The Karyotype of the parasitoid Chelonus insularis cresson (Hymenoptera, braconidae, cheloninae).

The Karyotype of chelonus insularis (Hymenoptera, Braconidae Cheloninae) is described. The males show an haploid number of seven chromosomes and the females a diploid number of fourteen chromosomes, confirming haplo-diploid sex determination. Comparisons of these results with karyotypes of other spe...

Sumario:The Karyotype of chelonus insularis (Hymenoptera, Braconidae Cheloninae) is described. The males show an haploid number of seven chromosomes and the females a diploid number of fourteen chromosomes, confirming haplo-diploid sex determination. Comparisons of these results with karyotypes of other species of the same family were done and a possible mechanism involved in the karyotype evolution of this species is discussed.
