| Abstract | ||
| Eggplant (Solanum melanogena L.) is an important vegetable crop that is attacked by many insect pests; therefore, this research was conducted to study the seasonal abundance of eggplant insect pests under open field conditions. The results showed that the eggplant crop was exposed to many insect pests, the most important of which are: onion thrips, Thrips tabaci L., the cotton and tomato whitefly Bemisia tabaci (Genn.), leafhoppers (Empoasca spp.), cotton aphid, Aphis gossypii (Glover), green peach, Myzus persicae, leafminer, Liriomyza sativae (Blanchard) and the cotton mealybug. Phenacococcus solenopsis tinsley. The highest average number of insects attacking eggplant leaves was Thrips tabaci L (120.4 individuals), followed by Bemisia tabaci (48.9 individuals), while the least numerous insect was P. solenopsis (6.8 individuals). The cotton thrips Thrips tabaci and L. sativae recorded one infestation peak, while Bemisia tabaci, Empoasca spp., and Phenacoccus solenopsis recorded two infection peaks, and finally, Aphis spp. recorded three peaks of infestation. | ||
