摘  要:
在完全不提供食物的条件下对黑缘红瓢虫成虫的耐饥力进行测定,试验结果表明:其阶段死亡率(M)与存活时间(T)之间可以用正态分布曲线拟合。而成虫的LT50取曲线中参数μ的值。同时LT50与成虫发育时间(t)之间也有线性相关关系:LT50=3.1385+1.9324t,即随着成虫发育,其饥饿耐受能力逐渐增强。

摘  要:
Starvation endurance ability of Chilocorus rubidus Hope adult was measured in the situation of lack of prey. The result showed that there was a close relationship between the stage mortality (M) and the survival time (T) of Chilocorus rubidus Hope adult and it could be imitated with a normal distribution equation.While the insect population mortality reached 50%, the starvation endurance threshold (LT50) was the value μ of normal distribution curves. There was linear relationship between LT50 and the developmental time (t):LT50=31385+19324t.Namely the starvation endurance ability of Chilocorus rubidus Hope adult also relied on their development.
