| The population fluctuation of three major sap sucking insect pests thrips. Thrips tabaci Lind. (Thripidae: Thysanoptera) aphids, Aphis gossypii Glov. (Aphididae : Homoptera) and whitefly, Bemisia tabaci Genn. (Aleyrodidae: Homoptera) on cantaloupe summer plantations was studied at EI-Manawat village, Giza Governorate during 1995 and 1996 seasons. Cantaloupe plants are subject to infestation with the three pests from germination till harvest (May-July). Thrips and aphid infestations were noticeably high from early may until mid-June, then relatively lower until harvest by late July. Whitefly infestation increased progressively from mid-June till the end of July. Three peaks of thrips were recorded by late may-early June. the 2 nd half of June and the 2 nd- 3 rd week of July. Two peaks of aphid infestation took place during the 4 th week of May and the 3rd week of July. Whitefly peaks occurred during the 4th week of May, 3rd week of June and 3rd week of July. | ||||
