| 摘 要： | 为明确大豆食心虫Leguminivora glycinivorella (Matsumura)田间自然种群动态变化规律，建立基于性诱监
测田间成虫数量的大豆食心虫防治指标，采用性诱剂诱捕法对田间大豆食心虫成虫数量动态进行系统监测，同时
结合田间豆荚落卵量的调查，采用回归分析方法拟合田间大豆食心虫成虫发生量与大豆百荚卵量的关系，进而通
过卵量指标确定成虫数量指标。结果表明，在吉林长春大豆食心虫成虫发生期主要集中于8上中旬，发生数量动态
在年度之间存在差异；成虫数量与百荚卵量之间显著相关，回归方程为y=0.946lnx+ 0.303（R²= 0.939，p =0.001），据
此建立了基于性诱剂监测田间大豆食心虫数量确定成虫防治指标的方法，为开展大豆食心虫智能化预测预警技术
研究提供了理论依据。

| Abstract: | The aim was to determine the natural population dynamics of soybean pod borers (SPB) Legumenivo⁃
ra glycinivorella (Matsumura) adult in field, and to establishe control index for SPB adult monitoring based on sexu⁃
al trap. In this study, sex attractant trapping method was used to systematically monitor the population dynamics of
SPB in field, and combined with the investigation of eggs number in field pods. The regression analysis method was
used to fit the relationship between occurrence of SPB adults and quantity of soybean pod eggs, and then the quanti⁃
ty index of adults was determined by egg quantity index. Results showed that the occurrence period of SPB adults in
Changchun, Jilin was mainly concentrated in the early and middle of August, and the number of occurrences varied
from year to year. There is a significant correlation between the number of adult insects and the amount of eggs per
hundred pods. The regression equation is y = 0.946lnx + 0.303, (R2 = 0.939, p = 0.001). Based on this, a method for
determining adult control index based on monitoring the number of SPB in field was established. It provided a theo⁃
retical basis for predicting and early warning technology of SPB. |
