Twenty-three Hessian fly, Mayetiola destructor (Say), populations collected in the southeastern (Alabama and Mississippi), midwestern (Indiana), and northwestern (Idaho and Washington) United States from 1995 to 1999 were evaluated for biotype composition based on response to Hessian fly resistance genes H3, H5, H6, and H7H8 in wheat, Triticum aestivum L. Biotypes L and O, combined, made up at least 60% of all Alabama populations. Biotype L was predominant in the northern third of Alabama and… CONTINUE READING
