摘要: 对印度雕蚀菌在三带喙库蚊幼虫体内的发育进行了观察,表明1龄幼虫可被真菌所感染,菌体在蚊幼虫血腔内随虫体长大和变态而产生大量孢子囊,即完成其孢子增殖阶段,不再继续发育。孢子囊由死亡腐烂的蚊幼虫体释放于水中,在34℃下经8—12h的发育,囊内游动孢子成熟,于适宜条件下经1/2—1h可全部从囊中逸出。游动孢子在水中极为活跃,1h后活力下降,它为感染剑水蚤宿主的感染期。

Abstract: The present paper reports the development of Coelomomyces indica in Culex tritaeniorhynchus larvae.Experimental observations indicated that the first instar of the mosquito larvae can be infected with fungus.The hyphal bodies developed and produced sporangia in the haemocoele of the mosquito larvae.The sporangia were released in water from the dead mosquito larvae.The development of mature sporangia with zoospores was in water at 34℃ within 8 12 hours.The zoospores released from the mature sporangia within 1/2 1 hour under optimal conditions were very active in water and their activities decreased after 1 hour.The zoospores act as the infective stage for the Cyclops (host).
