虫生真菌粉虱座壳孢Aschersoniaaleyrodis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。
Aspergillus foetidus Aschersonia aleyrodis is a promising whitefly and scale insecticide. Six common field pesticides were used at the recommended concentrations to study their effects on spore germination and mycelial growth at the temperature of 25 ° C. It was found that fenpropathrin and propargite inhibited their spore germination and mycelial growth, indicating that The two are very incompatible with this bacterium. Imidacloprid, isocarbophos and amitraz can promote spore germination and the latter two can also accelerate mycelial growth. Carbendazim temporarily promoted the spore germination but inhibited its mycelial growth.
