The chromosome number and sex-determination of 15 actinotrichid species belonging to Eriophyidae, Tenuipalpidae, Tetranychidae, Tydeidae and Epidermoptidae were determined. The chromosomes of most species examined are few in number and roughly similar in size, shape and behaviour. It is believed that all species have holokinetic chromosomes. Haplo-diploidy was shown to be the mechanism of sex-determination in the Eriophyidae, since all 8 species examined were found to have eggs with n = 2 and 2n = 4 chromosomes. Myialges pari Fain is the first psoroptid species examined on karyotype. The occurrence of eggs with n = 8 and 2n = 16 chromosomes is evidence for the existence of haplo-diploidy in the order of the Psoroptina. © 1983 Taylor & Francis Group, LLC.
