樟曼盲蝽的形态特征及在上海的发生情况

摘要

樟曼盲蝽(Mansoniella cinnamomi)是近年来在香樟上发现的新害虫.本文报道了该虫形态特征和在上海的发生情况.比较了居民区绿地、生态防护林、行道树、公园绿地4种不同绿地类型中的虫情发生差异.樟曼盲蝽成虫体型狭长,红褐色；卵光亮、半透明、长茄形；若虫分5龄,半透明,光亮,鲜绿色,长形.该虫在上海18个区县均有发生,大部分地区株害率均为100％,为害程度较严重的分别为挹翠苑、东方苑、四和花园、闵行东方花园、松江中山西路、古华新村、长江农场,这些地点虫情指数均大于80％；4种不同绿地类型中樟曼盲蝽为害程度差异显著,居民区绿地中发生最为严重.%Mansoniella cinnamomi is a new pest feeding on Cinnamomum camphora. In this paper, we reported its morphology and occurrence in 4 different greenbelts, residential green spaces, ecological protection forests, street trees and parks in Shanghai. The adults were long oval and mahogany) the eggs were lucent, translucent, and long eggplant-shaped; the nymphs were translucent, lucent, reseda and length-shaped and had five instars. M. cinnamomi was found in 18 districts and counties in Shanghai. The damage rate was 100% in most areas. The highest pest indexes (> 80%) were observed at Yicui Court, Dongfang Court, Sihe Garden, Minhang East Garden, Songjiang West Zhongshan Road, Guhua Village and Changjiang Farm. The damage was significantly different among the four greenbelts, and the highest was in the residential green spaces.
