Abstract The fall armyworm (FAW), Spodoptera frugiperda , is a highly polyphagous invasive pest that damages on various crops. Pesticide control the most common and effective strategy to of FAW. In this study, we evaluated toxicity metaflumizone indoxacarb against third-instar FAW larvae using insecticide-incorporated artificial diet method under laboratory conditions. Both exhibited substantial FAW, with LC 50 values 2.43 14.66 mg/kg at 72 h, respectively. sublethal effects were investigated by exposing 10 30 concentrations these insecticides. Sublethal exposure two insecticides significantly shortened larval adult developmental times, extended pupal led reduced weight, pupation rates, fecundity in treated parental generation or concentrations, comparison group. We also assessed he transgenerational effects, findings indicated had comparable F0 generation, except for an observed significant increase time F1 generation. Furthermore, Larvae exposed elevated activity levels Multifunctional oxidase (MFO) glutathione S-transferase (GST), which coincides synergistic effect PBO DEM. conclusion, high negative impact provided implications rational utilization pest.

Synthetic insecticides have been an inevitable part of plant protection throughout the world. Sublethal effects these chemicals on beneficial insect species are one contemporary issues days. Using age-stage, two-sex life table model, this study evaluated sublethal and transgenerational six synthetic (imidacloprid, thiamethoxam, lambda-cyhalothrin, cypermethrin, chlorpyrifos profenofos) commonly applied to winter vegetables, fitness predation seven-spotted ladybeetle, Coccinella septempunctata, which is efficient predator aphids worldwide. According results, all at their doses (LC30) significantly suppressed emergence adults, adult weight, fertility fecundity parental generation compared control treatment. The larval stage was prolonged oviposition, total longevity beetles were decreased in unexposed progeny whose parents exposed insecticides. Moreover, biological parameters including intrinsic rate increase (r), finite (λ) net reproductive (R0) reduced when F1 adults also after exposure However, chlorpyrifos, profenofos, lambda-cyhalothrin cypermethrin exhibited more deleterious population than imidacloprid thiamethoxam.

Spodoptera frugiperda (J. E. Smith), commonly known as the fall armyworm (FAW), causes significant damage to many different crop species. In this study, age-stage, two-sex life table analysis was used investigate effects of sublethal concentrations emamectin benzoate and chlorantraniliprole on FAW development reproduction. F0 generation, exposure significantly impacted duration FAW, thus prolonging each instar, but not prepupal stage. Furthermore, weight pupae reduced by at LC25 in generation. With respect fecundity, fecundity F1 LC10 had no effect preadult or adult stages, whereas shortened period. The stages exposed were prolonged. pupal Chlorantraniliprole LC10, occurred Interestingly, increased which could promote population growth pest resurgence. These findings have important implications for integrated management provide a reference more effective control FAW.

For decades, various agrochemicals have been successfully repurposed for mosquito control. However, preexisting resistance caused in larval and adult populations by unintentional pesticide exposure or other cross-resistance mechanisms poses a challenge to the efficacy of this strategy. A better understanding adaptation lethal sublethal effects residual pesticides aquatic habitats would provide vital information assessing against mosquitoes. We reared field-collected larvae water containing concentration agrochemical causing 100% mortality susceptible mosquitoes after 24 h (lethal concentration). Using experimental setup, we tested effect concentrations pyrrole (chlorfenapyr, 0.10 mg/l), pyrethroid (deltamethrin, 1.5 three neonicotinoids including imidacloprid (0.075 acetamiprid (0.15 clothianidin (0.035 mg/l) on rates, growth, survival third-instar two sibling species Anopheles gambiae coluzzii collected from Yaoundé, Cameroon. found that An. were chlorfenapyr killed within nominal mg/l. Consistent with strong resistance, deltamethrin induced low both species. Lethal acetamiprid, imidacloprid, strongly inhibited survival, emergence larvae. By contrast, depending active ingredient population tested, 5-60% immature stages able grow emerge neonicotinoids, suggesting class insecticides. These findings corroborate susceptibility profiles observed adults suggest processes could contribute development some populations.

Abstract Methoxyfenozide is an insecticide with a unique mode of action on the insect ecdysone receptor and has been registered for control pests all over world. In present work, Spodoptera frugiperda was exposed to sublethal lethal concentrations methoxyfenozide determine its impact specific biological traits, metabolic enzyme activity, expression detoxification enzymes. The result showed that 72-h posttreatment LC50 LC70 significantly reduced fecundity (eggs/female) F0 generation compared those group. However, duration prepupal period increased. exposure LC10, LC30, LC50, extended developmental larvae in F1 individuals. decreased, population life table parameters were also affected. activity carboxylesterases little significant change, whereas glutathione S-transferases (GSTs) cytochrome P450 monooxygenases (P450s) altered after methoxyfenozide. total, 24-, 48-, 96-h could cause upregulation genes such as CYP6AE44, CYP6B39, CYP9A26, CYP9A58, CYP9A59, CYP9A60, well GST including GSTe3, GSTe9, GSTe10, GSTe15, GSTo2, GSTs1, GSTs5, GSTm2, GSTm3. These findings be instrumental elucidating molecular mechanisms underlying effects S. frugiperda.
