Abstract: The type, distribution and ultrastructure of sensilla on the antennae of nymph, pupa, adult female and male of Dendrothrips minowai Priesner thrips were observed under the scanning electron microscope (SEM). Results showed that nine kinds of sensors existed on D. Minowai thrips, which were Böhm bristles, sensilla campaniformia, basiconic mastoid sensillum, sensilla chaetica, sensilla basiconica, sensilla coeloconica, sensilla cavity, sensilla auricillia and unusual sensillum. The sensilla chaetica and sensilla basiconica contained three and four subtypes, respectively. The type and distribution of sensilla significantly varied among different developmental stages: 1) Eight types of sensilla except basiconic mastoid sensillum were existed on the adult female. 2) Seven types of sensilla were existed on adult male other than basiconic mastoid sensillum and sensilla coeloconica. 3) The nymph possessed eight types of sensilla except sensilla auricillia, and with distinctive basiconic mastoid sensillum. 4) The types and number of sensilla on pupa were the least, only with sensilla chaetica and sensilla basiconica.
