Abstract
Field experiments were conducted to estimate population density of six Hemiptereous insect species thatt attacking sweet pea plants during two winter seasons of 2018 and 2019 at Dekernce region, Dakhlia Governorate. As well, to determine the impact of temperature and relative humidity on their populations. The results showed that, Myzus persica (Zeller) had two peaks during winter plantation that was recorded during 26th of November of both seasons. Data revealed that Aphis carccivora (Koch) and Acrythosiphn pisum (Koch) had only one peak for each during each season of plantation. Counts showed that Empoasca descipiens had one peak in the winter plantation during 17th of March. Three peaks during winter seasons plantations were recorded for Empoasca decedens. On the other hand, Nezara viridula had two population peaks in each of the two sweet pea seasons. The correlation between population density of the recorded insects and each of temperature or relative humidity had various degrees of significance that differed from positive to negative and from non-significant to highly significant.
