“…Data modelling for a different Lepidoptera species (Spodoptera frugiperda; Noctuidae) suggest that oviposition preference for Bt over non-Bt plants will significantly affect the speed of resistance evolution to the Bt trait [8]. This should be taken into account when designing the resistance management plan for Bt rice in China, especially because C. suppressalis can have up to five generations per year [47]. rspb.royalsocietypublishing.org Proc.…”

The area planted with insect-resistant genetically engineered crops expressing Bacillus thuringiensis (Bt) genes has greatly increased in many areas of the world. Given the nearby presence of non-Bt crops (including those planted as refuges) and non-crop habitats, pests targeted by the Bt trait have a choice between Bt and non-Bt crops or weeds, and their host preference may greatly affect insect management and management of pest resistance to Bt proteins. In this study, we examined the oviposition preference of the target pest of Bt rice, Chilo suppressalis, for Bt versus non-Bt rice plants as influenced by previous damage caused by C. suppressalis larvae. The results showed that C. suppressalis females had no oviposition preference for undamaged Bt or non-Bt plants but were repelled by conspecific-damaged plants whether Bt or non-Bt. Consequently, C. suppressalis egg masses were more numerous on Bt plants than on neighbouring non-Bt plants both in greenhouse and in field experiments due to the significantly greater caterpillar damage on non-Bt plants. We also found evidence of poorer performance of C. suppressalis larvae on conspecific-damaged rice plants when compared with undamaged plants. GC-MS analyses showed that larval damage induced the release of volatiles that repelled mated C. suppressalis females in wind tunnel experiments. These findings suggest that Bt rice could act as a dead-end trap crop for C. suppressalis and thereby protect adjacent non-Bt rice plants. The results also indicate that the oviposition behaviour of target pest females should be considered in the development of Bt resistance management strategies.

“…The arthropod sampling was carried out in the morning from 06.00 a.m. to 08.00 a.m. The obtained arthropods were put into vials containing 96% ethanol, labeled with the location and date of sampling then taken to the Entomology Laboratory of the Department of Plant Pests and Diseases, Faculty of Agriculture, Universita Sriwijaya to be identified morphologically using books written by Heinrichs et al (2017), and Whyte and Anderson (2017) and the number of individuals of each species from each survey location was recorded. The identification of arthropods was carried out by Dr. Chandra Irsan, an insect taxonomist of Universitas Sriwijaya.…”

Abstract. Herlinda S, Tricahyati T, Irsan C, Karenina T, Hasbi, Suparman, Lakitan B, Anggraini E, Arsi. 2021. Arboreal arthropod assemblages in chili pepper with different mulches and pest managements in freshwater swamps of South Sumatra, Indonesia. Biodiversitas 22: 3057-3066. In the center of freshwater swamps in South Sumatra, three different chili cultivation practices are generally found, namely differences in mulch and pest management that can affect arthropod assemblages. The effect of mulches and pest management on arboreal arthropod assemblages specific to chili production centers in the freshwater swamps of South Sumatra has never been investigated. This study aimed to observe arboreal arthropod assemblages in chili with different mulches and pest management. Arboreal arthropods were sampled using sweep nets in three locations with plots treated with leaf litter mulch and bioinsecticide, plastic mulch and synthetic insecticide, and weedy plot without mulch with synthetic insecticide. The species number of arboreal arthropods found was 28 species of Arachnids and 23 species of Insects, and consisting of 6 families of the Arachnids and 25 families of Insects. The abundance of arboreal arthropods was 65.60 individuals/5 nets per observation. In the chili field without mulch but with the insecticide, the species biodiversity and abundance of arboreal predatory arthropods were the highest. In contrast, in the chili field, that applied with synthetic insecticides and plastic mulch, the abundance of arboreal predatory arthropods was the lowest. The herbivorous insect populations in chili with plastic mulch and synthetic insecticides and the chili with the leaf litter mulch were higher than those in the chili without mulch. In the chili with the leaf litter mulch and bioinsecticide, the species number and abundance of the spiders were the highest compared to the other chili fields. The weedy chili field without mulch and chili with the leaf litter mulch has proved ideal habitats for the arboreal predatory arthropods.

“…Rice (Oryza sativa L.) is one of the world's most important grain crop, providing staple food for nearly half of the global population (Heinrichs et al, 2017). Bangladesh with its topography, fertile soil, abundant water and subtropical climate constitutes a favorable environment for the rice plant (Morshed et al, 2020).…”

“…The rice crop can be attacked by more than 100 species of insects and 20 of them can cause serious economic loss (Heinrichs et al, 2017). In Bangladesh, 175 species of insect pests have been recorded on rice (Mustafiz et al, 2007).…”

In the present study, some new generation insecticides were evaluated against rice leaf folder (RFL) infestation and their toxic effects were also observed on some natural enemies in the rice ecosystem. Data were collected on percent hill infestation, percent leaf infestation, number of moths/sweep, grain yield (t/ha) and abundances of natural enemies/m2. Results clearly showed that Serput (Bifenthrin) 2.5EC @ 2.0 ml/L water resulted in the greatest reduction of RFL and increased the grain yield compared to the untreated control which was followed by Envoy (Fipronil) 50SC @ 1.0 ml/L, Libsen (Spinosad) 45SC @ 0.40 ml/L, Acemida (Acephate + Imidacloprid) 51.8WDG @ 1.0 g/L, Suspend (Emamectin benzoate) 5SG @ 1.0 g/L, Combi-DT (Deltamethrin + Triazophos) 36EC @ 0.50 ml/L and Altima plus (Thiamethoxam + Emamectin benzoate) 40WG @ 0.20 g/L respectively. To know the toxic effect of selected insecticides, abundances (number/m2) of some natural enemies were counted at 7 days after given each spray. It was found that the highest numbers of natural enemies (m2) were recorded in the untreated control plot. In all field trials, the harmful effects of the seven insecticides were in the following rank order (least harmful to most harmful): Suspend 5SG, Serput 2.5EC, Envoy 50SC, Libsen 45SC, Acemida 51.8WDG, Altima plus 40WG and Combi-DT 36EC. Based on the reduction in rice leaf folder infestation, increase in grain yield and compatibility with natural enemies, Serput 2.5EC @ 2.0 ml/L proved to be the best among all the selected insecticides.
