摘要： 为了明确牡丹江地区大豆食心虫的种群动态及其与气象因子的关系，试验于2010—2012年利用性诱剂诱捕法在田间进行了系统的调查。结果表明：牡丹江地区大豆食心虫的始见期在7月末，高峰期在8月初至8月中旬，结束于8月末，发生期历时1个月左右；在降水量偏少的年份大豆食心虫的种群动态与日平均温度呈显著正相关，适量的降水会造成空气湿度大，这有利于蛾量的增加，而强降水的出现不利于食心虫的化蛹和成虫出土；在牡丹江地区日平均气温在21~24℃为大豆食心虫的发生适温，而持续的高温、干旱天气不利于成虫的发生。说明温度与降水量均为影响大豆食心虫发生的重要因子。

Abstract: In order to specify the population dynamics of Leguminivora glycinivorella in Mudanjiang and its relationship with meteorological factors, the test used sex attractant trapping method in field during 2010- 2012. The results showed that Leguminivora glycinivorella started in late July and reached the peak in early August to mid-August, ended at the end of August, lasting for 30 days. Population dynamics of Leguminivora glycinivorella was significantly positive related to the average temperature in years with less rainfall. Moderate rainfall could cause high air humidity, which led to increasing amount of moth, but heavy rainfall was unfavorable for Leguminivora glycinivorella pupation and adult unearthed. In Mudanjiang, daily average temperature at 21- 24℃was optimum for the occurrence of Leguminivora glycinivorella, and constant high temperature and drought weather was not conducive to adult occurrence. Therefore, temperature and precipitation were important factors affecting the occurrence of Leguminivora glycinivorella.
