Abstract
Evaluation the efficiency of Chrysoperla carnea second instar larvae , of predator were released at three different rates (3, 5 and 7 larvae / plant) for suppression aphids the cotton – melon aphid, Aphis gossypii Glover and the green peach aphid, Myzus persicae Sulzer as well as nymphs and pupae of Bemisia tabaci Genn. on cantaloupe ( Cucumis melo L.) plants (the local cantaloupe variety, Arafa) .The experiment was conducted under semi-field conditions during early summer plantation season of 2010 . The promising and best results were obtained after 21 days from releasing date at rate of 5 predatory larvae / plant, however, these larvae reduced populations of aphids and whitefly by 73.9 and 83.07%, respectively.
