Preliminary observations on the population development of anystid and free-living mesostigmatic mites in a cereal field in Southern England
(University of NairobiSchool of Biological and Physical Sciences, 1993-07)The effect of manipulating cereal aphid population development, by either adding aphids or spraying with an aphid-specific insecticide, on the predatory mite fauna was investigated. Populations of the anystid mite, Anystis ... -
Preliminary reports on Radon Concentration in Drinking Water and Indoor Air in Kenya
(Department of Physics, University of Nairobi., 2002)A screening survey has been carried out to determine activity concentrations of radon (222Rn) in drinking water and indoor air in various locations in Kenya. The concentration of 222Rn in water was measured using a liquid ... -
