Abstract

The influence of constant and variable temperatures on biology of M. persicae in sweet pepper was evaluated. The nymphs were individualized on pepper leaf discs and maintained in Petri dishes at constant temperatures of 15, 20, 25, and 30ºC. In greenhouse the temperature was variable with an average of 24.9ºC and the nymphs were kept in appropriate cages and fixed in sweet pepper leaves. The experimental design was completely randomized with 45 and 30 replicates for the laboratory and greenhouse assays, respectively. It was evidenced that constant temperatures of 20 and 25ºC were more favorable to M. persicae, decreasing the biological cycle and increasing the fecundity, than the oscillatory temperatures in the greenhouse.
