蝗噬霉菌(Entomophthora gryui)又名蝗虫霉,属真菌,以分生孢子在田间传播,使蝗虫致病直至死亡。在山西忻州地区普遍可以见到,一般寄生率20～30％,高的达50％以上。多发生在夏蝗后期,以8～9月份在稻田内屡见不鲜。高温高温季节最易传染、流行。 从蝗种来看,以中华稻蝗(Oxya chinensis)、小车蝗(Oedaleus infernalis)寄生率高、死亡时间也快;而尖头蚱蜢(Atractomorpha bedeli)等寄生率低。据大田观察,窝

Entomophthora gryui, also known as locust, is a fungus that spreads conidia in the field and causes locusts to become ill until they die. In Xinzhou, Shanxi Province can generally be seen, the general parasitic rate of 20 to 30%, high of more than 50%. Occurred in the late summer locust to 8 to 9 months in the rice fields are not uncommon. Hot and hot season the most contagious, popular. In terms of locust species, Oxya chinensis and Oedaleus infernalis have high parasitic rates and fast death times, while parasitic rates such as Atractomorpha bedeli are low.
