The chromosome complement of the mosquito Culiseta longiareolata (2n=6) reveals distinguishable centromeric regions and one telomere of the Y chromosome by using light-induced differentiation and autoradiographic techniques in mitotic and premeiotic interphase nuclei. The localization of these cytological markers and their spatial relationships appear to be very similar in the two types of nuclei and suggest an interphase arrangement where centromeric regions are clustered together in a chromocenter like structure, close to the nuclear membrane, with the telomeres lying on the opposite pole of the nucleus.

Abstract
The chromosome complement of the mosquito Culiseta longiareolata (2n=6) reveals distinguishable centromeric regions and one telomere of the Y chromosome by using light-induced differentiation and autoradiographic techniques in mitotic and premeiotic interphase nuclei. The localization of these cytological markers and their spatial relationships appear to be very similar in the two types of nuclei and suggest an interphase arrangement where centromeric regions are clustered together in a chromocenter like structure, close to the nuclear membrane, with the telomeres lying on the opposite pole of the nucleus.
