梭毒隐翅虫成虫捕食行为初步研究

梭毒隐翅虫Paederus fuscipes Curtis是农田常见的捕食性天敌昆虫，本文观察了梭毒隐翅虫雌、雄成虫捕食成蚜、幼蚜的行为，发现其捕食行为包括6个部分，即搜寻、捕捉、嚼食、梳理、静止和排泄。棱毒隐翅虫成虫在捕食成蚜、幼蚜的过程中，其嚼食时间有显著差异，幼蚜嚼食耗时较少，成蚜嚼食耗时较多，而梳理时间、静止时间没有显著差异。

Preliminary Study for Predatory Behavior of Adults of Paederus fuscipes Curtis

Paederus fuscipes Curtis is a common predatory natural enemy in farmland. In the observation of its adults' behavior in preying on aphids we have found that its predatory behavior consists of six parts: hunting, capturing, chewing, clearing, resting and excretion. During the predation on adult and child aphids, while there is no much difference in time spent on clearing and resting, marked difference exists in time spent by adults of Paederus fuscipes Curtis on chewing, that is, time spent on chewing adult aphids is much longer than that on child aphids.
