Abstract Allium mongolicum Regel leaf beetle, Galeruca daurica (Coleoptera: Chrysomelidae) is rampantly harmful in Inner Mongolia grassland. However, the current management strategies for this pest still heavily rely on chemical control using traditional insecticides or those with novel action. In study, we conducted an indoor bioassay to evaluate sublethal effects of chlorantraniliprole biological characteristics. Additionally, assessed activity detoxification enzymes, specifically primary enzymes carboxylesterase (CarE) and cytochrome P450, insect's secondary metabolic namely glutathione S‐transferase (GST) uridine diphosphate glycosyltransferase (UGT), as well its gene expression profile. The developmental period 3rd instar larvae G. was significantly prolonged after treatment chlorantraniliprole, which negatively affected hatching, pupation diapause rates their body weight. showed different dynamics enzyme activities within 24 h treatment. Different concentrations inducing effect activities, while no significant difference observed P450. Expression profiling detoxifying genes screened by transcriptome data has revealed that 6 CarE, 2 GST, 7 UGT 31 P450 were up‐regulated. conclusion, chlorantraniliprole's resulted a deceleration growth processes increased levels GST UGT. proteins encoded up‐regulation may involve metabolism chlorantraniliprole. Our results provide basis understanding molecular mechanisms action key grassland insect pest.

Fall armyworm [Spodoptera frugiperda (J. E. Smith, 1797)] was first reported in the Americas, then spread to all continents of world. Chemical insecticides are frequently employed managing fall armyworms. These have various modes actions and target sites kill insects. Chlorantraniliprole is a selective insecticide with novel mode action used against Lepidopteran, Coleopteran, Isopteran, Dipteran pests. This study determined chlorantraniliprole’s lethal, sub-lethal, trans-generational effects on two consecutive generations (F0, F1, F2) armyworm. Bioassays revealed that chlorantraniliprole exhibited higher toxicity armyworms LC50 2.781 mg/L after 48 h exposure. Significant differences were noted biological parameters generations. Sub-lethal concentrations showed prolonged larval adult durations. The related fitness cost F0 F1 non-significant differences. In contrast, F2 generation lower fecundity at lethal (71 eggs/female) sub-lethal (94 doses compared control (127.5–129.3 eggs/female). Age-stage specific survival rate (Sxj), life expectancy (Exj) reproductive (Vxj) significantly differed among insecticide-treated groups control. A comparison treated untreated insects over indicated substantial demographic such as net reproduction (R0), intrinsic increase (r), mean time (T). Several shown be negatively impacted by chlorantraniliprole. We conclude may utilized manage lesser risks.

λ-Cyhalothrin (λ-cyh) is widely used in agricultural production and has been reported to cause damages numerous nontarget insects. As an important economic model insect of Lepidoptera, Bombyx mori was extremely sensitive λ-cyh, pesticide drift often leads silkworm poisoning. However, little known about the persistence sublethal effects or potential recovery from short-term exposure doses pesticides. In this study, we estimated caused by (24 h) λ-cyh LC1 , LC10 LC25 LC50 respectively, investigated persistent negative on growth, survival, pupal metamorphosis larvae.

The integrated use of plant-derived volatile attractants and synthetic insecticides in attract-and-kill programs is a useful tool for pest management reducing pesticide input. Efficient alternative are critically needed to replace methomyl, which has been banned on cruciferous vegetables China because it also highly toxic nontarget organisms. In the present study, among 15 commonly used were screened toxicity against S. litura moths, where chlorantraniliprole, flubendiamide, emamectin benzoate was found have highest levels (LC50 0.56, 3.85, 6.03 mg a.i. L−1 respectively). After exposure low lethal concentration LC50 fecundity moths substantially reduced. Egg-hatching lower LC20- LC50-treated moth pairs than untreated control pairs. Net reproductive rate (R0), intrinsic increase (r), finite (λ) significantly reduced LC50♀ × LC50♂ cohorts. Larval mortality higher subsequent generations moths. Chlorantraniliprole, most had significant sublethal effects can be as an insecticide methomyl attracticide controlling indicated high potential efficacy through schemes.

Abstract BACKGROUND Agrotis ipsilon and A. segetum are major migratory pests of many crops in China, frequent regional outbreaks cause severe yield losses. Use food attractants is one the most promising control methods against adult lepidoptera, notably through attract‐and‐kill strategy. Chlorantraniliprole's acute toxicity sublethal effects on both moths were evaluated.

Low-lethal concentrations insecticides may affect not only survival rate but also demographic parameters a pest. To understand effect low-lethal S. frugiperda, developmental after treatment by three different modes action pesticides tetrachloroamide, spinetoram, and lufenuron were analyzed. For F0 generation, pupal length weight FAW insecticide significantly longer heavier than that control. F1 adult longevity egg hatching spinetoram treated was shorter lower While no significant observed for intrinsic increase (r), finite (λ), mean generation time (T) net reproductive (R0) decreased treatment. Results showed negatively larval rate, caused early maturity, treatments increased reproduction.
