Abstract: The major insect pests of economic importance on vegetable crops and their biology were investigated during three successive seasons (1997-1999). Twelve species belonging to eight different families and four different orders Hemiptera, Homoptera, Thysanoptera and Lepidoptera were recorded on different host plants. Homopterous and Lepidopterous species are the most abundant, representing 42 and 33% , respectively, followed by Hemipterous (17%) and Thysanoptera (8%) orders. Results showed the importance of many species of insects as pests of vegetable crops in the area. Most of them are known only to cause economic damage in the Mediterranean basin.
