Performance of a prototype baited-trap in attracting and infecting the tick Amblyomma variegatum (Acari: Ixodidae) in field experiments
(University of Nairobi., 2006)
Investigations were commenced to study the potential use of the fungi, Beauveria bassiana, Metarhizium anisopliae, and the attraction-aggregation-attachment pheromone (AAAP) for the control of Ambloyomma variegatum as an ...
The impact of Ixodiphagus hookeri, a tick parasitoid, on Ambl yomma variegatum (Acari: Ixodidae) in a field trial in Kenya
(Uniiversity of Nairobi., 1997-02-01)
In an experiment to investigate the effect of the tick parasitoid, Ixodiphagus hookeri, on tick numbers on cattle, 150 000 parasitoids were released over a period of 1 year in a field where ten cattle infested with multiple ...
Characteristics of erythroid colonies formed by bovine marrow progenitor cells in methyl cellulose cultures
(University of Nairobi., 1982-03)
Bovine erythroid colonies containing eight to 100 erythroid cells were successfully cultured in methyl cellulose. The colonies required four to five days to mature and a direct linear relationship (r = 0.99) between the ...
Inhibition of bovine bone marrow granulocyte/macrophage colony formation in vitro by serum collected from cattle infected with Trypanosoma vivax or Trypanosoma congolense
(University of Nairobi., 1979-06)
Serum collected from cattle infected with Trypanosoma vivax or Trypanosoma congolense inhibited bovine granulocyte/macrophage colony formation in methyl cellulose cultures. Maximum inhibition was caused by serum collected ...
Determination of optimum seaweed concentration for mushroom cultivation and the ability of mushrooms to absorb iodine
(©2012 Academic Journals, 2012-07)
The optimum concentration of seaweed (Laminaria schinzii) in grass as substrate for cultivation of the Oyster mushroom Pleurotus sajor caju was observed to be 10%. This concentration supported growth of highest numbers and ...
Ticks and tick-borne parasites associated with indigenous cattle in Didtuyura Ranch, southern Ethiopia
(University of Nairobi., 1998)
Tick populations were monitored between October 1991 and September 1992 at monthly intervals on 10 Boran (Bos indicus) heifers at Didtuyura ranch, Yabelo district, Ethiopia. Twelve different tick species in four genera ...
Prospects for Innovative Tick Control Methods in Africa
(University of Nairobi., 2003-03)
Ticks, and the diseases they transmit, are of great economic and medical importance worldwide, and especially in Africa, where they are considered to be the greatest animal disease problem. The four major genera of ticks ...
Drop-off patterns for engorged adult females, nymphs and larvae of Rhipicephalus appendiculatus
(University of Nairobi., 1991-12)
A drop off rhythm of engorged Rhipicephalus appendiculatus Neumann was demonstrated for females and engorged nymphs, but not for larvae. Seventy per cent of 1279 engorged R. appendiculatus females dropped off the animals ...
Cuticular lesions: a non-infectious integumental disease of Glossina species
(University of Nairobi., 1981-12)
Purified suspensions of macerated cuticular lesions from the insectary-reared tsetse Glossina morsitans morsitans were applied on laboratory-reared newly emerged teneral tsetse by three pathways: topical application on the ...
Experimental infections of the tick Rhipicephalus appendiculatus with entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae, and natural infections of some ticks with bacteria and fungi
(University of Nairobi., 1995-09)
Two strains of the entomogenous fungus, Beauveria bassiana, were found to be pathogenic to all stages of the tick Rhipicephalus appendiculatus in the laboratory. A mortality of up to 73 percent of unfed adults was recorded, ...
