“…It is assumed that reduced fecundity in response to insecticide exposures may result in suppression of the subsequent generation of the insect pest population. 37,76 The results of the current study regarding reduced fecundity and prolonged developmental period after exposure of M. domestica to ZnO-Bti-supernatant nanoparticles are in agreement with a previous study 18 reporting reduced fecundity and prolonged larval, pupal and total developmental duration of C. maculatus after exposure to ZnO-Bti-supernatant nanoparticles.…”

BACKGROUND Indiscriminate use of broad‐spectrum insecticides can have deleterious effects on insects and the environment. The use of nanoparticles synthesized from microbes has recently gained importance as a safe alternative to conventional insecticides. Recently, zinc oxide (ZnO) nanoparticles synthesized using Bacillus thuringiensis have shown insecticidal potential; however, in addition to its acute toxicity, it is necessary to determine possible sublethal effects at the organismal level to understand the toxicity of a new insecticide. Bt‐derived enzymes such as nitrate reductase and other biomolecules play a vital role in the reduction of metal ions to metal nanoparticles. Here, we assessed the acute toxicity and sublethal effects of ZnO nanoparticles produced in the culture supernatant of B. thuringiensis ser. israelensis (Bti) as a reducing agent on the biological traits of Musca domestica. RESULTS Concentration–response larval bioassays using different concentrations of ZnO‐Bti‐supernatant nanoparticles revealed LC10, LC20, LC50 and LC90 values of 4.17, 6.11, 12.73 and 38.90 μg g−1 of larval diet, respectively. Exposure of M. domestica larvae to two concentrations (LC10 and LC20) resulted in a lengthened developmental time (egg to adult) and preoviposition period, and reduced fecundity, survival, longevity and oviposition period. Furthermore, population parameters including net reproductive rate, mean generation time, age‐specific survival rate, fecundity, life expectancy and reproductive values, analyzed following age‐stage and two‐sex life table theory, were significantly decreased after exposure to these concentrations of ZnO‐Bti‐supernatant nanoparticles compared with the control. CONCLUSION ZnO‐Bti‐supernatant nanoparticles were shown to be toxic to M. domestica. Exposure of M. domestica to low concentrations of ZnO‐Bti‐supernatant nanoparticles resulted in negative transgenerational effects on progeny production in this fly. © 2022 Society of Chemical Industry.

“…In the field, soybean aphids are usually exposed to insecticides at low-lethal or sublethal concentrations [ 39 ]. Subsequent generations of soybean aphids have developed low-level resistance to insecticides through the accumulation of mutations, leading to gradual increases in the extent of their resistance and eventual resurgence of soybean aphid populations [ 40 ].…”

Effects of imidacloprid and thiamethoxam on the development and reproduction of the soybean aphid Aphis glycines

The soybean aphid Aphis glycines Matsumura (Hemiptera: Aphididae) is a primary pest of soybeans and poses a serious threat to soybean production. Our studies were conducted to understand the effects of different concentrations of insecticides (imidacloprid and thiamethoxam) on A. glycines and provided critical information for its effective management. Here, we found that the mean generation time and adult and total pre-nymphiposition periods of the LC50 imidacloprid- and thiamethoxam-treatment groups were significantly longer than those of the control group, although the adult pre-nymphiposition period in LC30 imidacloprid and thiamethoxam treatment groups was significantly shorter than that of the control group. Additionally, the mean fecundity per female adult, net reproductive rate, intrinsic rate of increase, and finite rate of increase of the LC30 imidacloprid-treatment group were significantly lower than those of the control group and higher than those of the LC50 imidacloprid-treatment group (P < 0.05). Moreover, both insecticides exerted stress effects on A. glycines, and specimens treated with the two insecticides at the LC50 showed a significant decrease in their growth rates relative to those treated with the insecticides at LC30. These results provide a reference for exploring the effects of imidacloprid and thiamethoxam on A. glycines population dynamics in the field and offer insight to agricultural producers on the potential of low-lethal concentrations of insecticides to stimulate insect reproduction during insecticide application.

“…The root application was applied to examine the bioactivity of imidaclothiz/SPc complex toward green peach aphids that pierce the phloem and indirectly transmit plant virus in many crops [ 62 ]. Similar to the methods described by Deng et al [ 63 ] and Zhang et al [ 64 ], the roots of 9–10 cm height radish seedlings infested with aphids (about 30 aphids per plant) were immersed in the formulations of imidaclothiz and imidaclothiz/SPc complex. The highest concentrations of SPc and ddH 2 O were employed as controls.…”

There is a great demand for improving the effective utilization of pesticides and reducing their application for sustainable agriculture, and polymeric nanoparticles have provided strong technical support for the efficient delivery of pesticides. To this context, we tried to construct a relatively safe imidaclothiz nano-delivery system for enhanced plant uptake, reduced pesticide residue and improved bioactivity toward green peach aphids. The imidaclothiz could be assembled with the hydrophobic core of SPc through hydrophobic association, which led to the self-assembly of nanoscale imidaclothiz/SPc complex consisting of nearly spherical particles. The SPc decreased the contact angle of imidaclothiz drops and remarkably increased the plant uptake. Furthermore, the bioactivity and control efficacy of imidaclothiz were significantly improved with the help of SPc in both laboratory and field. Excitingly, the residue of imidaclothiz decreased with the help of SPc 7 d after the treatment due to the faster degradation of nanoscale imidaclothiz/SPc complex, which exhibited no negative effects on agronomic traits of tobacco plants. The current study successfully constructed a nano-delivery system for imidaclothiz, which can not only increase the effective utilization of pesticides, but also decrease the pesticide residue.
