Abstract | ||||
Survey study was carried out on soybean (Glycine max L.) plants in the field at Giza region, throughout two growing seasons 2001/2002. Results revealed the occurrence of three aphid species: the cowpea aphid, Aphis craccivora (Koch.), the green peach aphid, Myzus persicae (Sulz.) and the cotton aphid, Aphis gossypii (Glov.). A. craccivora recorded the highest incidence, followed by M. persicae and A. gossypii.. Eleven different weed plant species occurred within the soybean field five of them hosted aphids. Only three aphid species were associated with the dominant weed species; M. persicae on Convolvulus arvensis ,Amaranthus spp. ,Euphorbia spp. ,Solanum nigrum and P. oleraceae. A. craccivora occurred on Euphorbia spp. and Portulaca oleraceae,while A. gossypii occurred on P. oleraceae and S. nigrum . | ||||
