Ultrastructure of sensilla on the antennal pedicel of the brown planthopper Nilaparvata lugens Stal (Insecta: Homoptera).

摘要: Scanning- and transmission electron-microscope studies of the sensilla pedicel Nilaparvata lugens have revealed an elaborate plaque organ three structurally different types trichoid hairs. Each is innervated by 120–150 neurons arranged in groups. The porous sensory cuticle folded into finger-like projections surrounded protective non-sensory denticles. Trichoid differ number neurons, appearance dendrites arrangement pores. Type I, 2 has pores along its length probably olfactory function. Types II III are one five respectively, absence hair shaft indicates a possible gustatory role. importance these discussed with reference to behaviour this important insect pest.
