几种表面活性剂及营养物对虫生真菌孢子萌发的影响

研究了球孢白僵菌、金龟录僵菌和粉拟青霉在吐温－８０及６种不同的洗衣粉中的分散性及活力。结果表明，３种真菌在这些表面活性剂中的分散指数差异不显著。白僵、绿僵不同浓度的吐温－８０液中的发芽同于不加表面活性剂的对照。多数洗衣粉显著抑制３种真菌的萌发，但白僵菌在０．１％和０．０５％白猫牌无泡超浓缩洗衣粉中发芽 对照差异不显著，在５％和２％葡萄糖液，２％和１％蛋白胨液中，白僵菌孢子在发者发育率最高。

Impact of Some Surfactants and Nutritions on Conidial Germination of Entomogenous Fungi

In the present stutly,the dispersality,viability(in terms of germination)ofthe conidia of Beauveria bassiana,Melarhizium anisopliae,and Paecilomyces farinosus in dif-ferent concentrations of Tween-80 and 6 common commercial powder detergents,The re-sults showed that the difference of dispersal indices of the conidia of the 3 fungi in these sur-factants was not significant.The germination rates in different concentrations of Tween-80 of B.bassiana and M. anisopliae were mostly higher than in control not treated in any surfactant with an exception of M,anisopliae in 0.2% Tween-80 lower than control.Al-most all detergents inhibited the germination significantly except B, bassiana in low concen- tration of one detergent.Conidia of B. bassiana in 5 liquid media,5% and 2% glucose,2%and 1% peptone,and 2% glucose pius 1% peptone resulted in the highest germination ofthe 3 fungi.
