茶棍蓟马生物生态学特性及其防治

Bionomics and Control of the Tea Stick Thrips,Dendrothrips minowai Priesner

茶棍蓟马Dendrothrips minowai Priesner是我国茶树上的主要吸汁类害虫之一,其成虫和若虫均可为害茶树,导致叶片卷曲、脆硬、焦枯甚至脱落,严重影响茶树的自身生长和茶叶的品质口感。本文介绍了茶棍蓟马的形态与危害特征、个体发育和生活史、聚集等生物、生态学特性及其鉴定方法、地理分布、遗传分化特点,总结了其防控技术的研究进展,并提出需加快推进其嗅觉感受机制等基础研究,开发监测预警、大规模诱杀和病原菌防控等绿色防控技术,以期为茶棍蓟马的综合治理提供理论依据和技术支撑。

The tea stick thrips,Dendrothrips minowai Priesner,is one of the most important sucking pests in tea plantations in China.Both D.minowai adults and nymphs feed on fresh and tender tea leaves,causing leaves to turn curling,brittle and scorched and finally fall off,which seriously affect the growth of tea plants and the quality of tea products.In this paper,we reviewed the biological and ecological characteristics of D.minowai such as their morphological characteristics,damage symptoms,individual development and life cycle,as well as their identification method,geographical distribution,genetic differentiation.In addition,we also summarized the research progress on the management of D.minowai.At the same time,we suggest that the basic research of the olfactory mechanism and the green prevention and control strategy such as monitoring,mass trapping and the use of pathogenic resources of the pest should be accelerated.This review provides a theoretical basis and technical support for the integrated pest management of D.minowai.
