Survey of arthropods associated with cucurbit crops during 2011and 2012 growing seasons at the New valley in Egypt indicated the existence of 28 insect species belong to 25 genera under 20 families of 9 orders. In addition to the two spotted spider mite, Tetranychus urticae Koch and some unidentified species of the true spiders belong to family, Phalangidae. The important piercing-sucking arthropod pests were the black melon bug, Coridius (Aspongopus) viduatus F.; the melon aphid, Aphis gossypii Glover; the tomato whitefly Bemisia tabaci (Genn.) and T. urticae. The cucurbit fruit flies, Bactrocera zonata(Saunders), Dacus ciliatus Loew, D. frontalis  (Becker) and Dacus sp.( Tephritidae: Diptera ) and Baris granulipennis  Tour.(Curculionidae: Coleopatra ) were recorded as pests on the fruits of cucurbit plants in the New Valley. The common associated natural enemies inhabiting cucurbit fields were, Coccinella septempunctata L.; Chrysoperla carnea Steph., and C. undecimpuctata aegyptiaca Reiche. Ooencyrtus sp. was recorded as a key egg parasitoid of the black melon bug.
