Abstract

In the literature many researchers dedicated to studying the importance and implications of aspects of genetic variability in populations of insects used in biological control programs. However, few studies assess the influence of this factor in field performance of the insects used in biological control programs. The knowledge of the implications of genetic variability in populations of natural enemies, especially parasitoids, is of vital importance for the optimization of biological control programs. Thus, this proposal, which is a partnership between the University of São Paulo and the University of Califórnia-Riverside/EUA, aims to determine the influence of genetic variation and adaptations to the mass rearing Trichogramma pretiosum (Riley, 1879), in his performance in field conditions. Three trials will be held: one to determine the relative performance of Trichogramma pretiosum strains of "inbred" in the field, a second experiment to determine the minimum generations genetically variable populations can be maintained under conditions of mass production to decline their performance, and a third trial that will evaluate the performance of the strains in the laboratory.
