在辽宁省发現一种寄生于柞蚕寄生蝇蛹体上的食虫菌,鑑定为赤色穗状菌[Spicaria fumoso-rosea (Wize) Vassilijevsky],是我国首次詳細观察記载。此菌容易培养,在馬鈴薯、甘薯块上,以及馬、羊粪混和腐植土上都可以生长发育良好。致病力強,自然寄生率为3.4—20.3％;接种感染寄生率为10—100％。此菌除寄生于柞蚕寄生蝇蛹外,还可寄生于粘虫、苹果食心虫及家蝇等。本菌孢子发芽所需相对湿度为98—100％,在98％以下不能发芽;土壤绝对含水量15—55％时发生良好,尤以35％为最适宜。最适温度为20—24℃。小区接种試驗結果:在地面撒菌粉让寄蝇蛆爬行钻入,寄生率为72.98％;在土深3与5厘米处撒菌粉,寄生率为40.24％和43.98％。
In Liaoning Province, a parasitic insect parasitic on the parasitic fly pupae was identified as Spicaria fumoso-rosea (Wize) Vassilijevsky, which is the first time in China. The bacteria easily cultured in potato, sweet potato block, and horse, sheep manure mixed humus can grow and develop well. Strong virulence, natural parasitic rate of 3.4-20.3%; parasitic infection rate of 10-100%. In addition to parasites parasites in the tussah parasitic fly pupae, but also parasitic on armyworms, apple moth worms and house flies and so on. The spore germination required relative humidity of 98-100%, below 98% can not germinate; soil 15-55% absolute water content occurs well, especially 35% is the most appropriate. The optimum temperature is 20-24 ℃. Cell inoculation test results: In the ground sprinkle powder let fly maggot crawling drill, parasitic rate of 72.98%; soil depth 3 and 5 cm Department of bacterial powder, the parasitism rate was 40.24% and 43.98%.
