Spodoptera frugiperda is a major agricultural pest, and the 1st -3rd instar S. frugiperda have spinning behaviour and can drift to adjacent plants with the help of the wind. The present study found that azadirachtin can affect this behaviour, and the mechanism by which azadirachtin affects the spinning behaviour of S. frugiperda has been studied. In this study, the 3rd instar larvae were exposed to azadirachtin, and the pathological changes in the silk glands of S. frugiperda and the differences in their metabolites were analysed by pathological sectioning, transmission electron microscopy, metabolomics and other experimental methods. The results showed that azadirachtin can affect the silk gland of S. frugiperda. After 48 h of treatment with azadirachtin, the silk gland lumen of S. frugiperda appeared vacuolated, and KEGG showed that 31 different metabolites were identi ed, of which 12 were upregulated and 19 were downregulated. These metabolites were enriched in 15 different metabolic pathways, which pathways indicated that the silk gland of S. frugiperda was closely related to the formation of fatty acids and to energy metabolism in the process of silk formation. This research can further explain the spinning mechanism of insects and provide a research basis for determining the spinning, cocooning, and transfer damage mechanisms of many agricultural and forestry pests. Key MessageThe 1st -3rd instar Spodoptera frugiperda can spit and drift to neighbouring plants.Azadirachtin causes a decrease in the amino acids histidine, glycine, and leucine in the silk glands of Spodoptera frugiperda.Azadirachtin causes insect silk to break more easily.Feeding with azadirachtin for 72 h reduces Spodoptera frugiperda spinning.Azadirachtin can affect the development of the silk glands of Spodoptera frugiperda and thus affect silking behaviour.

“…In fact, the nitro group fixation in a cis configuration for different neonicotinoid types has yielded compounds with certain biologic functions and behaviors, supporting their potential efficiency to elucidate the pharmacology and characteristics of the neonicotinoid binding sites. Neonicotinoids consist of 5-membered ring derivatives, including imidacloprid and thiacloprid, 6-membered ring compounds, including thiamethoxam, and also noncyclic structures such as nitenpyram, acetamiprid 6 – 11 , clothianidin, and dinotefuran employed for a wide range of pests 12 – 14 . Organophosphates are becoming more and more common as pesticides across the world and have recently replaced organochlorine insecticide 15 .…”

Acetamiprid removal was investigated by synthesized Graphene oxide, multiwall nanotube and graphite from an aqueous solution. For this propose, FT-IR, XRD, UV–Vis, SEM and EDS were used to characterize the synthesized nano adsorbents and to determine the removal process. A novel PVC membrane electrode as selective electrode made for determining the concentration of acetamiprid. Batch adsorption studies were conducted to investigate the effect of temperature, initial acetamiprid concentration, adsorbent type and contact time as important adsorption parameters. The maximum equilibrium time was found to be 15 min for graphene oxide. The kinetics studies showed that the adsorption of acetamiprid followed the pseudo-second-order kinetics mechnism. All the adsorption equilibrium data were well fitted to the Langmuir isotherm model and maximum monolayer adsorption capacity 99 percent. Docking data of adsorption have resulted in the same as experimental data in good manner and confirmed the adsorption process.

“…The neonicotinoids have quickly occupied the market because of their excellent efficacy on target pests and minimal toxicity to mammals (Shao et al, 2013; Xu et al, 2021). Among neonicotinoids, acetamiprid is widely used to control A. glycines on soybean, cotton, tobacco, and other crops (Aseperi et al, 2020; Lu et al, 2021; Mokbel, 2019). However, some insects were exposed to low or sublethal concentrations of acetamiprid following continuous degradation by plants, animals, fungi, and bacteria (Desneux et al, 2005; Fenner et al, 2013; Han et al, 2019).…”

“…The juvenile and molting hormones interacted and restricted each other in different development stages. The continuous synthesis and degradation of juvenile and molting hormones were crucial indicators for determining the reproductive capacity of populations exposed to insecticides (Mirth et al, 2014;Zhang et al, 2019). This study aimed to investigate the effects of acetamiprid on redox, energy metabolism, and hormone levels in soybean aphids under continuous exposure.…”

Aphis glycines Matsumura (Hemiptera: Aphididae) is a major soybean pest that often poses a serious threat to soybean production. In this study, we checked the effects of acetamiprid on redox, energy metabolism, and hormone expression in A. glycines. The LC 50 and LC 30 of acetamiprid were used to treat the fourth instar nymphs in each generation from F0 to F4 to measure the activity of peroxidase, pyruvate kinase, and trehalase using a microassays approach. The peroxidase activity was significantly higher than control when treated with the LC 30 of acetamiprid in F2−F5 generations. The activity of pyruvate kinase was significantly higher, while trehalase activity was substantially lower than control in each generation.Besides, we monitored molting and juvenile hormone expression in soybean aphids using enzyme-linked immunosorbent assay. The juvenile hormone titer of third instar nymphs was significantly higher in the treatment group (F1, F2, F4, and F5), while no effects were noted in the F3 generation. Taken together, the activity of peroxidase and pyruvate kinase in soybean aphid first increased to the peak and then decreased, while the trehalase activity continuously decreased in all generations following exposure to acetamiprid. The juvenile hormone titer was significantly higher, while the molting hormone titer was significantly lower in LC 50 -treated aphids than in control.
