温度对红珠凤蝶小斑亚种发育的影响

Effect of temperature on development of Pachliopta aristolochiae adaeus

室内研究了红珠凤蝶小斑亚种Pachliopta aristolochiae adaeus(Rothschild)在19～31℃范围内5个恒温条件下的发育。结果表明,成虫在19℃时不能交配和产卵,而卵、幼虫和蛹在19～31℃范围内均能完成发育,且发育历期随温度而变化。各温度下,预蛹期最短,幼虫期最长,幼虫龄期随虫龄的增加而逐渐延长。卵、幼虫、蛹和世代的发育起点温度分别为5.6、11.6、6.3和10.6℃,有效积温分别为117.7、293.2、270.9和1105.2日·度。

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.
