摘要
在温度为 1 9± 0 .5℃、2 2± 0 .5℃、2 5± 0 .5℃、2 8± 0 .5℃、31± 0 .5℃和 34± 0 .5℃及光照周期为 1 8L:6D条件下 ,分别研究了温度对鸭跖草负泥虫 Lema diversa Baly.各虫态发育、幼虫取食量及变温对其成虫繁殖力的影响 ,建立了发育速度、发育历期的理论模型 ,同时得出温度与幼虫取食量无明显相关关系及 31± 0 .5℃转至 2 5± 0 .5℃ (幼虫 )和 1 9± 0 .5℃转至 2 5± 0 .5℃ (成虫 )两种变温条件能显著提高其室内成虫繁殖力。
As to \%Lema diversa\% Baly,under treatments of six levels of constant temperature (19℃,22℃,25℃,28℃,31℃,34℃) and photoperiod (18L:6D),an study of temperature on the development,food\|take of \%Lema diversa\% larva and caloric temperature on the reproduction in the adult was carried out.Theoretical models for growth duration and development speed were constructed.The food\|take of larva was not affected by the temperature.Under the caloric temperature (31℃ to 25℃ larva,19℃ to 25℃ adult),the number of eggs laid per female increased significantly.
