In some species, such as aphids, the flightless morph lacks wings and is called the apterous morph. 一些昆虫种类,如蚜虫,出现无翅个体,被称为无翅型。
There was a close genetic relationship between the fundatrix ( apterous), virginoparae ( apterous) and virginoparae ( alate) in the green peach aphid. 干母、干雌和迁移蚜之间的遗传关系最近。
A significant linear relationship was found between the trapped aphid number and aphid incidence in current shoots. Thus, prediction confidence intervals of aphids on traps combining with the occurrence peak of apterous aphids in fields were suggested to estimate aphid occurence. 同时田间新梢蚜虫发生率与黄板上蚜虫诱集量有显著的线性关系,可以利用黄板上蚜虫诱集量平均值的预测区间结合田间无翅蚜发生高峰来预测田间蚜虫的发生情况。
