Title: Change With Age Of Feulgen-dna Values In The Blood-sucking Insect, Triatoma Infestans Klug
Author: Mello M.L.S.

Abstract: Feulgen-DNA values were evaluated cytophotometrically in the Malpighian tubes of T. infestans at the nymphal, adult and ageing life periods. In all cases the total nuclear Feulgen-DNA contents were found to be distributed within the 32C and 64C classes. However, part of the Feulgen-DNA values is shifted to lower intervals in ageing insects, as compared with nymphal and adult individuals, promoted by decrease in Feulgen-DNA values of the euchromatins. Changed response to Feulgen reaction due to some aging-induced alteration in DNP complexes, and/or breaks and loss of DNA in the euchromatins, as part of the senescence process, are ascribed as responsible for such phenomena.
