after two applications it was nearly effective as the registered insecticide.

Integration of Control Strategies to Optimize Management of Ambrosia Beetles (Coleoptera: Curculionidae, Scolytinae) and Phytophthora Root Rot (Peronosporales: Peronosporaceae) in Flowering Dogwoods (Cornalaes: Cornaceae) After Simulated Flooding.

Ambrosia beetles (Coleoptera: Curculionidae, Scolytinae) and Phytophthora root rot (Peronosporales: Peronosporaceae) cause significant damage to the ornamental industry in the United States. In this study, mefenoxam (fungicide), permethrin (insecticide), and charcoal + kaolin were used in different combinations with Phytophthora cinnamomi (Rands: Peronosporales: Peronosporaceae) inoculated and noninoculated plants to optimize the management of ambrosia beetles and Phytophthora root rot. Treatment applications were performed in two trials on 1 (mefenoxam, drench), 18 (P. cinnamomi inoculation), or 19 (permethrin, spray) days before instigating flood stress or 2 d after flood stress (charcoal + kaolin, spray), respectively. Flooding was maintained for 21 d. Ambrosia beetle attacks and plant growth data were recorded. Tree roots were rated at study end for disease severity and root samples were plated on PARPH-V8 medium to determine the percentage of pathogen recovery. In both trials, the combination of mefenoxam + permethrin treatment had reduced disease severity and ambrosia beetle attacks compared to the inoculated controls. Permethrin-treated trees had shorter galleries compared to controls in trial 1 and no gallery formation in trial 2. In both trials, no differences were observed among the treatments in numbers of galleries with eggs and adults, but mefenoxam + charcoal + kaolin had significantly fewer galleries with larvae among the noninoculated trees compared with the respective control in trial 1. Overall, treatments containing combinations of mefenoxam + permethrin had reduced disease severity and ambrosia beetle attacks.

Invasive Populations of the Emerald Ash Borer Agrilus planipennis Fairmaire, 1888 (Coleoptera: Buprestidae) in Saint Petersburg, Russia: A Hitchhiker?

Simple SummaryThe emerald ash borer (EAB) is an invasive beetle of Asian origin that has killed millions of ash trees in North America and Russia, with a devastating economic and ecological impact. In September 2020, EAB was detected for the first time in Saint Petersburg, Russia, notably killing ash trees. The invasion came from the eastern direction (Moscow) and became a significantly notable event for Saint Petersburg, famous for its historical parks. Moreover, Saint Petersburg is 120–130 km from the eastern EU borders of Estonia and Finland, with railway, motorway, and ferry connections. Currently, EAB is one of the most serious quarantine insect pests in the EU. There is a risk that the eventual EAB invasion could potentially extirpate European populations of ash. Currently, 95% are devastated by the invasive fungal disease ash dieback. Here, we investigated the development of EAB populations in Saint Petersburg, from its initial invasion (estimated year 2015), until 2021. We found that climatic conditions of north Russia do not favor the natural aerial spread of EAB. The two isolated populations were located, respectively, close to a motorway, and the Neva River (used for cargo shipping), implying that the insect spreads by transport vehicles, or “hitchhiking”. This could potentially lead to the eventual invasion of the EU by this serious, tree-killing beetle.The emerald ash borer (EAB), Agrilus planipennis, is an invasive beetle of East Asian origin that has killed millions of ash trees (Fraxinus spp.) in North America and Russia. In September 2020, EAB was detected in Saint Petersburg, a notable event for the metropolitan city. The aim of the present study was to investigate the occurrence and ecology of EAB in Saint Petersburg. The presence of two distinct enclave populations of EAB was revealed, each of which has, most likely, been established through separate events of “hitchhiking” via transport vehicles. Following the invasion, the further spread of EAB in Saint Petersburg was slow and locally restricted, most likely due to climatic factors. This spread by “hitchhiking” suggests that the possibility of the further long-distance geographic spread of EAB in the Baltic Sea region (the EU) is high, both by ground transport (120–130 km distance from EU borders) and ferries that transport cars across the Baltic Sea. In certain cases, the development of EAB on Fraxinus excelsior, based on the stem portion colonized, larval densities, number of galleries, exit holes, viable larvae, and emerged adult beetles, was more successful than in Fraxinus pennsylvanica trees. The observed relatively high sensitivity of F. excelsior to EAB, therefore, casts doubt on the efficacy and benefits of the currently ongoing selection and breeding projects against ash dieback (ADB) disease, which is caused by the fungus Hymenoscyphus fraxineus. Inventory, mapping, and monitoring of surviving F. excelsior trees infested by both ADB and EAB are necessary to acquire genetic resources for work on the strategic long-term restoration of F. excelsior, tackling the probable invasion of EAB to the EU.

Assessment of Tuta absoluta yield loss in Iranian tomato crops

• The South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a major invasive pest of tomato. • The weight and percentage of infected fruits was negatively related to different initial infestation levels of Tuta absoluta . • Investigating crop loss of T. absoluta in the farm is essential for enhancing integrated pest management programs. The South American tomato pinworm, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), a devastating pest of tomato plants, originates from South America but it has been considered an invasive pest for Iran since 2010. To assess crop loss caused by this pest, a study was conducted in a 600 m 2 field under a randomised complete block design. The impact of different initial densities of T. absoluta , including control (without infestation), one, two, four, and eight T. absoluta eggs on each host plant in the first and second year was investigated with an additional treatment (16 pinworm eggs per host plant) used in the second year. Yield attributes including length and width of fruits, numbers of infested and intact fruits along with their weights were sampled and assessed on a weekly basis. In addition, the correlation between the number of galleries and these characteristics was also investigated. Crop loss data demonstrated that the effect of different infestation levels on fruit size and the weight of intact fruits was not significant over both years. However, the effect of treatment on the percentage and weight of infested fruits was shown to be significantly different in 2014 and 2015. Furthermore, there was a negative significant correlation between the number of galleries and weight of infested fruits in both years. Collectively, these results will be useful for enhancing pest management programs of T. absoluta in Iran.

О новом подходе в оценке поведения большой совокупности параллельных штолен

The problem of assessing the behavior of a large number of underground structures such as parallel tunnels, characteristic of mines for the extraction of minerals, including coal, is considered. Traditionally, studies are performed for a single object, and then the parameters found are accepted for all other objects. At the same time, the multiplicity of such objects can lead to another factor of strength impairment associated with the possibility of localization of the stress-strain state in one of the zones of the structure, leading to excess of the planned strength parameters. In this paper, the theory of calculation of strength properties of such objects is based on the example of underground structures. The research is based on the block element method based on factorization approaches. The problem is reduced to a system of integral equations of the first kind with a difference kernel, which is reduced to a system of Fredholm integral equations of the second kind. By calculating the integrals describing the nuclei of these equations according to the theory of deductions, it is possible to reduce the integral equations to a system of algebraic equations available for analytical analysis, which allows to identify the localization of stresses or displacements. The long-range approach made it possible to find a connection between these equations with the Riemann problem for a set of pairs of analytic functions, the number of which coincides with the number of galleries. In earlier works, the resulting stress-strain state was characterized by calculating only the vertical contact stresses on the supports and the vertical displacements of roof slack charges. In this paper, it is possible to construct an approach that allows us to calculate all three components of the stresses on the supports and all three components of the roof sagging displacement.

Being an artist: a profession or a vocation? Socially engaged art by Joanna Rajkowska

The problem of the condition of artists in Poland is rarely addressed in public debate, which is particularly surprising in the world of growing disproportion between rapid development of the art market (the number of galleries, rising prices of auctioning) and still financially unstable and difficult situation of artists. The paper attempts to look at the economic and social status of Polish artists through the analysis of the artistic work of a Polish artist Joanna Rajkowska who tries to find her position in the socio-economic system, without giving up her creative activity. At the end of the paper the author will try to answer the question whether socially engaged art can bring about major changes in the system of financing art.

Resistance to the cabbage root fly, Delia radicum (Diptera, Anthomyiidae), of turnip varieties (Brassica rapa subsp. rapa)

The cabbage root fly Delia radicum L. (Diptera: Anthomyiidae) is one of the major pests of many Brassica crops in the temperate areas of Europe and North America. At present, turnip (B. rapa ssp. rapa L.) varieties resistant to the pest does not exist. With the aim to fill this gap, a no-choice tolerance test of 56 accessions among turnips, turnip tops and turnip greens was performed under controlled conditions by introducing D. radicum eggs. Plant survival, leaf and root conditions, pupae number and weight significantly varied among plant accessions. Ten putatively resistant and ten susceptible accessions (control group) were selected from this first screening, transplanted in the field and exposed to natural infestation to detect antibiosis and antixenosis mechanisms. Both in the laboratory and in the field, pupae number significantly varied within accessions and between resistant and susceptible group, although pupal weight did not, indicating the absence of antibiosis effect on this early stage. In the field, the number of galleries was significantly lower in the resistant group in comparison with the control. Resistant accessions had smaller size, and a smaller, white and mostly buried root. Within the resistant and susceptible accessions, larger plants harboured more pupae, however purple roots were those most preferred, and the hosted pupae weighed most. Three accessions from the resistant group (MBGBR0178, MBGBR0570 and MBGBR0371) stand out for resistance to D. radicum possibly through antixenosis mechanisms.

Stem damages caused by heart rot and large poplar borer on hybrid and European aspen

Abstract Solid wood production of hybrid aspen requires relative longer rotation periods, thus increasing risk of wood damages by pests and diseases. We compared damages by heart rot and poplar borer of 48 years old hybrid (Populus tremuloides Michx. × P. tremula L.) and European aspen in a progeny trial located in Eastern part of Latvia. Trees were harvested and rot patches and galleries were recorded and measured at a stump level. The number of galleries had positive relation on number of patches and total area of rot. The susceptibility of the rot and poplar borer was similar for both hybrid and European aspen. Yet, some differences among families were detected. No effect of pathogens damage was observed on the tree growth. Larger trees had smaller proportion and incidence of rot and galleries per unit of area as well as wider outer rot-free wood layer.

Classification of Stability of Highwall During Highwall Mining: A Statistical Adaptive Learning Approach

The depleting coal deposits day by day required the introduction of novel methods of mining like highwall mining. Highwall mining is a method of extraction of coal blocked in the highwall. The method involves considerable challenges in the area of roof control and most importantly the stability of the highwall itself. Highwall mining has gained considerable importance all over the world, owing to the fact that the coal otherwise would not be extracted forever. This paper aims to assess the influence of varying conditions which can affect the stability of the highwall during highwall mining. The effect of gallery length, width of pillar and number of galleries are systematically studied through field investigations where a highwall mining was adopted first time in India. Initially, assessment was carried out using a numerical modelling approach and then the stability of the highwall is classified using multilinear regression, logistic regression and naive Bayes classifier. This will provide a mechanism to predict the stability of the highwall in future cases of similar conditions. The classification is done using statistical adaptive learning methods and a comparison of the methods is done.

Local distribution and abundance of Cardisoma guanhumi Latreille, 1928 (Brachyura: Gecarcinidae) in southern Brazil.

The blue land crab, Cardisoma guanhumi Latreille, 1828 (Brachyura: Gecarcinidae) is officially included in the list of over-exploited species in Brazil, although still abundantly found in the state of Santa Catarina, the southern limit of its distribution. This species was found in forested areas, gardens, and grassy areas, including crabs with carapace width larger than 80mm. The existence of this population with these characteristics is surprising, since there is only one official record of the species in the southern region. The objectives of this study are to estimate the abundance and occupation patterns of C. guanhumi in this region. Correlations with conservation were discussed. The absolute abundance of crabs in the middle of summer activity was established for an area of 100,000 m2. A smaller area was mapped and divided into sampling units for statistical analyses. We distributed approximately 240 crabs in a forested area of about 3,000 m2 and 150 crabs in grassy areas (90,000 m2). The statistical test of Kruskal-Wallis test showed that there are significant differences between the sizes of the openings of the galleries inside the forest and that located in grassy areas. In the forest, the openings tend to be much larger. Burrows were found at a distance of 150 metres from the channel. The number of galleries was higher in the forested area, although the burrows were more densely grouped in grassy areas. Although C. guanhumi seems to be adjusting well to changes caused by human occupation, small forested areas are more conducive to growth and conservation of this species.

The Third Biennale of Sydney: ‘White Elephant or Red Herring?’

The focus of this essay is the indisputably important 1979 Biennale of Sydney, which launched Sydney's biennial as an international event seeking out adventurous art from Western Europe and the USA. We will argue that it sought both to present an image of the world of contemporary art and also, more critically, to embody a key strand of the globalising art world's emerging contemporaneity.By the end of the 1970s, the arrival of relatively affordable international flights had pushed Australian artists, along with their peers from other 'margins' of contemporary art, into closer contact with North Atlantic art centres. The result was the beginning of a Balkanisation of art worlds beyond New York and Western Europe: within each art centre, a division into two overlapping art worlds, a provincial ghetto represented by one set of commercial art galleries or an international art world enclave represented by another, usually smaller and more exclusive, number of galleries and, increasingly, some artist-run spaces.1This was as true in Tokyo as it was in Sydney or Melbourne. The two art worlds overlapped but the latter world-that which saw itself as international and part of a nascent, globalised art world-did not at that time or later necessarily renew itself from the former's talent-pool of the best and brightest, and then only reluctantly or in such a way as to reinforce North Atlantic primacy over the image of what was contemporary art. Many scholars' recent work, particularly that of John Clark, has shown that this remained true even of the huge Asian biennials that flourished from the 1990s onwards though, increasingly, many younger artists moved easily from international artist residency to residency and from biennial to biennial.2Founding the Sydney BiennaleBoth the Sao Paulo and Sydney Biennales were founded by immigrants from post-War Europe-in Sao Paulo, Francisco Matarazzo Sobrinho; in Sydney, Franco Belgiorno-Nettis. Their motivations were similar, and they had been affected by their own experiences of post-World War Π diaspora. They were European migrants who established themselves as important industrialists, proudly participating in their chosen city's civic and national desires for international recognition as nascent global cities and as nodes of business and capital in their respective regions in the Southern Hemisphere. Needless to say, civic and national aspirations were never identical nor necessarily in harmony, nor was the balance between the two always equal. Whereas the Federal Government's new Australia Council for the Arts wished primarily to support art-making nationwide and far less to project Australian art internationally. Its aim was to maximise direct support to Australian artists in the form of grants. Belgiorno-Nettis, on the other hand, wanted to replicate and import the cultural institutions of his homeland to his beloved Sydney, and in particular the venerable institution of the Biennale of Venice:My love affair with Venice, where I have been a frequent visitor for years, is the source of inspiration for the Biennale. How do you break the isolation of Australia, which I felt strongly myself in the early 50s? How do you inject that flavor of international extravaganza, originality and explosive vision that you see at gatherings in Venice, in the Giardini, in the Corderia, in the Arsenale, with their centuries of tradition?3Other biennial models than that of Venice were already available, principally the idea of a biennial of the South, current from 1955 onwards, that we have written about elsewhere.4 These ideas might just as easily have been adopted, but there is no evidence that they were discussed and Belgiorno-Nettis's civic-minded boosterism, nostalgia and philanthropy prevailed. He invented, underpinned and financially supported the new biennial with the organisational and curatorial resources provided by his family conglomerate, the powerful Transfield Corporation, which built bridges, railways and major infrastructure projects. …

Mating disruption of the ambrosia beetle Megaplatypus mutatus in poplar and hazelnut plantations using reservoir systems for pheromones

Megaplatypus mutatus (Chapuis) (Coleoptera: Curculionidae: Platypodinae) is an ambrosia beetle native to South America, but it has recently been introduced into Italy and represents a serious problem in commercial poplar and fruit tree plantations. Male M. mutatus emit a sex pheromone composed of (+)-6-methyl-5-hepten-2-ol [(+)-sulcatol], 6-methyl-5-hepten-2-one (sulcatone), and 3-pentanol. We performed three field trials of mating disruption of M. mutatus in hazelnut and poplar plantations in Argentina and Italy. To perform these tests, we made plastic pheromone reservoir-type dispensers for sulcatol, sulcatone, and 3-pentanol with zero-order kinetics that were deployed in the field during the female flight period. The number of galleries where mating took place was significantly higher in control than in treated areas, indicating that pheromone application had interfered with female behavior and male localization. Because damage reduction was >56% in both countries, these results demonstrate the potential for the strategy of pheromone-mediated mating disruption of M. mutatus in commercial poplar and hazelnut plantations. Also, our study provides the first evidence for successful pheromone-mediated mating disruption in a forest beetle.

Terrain Vague as Setting: Chinese Video in New York

© 2006 Elena Sorokina Chinese video is said to be made primarily for “domestic use” and therefore utilizes a set of internal references that can never truly translate across national boundaries. However, its first strong appearance in New York in 2004, when the Museum of Modern Art organized a series of screenings, was a huge success. A number of galleries and other venues joined MoMA in providing venues for Chinese video work. Video was widely heralded as a booming new medium in China, where younger artists were embracing the rapid production capabilities of digital cameras to comment on the unprecedented scale of transformation within Chinese metropolitan culture.

Resistance of Commercial Hybrids and Lines of Sorghum, Sorghum bicolor (L.) Moench., to Diatraea saccharalis (Fabr.) (Lepidoptera: Pyralidae)

Commercial sorghum hybrids and Embrapa's lines were evaluated regarding resistance to sugarcane borer. Two field experiments were conducted in Sete Lagoas, MG, under natural infestation, during the second cropping season in a randomized complete block with 3 replicates. The plants were evaluated regarding to stand, maturity cycle, plant height, and number of broken or lodging stalks and yield. The borer incidence, number of galleries, number of healthy and damaged nodes were also evaluated to calculate the Infestation Index and Intensity Infestation Index. Among the commercial sorghum hybrids, Br 304 and CMSXS 9701 were the least infested wile Z 732 and Esmeralda were the least damaged. Among the lines, the least infested was 9815017 and least damaged 9816003. The two indexes were correlated positively with plant height in both experiments and negatively correlated with the lines cycle. However, there was no correlation between the Indexes for the hybrids. Among the lines the data fit to a logarithmic curve. Although there is a significant variability among commercial sorghum hybrids regarding sugarcane borer susceptibility, under high borer density, a significant yield loss can be computed to all hybrids. On the other hand, the genetic variability regarding sugarcane borer resistance among the sorghum lines indicated a significant potential for use in a breeding program of resistant cultivars.

The Layer Pyramid of Zawiyet el-Aryan: Its Layout and Context

In their seminal work on the pyramids, Vito Maragioglio and Celeste Rinaldi1 point out the curious fact that the two excavators of the Layer Pyramid at Zawiyet el-Aryan,2 Alessandro Barsanti in 1900,3 and George Andrew Reisner, working with Clarence Fisher, in 1910-1 1,4 drew sections of the substructure that differ not only in detail, but in fundamental dimensions and also in the very number of galleries (fig. 1)! Furthermore, the dimensions derived from the scale drawings (or, rather, sketches) in some cases differ from the figures mentioned in the respective excavators' texts (fig. 2; table I).5 It is not possible to check the data at present, since the pyramid is both sanded up and now lies directly adjacent to a military zone. Interestingly, the Reisner-Fisher version of the pyramid's layout has seemingly been accepted by almost all subsequent pyramidwriters, presumably on the basis of the relative academic standings of the American and Italian excavators, and is enshrined in such standard publications as those of I. E. S. Edwards,6 Rainer Stadelmann7 and Mark Lehner.8 Such partiality is instructive.

A statistical method for evaluating the abundance and colonization density of the pine beetle (Tomicus piniperda L.) on trap trees in Poland

The paper presents a statistical method for evaluating the abundance and colonization density of the pine beetle on trap trees. There was found a distinct linear correlation between the number of pine beetle galleries on 10% of the trap length from a butt and the number of galleries and colonization density over the whole trap.

Life History and Ecology of Plagithmysus bilineatus,1 an Endemic Hawaiian Borer Associated with Ohia Lehua (Myrtaceae)2

Host selection-oviposition by Plagithmysus bilineatus Sharp on its single host, Metrosideros collina (Forst.) Gray polymorpha (Gaud.) Rock, was a response to damaged or stressed hosts. Larval survival was not significantly higher in stressed hosts, but the number of galleries per host increased as the vigor (crown foliage condition) of the host decreased. Of 34 larvae implanted in healthy hosts, only four completed development; however, initial decline symptoms in these hosts did not appear until 10 to 22 months after adult emergence. Artificially girdled trees were monitored for 3 years, by which time four girdled trees had died, three being heavily attacked by P. bilineatus and one by ambrosia beetles. Harley diet with Bacto-Peptone supplement was tested as a culture medium for P. bilineatus larvae, with moderate (66%) success. The ecological functions of P. bilineatus were considered relative to the extensive decline of hosts in rain forests on the island of Hawaii.

PROLONGED INHIBITION OF BROOD PRODUCTION IN DENDROCTONUS RUFIPENNIS (COLEOPTERA: SCOLYTIDAE) BY DIMILIN

AbstractPre-attack feeding for 48 h on a diet containing 200 ppm Dimilin® (diflubenzuron), by adult Dendroctonus rufipennis (Kirby) (Coleoptera: Scolytidae), caused a complete inhibition of larval eclosion from eggs deposited by such beetles in the untreated host logs for the duration of the reproductive cycle. Inhibition of larval eclosion was mediated through the females only. Pre-attack application of 1% Dimilin to host logs reduced the number of larvae per gallery by 55% and reduced the number of galleries with successful larval eclosion by 42%.
