Abstract： The development of Pachliopta aristolochiae adaeus (Rothschild)was studied in the laboratory at five constant temperatures between 19 and 31℃. The results showed that the adult could not mate or lay eggs at 19℃, however, egg, larva and pupa could complete development, and their developmental times varied with temperature between 19 and 31℃. Of all the immature stages,developmental time for prepupal stage was the shortest,while that for the larval stage the longest at all temperatures tested. Temperature thresholds of egg, larva and pupa and the whole generation for development were estimated as 5.6, 11.6, 6.3 and 10.6℃, respectively, while their thermal constants were 117.7, 293.2, 270.9 and 1105.2 degree days, respectively.
