Summary: Accumulating evidence suggests that herbivorous insects influence the local composition and richness of Neotropical plant species, particularly in species-rich genera. Species richness, phylogenetic diversity, and chemical diversity all influence the ability of insect herbivores to find and utilize their hosts.

Summary: This study identified the ABC transporter gene PxABCG20 from diamondback moth, showing differential expression in Cry1Ac-resistant and susceptible strains, and found that RNAi knockdown of PxABCG20 increased tolerance to Cry1Ac protoxin. Furthermore, miRNA novel-miR-310 was discovered to regulate PxABCG20 expression, affecting the susceptibility of insects to Cry1Ac toxin.

Summary: Circadian clocks, controlled by the period gene, regulate many behavioral and physiological rhythms in the moth Plutella xylostella. Loss of the period gene disrupts locomotor activity rhythms, affects pupal eclosion, mating, egg-laying, and egg hatching, and alters molecular and transcription rhythms in the heads of the moths.

Summary: This study identified 15 putative chorion gene sequences in the diamondback moth, Plutella xylostella, and found that these genes are highly specifically expressed in the ovaries of adult females, with significant effects on egg size and hatchability.

Summary: This study identified a correlation between the D472N mutation in the Rdl1 GABAR gene and abamectin resistance in Plutella xylostella. A knock-in homozygous mutation strain with the D472N mutation was successfully constructed, showing significantly increased resistance to abamectin and endosulfan. However, there was no change in resistance to other insecticides. Additionally, the D472N mutation strain exhibited reduced fecundity.

Summary: In this study, two paralogous antennae-enriched CCEs from Plutella xylostella were identified and functionally characterized, with one enzyme (PxylCCE16c) showing a more essential role in odorant degradation and potential as a novel pesticide target for the notorious moth Plutella xylostella.

Summary: The diamondback moth (DBM) has adapted to the chemical defenses of Brassicaceae plants, but its role in the DBM's adaptation to plant defense compounds is unknown. In this study, the secondary metabolites of radish seedlings were identified and found to reduce the growth of DBM larvae lacking gut bacteria. However, the re-introduction of Enterobacter dominated gut microbiota counteracted this effect. The bacterium Enterobacter not only degrades the flavonoid kaempferol, but also colonizes the gut epithelium, forming a protective biofilm.

Summary: The study identified the GSTu1 gene and its antisense transcript lnc-GSTu1-AS as key players in the resistance of Plutella xylostella to chlorantraniliprole, revealing a new noncoding RNA-mediated pathway that regulates the expression of detoxifying enzymes in insecticide-resistant insects. The research sheds light on the mechanisms of insecticide resistance and offers new opportunities for further understanding drug resistance.

Summary: Plant-herbivore interactions play a crucial role in the biodiversity of ecosystems. This study investigates the defensive strategies employed by swamp white oak against insects and large mammals. The results show that plant defense strategies vary spatially on individual trees, and the presence of different herbivores can affect the composition of plant defenses.

Summary: Late season mowing may not be sustainable for conserving plant diversity in salt marshes, while other management regimes can maintain plant diversity across spatial scales and vegetation heterogeneity at the larger scale in the long term. However, local community composition may change over time under these regimes.

Summary: The mass rearing of insects as animal feed in circular agriculture has great potential for promoting insect health and welfare. This review focuses on the behavioural knowledge of the black soldier fly and the housefly, two commonly used species. It examines their feeding behaviour, social interactions, oviposition behaviour, and the influence of abiotic factors and microbiome on their behaviour. The review identifies important behavioural differences between the two species and highlights the implications for mass rearing conditions. Recommendations for future research to improve insect welfare are provided.

Summary: Due to increasing restrictions on insecticide use, reliable options to control cabbage root fly are lacking. This study suggests amending soil with residual streams from insect production as an alternative to synthetic fertilization for microbial crop protection. Experimental results show that amending soil with black soldier fly residual streams can effectively reduce cabbage root fly survival and biomass, while residual streams from house crickets and mealworms do not negatively affect root fly performance.

Summary: Soil composition and herbivory can affect plant traits, including flower traits, potentially influencing plant-pollinator interactions. We investigated the effects of insect exuviae as soil amendment and aboveground insect herbivory on Brassica nigra plants. Our findings showed that soil amendment increased flower quantity and volatile organic compound (VOC) emission, while herbivory reduced petal area and VOC emission. Furthermore, soil amendment and herbivory interacted in their effect on petal reflectance spectrum and VOC emission.

Summary: In response to herbivory, most plant species adjust their chemical and morphological phenotype to acquire induced resistance to the attacking herbivore. Induced resistance offers strong potential to enhance resistance and resilience of crops to (multi-) herbivore attack by promoting plant plasticity, attracting natural enemies, and enhancing associational resistance. It may prove to be an invaluable trait in breeding for crop resilience in more sustainable ecology-based cropping systems.

Summary: This study compared the chemosensory genes of two Pieris butterflies and found that the differences between them might be more related to a quantitative shift in gene expression rather than the evolution of novel receptors. The results provide molecular data to better understand the role of chemoreceptor genes in the evolution of lepidopterans.

Summary: Microorganisms living in and on macroorganisms can produce volatile compounds that can help carnivorous enemies locate their host or prey. Parasitism by parasitoid wasps can alter the microbiome and odour of their caterpillar host, which can affect interactions with other insects. This study analyzed the odours and microbiome of cabbage white caterpillars in relation to parasitism by endoparasitoid wasps and found that parasitism led to the production of characteristic volatile compounds and significant changes in the caterpillar's microbiome. The preference of a hyperparasitoid was correlated with the presence of the external microbiome.

Summary: In this study, the researchers examine the impact of social contexts, specifically group discussions, on farmers' decision-making process regarding the adoption of sustainable innovations in crop and soil health management, focusing on the use of insect by-products called "frass". It is found that farmers engaging in group discussions consider a wider range of attributes such as price, ease of use, and environmental impact, while those not involved focus more on specific product characteristics like nutrient content and organic matter. This distinction emphasizes the importance of social interaction in expanding awareness and understanding, providing deeper insights into the factors influencing adoption decisions in agriculture.

Summary: This study assesses the aphid species present in Dutch strawberry crops, the facultative endosymbionts they carry, and how these endosymbionts affect the parasitism success of biocontrol parasitoid wasps. The results show that facultative endosymbiont infections can protect aphids against certain parasitoids, but the level of protection varies among aphid species and parasitoid species.
