对来源于2001年在巴西中部塞拉多采集的土壤样品的昆虫病原真菌金龟子绿僵菌分离株IP 46进行了降低冈比亚按蚊成虫雄性和雌性存活率的能力测试。和一个.阿拉伯蚊在3.3 × 10（6）分生孢子cm（-2）浓度下暴露于涂布在试纸上的真菌6小时，降低了两种蚊子的每日存活率（HR = 3.14，p <0.001），其中An的死亡风险更高。gambiae s. s相对于An.（HR = 1.38，p <0.001）。在处理组中> 95%的蚊子尸体中观察到真菌孢子形成。结果表明，M. Anisopliae IP 46具有成为非洲疟疾媒介物种的生物控制剂的潜力，并且是进一步研究和开发的合适候选物。
The entomopathogenic fungus Metarhizium anisopliae isolate IP 46, originating from a soil sample collected in 2001 in the Cerrado of Central Brazil, was tested for its ability to reduce the survival of adult male and female Anopheles gambiae s.s. and An. arabiensis mosquitoes. A 6-h exposure to the fungus coated on test paper at a concentration of 3.3 x 10(6) conidia cm(-2) reduced the daily survival of both mosquito species (HR = 3.14, p < 0.001), with higher risk of dying in An. gambiae s.s relative to An. arabiensis (HR = 1.38, p < 0.001). Fungal sporulation was observed in > 95% of mosquito cadavers in the treatment groups. The results indicate that M. anisopliae IP 46 has the potential to be a bio-control agent for African malaria vector species, and is a suitable candidate for further research and development.
