Selection and quality control of the laboratory populations of Harmonia dimidiata Fabr. and H. yedo-ensis Takiz
We have implemented a quality control and stabilizing selection in laboratory populations of Harmonia yedoensis Takiz and H. dimidiata Fabr. Population of H. dimidiata maintains an acceptable rate. The state laboratory population of H. yedoensis can be considered satisfactory. The increased level of early lethal reduces the reproduction this culture, but does not prevent its mass reproduction.
