Toxicity evaluation of different chemical pesticides against Riptortus pedestris (Hemiptera: Alydidae) under laboratory condition in Bangladesh

The Lethal and Sublethal Effects of Lambda-Cyhalothrin and Emamectin Benzoate on the Soybean Pest Riptortus pedestris (Fabricius)

“…In this study, the LC 50 value of LCT following the exposure of third instar R. pedestris nymphs for 72 h was 2.68 mg/L, consistent with its pronounced toxicity. The cypermethrin has similarly been shown to exhibit a high degree of toxicity against this pest species [ 37 ]. The LC 50 value of EMB (7.68 mg/L) was 1.87-fold higher than that of LCT, potentially owing to the fact that these insecticides exhibit different modes of action.…”

“…Insecticides remain an essential component of IPM strategies as they can rapidly and effectively mitigate the harm associated with a broad range of pest species [35,36]. In agroecosystems, however, these pesticides are subject to asymmetrical application and degradation such that insects are frequently exposed to sublethal concentrations of these chemicals [37]. At sublethal concentrations, these compounds can still have profound effects on the biology, physiology, and biochemistry of exposed pests, thereby modulating overall population dynamics [7,12].…”

Hadronotus pubescens (Motschoulsky) (Hymenoptera, Scelionidae): Redescription, biological attributes, and parasitism on eggs of Riptortus pedestris (Fab.) (Hemiptera, Alydidae)

“…Riptortus pedestris (Fab.) (Hemiptera, Alydidae) is a destructive pest on a wide range of crop plants in Korea and Japan (Honda 1986;Son et al 2000;Kang et al 2003;Lee et al 2004) and has infested many leguminous crops in Bangladesh (Arifunnahar et al 2019(Arifunnahar et al , 2021. It is also an important hemipteran pest of soybean (Glycine max (L.) Merr.)…”
