Ⅰ、导言大多数昆虫病原真菌属半知菌。已知大约有30个属含有一种或多种真菌能感染昆虫。它们的分类较混乱,误名和乱用学名也常有发生。本文提出了一个常见重要昆虫病原真菌的检索表,并列出了含有一种或多种昆虫病原真菌属的名录。对昆虫的致病性未被证实的一些属,如青霉,茎点霉(Phoma),或鉴定值得怀疑的分类单位则被略去。第Ⅶ部份介绍了一些真菌学术语。 相似文献

In a recent paper, V. Michelsen(1988, Systematic Entomology 13: 271–314) revised 18 world species of anthomyiid cone and seed
pests and described a new genus,Strobilomyia gen. n. He consideredS. melaniola of Northeast China to be a synonym ofS. viaria of North America. That they are the same species is not accepted. We compared the morphological characters of male and femaleS. melaniola adults with the close relatives,S. viaria andS. sibirica. We conclude that they are not the same species and that S.melaniola is an independent species. 相似文献

This study was carried out to determine the development, survival and reproduction responses of Adalia fasciatopunctata revelierei (Mulsant) (Coleoptera: Coccinellidae) feeding on Hyalopterus pruni (Geoffroy) (Homoptera: Aphididae), using 20, 40, 80, 160 and 250 prey densities. All experiments were conducted at 25±1°C,
60±5% relative humidity, 16:8 light:dark under laboratory conditions. The average daily prey consumption of A. fasciatopunctata revelierei immatures and adults increased with increasing prey densities. Predation was not different for the larval stages at 80, 160
and 250 prey densities. The longevities of adult females were 35.67, 35.33, 49.00, 58.33 and 57.16 days when 20, 40, 80, 160
and 250 H. pruni were provided, respectively. The mean daily and total fecundity of A. fasciatopunctata revelierei increased with increasing prey densities. Females of A. fasciatopunctata revelierei feeding on H. pruni laid 89 eggs at 20 prey density and 301.67 eggs at 160 prey density. The search rate of females was higher than that of
all larval instars; and the search rate of the fourth-instar larvae was higher than that of younger instars. Handling time
decreased with development from larval stages to adult. 相似文献
