摘要：

为掌握梨小食心虫发生规律，2010～2014年在辽宁省大连市金州区东、西部2个试验点，利用屋式诱捕器对梨小食心虫成虫发生进行动态监测。在此基础上，结合同期气象资料，分别研究春、夏不同季节梨小食心虫成虫发生期、发生量与气象因子的关系。结果表明：春季平均气温与梨小食心虫越冬代成虫发生期相关性显著。每年自3月中旬开始，当旬平均气温的累积值≥30 ℃的下一旬将是越冬代成虫的发生期。夏季，气温、日照条件正常，降水量多的年份，梨小食心虫发生量多。大连金州区梨小食心虫的代数为3～4代，各代高峰期的间隔约20 d，其后6 d为卵期，此时是最佳防治期。掌握越冬代成虫发生的高峰，用间距法预测其它各代高峰期，以期达到早预测早防治的目的。

Abstract:

In order to master the occurrence rule of oriental fruit moth, the amounts of oriental fruit moth in two test sites of the eastern and western Jinzhou district of Liaoning Province from April to September 2010 to 2014 were monitored by using the traps. Combined with the meteorological data, the relationship between the adult occurrence period, amounts of oriental fruit moth and meteorological factors in spring and summer were analyzed by using correlation analysis method. The results showed that the average temperature in spring had a great contribution to the occurrence period of overwintering generation adult. Beginning in the middle of March, when the cumulative value of ten-day average temperature was greater than or equal to 30 ℃, the next ten-day would be the occurrence period of overwintering generation adult. Under normal conditions of average temperature and sunshine duriation in summer, the precipitation was more, and the amount of oriental fruit moth was more. The number of generation of oriental fruit moth in Jinzhou distict of Dalian was generally 3-4 generation, the interval of outbreaking peaks between each generation was 20 days, and the following 6-day was the egg stage, it was the best period for control. Therefore, the prevention and cure can be done early by using the interval method to predict the peak of other generation after the occurrence peak of overwintering adult.
