ABSTRACT Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a major insect pest that responsible for huge economic losses to maize crops. The study on the sublethal effect of insecticide S. crucial its comprehensive management in field. Thus, current evaluated effects Voliam Flexi, which combination thiamethoxam and chlorantraniliprole, demographic parameters exposed LC 10 , 20 30 concentrations. results indicated larvae showed longer period (35.4 days at 37.9 39.5 ) compared those control group (30.4 days). fecundity rate was also reduced when concentrations were applied (298.1 eggs 253.2 214.1 (339.3 eggs). doses exhibited significant decrease intrinsic increase ( r ), net reproduction R 0 finite λ group. These findings suggest Flexi adversely affect growth reproductive capacity ultimately aiming keep populations below levels cause damage. Our highlight potential effective implementation IPM plan field against .

Trehalases (TREs), serving as crucial enzymes regulating trehalose and chitin metabolism in insects, represent prime targets for pest control strategies. We investigated the impact of three thioxothiazolidin compounds (1G, 2G, 11G) on TRE activity summarized their effects growth development Spodoptera frugiperda (Lepidoptera, Noctuidae). The experimental larvae S. were injected with 11G), while group received an equivalent volume 2% DMSO a control. All had strong effect inhibiting activity, significantly prolonging pre-pupal stage. However, compared 11G-treated group, survival rate treated 1G 2G was reduced by 31.11% 27.78% respectively, occurrence phenotypic abnormalities related to higher. These results manifest that only inhibitors, modulate pathways larvae, ultimately resulting failure molting reduction rates. Consequently, compounds, hold potential environmentally friendly insecticides.

Abstract BACKGROUND Lepidopteran pest control in agriculture has become heavily dependent on cultivars that express Bacillus thuringiensis ( Bt ) toxins as ‘plant‐incorporated protectants’. However, populations of Spodoptera frugiperda (Smith) Brazil appear resistant to the traits currently available commercial soybean cultivars. RESULTS This study evaluated S. life history when feeding three different Cultivars expressing Cry1Ac + Cry1F and Cry1A.105 Cry2Ab2 caused 100% larval mortality . Both non‐Bt Cry1Ac‐expressing induced transgenerational effects increased survival subsequent generations. A diet reduced generation time (T) relative soybean, resulting shorter more rapid population growth. CONCLUSION The implications these results revealed how can alter aspects insect biology, have important for sustainable management soybean. © 2024 Society Chemical Industry.
