| Abstract |
Host range and seasonal abundance of the corn leaf aphid Rhopaiosiphum maidis Fitch (CLA) was estimated at Zagazig district, Sharkia Governorate during two continues years (2001/2002 and 2002/2003).
Rhopalosiphum maidis Fitch found infesting 21 plant species two as grain crops (maize presented and wheat), 5species as foliage crops (millet, broom corn, soccharia, maize and Johnson grass) and 14 species of weeds[ jungle rice, barnyard grass, rabbit grass, green fox tail, little seed canary grass, wild oat, sugar can (Solitary plants), common reed, dog grass, annual bluegrass, rabbit foot grass, purple nut sedge and mosa, (Solitary plants)]. The grain crop plants (Z. mays) harbored relatively the highest numbers (presented with 24.46% of the total number of aphid) followed by foliage plants (especially, Sorghum vulgure presented with 22.21%) and weeds.
Seasonal abundance of Rh. Maidis population on the different hosts indicated that, population density of CLA on foliage crop and weed plants was raised before and after suitable growing periods of maize and wheat plants. The infestation of Rh.maidis started on the weed plants Echinochloa colonum Link, Polypogon monspeliensis Desf and Cyperus rotundus L.) from end November till mid or end January then aphid migrate to wheat and maize which cultivated as foliage crops the infestation continuous reaching to mid April and then migrate to early summer plantation maize (grain crop), also the aphids migrate from Bachiaria eruciformis Grisb and Setaria spp. To maize (grain and foliage crops) and to soccharia (foliage crop).
