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
(1982)
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 ...
Factors influencing vector/parasite transmission of Theileriosis in Africa
(University of Nairobi., 1998)
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. ...
Acquisition of resistance to the tick Amblyomma variegatum in Boran cattle, Bos indicus and the effects of Trypanosoma congolense and Babesia bigemina on host resistance
(University of Nairobi., 1996-04)
Resistance was induced in cattle to the tick Amblyomma variegatum by five consecutive infestations with nymphs and adults. Using the principal component analysis (PCA), it was found that percentage of adults engorged, ...

Changes in the ovaries, pituitary, thyroid and adrenal glands in Small East African normally cycling female goats chronically infected with T. congolense are described. Marked fibrosis of the ovaries, a decrease in the ...
The effects of Trypanosoma congolense infection on the testis and epididymis of the goat
(Uniiversity of Nairobi., 1980-03)
Five male non-castrated goats were each injected with 2 ml of blood from an infected goat containing about 0.75 million T. congolense/ml. Two goats died 4 weeks after infection; the remainder and five controls were killed ...
Laboratory and Field Evaluation of Entomogenous Fungi for Tick Control
(University of Nairobi., 2000-12)
Aqueous and oil-based formulations of two entomogenous fungi, Beauveria bassiana and Metarhizium anisopliæ were tested for their efficacy against the three major species of African ticks; namely, Amblyomma variegatum, ...
