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
storage and sexual separation of glossina morsitans morsitans westwood puparia.maintenance of unknown-age tsetse puparia at 4 degrees c for six days substantially reduced emergence; normal emergence occurred when puparia were held at temperatures of 12 degrees, 14 degrees, or 16 degrees c for two, three or four weeks, respectively. in-storage eclosion of adults was either suppressed completely at the temperatures used or was slight. weight, puparial duration, and density of puparia were examined in an attempt to detect sexual differences in puparia. there appeared to be no ...19751155998

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

quantitative ultrastructural investigations of the life cycle of trypanosoma brucei: a morphometric analysis.the quantitative ultrastructure of the developmental stages of trypanosoma brucei brucei in its vector glossina morsitans was studied by morphometric analysis. values from ectoperitrophic midgut forms, proventricular forms, epimastigote and metacyclic forms in the salivary gland are compared with results from bloodstream forms, published previously. significant differences in the volume densities of the trypanosome's single mitochondrion, of microbody-like organelles and in the surface densities ...19751195156
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

productivity of glossina morsitans morsitans westwood maintained in the laboratory, with particular reference to the sterile-insect release method.glossina morsitans is of great economic importance in africa and if a mass-rearing project were to be undertaken with a view to control by the release of sterilized males it would be necessary to know the productivity that could be obtained from this species in the laboratory. data for life tables and age-specific fecundity schedules of g. m. morsitans fed on goats or lop-eared rabbits are used to calculate outputs of viable pupae or of young adult males that would be available for disposal.for ...19724537332
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

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
