虫生真菌粉虱座壳孢Aschersonia aleyrodis是大有前途的粉虱和介壳虫杀虫剂.用6种大田常用农药在推荐浓度下,研究其在25℃下对座壳孢菌孢子萌发和菌丝生长的影响,发现甲氰菊酯和克螨特抑制其孢子萌发和菌丝生长,表明二者与本菌极不相容.吡虫啉、水胺硫磷和双甲脒能促进孢子萌发且后两者亦可加速菌丝生长,多菌灵对其孢子萌发起暂时促进作用然而抑制其菌丝生长.

The entomogenous fungus Aschersonia aleyrodis is a promising whitefly and scale insect control agent. Six widely used pesticides were assessed at the recommended concentrations for compatibility in vitro with A. aleyrodis. The effects of these pesticides on spore germination during the whole test periods (12, 15, 18, 21 and 24 h) and mycelial growth after 5 days of incubation at 25℃ were quantified. Generally, fenpropathrin and propargite had pronounced adverse effects on the fungus. These two pesticides either heavily impaired the development of the fungus or strongly inhibited its spore germination at 25℃ and resulted in fungistasis,which indicated that they were mostly incompatible. Imidacloprid, isocarbophos and amitraz had a stimulating effect on spore germination and the latter two showed a reversible inhibitory effect on the growth of fungus in the tests. However, carbendazim conducted a temporary stimulatory performance on spore germination but performed an inhibitory influence on hyphal development.
