| Abstract | ||||
| These studies were carried out in Kafr-Saad district, Damietta Governorate during 2022 season on four vegetable crops, (cucumber, cowpea, tomato and sweet potato). The present study showed that the different vegetables were attacked by seven piercing-sucking insect species i.e.: Aphis gossypii, Myzus persicae, Bemisia tabaci, Thrips tabaci, Empoasca sp., Phenacoccus solenopsisand Nezara viridula belonging to two insect orders: Thysanoptera and Hemiptera. Five insect species were recorded on each of the investigated crops, while the green peach aphid, Myzus persicae recorded only on cucumber plants, the cotton thrips, Thrips tabaci was not recorded on sweet potato plants. The most attracted host plants for the insect species was cucumber followed by cowpea and tomato, whereas sweet potato ranked the last category and represented by 282.8, 18.6, 10.5 and 5.6 individuals /sample, on cucumber, cowpea, tomato and sweet potato respectively. The cotton aphid, Aphis gossypii was the predominant species on cucumber, cowpea and tomato and represented by 890.1, 47.8 and 29.7 Aphids /sample, respectively with significant differences. Meanwhile, the green stink bug, Nezara viridula occupied the last category on the three vegetable host plants and represented by 1.8, 3.1 and 3.4 individuals/sample, respectively. On the other hand, the cotton mealybug, Phenacoccus solenopsis recorded the highest average number on sweet potato followed by the leafhoppers, Empoasca sp. and represented by 7.4 and 4.4 individuals /sample, respectively. | ||||
