旋孢子虫(Helicosporidium)系寄生于昆虫血淋巴内的原生动物,Chapman(1967)首次在路易斯安那野外库蚊幼虫的血淋巴内发现这类原虫。最近作者从路易斯安那查尔斯湖畔屠宰场附近的污水沟内捕获的两条黑须库蚊(Culex nigripalpus)幼虫体内找到一种近似于寄生性旋孢子虫(H.parasiticum),而在宿主特异性、致病性和孢子形态学上都有明显区分的孢子虫,作者称之为蚊类的旋孢子虫Helicosporidium sp.本文就后者对数种蚊虫的感染性进行了试验,以测定其作为蚊虫生物防治剂的可能性。
Helicosporidium, a protozoan parasitized in insect hemolymph, was first found by Chapman (1967) in the haemolymph of Culex pipiens larvae in Louisiana. A recent study by H. Parasiticum from two Culex nigripalpus larvae captured in sewers near Charles’ Lake Louise, Louisiana, identified H. parasiticum, , Pathogenicity and spore morphological distinctions between the sporozoites, the author called the mosquito Helicosporidium sp. In this article on the latter several species of mosquito infectivity was tested to determine its effectiveness as a mosquito Biological control agent possibilities.
