Abstract

The present experiment was conducted in Zefta, Gharbia governorate to examine the influence of fertilization levels on the population density of the different leafhoppers and planthoppers attacking eggplant crop during the two successive seasons (2017and 2018). The potassium fertilization levels of zero kg/fed. to 25, 50, and 75 kg/fed. attracted the highest average number of the leafhopper and planthopper species during the two seasons. The present study indicated that increasing potassium fertilization rates from zero kg/fed. to 25, 50 and 75 kg/fed. led to a decline in the average number of the tested insect pests during the two years with significant differences. The potassium fertilization of 75 kg/fed. attracted the lowest percentage of occurrence of the tested insect pests and presented by 13.6 and 15.3 % during the two seasons 2017 and 2018, respectively.
