Karyotypic details were studied in males of six beetle species from three families, viz. Tenebrionidae: Dailognatha pumila Bdy. (2n=20, n male= 9+Xyp), Pachyscelis musiva Menetr. (2n=18, n male= 8+Xyp), Pimelia capito Kryn. (2n = 18, n male= 8+Xyp); Cerambycidae: Agapanthia walteri Reitt. (2n=20, n male = 9+Xyp), Agapanthia korostelevi Danilevsky (2n=20, n male = 9 + Xyp); Curculionidae: Phyllobius caucasicus Stierl. (2n = 22, n male=10+Xyp). The chromosome number and sex determining system of all beetle species are described for the first time. Evolutionary trends in karyotypes of the studied beetle groups are briefly discussed.

Karyological studies were carried out on three Armenian weevil species from the subfamily Cleoninae. The following chromosome numbers were found in individual species: 2n = 38, n% = 18+Xyp in Menecleonus anxius (Gyllenhal, 1824), 2n=40, n% = 19+Xyp in Conorhynchus nigrivittis (Pallas, 1781) and 2n = 44, n% =21+Xyp in Lixus iridis Olivier, 1807. The heterochromosomes of all the examined species form, in the first meiotic metaphase, a typical parachute bivalent.
