In the brown planthopper, Nilaparvata lugens, triacylglycerol (TG) content and its fatty acid composition were analysed by GLC and compared during three days after the final moult. This analysis compared long and short-winged morphs, which were derived from predominantly macropterous and brachypterous strains, and allowed to feed but not mate. For both sexes, the levels of TG on a dry weight basis in the long-wing form were 1.6 times higher shortly after adult eclosion for both sexes than those in the short-wing form. The ratios of TG content between the two wing-morphs increased to 2.8 times for females and 3.7 times for males two days after eclosion, the stage estimated to be the most adapted to migration. Thus the macropters apparently store considerably more fuels for fiight than the brachypters. In female macropters, TG per dry weight decreased slightly during the pre-feeding period but returned to the initial level two to three days later due to feeding, possibly providing energy for migration. In contrast, TG Ievel per dry weight in brachypters continuously declined, maintaining TG content per individual with gradual weight gain during this period, suggesting the storage of materials other than TG by feeding for ovarian development. In males, TG Ievel declined more in brachypters than in macropters, possibly refiecting greater adaption for copulation in the former and migration in the latter. Fatty acid compositions of TG were essentially the same for both morphs and also both sexes at the time of adult emergence, but the composition in brachypterous males changed greatly after one to two days of adult life.
