阿克苏苹果叶螨生物防控试验
Experiment on Prevention and Control of Spider Mites in Aksu Apples
摘要
Abstract
[Objective]To study the control effect and feasibility of predatory mites carrying Beauveria bassiana spores on harmful mites in Aksu apple orchards.[Methods]In the field,three treatment plots were set up:a biological control plot(re-leasing predatory mites carrying Beauveria bassiana spores),a chemical control plot,and a blank control plot.Periodic sur-veys were conducted on the population dynamics of eggs and pest mites(adult mites,nymphs,and larvae)in each treatment plot.The population reduction rate was calculated to compare the control effects of different measures.[Results]The chemi-cal control effect was the fastest and most significant,with the maximum control efficiency reaching 91%.The biological con-trol effect showed a slowly increasing trend,peaking 20 days after release,with a population reduction rate of 36.8%,which was a highly significant difference(P<0.05)compared with the blank control plot(with a reduction rate of-96%).[Con-clusion]Using predatory mites carrying Beauveria bassiana spores to control harmful mites in apple orchards has a good con-trol effect,but external factors have certain impacts on the control efficacy.关键词
