| 摘 要： | 1978年在昆明温泉地区发生了金龟子的虫霉病大流行,病原菌经鉴定为金龟虫霉(Entomophthora brahmina Bose et Mehta)。本文对该菌的形态进行了观察,测定出每虫金龟(Heptophylla brevicollis Fair.)约产生休眠孢子76,800个;该菌在一块狭小的地段引起地方病,推测由于雨季的提前而使小面积的低频常在性感染向大面积流行性感染演变。

| Abstract: | An epidemic discase of beetle [Heplophylla brevicollia (Fair.)] infected by an entomogenous fungus was obscrved in Hot Spring region, Anning county, Kunming district, Yunnan in 1978. The pathogen was identified as Entomophthora brahmina Bose et Mehta. The morphology of the fungus has been carefully studied. It was estimated that each beetle [Heplophylla brevicollia (Fair.)] can produce about 76,800 resting spores. The fungus causes that an enzootic disease in a small area. It is inferred that the rainy season begins earlier, an enzootic infection of lower frequency in a small area develops towards an epidemic infection in a large area. |
