灰褐谷蛾生物学特性及其防治研究

灰褐谷蛾是灵芝等食用菌的主要害虫之一，严重影响其产量和质量。它不仅为害生产中正在生长的食用菌，即使贮存的生产成品，亦可被蛀食为害。该害虫在安徽六安年发生2代，以幼虫越冬。幼虫有群集钻蛀性。成虫盛发期喷洒80％敌敌畏乳油800～1000倍稀释液，可杀灭成虫；幼虫发生期喷洒敌敌畏薰杀幼虫效果可达95％以上。对贮存的生产成品，采用磷化铝熏蒸和50～60℃烘干杀虫效果均好。

Studies on the bionomics of Tinea metonella Pierce et Metcalfe and its control

Tinea metonella Pierce et Metcalfe is one kind of the main pests of edible fungi, especially inGanoderma lucidum cultivation. It heppens 2 grnerations per year in Liuan Prefecture, Achni Province. It sur-vives the winter in larvae. The larvae has the characters of boring and living in group, it harms the fruitbodies ofGanoderma lucidum both in growth and in storage, so severely dripairs its yield and quality. Our test result shows,over 95% larvae can be killed by fumigation with DDVP, and the imagoes also can be killed by DDVP in peak period. By fumigation with phostoxin or baking at 50 ~ 60 ℃ before storage, the fruitbodies can be well protectedfrom pest harming.
