Abstract
potato (Solanum tuberosum L.) holds a prominent position in Egypt's agricultural landscape, serving as a vital staple crop and a cornerstone of the nation's economy. The present work was planned to survey and evaluate population density of insects of Potato plant for two growing seasons 2022/2023 and 2023/2024, at Dakhlia (Aljamalih region) and Damietta (Tftish alsarw region) Governorates and effect of to environmental factors (mean temperature and relative humidity) on population density of insects. Four insect species belong to Order Hemiptera (Bemisia tabaci (Gennandius), Myzus persicaee (Sulker), Empoasca descipiens, and Aphis gossypii (Glover) and three insect species belong to Order Lepidoptera (Phthorimaea operculella (Zeller); Tuta absoluta; and Agrotis ipsilon) were surveyed and identified from collected samples. Collected insects were higher population and percentage of frequency in Tftish alsarw region, Damietta Governorate than in Aljamalih region. Dakhlia Governorate, the population and frequency (%) of insects were higher through 2022/2023 than 2023/2024 growing seasons. Meanwhile, Empoasca descipiens insect was the most population and percentage of frequency compared with other insects, following by Bemisia tabaci (Gennandius) insect and Agrotis ipsilon insect was the lowest population and percentage of frequency.
