structural modulations in the tsetse fly milk gland during a pregnancy cycle.gross ultrastructural and histochemical details of the integumental milk glands of the tsetse fly glossina morsitans have been examined during the pregnancy cycle. structural evidence for protein secretion is found between days 3-8 of the nine-day cycle: termination of activity is completed on the day of parturition. onset of lactation is synchronized with the eclosion of the first instar larva. the changes in cell volume (notably in the extracellular reservoir) occurring throughout the pregnanc ...19751145609
inhibition of diuresis in the tsetse fly (glossina morsitans) by ouabain and acetazolamide.acetazolamide and ouabain, metabolic inhibitors which interfere with certain membrane transport systems, reduce the rate of water elimination by male glossina morsitans morsitans. the results suggest that water is transported across membranes during diuresis and that a ouabain sensitive na+k+atpase and an acetazolamide-sensitive carbonic anhydrase are involved in diuresis.19751157860

diuresis in the tsetse fly glossina austeni.after taking a blood meal, the tsetse fly glossina austeni excretes the excess water and salts of the meal in approximately 30 min. during this period a volume of fluid equivalent to 80% of the unfed weight of the fly passes through the haemolymph, whose composition nevertheless remains almost constant. the fluid excreted has a higher sodium and lower potassium concentration than the haemolymph, indicating that sodium may be the prime mover in urine formation in glossina.19751202130
the control of diuresis in the tsetse fly glossina austeni: a preliminary investigation of the diuretic hormone.the rate of secretion of the malpighian tubules of glossina austeni is controlled by a diuretic hormone. this hormone is present in the nervous tissue of the fly together with a degradative enzyme that can be activated by boiling. it is demonstrated that the malpighian tubules are able to destroy the diuretic hormone; they may therefore participate in the control of diuresis. the diuretic hormone appears to be a heat-stable, non-dialysable, alcohol-soluble molecule, containing amino acid, glucos ...19751202131

the role of game animals in the maintenance of endemic and enzootic trypanosomiases in the lambwe valley, south nyanza district, kenya.rhodesian sleeping sickness and bovine trypanosomiasis were endemic in the lambwe valley of western kenya, where the vector of both diseases was a tsetse fly glossina pallidipes. since a large resident population of game animals also inhabited the valley, a programme was designed to assess the relationships between game animals, tsetse, and trypanosome populations and the results were collated with some aspects of local human ecology and the general epidemiological situation in the valley. of 13 ...19724544824

glycerol kinase activities in muscles from vertebrates and invertebrates.1. glycerol kinase (ec 2.7.1.30) activity was measured in crude extracts of skeletal muscles by a radiochemical method. the properties of the enzyme from a number of different muscles are very similar to those of the enzyme from rat liver. glycerol kinase from locust flight muscle was inhibited competitively by l-3-glycerophosphate with a k(i) of 4.0x10(-4)m. 2. the activity of glycerol kinase was measured in a variety of muscles from vertebrates and invertebrates in an attempt to explain the la ...19695801671
control of the african trypanosomiases with special reference to land use.there is a need to reassess the role of the trypanosomiases, both human and animal, in african ecology and economy. withdrawal of control services from the congo basin was followed by a resurgence of infection from ancient foci, many of them thought to have been extinguished. successful elimination of glossina in savanna habitats has sometimes been followed by reinvasion causing massive epizootics. elsewhere continued recession of the tsetse fly has been followed by cattle population growth whic ...19695307600
aerial applications of insecticides for tsetse fly control in east africa.since 1948, research has progressed in east africa on the control of tsetse flies by aeria, applications of insecticides. initial experiments proved that residual spray treatments were ineffective while repeated applications of coarse aerosols gave promising fly mortalities.in recent years, with the development of more toxic insecticides used in conjunction with improved thermal exhaust equipment and modified rotary atomizers, sprays with fine aerosol characteristics have been produced at consid ...19695308701

recent advances in techniques for tsetse-fly control.with the advent of modern persistent insecticides, it has become possible to utilize some of the knowledge that has accumulated on the ecology and bionomics of glossina and to devise more effective techniques for the control and eventual extermination of these species.the present article, based on experience of the tsetse fly problem in northern nigeria, points out that the disadvantages of control techniques-heavy expenditure of money and manpower and undue damage to the biosystem-can now large ...19675301739

the distribution of the vectors of african pathogenic trypanosomes.the author lists the species, subspecies and races of tsetse fly now recognized in three morphologically distinct groups. the distribution of each group is mapped and described in relation to climate and vegetation, with some indication of the part played by past climates and orogenies in determining the modern pattern. the importance of different species as vectors of human or bovine trypanosomiasis, or both, is noted, and examples are given of the part played by human settlement as a secondary ...196313958704
tsetse-fly control and eradication.in many instances the cheapest and quickest way of controlling trypanosomiasis is to reduce the number of vectors and the opportunities for contact between man and vector. for permanent results, moreover, eradication of the vectors is necessary, since eradication of trypanosomiasis by chemotherapeutic means has so far not proved feasible.for a variety of reasons, game destruction as a method of fly control is gradually being replaced by other methods. of these, the complete removal of bush cover ...196313963757
human trypanosomiasis in south-east uganda. a further study of the epidemiology of the disease among fishermen and peasant cultivators.during the past two decades there has been an increase in the incidence and spread of sleeping-sickness due to trypanosoma rhodesiense throughout the north-eastern shore area of lake victoria; this increase has been associated with heightened finishing activity and increasing and irregular settlement of the tsetse-fly belt of south-east uganda.the author describes a number of epidemiological factors affecting the occurrence of the disease among fishermen, placing emphasis on the correct developm ...196313974352

the feeding habits of glossina.the feeding habits of 15 species of glossina have been studied by the identification of their blood meals. representative samples of the blood meals from each of these species of tsetse fly and from different habitats were collected and 22 640 blood meals were identified. the feeding patterns are characteristic for each species of tsetse fly and do not appear to depend entirely on the availability of different hosts, suggesting that the feeding habits of glossina are genetically determined. howe ...196313999790

the effects of trypanosomiasis on rural economy with special reference to the sudan, bechuanaland and west africa.trypanosomiasis, both of humans and of livestock, is one of the most important factors restricting economic development in africa today. the present paper outlines how this disease is limiting agricultural, veterinary and forestry development in the sudan, bechuanaland and west africa.the present tsetse-fly distribution is reviewed. glossina palpalis and g. morsitans occur in the south sudan and g. morsitans in the ngamiland district of bechuanaland; g. morsitans, g. palpalis and g. tachinoides ...196314001093
tsetse-fly physiology. a review of recent advances and current aims.a review of the literature on tsetse-fly physiology published during the last decade shows that substantial advances have been made in elucidation of the problem of water balance, and in the fields of reproductive and developmental physiology. it is suggested that further studies of reproduction, with particular reference to the reproductive potential of natural populations, are urgently needed; and also that research could fruitfully be directed towards an assessment of the role of starvation a ...196314017193
