“…The peritrophic membrane is thought to aid in digestion and protection from toxins [ 57 ]. Previous work has shown altered expression of peritrophin-like proteins linked to cycloxaprid application [ 58 ] and silencing peritrophins can lead to higher imidacloprid susceptibility in termites [ 59 ]. While it's unclear here why we observe reduced expression of pertriphonins in resistant individuals, it is possible that these genes have roles in resistance mechanisms through altered gut structure or detoxification.…”

Background Homalodisca vitripennis Germar, the glassy-winged sharpshooter, is an invasive insect in California and a critical threat to agriculture through its transmission of the plant pathogen, Xylella fastidiosa. Quarantine, broad-spectrum insecticides, and biological control have been used for population management of H. vitripennis since its invasion and subsequent proliferation throughout California. Recently wide-spread neonicotinoid resistance has been detected in populations of H. vitripennis in the southern portions of California’s Central Valley. In order to better understand potential mechanisms of H. vitripennis neonicotinoid resistance, we performed RNA sequencing on wild-caught insecticide-resistant and relatively susceptible sharpshooters to profile their transcriptome and population structure. Results We identified 81 differentially expressed genes with higher expression in resistant individuals. The significant largest differentially expressed candidate gene linked to resistance status was a cytochrome P450 gene with similarity to CYP6A9. Furthermore, we observed an over-enrichment of GO terms representing functions supportive of roles in resistance mechanisms (cytochrome P450s, M13 peptidases, and cuticle structural proteins). Finally, we saw no evidence of broad-scale population structure, perhaps due to H. vitripennis' relatively recent introduction to California or due to the relatively small geographic scale investigated here. Conclusions In this work, we characterized the transcriptome of insecticide-resistant and susceptible H. vitripennis and identified candidate genes that may be involved in resistance mechanisms for this species. Future work should seek to build on the transcriptome profiling performed here to confirm the role of the identified genes, particularly the cytochrome P450, in resistance in H. vitripennis. We hope this work helps aid future population management strategies for this and other species with growing insecticide resistance.

Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), has become the most destructive insect pest of Brassicaceae plants globally. Numerous control methods are available to control the moth, such as host plant resistance, physical controls, chemical controls, cultural controls, and biological controls. The continued application of insecticides has led to the development of resistance to almost 97 chemical compounds. The biological methods also became inefficient in the control of the moth. Therefore, nanotechnology would provide green and efficient alternatives for controlling the pest without harming environment. This review focuses on control methods used to manage diamondback moth and nanomaterials’ potential in insect pest management as modern nanotechnology approaches. It focuses on the past, present, and future scope of diamondback moth management
