Abstract
The green two-spotted spider mite Tetranychus urticae Koch and the red spider mite T. cucurbitacearum (Sayed) were
subjected to study to shed lights on their identity based on state of reproductive compatibility. However cross breeding
produced fertile and normal hybrids for Fl and F2 in relation to egg laying capacity and sex ratio of the offspring.
Also inheritance of female offspring color was maternaL
