Chromosomes of parasitic wasps from Alysiinae subfamily (Hymenoptera, Braconidae).

摘要

Karyotypes of 2 braconid species of the Alysiinae subfamily, Alysia manducator (n = 11, 2n = 22) and Chorebus petiolatus (2n = 32) are described for the first time. Relatively high numbers of chromosomes in most Alysiinae (n = 16-17) are supposed tobe plesiomorphic for this group, as well as for braconids in general. The low number of chromosomes in A. manducator should be considered as its autopomorphy.
