Using electroantennogram (EAG) and single-sensillum recordings, we found that female Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) displayed distinct olfactory preferences for oviposition cues, host volatiles, and sex pheromones before and after mating. The injection of synthesized sex peptide (SP) or juvenile hormone (JH) into virgin females, as well as the knockdown of SP- or JH-receptors in mated females, reversed the olfactory preferences in both groups of flies. The onset of the effect of JH was relatively gradual, as evidenced by the lack of changes observed during the first 6 h after mating. The rapid changes in antennal sensitivities may involve specific neuromolecules, such as phosphatidylcholine (PC) and D-chiro-inositol (DCI), which were identified through metabolomics screening, and their functions were further validated by microinjection.

Chemical insecticides are commonly used to control them, but these methods are expensive and nonspecific. Therefore, RNA interference (RNAi) is being explored as an alternative strategy to control spongy moth. Juvenile hormones (JHs) play a crucial role in regulating insect growth, diapause, and reproduction, making them potential targets for pest control. This study investigated whether 2 enzymes involved in the JH pathways-JH acid methyltransferase (JHAMT) from the biosynthetic pathway and JH epoxide hydrolase (JHEH) from the metabolic pathway-could be used for RNAi-based control. Ldjhamt showed predominant expression during the larval stages and Ldjheh exhibited high expression throughout development. Both genes had the highest expression in the fat body. RNAi silencing using specific double-stranded RNAs resulted in a significant decrease in the expression level of target genes, as well as a significant reduction in larval survival rate, pupation rate and eclosion rate. Additionally, many larvae and pupae died due to developmental abnormalities, and the adult size of the treated group was smaller than the control group.
