摘要
烟草盲蝽在20世纪70年代中叶后,逐渐成为中国南方地区烟草、芝麻、泡桐、葫芦等植物的重要害虫,并能捕食一些鳞翅目幼虫、同翅目若虫及双翅目成虫等。尚能传染烟草普通花叶病和泡桐丛枝病,田间发病率与虫口密度呈正相关。江西年生4代,世代重叠,以成虫在温室、温泉的再生烟草上、杂草丛中、瓦片及乱石堆下、树洞、墙缝等处越冬;全年以8～10月为害最烈。在稍干旱的年份和烟草、芝麻、泡桐混种区发生尤重。选用抗虫品种、加强管理、喷施2.5％溴氰菊酯+80％敌敌畏乳油,可取得较好防效,亦可利用南方小花蝽等天敌,予以抑制。
Cyrlopellis lenuis (Reuter) has become an important insect pest of tobacco, sesame, paulownia and Lagenaria Vulgaris in the south China since the middle of 70s', and the pest can prey on some larvae of Lepidoplera, nymphs of IIomoplera and adults of Diplera. It can also spread TMV and MLO, whose incidences are in positive correlation with the population density. The pest reproduces four generations every year in Jiangxi and the generations overlap. The pest adults overwinter on the regenerating tobacco in green house and hot spring,in weeds,under rubbles and disorderly stones,or in the holes in the tree and the cracks in the wall. It causes the most serious harm from August to October every year, especially in drought year or in the regions where sesame is mix-planted with paulownia. The pest can be controlled by utilizing varieties resistant to the post ami strengthening field management and spraying the mixture of 2. 5% Decis+80% DDVP. Also,Orius similis zheng etc. (a natural enemy) can be used to prohibit the population growth.
