害虫迁飞规律的揭示为害虫的预测预报工作开拓了新的探索领域,许多昆虫学工作者和气象工作者致力于气象因素与迁飞关系的研究,进行害虫长期数量预报。赵圣菊(1984)建立了粘虫一代发生区的发生期、发生量的长期预报模式.宋祥燕(1983)分析了迁飞的气象条件,作了稻纵卷叶螟迁飞期、迁飞量的预报尝试。程极益等(1985)用PC-1500微型机以3—5月的气象资料作为参量预报稻纵卷叶螟的发生程度。我们为了预报郑州地区第三代稻纵卷叶螟成虫迁入数量,用IBM电子计算机分析了1978—1985年的气象资料和虫情资料,筛选了主要生态因素,组建了预报方程。材料和方法稻纵卷叶螟(Cnaphalocrocis medinalis)
The pest shedding rules revealed a new field of exploration for pest forecasting. Many entomological workers and meteorologists devoted themselves to the study of the relationship between meteorological factors and migration and long-term pest population forecast. Zhao Shengju (1984) established a long-term prediction model for the occurrence and occurrence of the eradicating area of Mythimna separata. Song Xiangyan (1983) analyzed the meteorological conditions of the migration and predicted the migration and migration of the rice leafroller try. Cheng Yi-yi et al. (1985) used the PC-1500 microcomputer to predict the occurrence of rice leaf roller over the March-May meteorological data. In order to forecast the number of adults of the third generation of C. medinalis in Zhengzhou area, we used the IBM computer to analyze the meteorological data and insect information from 1978 to 1985, screened the main ecological factors and established the forecasting equations.
