| 摘 要： | 【目的】明确乙基多杀霉素SC、苏云金杆菌SC、阿维菌素WDG、甲氨基阿维菌素苯甲酸盐EW、球孢白僵菌WDG5种生物杀虫剂对稻纵卷叶螟的防治效果,筛选出可替代化学农药防治稻纵卷叶螟的生物农药。【方法】供试药剂设高、中、低3个剂量,与常用化学农药推荐剂量及空白处理进行比较。【结果】药后12d,6%乙基多杀霉素对稻纵卷叶螟的防治效果为97.45%～98.89%,8000IU/μL苏云金杆菌的防治效果为81.31%～91.68%,10%阿维菌素的防治效果为77.27%～90.61%,2%甲氨基阿维菌素苯甲酸盐的防治效果为79.62%～89.21%,400亿孢子/g球孢白僵菌的防治效果为75.62%～86.54%。【结论】乙基多杀霉素等5种生物农药对稻纵卷叶螟的防治效果与化学农药相当,甚至更高,可替代化学农药用于防治稻纵卷叶螟,建议在生产上推广应用。

| Abstract: | Objective]The objective of current study was to determine the efficiency of five biological pesticides for controlling Cnaphalocrocis medinalis in order to screen a biological pesticides which could be used as an alternative to chemical pesticides for controlling C. medinalis. Method]Three levels (high, moderate and low treatment) of biological pesticides (spinetoram SC, Bacillus thuringiensis SC, abamectin WDG, proclaim OR and powder of Beauveria bassiana WDG) were used as treatment to compare their effe... |
