Popis: Developmental times were compared among four pure lines of wing-dimorphic Nilaparvata lugens generated by successive selections for the following designated characteristics: blackish short-winged (BS), blackish long-winged (BL), yellowish brown short-winged (YS) and yellowish brown long-winged (YL). When the nymphs were reared on rice seedlings at low density, the developmental time was in the order of BS = BL < YS = YL, while with an increase in rearing density, the time lengthened markedly in long-winged lines but only slightly in short-winged lines, rearranging the order to BS < BL = YS < YL. Among F1 progeny of BS × YL, the developmental time in short-winged phenotypes was the same as those of BS lines at any of the densities tested, but the long-winged phenotypes emerged as adults at intermediate time between BS and YL lines at high density. This method of inheritance of developmental time and the differences in the duration observed among the four pure lines suggest that the genes regulating wing form and body color expression are also involved in the regulation of developmental time.
