草地贪夜蛾在江苏地区的发生特征及主要影响因素
Study on the spatiotemporal characteristics and main influencing factors of spodoptera frugiperda in Jiangsu Province
摘要
Abstract
Based on the monitoring data of spodoptera frugiperda in Jiangsu Province from 2019 to 2022,the temporal and spatial occurrence characteristics of spodoptera frugiperda and its main influencing factors were analyzed.Results show that the spodoptera frugiperda was mainly concentrated in the south of the Huaihe River,and Yancheng and Nantong were the areas with serious occurrence of spodoptera frugiperda.The year with the largest recurrence area of the spodoptera frugiperda was 2020 in the past four years.It mainly harms maize in Jiangsu,including spring maize,conventional summer maize and late sowing summer maize.The late sowing summer maize had the most serious occurrence,most of which occurred in a concentrated and continuous manner.The maximum number of insect pests per hundred plants ranged from 54.7 to 125.6,and the maximum percentage of damaged plants was above 93.0％.The migration period of adults to Jiangsu was mainly from May to September,of which June to July was the peak period for adults to migrate.The serious occurrence area and migration peak period of the spodoptera frugiperda are closely related to corn planting,migration rules,atmospheric circulation and meteorological conditions.The research can provide scientific basis for formulating accurate prevention and control strategies and monitoring and early warning.关键词
