玫烟色拟青霉(Paecilomyces fumosoroseus(Wize)Brown ＆ Smith)是一种世界性分布的重要昆虫病原真菌和土壤真菌。Sekiguchi,A(1959)已培养生产此菌进行了害虫的生物防治试验。曾省等人(1965)在国内也首次从榨蚕饰腹寄生蝇蛹体上分离报道了本菌。我们于1976—1977年在进行害虫病原微生物调查时发现,玫烟色拟青霉对茶树害虫的寄生范围十分广泛。 Angus(1965)、Bugers(1971)和Ignoffo(1976)都曾报道,分离自不同寄主昆虫,或同一寄主而地区不同的菌株,它们对同种试虫的致病力有明显差异。但对来自同一种昆虫而虫期不同的菌株其致病力有无差异则未见报道。 曾省等人(1965)和Madelin(1966)报道,玫烟色拟青霉在马铃薯块、畜类和黄豆饼粉上都能很好生长,抱子量可达60×10~8/
Paecilomyces fumosoroseus (Wize) Brown & Smith is an important insect pathogenic fungus and soil fungus distributed worldwide. Sekiguchi, A (1959) This strain of bacteria has been cultured for pest biocontrol testing. The province and others (1965) in the country for the first time from the silkworm exterminate parasitic flies pupa body isolated reports of the bacteria. In 1976-1977, we conducted a survey of pest pathogenic microorganisms and found that Paecilomyces aeruginosa has a wide range of parasitic effects on tea tree pests. Both Angus (1965), Bugers (1971) and Ignoffo (1976) reported that strains isolated from different host insects, or from different regions of the same host, have significant differences in their pathogenicity to the same species. However, there is no difference in the virulence of strains from the same insect but different stages. Zeng et al. (1965) and Madelin (1966) reported that Paecilomyces lugens grew well on potato pieces, livestock and soybean meal, with the amount of spores up to 60 × 10-8 /
