Study on antennal sensilla and host preference analysis of Nilaparvata lugens (Stal)

R Aruna, S Jeyarani, S Mohankumar and C Durairaj

The present study was conducted to document the sensilla present on the antennae of Nilaparvata lugens in the Department of Agricultural Entomology, Tamil Nadu Agricultural University, Coimbatore during the period 2012-13. The results showed that the antennae of N. lugens were comprised of three distinct parts viz., scape, pedicel and flagellum. Plaque organs and trichoid sensilla were confined to the pedicel. The number of plaque organs on the pedicel increased with nymphal development. There were no difference in number and structure of sense organs of various forms and sexes. Two morphological types of hairs such as mechanoreceptive hairs and chemoreceptive hairs were distributed all over the pedicel of adults. The host preference study with N. lugens revealed that both nymph and brachypterous forms showed more preference for TN1 than Ptb33, while the macropterous form showed more preference for Ptb33.
