Observation on the antennal sensilla of {\sl Sogatella furcifera} （Horváth） （Homoptera:Delphacidae） with scanning electron microscope

Sogatella furcifera （Horvath） is one of most important pests of rice. Morphology of antennal sensilla of S. furcifera was observed with scanning electron microscope. Three types of sensilla and a kind of sensilla cluster were observed on the antenna of the adult, and no morphological difference was found in these sensilla between the male and female adults. The number of sensilla increased with the development of S. furcifera nymph, especially after ecdysis and eclosion.
