[Biotypes of insect pests and their genetic mechanisms]
Acta Entomologica Sinica 47 (5), 670-678
Abstract: The biotypes of several important pests including Mayetiola destructor, Schizaphis graminum, Nilaparvata lugens, Orseolia oryzae and Bemisia tabaci on agricultural crops were introduced, then the applications of molecular markers to the research on biotypes were generalized. The present paper stressed the reviews on inheritance and variance of biotypes of the above pests. Biotypes of M. destructor, S. graminum and O. oryzae were conditioned by major genes, and specific pest virulence-host plant resistance interactions followed a gene-for-gene relationship. The virulence of N. lugens was under polygenic control and was a quantitative character. The genetic nature of B. tabaci was less clear. Finally, some questions, such as the relationships between the genetic divergence and the virulence of biotypes were discussed.
