Nanobiotechnology is among the emerging fields and its applications in agriculture are attracting the scientific community. In this study, the influence of neem oil encapsulated chitosan nanoparticles (NO-ChNPs) on the feeding, growth and reproductive performances of polyphagous insect pest Helicoverpa armigera in the cotton ecosystem was evaluated. The nanoparticles treated insects showed growth deformities with extended larval and pupal durations and reduced fecundity and it may be due to the hormonal impact on the growth and reproduction. The treatment with nanoparticles considerably affected the feeding performances on the amount of food consumed and efficiency of conversion of ingested and digested food values. There was strong evidence from the experimental results that the decreasing trend of digestive enzymes and lesser faecal pellet egestion, which implies that the nanoparticles bind the gut receptors and hindered the feeding regulations of insect species. The parasitisation (larval parasitoid, (Campoletischlorideae) of as well as the survival of the earthworm (Eudriluseugeniae) population does not affected by neem oil encapsulated nanomaterials. Hence, these formulations can be used for the integrated management of Helicoverpa armigera in the agro-ecosystem. Overall, this research highlights the potential of NO-ChNPs for the development of newer control tools against control of cotton bollworm; also highlighting some risks concerned the employ of nanoparticles in aquatic/terrestrial environments.
