The effect of pollen feeding on the predatory efficiency of Amblyseius gossipi (Acarina: Phytoseiidae)
(1968)A positive correlation between rate of prey consumption by A. gossipi and the prey density T. cinnabarinus was found at presence or absence of pollen of Zea mays. Pollen had no effect on prey consumption at prey concentrations ... -
The biomass of game animals in Nairobi National Park, 1960–66
(University of Nairobi, 1968)The large animals of Nairobi National Park have been censused intermittently once a month from mid-1960 until the end of 1966. Of the 23 species discussed, the density per kilometre has been determined accurately for the ... -
Effect of different prey species on the development and fecundity of the predacious mite, Amblyseius gossipi (Acarina: Phytoseiidae)
(1968)Under laboratory conditions of approximately 26.5–28.5° and 60–70% RH, the immature stages of the female Amblyseius gossipi Elbadry were completed in 2.9, 3.5 and 4.1 days when developed on Oligonychus mangiferus (R. & ... -
Chemosterilants With the Mosquitoes Culex Pipiens Fatigans(wiedemann and Anopheles Gamlae (Giles)
(University of Nairobischool of biological sciences, 1968)The possibility of control or eradication of an insect species by the release of overwhelming number of sterile males has been proven by experiment. On social ground it is considered that chemosterilants (chemicals capable ... -
Effectiveness of the predacious mite, Amblyseius gossipi as a predator of three tetranychid miets (Acarina: Phytoseiidae)
(1968)Test mites of Amblyseius gossipi Elbadry were confined to broad bean leaves in the laboratory at 26.5–28.5 C°. Adults A. gossipi fed readily on both adults and immatures of the spider mites Oligonychus mangiferus (R. & P.) ... -
Observations on the changing vegetation of Tsavo National Park (East)
(University of Nairobi, 1968-08)An analysis of woody vegetation in Tsavo National Park (East) by extensive variable-plot sampling indicates that the vegetation had been differentially destroyed up to 1966, but that by 1967 considerable local shrub ... -

Gonadal Development And Reproductive Activity Of The Cichlid Fish Tilapia Leucosticta (trewavas) In An Equatorial Lake
(University of Nairobi, 1969)THE most important external factors that influence gonadal development and reproductive activity are day length and temperature1. In temperate zones both factors show dramatic changes in the annual cycle. In the tropics, ... -

Mount elgon bat virus: A hitherto undescribed virus from Rhinolophus hildebrandtii eloquens K. Anderson
(Department of Zoology, College of Biological and Physical Sciences, University of Nairobi, 1969)A hitherto undescribed virus was isolated from salivary glands of a fruitbat of the speciesRhinolophus hildebrandtii eloquens (K. Andersen). Some of its properties are discussed. Of the viruses, isolated from organs of ... -
