Effect of virulence genes complementary to the effective resistance genes in sorghum on fitness of the greenbug, Schizaphis graminum Rondani (Homoptera, Aphididae)

Analysis of the greenbug (Schizaphis graminum Rond.) -- sorghum interaction system confirmed the hypothesis that rare insect virulence was related to reduced fitness. Greenbug clones from the Krasnodar population virulent to resistance genes Sgr5 and Sgr6 revealed lower fecundity in comparison with...

Description
Summary:Analysis of the greenbug (Schizaphis graminum Rond.) -- sorghum interaction system confirmed the hypothesis that rare insect virulence was related to reduced fitness. Greenbug clones from the Krasnodar population virulent to resistance genes Sgr5 and Sgr6 revealed lower fecundity in comparison with avirulent ones and were replaced in model populations during reproduction on a susceptible sorghum line. The main role of aphid fecundity was shown to provide higher fitness, reducing the frequency of virulent clones in natural populations.
