Nature, 1960
CORRELATED with the viviparous type of reproduction found in the tsetse fies, the essential features of which were worked out as early as 1895 by Bruce1, there is a great reduction in the number of ovarioles. Stuhlman2 and Roubaud3 studied the anatomy of the female reproductive organs and considered that each ovary consisted of a single ovariole, a ...

Effect of Two Chemosterilants on Glossina morsitans
Nature, 1964THE use of sterile males offers a theoretical advantage over the use of insecticides in insect control1. This advantage is greater in the control of low-density pest species such as the screw-worm2. The sterile male technique has therefore been suggested for the control of tsetse flies, and Potts3 examined the effects of γ-radiation on tsetse fly pupae.

The meiotic sequence in Glossina morsitans morsitans
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1972Abstract The diploid chromosome number in those male G. m. morsitans examined is 2n = 8 ± 1 autosomes and the XY sex pair. Meiosis is almost certainly achiasmate and there is no recognizable diplotene or diakinesis. Only the 4 largest autosomes form bivalents (L1 and L2), the remaining small chromosomes appearing as univalents.

Lipophorin from the tsetse fly, Glossina morsitans morsitans
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19911. Lipophorin was isolated from the haemolymph of adult tsetse fly, Glossina morsitans morsitans, by ultracentrifugation in a potassium bromide density gradient. 2. The tsetse fly lipophorin (Mr congruent to 600,000) has a density of congruent to 1.11 g/ml and consists of two apoproteins, apolipophorin-I (apoLp-I, Mr congruent to 250,000) and ...

Polytene chromosomes of the tsetse fly Glossina morsitans morsitans
Chromosoma, 1973Cytological maps have been prepared, and a detailed description is presented of all major markers in the polytene chromosomes of the tsetse fly Glossina morsitans morsitans, an important vector of African trypanosomiases. Only the five eu-chromosomes in males (L1 and L2 autosome pairs plus X chromosome) and the six eu-chromosomes in females of the ...

Chromosoma, 1974
Polytene chromosome maps of the tsetse fly Glossina austeni have been prepared and a description of all the principal chromosome markers is provided. A detailed comparison has been effected between these chromosomes and the polytene elements of G. m. morsitans the only other member of the same sub-genus so far mapped.

Proventriculus-specific cDNAs characterized from the tsetse, Glossina morsitans morsitans
Insect Biochemistry and Molecular Biology, 2002Peritrophic matrix (peritrophic membrane or PM) is an important structure in the gut of most insects at some stage in their development. It is composed of chitin, proteins and proteoglycans. Multiple roles for the PM ranging from partitioning of digestive enzymes and food to protection of gut epithelial cells from viral and parasitic invasion have been

Spectral responses of the tsetse fly, Glossina morsitans morsitans
Journal of Insect Physiology, 1983Abstract Spectral responses of male Glossina morsitans morsitans Westw, were investigated using behavioural and electrophysiological techniques. Phototactic responses to monochromatic lights of different wavelengths but equivalent intensities (measured either in energy or quantal units) were tested in an apparatus which permitted the simultaneous ...

Storage and sexual separation ofGlossina morsitans morsitansWestwood puparia
Annals of Tropical Medicine & Parasitology, 1975Maintenance 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.
