Abstract

Hemisarcoptes coccophagus Meyer (Acariformes: Astigmata: Hemisarcoptidae) is a parasite of armored scale insects (Homoptera: Diaspididae). This mite can adjust the sex ratio of its progeny. We found that H. coccophagus has a diploid karyotype with 2n=14 in both sexes; the sex determining mechanism is either diplo-diploidy or parahaploidy. This provides one of the few examples, and the first in the Acariformes, of a non-arrhenotokous arthropod genetic system with the ability of facultative sex ratio adjustment.
