Genetic diversity in natural populations of Greenbug, Schizaphis graminum (Rondani) /

Insects often develop new virulent biotypes. It is estimated that 50% of recognized insect biotypes on agricultural crops are of the family Aphididae. Development of biotypes in greenbug, Schizaphis graminum (Rondani), is well documented. Characterizing the extent and distribution of genetic vari...
