Abstract
The current investigation aimed to assess the incidence and the population fluctuations of the main insect pests and associated predators on sugar beet plants and as well to determine their relation with temperature, relative humidity, precipitation, and mean numbers of leaves per plant at El-Hosinia district, Sharkia Governorate,Egypt during the two successive seasons of 2021/22 and 2022/23. The results revealed that Empoasca decipiens (Paoli) was the most dominant insect pest species constituting 51.72% of the general total numbers of pests. Moreover, it followed by Cicadulina chinai (Gauri), Pegomyia mixta (Vill.), and Myzus persicae (Sulzer), recording 34.61, 11.57, and 2.10%. The major predaceous species were Chrysoperla carnea (Steph.) (61.45%), and Coccinella undecimpunctata L. (38.55%). Statistical analysis proved that the combined effect of the tested ecological factors on the population activity of insect species was ranged from 36.47 to 64.14% in the first season and 56.76 and 92.62% in the second one. These findings would provide valuable knowledge for the researchers, farmers, and breeders of sugar beet in Egypt.
