Thiamethoxam-Induced Intergenerational Sublethal Effects on the Life History and Feeding Behavior of Rhopalosiphum padi.

ABSTRACT: Thiamethoxam, a second-generation neonicotinoid insecticide is widely used for controlling sap-sucking insect pests including Rhopalosiphum padi. The current study aimed to investigate the life-history parameters and feeding behavior of R. padi following treatments with sublethal concentrations of thiamethoxam. The lethal concentration 50 (LC₅₀) value of thiamethoxam against adult R. padi was 11.458 mg L^-1 after 48 h exposure. The sublethal concentrations of thiamethoxam (LC₅ and LC₁₀) significantly decreased the adult longevity, fecundity, and reproductive days in the directly exposed aphids (F₀ generation). In the progeny R. padi (F₁), the developmental durations and total prereproductive period
