Amino acid analyses of haemolymph of Glossina morsitans morsitans (Westwood).
نویسندگان
چکیده
Haemolymph from pupae and adult G. morsitans was analysed for its content of free amino acids. Of the twenty-one amino acids identified proline occurred in the greatest concentration in the 3 stages tested. Substantial amounts of taurine, glutamine, glutamic acid, alanine, tyrosine and arginine were also measured. There was considerable variation in the content of amino acids in the 3 stages of development of the tsetse fly.

Isolation and properties of 600-kDa and 23-kDa haemolymph proteins from the tsetse fly, Glossina morsitans: their possible role as biological insecticides.
The haemolymph of the tsetse fly, Glossina morsitans morsitans, contains a high (lipophorin) and a low molecular weight protein of high densities, 1.11 and 1.29 g/ml, respectively. The purification of the proteins was achieved by a combination of density gradient ultracentrifugation and reported gel permeation chromatography. The lipophorin is of high molecular weight (M(r) integral of 600,000)...

Reproductive anomalies associated with the tsetse DNA virus infection in the female tsetse hosts, Glossina morsitans centralis Machado and Glossina morsitans morsitans Westwood, inoculated with the virus during the 3rd instar larval stage were studied and the data compared to those obtained from the control females injected with sterile physiological saline. Virus infected flies had significant...

Following injection of U-14C threonine into the haemolymph of adult female Glossina morsitans during late pregnancy, radioactivity was detected in the postparturient female and in its offspring, in threonine, lipids, and a range of non-essential amino acids. The level of radioactivity recovered from the larva was higher than that remaining in the injected adult, and the radioactivity recovered ...
متن کاملDefence reactions of Glossina morsitans morsitans against different species of bacteria and Trypanosoma brucei brucei.
Tsetse flies, Glossina morsitans morsitans, fed on rats infected with Trypanosoma brucei brucei showed wide fluctuations in total and differential haemocyte counts. Similar fluctuations occurred in controls fed on non-infected rats and also between the two groups without showing any difference which could be attributed to the infection. Trypanosome infection of the tsetse haemocoel occurred in ...
