Abstract: The developments of wing pads and indirect flight muscles (IFM) in themacropterous and the brachypterous brown planthopper [Nilaparvata lugens (Stal)] were studied with paraffin method. The developmental differentiation of the IFMs occurred between the 8th and the 16th hour of the 4th nymphal instar, after which the IFMs of the macropterous nymph developed normally while the IFM development of thebrachypterous was suppressed. The wing pad developmental fferentiation was observed only at the 5th nymphal instar. The front wing pad cells of the brachypterous nymph proliferated slower than those of the macropterous and the development of hind wing pads of the rachypterous broke down. The wing dimorphism differentiation sensitive instar was inferred and compared between the male and female individuals.
Key words: the brown planthopper [Nilaparvata lugens (Still)], wing dimorphism, in- direct flight muscle, wing pad, sensitive nymph instar
