Conteúdo: | The mechanisms of increase, persistence and decrease of resistance of citrus red mite ot acaricides were studied population genetically. In the expeiments on the fitness, reproduction rate, viabaility and oviposition rate were compared in acarocode resistant (R) and susceptible (S) strains of the same origin, and the changes of susceptibility to acaricides in the mixed populations of R and S strains were tested. The reproduction rate in dicofol-R strain was lower than that in the S strain under either favorable (25 degreeC) or unfavorable for reproduction of mites. This was mainly caused by lower egg production in the resistant mites. From the experimental data of the dicofol susceptibility of the mixed population of R and S strains, it was also shown that theresistant mites (RR) had lower value of fitness than the susceptible ones (SS,RR) under an acaricide-free environment. The reproduction rate in benzomate-R strain was almost equal that in the S strain under either favorable or unfavorable conditions. There were no significant differences in fitness between benzomate-resistant mites (RR, RS) and susceptible ones (SS) under and acaricides-free environment.
