Functional map of the macroglomerular complex of male Helicoverpa armigera
Graphical AbstractThe macroglomerular complex (MGC) of the primary olfactory center in male moths is the first site for receiving female-produced pheromones from antennal sensilla. Combined with single sensillum recording/anterograde filling and intracellular recording/retrograde filling, the function of 3 MGC units, that is, Cu, DMA, and DMP, related to the 3 types of pheromone sensitive sensilla trichodea was clarified, revealing the distinct male-specific olfactory neural pathway at the peripheral level inHelicoverpa armigera. AbstractThe mechanism of sex pheromone reception in the male cotton bollwormHelicoverpa armige...

Insulin peptides and their receptors regulate ovarian development and oviposition behavior in Diaphorina citri
In this study, the expression of upstream factorsDcILP1,DcILP2, andDcIR in the insulin signaling system ofD.  citri was upregulated after feeding on young shoots. After being silenced by RNA interference technology, the results showed that the number of oviposited eggs ofD.  citri was significantly decreased and the ovarian development was inhibited with severe vacuolation. In addition, detection using quantitative reverse transcription –polymerase chain reaction showed that the upstream regulatory geneDcRheb of the target of rapamycin (TOR) pathway and the downstream reproduction-relatedDcVg gene were also significant...
