摘要
以纯化的嗜热多拟青霉液体发酵培养,测定其代谢产物对棉蚜和温室白粉虱的毒杀效果。用水培棉苗法培养棉蚜,盆栽番茄培养温室白粉虱,采用菌株发酵产物浸渍法进行生物测定。结果表明:该代谢产物表现出较高的毒杀作用,室内生物测定72 h对棉蚜和温室白粉虱的校正死亡率分别为80.5%和66.3%。
The purifided Polypaecilum thermophilum D. M. Wang et D. C. Li was cultured by fermentation, and the effects of its zymotic metabolites on Aphis gossypii raised on water - planting cotton seedlings and Trialeurodes vaporariorum raised on potted tomato plants were studied. The bioassay was conducted through dipping leaves in fungi zymotic metabolites. The results showed that the zymotic metabolites had higher toxicity to Aphis gossypii and Trialeurodes vaporariorum with adjusted mortality of 80.5% and 66.3% respectively after bioassay for 72 hours.
