摘　　要：为了掌握竹织叶野螟在赤水的发生特点，探讨其有效的综合防治措施。采用室内外观察饲养的方法，时该虫的生物学特性进行了系统的研究。结果表明：竹织叶野螟在赤水1年发生4～5代，以4代居多，以老熟幼虫在土茧中越冬；翌年4月上旬化蛹，4月中旬成虫羽化．4月下旬成虫开始产卵。不同饲喂条件下的平均产卵量不同，用10％蜂蜜水饲喂时平均产卵量最高为599粒。竹织叶野螟天敌较多，其中，幼虫期天敌寄生率最高达13．8％～37．1％。提出了灯光诱杀、人工摘虫等有效的防治方法。The biology character of Algedomia coclesalis was studied based on field investigation and laboratory feeding. Results showed it had 4 to 5 generations per year, mostly 4, and its old larvae over winter as cocoons in soil, became pupa in early April, adult in mid April, and lay eggs in late April in next year. The average eggs depended on the feed condition, maximum eggs were 599 when feed honey and water mixture （v ： v is 9 ： 1）. Some effective control measures such as light trap, manual capture, and parasite enemies etc. are proposed in this paper based on the above characters.
