平菇眼菌蚊Lycoriella sp.春季发生规律及防治的初步研究

Preliminary Studies on Bionomics and Control Methods of Lycoriella sp. Occuried in Spring

经1988～1990年调查和饲养观察,证明平菇眼菌蚊Lvcoriella sp.在豫西能以幼虫,蛹在室外越冬,其场所主要是废料堆、垃圾堆、土粪堆20cm以下深层废料袋。在室内则能同年繁殖。每年为害最严重的春季,该虫可发生3代,虫量逐代上升,且成虫雌性比例持续维持在80％以上。完成一代在8.5～12.5℃需25天,12.5～17℃对需20天。药液浸袋、拟除虫菊酯类杀虫剂喷雾,10％蚊蝇净烟熏分别对幼虫、成虫有较好的防治效果。

This paper presents the results of the investigation and observati-on carried from 1988 to1991 on bionomics of mushroom pest Lycoriella sp. occuried in spring, and of some studies on control methods. The results shown that Lycoriella sp.can overwinter with larva and pupae-under 20 cm in the waste medium-bag pile outside door and can reproduce all the year in cultivation room. The pest has 3 generations in spring cultivation period. The rate of femail adults each generation st-sy atleast over 80%.The pest develop one generation in 25 days under the condition of 8.5-12.5 C and in 20 days under 12.5-17.0 C. The infusion with pestisides into medium bags, spraying Decis and other similar llic micals and using smoke agentlO%WEIYINGJING can get good control results.
