Title: Mechanism of polyploidization in the Malpighian tubes of blood-sucking reduviid hemipterans
Author: Mello, M.L.S.
Abstract: [No abstract available]
The possibility of polyploidy arising by nuclear fusion in the Malphighian tubes of reduviid hemipterans was investigated by counting the number of nuclei of the epithelial cells in organs of adults and early and fully-grown nymphae of fully-nourished Panstrongylus megistus Burmeister. Constancy in number of nuclei was demonstrated, which indicates that nuclear fusion does not normally play a part in the olyploidization mechanism of these Malpighian tube nuclei. Polyploidy is therefore assumed to be attained in this case by endomitosis
