温度对丝带凤蝶生长发育的影响

Effect of temperature on development in Sericinus montelus

温度对丝带凤蝶生长发育的研究。结果表明,丝带凤蝶在武汉地区1年发生6代。在15-35℃范围内,卵孵化率、幼虫和蛹存活率分别在25,25和20℃时最高,卵、幼虫和蛹发育历期随温度升高显著缩短;适宜发育温度范围为20-35℃。丝带凤蝶卵、幼虫和蛹的发育起点温度分别约为（8.7±2.5）℃、（11.9±6.0）℃和（6.9±1.8）℃,有效积温分别约为（82.5±5.1）,（222.2±39.5）和（178.7±7.3）日.度。

Sericinus montelus Gray was investigated in Wuhan area and effects of temperatures on its development were measured. The results showed that this butterfly could complete 6 generations from April to August, and overwinter as pupa from the end of September to the end of March of next year in Wuhan. Within the range of 15 35℃ combined with a photoperiod of 14L： 10D, egg hatching, survival of larva and pupa was the highest at 25, 25 and 20℃ respectively. The developmental periods of eggs, larvae and pupae decreased significantly with temperature increasing. Optimal temperature for development ranged from 20 to 35℃. Moreover, the developmental threshold temperatures of the eggs, larvae and pupae was estimated as （ 8.7 ± 2.5 ）, （ 11.9 ± 6.0 ） and （ 6.9 ± 1.8 ） ℃, respectively. The effective accumulative temperature the eggs, larvae and pupae are（82.5 ± 5.1 ）, （222.2 ± 39.5） and （.178.7 ± 7.3） degree-days, respectively.
