摘要:

目的 研究实验室条件下和野外环境中,球孢白僵菌CF08株在家蝇成虫种群中的水平传播能力。方法 采用生物测定方法,研究直接喷洒白僵菌孢子及接入感染后的家蝇对正常家蝇的感染情况。结果 球孢白僵菌CF08株对雌雄家蝇成虫的致病力差异无统计学意义(t=1.220,P=0.240);在实验室条件下,随着球孢白僵菌CF08株感染家蝇接入比例的增加,正常家蝇的死亡率显著提高,最高达近80%;在野外环境中,喷洒球孢白僵菌CF08株孢子或释放感染家蝇,对自然孳生家蝇的感染率均较低,最高为12%。结论 球孢白僵菌CF08株在实验室家蝇种群中的水平传播能力较强,野外环境下可能不适于蝇类的生物防治。

Abstract:

Objective To investagate the horizontal transmission of Beauveria bassiana CF08 strain in population of Musca domestica adults under the laboratory and field conditions. Methods After spraying spores or introducing infected houseflies to healthy houseflies, the prevalence of infection was recorded. Results The pathogenicity of B. bassiana CF08 strain between female and male houseflies had no significant difference (t=1.220, P=0.240). Under laboratory conditions, with the increasing proportion of infected houseflies in population, the infection rate of healthy houseflies increased up to 80%. But in the fields, the infection rate of healthy houseflies only to 12%. Conclusion Beauveria bassiana CF08 strain could horizontally transmit in house flies populations under laboratory conditions, but was not suitable for control wild house flies in the fields.
