摘要/Abstract

摘要： 禾灰翅夜蛾是一种多食性害虫,可危害匍匐翦股颖草坪草。本试验结合室内饲养法,对禾灰翅夜蛾在匍匐翦股颖草上的发生危害和生长发育情况进行了系统的观察研究。结果表明, 禾灰翅夜蛾幼虫取食匍匐翦股颖草的叶片及嫩茎,可对匍匐翦股颖草坪草造成毁灭性的损害;雌蛹的体重明显大于雄蛹的体重。在广州,禾灰翅夜蛾的最高产卵量为251粒/雌蛾,平均产卵量为54.6粒/雌蛾,卵块产。

Abstract: The turfgrass insect pest Spodoptera mauritia, is distributed in the south of China. It is polyphagous and Agrostis stolonifera is one of its turfgrass hosts. Field observations and experimental rearing methods were used to study the biology of S. mauritia fed on this turfgrass. In the field, the larvae could chew the turfgrass leaves and tender stems, causing severe damage. The weight of female pupae was greater than that of male ones. The highest productivity per female was 251 eggs, while the average productivity per female was 54.6 eggs. The eggs appeared in clusters when laid.
