朽木夜蛾的生物学特性及防治研究

BIOLOGICAL CHARACTERISTICS AND PREVENTION AND CURE OF AXYLIA PUTRIS L.

研究了朽木夜蛾的形态特征和生物学特性及防治的效果。朽木夜蛾在河北省秦皇岛和唐山地区 1年发生 3代 ,以蛹越冬。其幼虫第 1代发生于 5月中旬至 6月中旬 ,第 2代发生于 7月上旬至 8月中旬 ,越冬代发生于 9月中旬至 1 0月上旬。幼虫共 6龄。采用除虫菊洗衣粉 (1∶2 ) 2 5 0倍液和苏芸金杆菌 2 0 0倍液喷雾防治 ,杀虫效果达 1 0 0 %。也可用黑光灯诱杀成虫。

The morphological and biological characteristics of Axylia Putris L. and effects of harmless prevention and cure for the public were studied. Axylia Putris L. in Qinhuangdao and Tangshan of Hebei province has three generations in a year and lives through winter in the form of a pupa. The larva of the first generation appears between May 10 th and June 20th, the second generation between July 1 st and August 20 th , the winter generation between September 10 th and October 10 th . The larva has a six year lifespan. Spraying the solution of 250 times Dalmatian chrysanthemum laundry detergent (1∶2) with 200 times Bathurin is an effective method to kill all the insects. Another way to kill mature insects is to use black light (ultra violet lamps).
