Chromosome Numbers of some Psocid Genera (Psocoptera)

Article metrics

Abstract

PSOCID chromosomes have been studied by Boring1, who has described in detail the behaviour of the chromosomes of Cerastipsocus venosus (Kolbe) during meiosis in spermatogenesis. The chromosome number for this species of the family Psocidae was established as 2n = 16 + 1 in the male. We have examined testis squash preparations of a number of Hong Kong species, both in order to verify Boring's description and interpretation of the mechanism of sex determination, and also to establish the chromosome numbers of representatives of as many genera and families as possible.
