通过分析15年来尤其是1992年以来临汾地区气象资料和棉铃虫系统调查数据，探讨了该区温度、降水、湿度等气象要素对棉铃虫发生消长的影响。结果认为，4－6月份温度是影响越冬代和1代发生期、2代卵盛期的主要因子，此期温度高的年份，棉铃虫发生早；降水量和雨日数主要作用于2，3，4代发生量，在各代发生期内，雨量大、雨日多、分布匀、空气湿度高，棉铃虫大发生。这为县、乡、村发布棉铃虫短期预报，制定防治方案提供了理论依据。
By analyzing the survey data of meteorological data and cotton bollworm system in Linfen since 15 years, this paper discussed the effects of meteorological factors such as temperature, precipitation and humidity on the growth and development of cotton bollworm. The results showed that the temperature in April-June was the main factor affecting the overwintering and first generation, the second generation of egg blooming, the high temperature in this period, the early occurrence of cotton bollworm; the main effect of precipitation and rain days on 2,3 In the fourth generation, the occurrence of large-scale cotton bollworm occurred during the occurrence of each generation with large amount of rainfall, rainy days and even distribution of air humidity. This provides a theoretical basis for the county, township and village to issue short-term forecast of bollworm and formulate prevention and control programs.
