摘要: 胡桃豹夜蛾Sinna extrema(Walker)是近年来在闽北出现的一种危害青钱柳的新害虫。1年发生6代,以老熟幼虫在矮小灌木、杂草及枯枝落叶中结茧化蛹越冬。幼虫共6龄,末2龄为暴食期。发生与气温、海拔、坡向及物候关系密切。越冬代成虫盛发期林间施放“741”烟剂;80%敌敌畏乳油1000~1200倍喷射3~4龄幼虫;于第1代、第6代老熟幼虫下树结茧高峰期之前,地面喷射50%辛硫磷乳油1000~1500倍或40%甲基异柳磷乳油1000~1500倍液,或喷布白僵菌粉剂,这些方法均可有效防治此虫。

Abstract: Sinna extrema(Walker) is the most important insect pest of Cyclocarya paliurus(Batal) Ilkinsk. In South China it infests leaves only. The paper deals with its bionomics and control measures conducted during 1994~1999 in Fujian Province. Laboratory rearing and field observation showed that this insect had six generations per year in Nanping city and SanMing city, Fujian Province. There are six larval instars, Overwintering takes place as pupa in cocoon at weeds and shrubbery and on the fallen leaves. The control methods of the pest are as follows: (1) Spraying with 50% Phoxim E.C 1000~1500× or 40% Isofenphos-methyl E.C 1000~1200× or Beauveria bassiana powder to eliminate mature larvae of the 1st and 6th generation before cocoonning. (2) Spraying with 80% Dichlorvos E.C 1000~1200×, to eliminate larvae of the 3rd~4th instar. (3) Dichlorvos used as smokes “741” was found to be effective against adults of the 6th generation.
