The relationships between the readiness of fourth instar Aedes aegypti to metamorphose and their weight, nutritional reserves and sex were examined. Both the critical larval weight required for metamorphosis and the potential weight were influenced by the temperature at which the larvae were reared, and were greater for females than for males. Caloric levels of soluble carbohydrates and soluble lipids correlated strongly with weight. The accumulations of both carbohydrates and lipids were sex-dependent and were increased in both sexes at the higher temperature, but caloric levels of glycogen at the critical weights were all similar. We suggest that weight per se is not a critical factor in determining readiness to pupate, and that carbohydrate levels may be one important causal variable.
研究了埃及伊蚊四龄幼虫变态准备状态与其体重、营养储备和性别的关系。变态所需的临界幼虫体重和潜在体重均受幼虫饲养温度的影响，且雌性大于雄性。可溶性碳水化合物和可溶性脂质的热量水平与体重密切相关。碳水化合物和脂质的积累均具有性别依赖性，且在较高温度下两性均增加，但临界体重时糖原的热量水平均相似。我们认为，体重本身并非决定化蛹准备状态的关键因素，碳水化合物水平可能是一个重要的因果变量。
