Abstract:
... Acetylcholinesterase (AChE) is a vital enzyme that hydrolyzes acetylcholine. Here, full‐length complementary DNAs (cDNAs) of two acetylcholinesterase genes (SeAce1 and SeAce2) were obtained from Spodoptera exigua, a widespread phytophagous pest in agriculture. The complete SeAce1 cDNA comprised 5447 nucleotides including an open reading frame (ORF) encoding 694 amino acids, while SeAce2 cDNA encom ...

Abstract:
... The European grapevine moth, Lobesia botrana (Denis & Schiffermüller), is a serious pest in vineyards in North and South America. Mating disruption techniques have been used to control and monitor L. botrana on the basis of its sexual communication. This needs a well‐tuned olfactory system, in which it is believed that pheromone‐binding proteins (PBPs) are key players that transport pheromones in ...

Nilaparvata lugens; double-stranded RNA; genes; glycosylation; insect pests; mortality; nymphs; pest control; pesticides; protein subunits; rice; transferases
Abstract:
... RNAi‐based pest control strategies are emerging as environment friendly and species‐specific alternatives for the use of conventional pesticides. Because N‐glycosylation is important for many biological processes, such as growth and development, the early steps of protein N‐glycosylation are promising targets for an RNAi‐based pest control strategy. Through injection of dsRNAs, the expression of t ...

Abstract:
... Phospholipase A₂ (PLA₂) hydrolyzes fatty acids from phospholipids at the sn‐2 position. Two intracellular PLA₂s, iPLA₂A and iPLA₂B, have been found in Spodoptera exigua. Both are calcium‐independent cellular PLA₂. Their orthologs have been found in other insects. These two iPLA₂s are different in ankyrin motif of N terminal region. The objective of this study was to determine whether Toll/immune d ...
