The fall armyworm, Spodoptera frugiperda (Noctuidae: Lepidoptera), is a wide-reaching notorious insect pest of important cereal crops, which has developed resistance to multiple classes insecticides. It invaded the Sichuan Province China in 2019. In this study, we performed monitoring insecticides for 11 field-collected populations from Sichuan, and all were susceptible emamectin benzoate chlorpyrifos. variations level indoxacarb (resistance ratio (RR), 9.23-45.53-fold), spinetoram (RR,...
Abstract Behavioral studies play a crucial role in assessing food utilization insects. However, there exists gap our understanding of the phenotypic plasticity Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) and how it impacts their growth, development, potential for plant damage. This study aimed to investigate S. , with focus on its immature stages, evaluate consequences damage pest management. We conducted vitro experiments using both standard artificial diet tobacco ( Nicotiana...
The gray planthopper [Laodelphax striatellus (Fallén) (Hemiptera, Delphacidae)] is one of the most destructive insect pests rice and has developed serious resistance to several kinds chemical insecticides. Triflumezopyrim, a novel mesoionic insecticide by DuPont Crop Protection, an efficient biological activity control sucking insects, such as planthopper. However, effects triflumezopyrim on growth reproduction L. have not been reported. In this study, age-stage life table procedure was used...
Introduction: Spodoptera frugiperda is an important nomadic agricultural pest with a diverse host range and resistance against several insecticides. The current study investigated the life history traits of two strains field-collected population chlorantraniliprole using age-stage two-sex table. Method: For this, we established chlorantraniliprole-susceptible (Crp-SUS G 12 ), chlorantraniliprole-reduced susceptible (Crp-RES ) derived from sixth generation QJ-20 having ratio (RR) 10.39-fold,...
Spodoptera litura is one of the major agricultural pests in China, and it has developed serious resistance to many traditional chemical insecticides. In present study, bistrifluron-resistant (Bis-SEL) strain accompanied by a higher oviposition, 113.8-fold RR compared bistrifluron-susceptible (Bis-UNSEL) strain, was obtained bidirectional screening. A comparison their gonad coefficiency genes related oviposition or used elucidate resurgence mechanism.The ovarian index, potential egg...
Spodoptera litura is a widely distributed multifeeding pest, that has developed high resistance to many chemical insecticides. In the present study, bistrifluron-resistant (Bis-SEL) strain showing 113.8-fold ratio relative bistrifluron-susceptible (Bis-UNSEL) was obtained and showed fitness advantage (resurgence). First, we found observed resurgence might have resulted from Maf transcription factor overexpression in Bis-SEL strain, which would influence synthesis of ecdysone chitin....
The white-back planthopper (WBPH), Sogatella furcifera, mainly harms rice and occurs in most regions China Asia. With the use of chemical pesticides, S. furcifera has developed varying degrees resistance to a variety pesticides. In our study, chlorpyrifos-resistant population (44.25-fold) was built through six generations screening with sublethal dose chlorpyrifos (LD50) from field population. expression levels ten selected resistance-related P450 genes were analyzed by RT-qPCR found that...
