The humoral defense system in tsetse: differences in response due to age, sex and antigen types.
(University of Nairobi., 1988)
Inoculation of live Escherichia coli into tsetse flies, Glossina morsitans morsitans, stimulated a higher antibacterial immune response in females than in males. It increased with age in females from emergence to approximately ...

(University of Nairobi., 1989-05)
Differences in susceptibility of the Small East African breed of goats to an experimental Trypanosoma congolense infection were investigated. The goats were obtained from different areas of East Africa, Morogoro and Arusha ...
Effects of combining the fungi Beauveria bassiana and Metarhiziumanisopliae on the mortality of the tick Amblyomma variegatum (ixodidae) in relation to seasonal changes
(University of Nairobi., 2005-06)
The effect of formulation, fungal concentration, type and seasonal changes on the mortality of the tick Amblyomma variegatum was investigated. A previous study demonstrated high pathogenicity of strains of the fungi Beauveria ...
Control of tick populations by spraying Metarhizium anisopliae conidia on cattle under field conditions
(University of Nairobi., 2011-11)
Conidia of the entomopathogenic fungus, Metarhizium anisopliae, in oil/water formulation (1 × 10(8) conidia/ml) were sprayed at 3 weekly intervals on Rhipicephalus evertsi evertsi and Rhipicephalus (Boophilus) decoloratus ...
Fecundity and survival of tsetse maintained on immunized rabbits Kaaya Godwin P.; Alemu Patrick
Female Glossina morsitans morsitans maintained on rabbits previously immunized with whole tsetse body (WTB), engorged tsetse guts (ETG) or gravid tsetse uteri (GTU) for three successive generations showed no increase in ...

The potential for antitick plants as components of an integrated tick control strategy
(University of Nairobi., 2000)
Extracts from various African plants have been shown to possess strong acaricidal and/or tick repellent properties. Some of the plant extracts are capable of reducing tick feeding, molting, fecundity, and viability of eggs. ...
