斜脉蝠蛾Hepialus oblifurcus Chu et Wang幼虫“黑点病”由粉质拟青霉Paecilomyces farinosus Brown et Smith引起。该菌在10—25℃温度范围内能正常生长,生长速度及分生孢子萌发率随温度升高而加快和增高。该菌对酸度要求不严。百菌清烟熏剂处理5秒钟即能显著抑制分生孢子的萌发。探讨了斜脉蝠蛾幼虫“黑点病”的药剂防治。
Larvae of Hepialus oblifurcus Chu et Wang larvae are caused by Paecilomyces farinosus Brown et Smith. The strain can grow normally in the temperature range of 10-25 ℃. The growth rate and germination rate of conidia are accelerated and increased with the increase of temperature. The bacteria lax requirements of acidity. Chlorothalonil fume treatment for 5 seconds that can significantly inhibit the germination of conidia. In this paper, the drug control of “black spot disease”
