Study on Integrated Control against Bactrocera dorsalis in Guava Orchard
摘要
Abstract
[ Objective ] To explore the damage,occurrence law and integrated control methods of Bactrocera dorsalis in Nanning region of Guangxi Province. [ Method ] Using fixed system survey method,with fly attractant as the materials, the occurrence dynamic of B. dorsalis adult in guava orchard was investigated. The control effects of the methods such as fly trap agent ,fruit bagging,cleaning park to pick up fallen fruit and timely spraying against the pest were also studied. [ Result]B. dorsalis had two damage peak periods in Nanning region of Guangxi Province (May-June ,August-September). Through the integrated control measures of trapping agent for male flies,timely spraying,fruit bagging and cleaning park to pick up fallen fruit,the population density in guava orchard dropped significantly. The damage rates of guava in research base were only 6.67％ -7.33％ during the peak period of B. dorsalis in June 2008,while they were 90.53％ -98.00％ in control area,obtaining good eontrol effect against B. dorsalis. [ Conclusion ]The research results not only preliminarily restored the yield losses of guava,but also provided basis for the preparation of overall strategy against B. dorsalis in the region.关键词
