| Abstract: | Objective]The research aimed to study the significant influence factors of the population quantity variations of Bactrocera dorsalis.Method]Using stepwise regression analysis,the population quantity variation laws of Bactrocera dorsalis in Jianshui County of Yunnan Province and the meteorological factors that caused its occurrence were analyzed.And the regression model was built.And the regression model was tested on the basis of the data in Jianshui County of Yunnan Province during 2004-2006.Result]The main meteorological factors that influenced the occurrence of Bactrocera dorsalis were relative humidity,the lowest monthly temperature and rainfall.Conclusion]This study will provide certain reference for the prediction researches on the time,quantity,and peak of Bactrocera dorsalis' occurrence. |
