摘要
探讨了在光照周期为１４Ｌ１０Ｄ、Ｒ．Ｈ．为７０ ％ ±５ ％ 的恒温（１２ ～３５ ℃） 条件下美洲斑潜蝇的发育、繁殖和存活，求得美洲斑潜蝇世代的发育起点温度与有效积温分别为８ ．７７ ℃和２９５ ．６９ 日度，给出了温度与各虫态发育速率间的函数关系．２０ ～２７ ．５ ℃时存活率较高，死亡主要发生在蛹期，３５ ℃下蛹不能羽化．成虫寿命随温度的升高而缩短； 种群增长指数于２７ ．５ ℃时达到最高．
This paper studied the development,survival and reproduction of vegetable leafminer ( Liriomyza sativae ) at eight constant temperatures (12,15,20,25,27.5,30,32.5 and 35℃) with 70%±5% R.H. and 14L10D photoperiod.The initiative development temperature and the available accumulation temperature were estimated to be 8.77℃ and 295.69 day degrees,respectively.The regression equations of development rate with temperature at various immature stages were given.The survival rates at various immature stages were higher at 20～27.5℃.Most of the death occurred at pupal stage,and no pupae could emerge at 35℃.The longevity of the adult decreased with increasing temperature,and the population growth index reached a peak at 27.5℃.
