Autor: W. D. Guthrie, J. W. Bing, F. F. Dicke

Publikováno v: Journal of Economic Entomology. 85:1476-1479

Ten inbred maize, Zea mays L., lines-A619, A632, B37, B68, B73, B96 (41:2504B), C103, Mo17, Oh45, and W153R-and diallel crosses (45 single crosses) were analyzed to determine the type of gene action involved in resistance to the com leaf aphid, Rhopa

Stylet Penetration and Feeding Sites of Rhopalosiphum maidis (Homoptera: Aphididae) on Two Growth Stages of Maize

Autor: John J. Obrycki, J. W. Bing, W. D. Guthrie, M. G. Novak

Publikováno v: Annals of the Entomological Society of America. 84:549-554

Stylet penetration and feeding sites of Rhopalosiphum maidis (Fitch) were observed on the seedling stage (Plumule to V1) and the late whorl stage of (V15) maize inbred B96 ( Zea mays L.). Fifty-seven percent of R. maidis stylets entered plants in the

Autor: J. W. Bing, W. D. Guthrie, F. F. Dicke, J. J. Obrycki

Publikováno v: Journal of Economic Entomology. 84:625-632

Five maize ( Zea mays L.) inbred lines (B37, B73, C103, Mo17, and B96 [41: 2504B]) were infested with alate corn leaf aphids, Rhopalosiphum maidis (Fitch), in the greenhouse, and then transplanted to the field to quantify the effects of seedling feed

Relation of Corn Leaf Aphid (Homoptera: Aphididae) Colonization to DIMBOA Content in Maize Inbred Lines

Autor: W. D. Guthrie, J. W. Bing, J. J. Obryckp, F. F. Dicke

Publikováno v: Journal of Economic Entomology. 83:1626-1632

Five inbred maize ( Zea mays L.) lines (B37, B73, C103, Mo17, and 41:2504B) were evaluated from emergence to the eight-leaf stage for corn leaf aphid ( Rhopalosiphum maidis (Fitch)) colonization. Concentration of 2,4-dihydroxy-7-methoxyl-l,4-benzoxaz

Genetics of Resistance in Maize to a Complex of Three Species of Thrips (Thysanoptera: Thripidae)

Autor: F. F. Dicke, W. D. Guthrie, J. W. Bing

Publikováno v: Journal of Economic Entomology. 83:621-624

During summer 1988, a heavy infestation of Thrips, Anaphothrips obscurus (Mueller), Frankliniella fusca (Hinds), and F. tenuicomis (Uzel) occurred on maize, Zea mays L., allowing for evaluation of resistance in 10 inbred maize lines. Thrips populatio

Generation Mean Analysis for Resistance in Maize to the Corn Leaf Aphid (Homoptera: Aphididae)

Autor: J. W. Bing, W. D. Guthrie

Publikováno v: Journal of Economic Entomology. 84:1080-1082

Corn leaf aphids [Rhopalosiphum maidis (Fitch)] can be a serious pest of maize, Zea mays L. Because very little is known about the genetics of corn leaf aphid resistance in maize, a generation mean analysis was conducted on nine generations of maize
