黑竹缘蝽在贵州的发生及生物学特性

黑竹缘蝽Notobitus meleagris(Fabricius)属半翅目缘蝽科。国内分布于浙江、福建、广东、广西、江西、四川、云南、贵州、台湾等省区。近2年发现在贵州严重发生。黑竹缘蝽在贵州铜仁1年发生2代,10月中旬以成虫在石缝、树洞及皮缝、柴垛等干燥而隐蔽的场所越冬,翌年4月中下旬开始活动,经补充营养后交配、产卵。每雌虫产卵1～2块,卵期4～7d,以若虫、成虫刺吸慈竹竹笋汁液,使竹子生长衰弱,严重时造成竹笋枯死。提出黑竹缘蝽有效的防治措施,并从天敌的利用方面进行探讨。

Then it supplements nutrition to go on copulates, female imago generates 1 to 2 eggs one time, keeping hatch the eggs for 4 to 7 days. The nymphae and imago of N. meleagris Fabricus. harms Sinocalamus affinis （ Rendle. ） Meclure. by pierced and sucked the bamboo shoot, leads the bamboo grow slowly and even dies. The paper has also introduced some effective measures to prevent and control the N. meleagris Fabricus. and how to utilize its natural enemies.
