扶桑绵粉蚧主要天敌昆虫种类调查(9100字)
摘 要：扶桑绵粉蚧(Phenacoccus solenopsis Tinsley)属半翅目、粉蚧科、绵粉蚧属，是一种危害园林、水果、大田作物的害虫，对我国棉花等产业造成危害的潜在风险巨大。此虫无论何种虫态，均可随扶桑等多种农、林植物传播扩散，繁殖速度快，寄主范围广，包括棉花、蔬菜和观赏作物等，必须严格控制。此实验通过对扶桑绵粉蚧的天敌昆虫调查，在5至10月期间通过在棉田中的直接采集和引诱采集，室外纱笼饲养采集，室内饲养采集，捕捉到寄生性天敌昆虫班氏跳小蜂（Aenasius bambawaleiHaya），捕食性天敌昆虫鞘翅目，瓢虫科的黑缘红瓢虫(Chilocorus rubidus Hope)，二星瓢虫(Adalia bipunctata) ，七星瓢虫(Coccinella septempunctata)，龟纹瓢虫Propylaea japonica Thunberg，多异瓢虫(Hippodamia conglobata)，十九星瓢虫(Anisosticta nouemdecimpunctata)。通过对扶桑绵主要天敌昆虫种类的调查，利用主要天敌昆虫保护扶桑绵粉蚧的寄主，防治扶桑绵粉蚧的繁殖，为该虫的预测预报和防治提供科学依据。
