为评价利用球孢白僵菌F08菌株的分生孢子粉和奋斗呐5%可湿性粉剂制成的双效毒蝇绳对家蝇的控制效果,本研究对其在室内笼中、室外猪舍和垃圾处理场环境条件下对家蝇的控制效果进行了测试。结果表明:1室内和室外试验条件下,双效毒蝇绳对家蝇的控制效果都优于奋斗呐毒蝇绳和球孢白僵菌毒蝇绳。3种试验条件下,双效毒蝇绳对家蝇的校正防治效果与球孢白僵菌毒蝇绳间有极显著差异(P<0.01);且在猪舍试验条件下,其校正防治效果与奋斗呐毒蝇绳组1周时有显著差异(P<0.05),2周时有极显著差异(P<0.01)。2球孢白僵菌对家蝇的感病率仅在室内笼中狭小空间时在球孢白僵菌毒蝇绳组和双效毒蝇绳组有显著差异(P<0.01),而在猪舍或垃圾处理场试验条件下无显著差异(P<0.05)。说明双效毒蝇绳中的球孢白僵菌F08菌株与奋斗呐具有较好的兼容性,一起对家蝇发挥很好的控制作用。
In order to evaluate the control effect on the housefly by using the double-acting poison flies made of Fosp strains of Beauveria bassiana F08 and the 5% WP of Fighting na, And control effects of house flies under the environmental conditions of garbage disposal sites. The results showed that: 1 indoor and outdoor test conditions, double-effect poisoning fly control effect on house flies are better than those fighting flies bombardment and Beauveria bassiana fly fly rope. Three kinds of test conditions, the double-effect poisoning fly housefly correctional control effect and Beauveria bassiana poisoning flyweights have significant differences (P <0.01); and in the pighouse test conditions, the correction control effect There was a significant difference (P <0.05) between the two groups at 1 week and that at 2 weeks (P <0.01). 2 Beauveria bassiana susceptibilities to house flies were significantly different (P <0.01) between the Beauveria bassiana Aeromonas spp. Group and the double-effect ducks group (P <0.01) only in the narrow cages in the indoor cages There was no significant difference (P <0.05) between house and waste disposal sites. It shows that the Beauveria bassiana F08 strain in the double-effect poisonous fly ropes has good compatibility with the fighting na and plays a very good controlling role together with the housefly.
