Abstract: Antennal morphology and sensilla of the green plant bug, Lygus lucorum Meyer Dür (Heteroptera: Miridae), were studied using scanning electron microscopy. The results showed that the linear antenna consists of the scape, pedicel and two flagellomeres. Two types of sensilla trichodea, two types of sensilla chaetica, two types of sensilla basiconic and one type of Böhm bristles were distinguished with the shapes and distribution of sensilla. No difference was found in the type and distribution of the sensilla between the male and female adults. The quantity and distribution of each sensillum, however, were different in different segment of antenna.

Key words: Lygus lucorum, antenna, sensilla, ultrastructure
