Non-chemical agents and factors capable of regulating tick populations in nature: A mini review
(University of Nairobi., 1992-08)
Ticks have always been a major obstacle to livestock production due to the devastating diseases which they transmit especially in the tropics. The control of ticks which has relied heavily on the use of acaricides is now ...
Comparison of resistance in three breeds of cattle against African ixodid ticks.
(University of Nairobi., 1996-04)
Tick resistance in three breeds of cattle, two indigenous breeds (Arssi and Boran) and one Boran x Friesian cross-bread, were compared following natural tick infestations at Abernossa ranch in Ethiopia. The local Arssi ...
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 ...
Predation of free-living engorged female Rhipicephalus appendiculatus
(University of Nairobi., 1991-10)
In experiments done over a period of 1 1/2 years using engorged female Rhipicephalus appendiculatus tethered in a grass plot, 42% predation was observed in long grass (40-60 cm), and 36% in short grass (6-10 cm). Deaths ...
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 ...
