Ethology of Sunn-pest oviposition in interaction with deltamethrin loaded on mesoporous silica nanoparticles as a nanopesticide

Abstract Background Wheat is one of the main food for around 2 billion people worldwide. Among biological stressors, Eurygaster integriceps Puton a damaging insect in wheat and barley fields, which harms them both quantitatively (by overwintered adults) qualitatively instar nymphs). The ovipositional new generation’s production control are pivotal approaches to severe damages Sunn-pest. Methods In this study, enhance deltamethrin effectiveness while reducing its required dosage also adverse health environmental impacts, novel MSN-based formulation was prepared evaluated based on laying-eggs number oviposition behavior. To this, loaded KIT-6 mesoporous silica nanoparticles characterized using SEM, TEM, TGA analysis, potential deltametrin@KIT6 then evaluated. Results results showed that there might be differences between treatments (KIT-6, deltamethrin@KIT-6, commercial formulation, water as control) terms via laying-egg next-generation prevention. deltamethrin@KIT-6 could reduce rate compared control. Deltamethrin@KIT-6 not only caused less done but eggs were scattered batch did have uniform-shape similar mode. nanopesticide increase pesticide by Sunn-pest’s nymphal population subsequently decreasing damage them. So concentrations 10, 25, 125 mg L −1 reduced 63.24%, 66.11%, 67.62%, respectively, group. On other hand, descriptive observations another possible tension created through deposition boundary layer leaves. Conclusion nanoformulation effectively considered density Graphical
