海南南部夜间空中昆虫群落结构研究

海南南部是中国农作物冬季南繁育种的重要基地。为了明确南繁基地空中昆虫群落结构,利用探照灯诱虫器于2017年-2018年监测了空中飞行的昆虫种类和动态。共计发现396种昆虫,隶属于13目88科307属,其中包括粘虫、棉铃虫、稻飞虱、稻纵卷叶野螟等重大迁飞性害虫以及黑肩绿盲蝽、异色瓢虫等迁飞性天敌昆虫。鳞翅目(206种,52.02%),半翅目(85种,21.46%)和鞘翅目(57种,14.39%)是该地区的三大优势目。本研究明确了我国重要的农作物南繁基地夜间空中昆虫群落的结构,为指导作物害虫测报和防控工作提供了依据。

Study on the community structure of nocturnal aerial insects in Southern Hainan Province

Hainan National Breeding and Multiplication Base (HNBMB) in Southern Hainan Province is an important platform for Chinaese crop breeding innovation in winter season. In order to clarify community structure of insect species there, we set up a vertical search light for collecting flying insect samples from 2017 to 2018. A total of 396 species of insects, belonging to 307 genera, 88 families, 13 orders, were found, including important migratory pests such as armyworm, cotton bollworm, rice planthopper, rice leaf roller and other migratory natural enemies such as Cyrtorhinus lividipennis and Harmonia axyridis Lepidoptera (206 species, 52.02%), Hemiptera (85 species, 21.46%) and Coleoptera (57 species, 14.39%) were three main dominant orders. These results indicated the insect species and their structure, and supplying a basis for guiding the population monitoring, control and prevention of crop pests.
