Lack of evidence for sufficiently isolated populations of Glossina morsitans submorsitans on the Adamawa Plateau of Cameroon following geometric morphometric analysis

open access: yesAdvances in Entomology (Irvine, Calif ), 2013
Trypanosomosis remains the number one killer of livestock in spite of efforts made to eradicate tsetse flies in the Adamawa plateau of Cameroon. Acetone-baited Laveissiere type biconical traps were pitched at 100 meter intervals in strategic geo-referenced positions in various ecological niches of the landscape for 5 consecutive days in selected ...

Polytene chromosome maps in four species of tsetse flies Glossina austeni, G. pallidipes, G. morsitans morsitans and G. m. submorsitans (Diptera: Glossinidae): a comparative analysis

Genetica, 2006
Photographic polytene chromosome maps from pupal trichogen cells of four tsetse species, Glossina austeni, G. pallidipes, G. morsitans morsitans and G. m. submorsitans were constructed and compared. The homology of chromosomal elements between the species was achieved by comparing banding patterns. The telomeric and subtelomeric chromosome regions were

The decline of a Glossina morsitans submorsitans belt in the Egbe area of the derived savanna zone, Kwara State, Nigeria

Medical and Veterinary Entomology, 1991
Abstract. In the the early 1970s the Egbe area of Nigeria was known to be one of high trypanosomiasis risk, with four Glossina species G.morsitans submorsitans Newstead, G.longipalpis Wiedemann,

The feeding habits and ecology of the tsetse fly "Glossina morsitans submorsitans" Newstead in relation to nagana transmission in The Gambia

Acta tropica, 1979
The source of blood meals from 174 fed Glossina morsitans submorsitans Newstead, captured in malaise traps in Savanna woodland in The Gambia, were identified by the precipitin test. Warthog accounted for 90% of the meals and single bushbuck and ox feeds were identified.

MAPPING FOUR LOCI IN GLOSSINA MORSITANS SUBMORSITANS NEWSTEAD (DIPTERA: GLOSSINIDAE)

The Canadian Entomologist, 1989
Glossina morsitans submorsitans Newstead has two pairs of autosomes, a pair of sex chromosomes (males are heterogametic), and from two to seven supernumerary (=B) chromosomes (Southern and Pel1 1973). The only information allowing assignment of loci to linkage groups in this subspecies is that electrophoretic evidence suggests that five polymorphic ...

Sex ratio distortion inGlossina morsitans submorsitansNewstead (Diptera: Glossinidae)

Bulletin of Entomological Research, 1984
AbstractA laboratory colony ofGlossina morsitans submorsitansNewst. originating from Nigeria exhibits an excess of females over males. The sex ratio distortion of more than two females to one male was studied by the maintenance of individual flies. Five males sired more than ten daughters without producing any sons when mated to several females, whilst

Genetic basis of sterility in hybrids from crosses of Glossina morsitans submorsitans and Glossina morsitans morsitans (Diptera: Glossinidae)

Genome, 1989
Glossina morsitans submorsitans Newstead and Glossina morsitans morsitans Westwood carrying two marker genes on the X chromosome, two in linkage group II, and one in linkage group III were hybridized. About 17% of the F1 and from 33 to 56% of the backcross males fertilized G. m. submorsitans, but only one F1 and two backcross males fertilized G.

Observations on the ecology of Glossina morsitans submorsitans Newst. in the Northern Guinea Savannah of Northern Nigeria

Bulletin of Entomological Research, 1965
Observations, largely based on regular catches along a fly-round, were made over the five years 1959–64 on a population of Glossina morsitans submorsitans Newst. in the Northern Guinea Savannah of Nigeria. The results showed that the largest numbers of flies were caught in the early dry season (November–January) and that, as the climate became ...

Epizootiological importance of Glossina morsitans submorsitans (Diptera: Glossinidae) (Newstead) in the Ghibe River Valley, Southwest Ethiopia

Acta Tropica, 2007
The epizootiological importance of Glossina morsitans submorsitans in Ghibe River Valley was undertaken from October 2000 to September 2001. The flies were collected using baited monoconical traps. G. m. submorsitans occurred with a mean apparent density of 4.26+/-0.49 flies/trap/day and the apparent density was characterized by an increase during the ...

Genetic analysis of sterility in hybrids from crosses of Glossina morsitans submorsitans and Glossina morsitans centralis (Diptera: Glossinidae)

Canadian Journal of Zoology, 1993
When genetically marked Glossina morsitans submorsitans Newstead were mated to Glossina morsitans centralis Machado, viable offspring were obtained when using G. m. submorsitans females but not when using G. m. centralis females. The maternally inherited sterility factor, from G. m.
