荔枝泥蜂透翅蛾的生物学特性及其防治

Biological characteristics and control of Sphecosesia litchivora

通过室内饲养和室外观察研究,对荔枝泥蜂透翅蛾各虫态的形态特征进行了描述,基本了解其生活习性及生活史。此虫在广西1年发生1代。以幼虫在寄主蛀道内越冬,4月下旬至6月初为成虫羽化期,5月至6月上旬产卵,6月中旬至7月上旬为卵孵化期。提出了荔枝泥蜂透翅蛾的初步防治建议。

Morphological characters of the adults, eggs, larvae and pupae of of Sphecosesia litchivora Yang et Wang were described, and its life cycle and habits were studied based on observations and collections in the field and rearing in the laboratory. One generation of this insect occurred per year, and it over-wintered as larvae in insect burrows. The new adults emerged from late March to early June, and laid eggs from May to early June. The eggs hatched from the middle of June to early July. The control methods were also discussed.
