摘要
为进一步了解山东烟台地区花生田主要害虫发生种类和发生动态,2017-2020 年,利用色板诱集法对山东烟台地区花生田间害虫进行系统监测.结果表明,烟台地区花生田地上害虫优势种群主要有西花蓟马、花生蚜虫、叶蝉、潜蝇、虻科.西花蓟马多暴发于7、8月,虫口数量显著高于其他月份.西花蓟马虫口密度与平均气温、平均地温、日照时间呈正相关,其中与平均气温、平均地温呈显著相关;与平均相对湿度、降雨、风速呈负相关但不显著.
Abstract
In order to further understand the species and occurrence dynamics of major pests in peanut fields in Yantai area of Shandong Prov-ince,from 2017 to 2020,the pests in peanut fields in Yantai area of Shandong Province were systematically monitored by color plate trapping method.The results showed that the dominant populations of pests in peanut fields in Yantai area were mainly Frankliniella occidentalis,pea-nut aphids,leafhoppers,Liriomyza and Tabanid.F.occidentalis mostly broke out in July and August,and the number of insects was higher than that in other months.The population density of F.occidentalis was positively correlated with average temperature,average ground temper-ature and sunshine time,and was significantly correlated with average temperature and average ground temperature.It was negatively correla-ted with average relative humidity,rainfall and wind speed,but not significant.
