英文摘要	Highly developed chemoreception allows insects to detect foods, find mates, and escape natural enemies. We described the structures and distributions of antennal chemosensilla in Adelphocoris fasciaticollis Reuter by scanning electron microscopy and transmission electron microscopy. Seven major types of antennal sensilla were identified in adults of both sexes. Types 1 and 2 are sensilla chaetica and have thick cuticular walls with conspicuous grooves at their surfaces. Types 3 and 4 are multiporous sensilla trichodea with 1-3 dendrites located at the sensillum lymph, indicating a putative olfactory function. Types 5 and 6 are typical sensilla basiconica but share different characteristics in both external morphology and internal ultrastructure, and may be involved in the perception of host-associated odorants. The last sensilla were Bohm bristles. In addition to the morphological characterization, electrophysiological responses of antennal chemosensilla to 51 semiochemicals were investigated based on electroantennogram (EAG) recordings. Results revealed that different chemical stimuli elicited significantly different dose-dependent EAG responses, in which potential sex pheromone components and green leaf volatiles showed relatively higher EAG responses, but neither monoterpenes nor sesquiterpenes can elicit favorable EAG values. The results provided direct morphological and electrophysiological evidence that the adult antennae of A. fasciaticollis could function in searching for mates and host plants.
