中文摘要:在 15 ,20 ,25 ,30和 35℃下 ,测定了棉露尾甲Haptoncusluteolus(Erichson)各虫态的发育历期。结果表明 ,卵到蛹各虫态历期随温度升高而呈抛物线变化 ,3 0℃时发育历期最短 ;成虫寿命及世代历期随温度升高呈负线性变化。对试验结果采用了 2种方法计算发育起点温度和有效
英文摘要:The developmental period of the pollen betle Haptoncus luteolus was determined under five constant temperatures (15,20,25,30 and 35℃). The results showed that the relationship between temperatures and developmental period from eggs to pupae fit th
