In arrhenotokous arthropods, males arise from unfertilized eggs. Hence, by controlling the fertilization process mothers can adjust the sex ratio in their offspring. In pseudo-arrhenotokous phytoseiid mites, however, males are haploid, but arise from fertilized eggs. The haploid state is achieved through elimination of the paternal chromosome set during embryonic development. It is shown in this paper that phytoseiid females can control the sex ratio in their offspring and that this control… CONTINUE READING
