Nowadays several viruses are known as pathogens able to trigger the dwarf syndrome of these viruses. Under natural conditions, the leafhopper species are detected as natural vectors. The infected plants fall behind in their development. Leafhoppers were collected from vegetable crops; potato, Solanum tuberosum (L.), eggplant, Solanum melongena (L.), pepper, Capsicum annuum (L) zucchini, Cucurbita pepo okra, Abelmoschus esculentus (L.), as well as from agronomic crops (alfalfa, Medicago sativa (L.) maize, Zea mays (L.) and rice, Oryza sativa (L.) in North and south Egypt. The leafhopper species collected during 2013 season were identified using only the morphological methods. In vegetable crops, the leafhopper species collected were more than in the agronomic crops; on the other hand the leafhopper diversity in agronomic crops was greater than those in vegetable crops. Seven leafhopper species have been identified; the dominant species is Empoasca decipiens (82.5%), followed by Balclutha incisa and Sogatella vibix. In zucchini field, there was the highest leafhoppers (20%); followed by 15.3% in each of potato and pepper fields, while rice and alfalfa had the lowest leafhopper percents 7 and 6%, receptively. The present results provided the current knowledge and diversity of Cicadellidae populations in various crops in Egypt, which could be supportive to make a future management strategy for such insect.
