Analysis of aerial insect species composition and population dynamics of Spodoptera frugiperda in Nanning
摘要
Abstract
[Aim]This study investigated the aerial insect species composition and the population dynamics of Spodoptera frugiperda in Nanning,aiming to identify the species composition and the dynamics of dominant pests,provide basic bases for pest monitoring and early warning,and formulate more effective strategies for the control of migratory pests.[Method]A searchlight trap aerial mo-nitoring station was set up in the scientific research base of Guangxi Academy of Agricultural Sciences,Wuming,Nanning.Insects were collected from April to December 2022,followed by classification,identification,and statistical analysis.[Result]A total of 181 insect species belonging to 45 families of 10 orders were collected by the searchlight trap.Lepidoptera,Hemiptera,Orthoptera,and Coleoptera were the dominant taxa.The dominant species was Physopelta gutta.The abundant species included S.frugiperda and S.litura.The common species were Physopelta cincticollis,Helicoverpa armigera,Diaphania indica,Spoladea recurvalis,Gryllotalpa orientalis,and Heortia vitessoides.The population dynamics of S.frugiperda showed five distinct peaks,with the occurrence period concentrated from July to October,and the peak trap catch observed from mid-August to early September.[Conclusion]The aerial insects in Nanning are characterized by high species diversity and abundance.These research findings provide a foundation and data for pest forecasting,prediction and scientific control.关键词
