title: Notes on midgut cell nuclear coats in various tsetse species.
abstract: Coats were found on the midgut cell nuclei of G.m. morsitans, G. austeni, G. tachinoides, G. f. fuscipes and G. p. palpalis. No coat was found in G. p. gambiensis. The coats were of differing ultrastructural design and of different dimensions in each species. The appearance of the coat seems to be linked to the physiological train of events following the bloodmeal rather than to novel events such as viral or protozoal infection. The timing of its appearance varied among the different species examined.
