Studies on Population densities and some aspects of Control of the common Maize Stalkborer Chilo partellus Swinhoe, C. Orichalcocililla Strand. and Sesamia calamistis Hmps
(University of Nairobi,, 1981)
The population densities of the three coastal maize stalkborers, Chilo partellus Swin. C. orichalcoiliella Strand. and Sesamia calamistis Hmps. were estimated during the long rains of 1979, 1980 and 1981, showed the ...
Estimation of the survival rates of field populations of malaria vectors in Kenya
(University of Nairobi,, 1985)
Results revealed that the average survival rates between the dry and the wet seasons mosquito populations of individual species was possible in An gambiae s. str. The survival for this species was higher during the dry ...
Mechanisms of Sorghum resistance to the spotted stalkborer, Chilo partellus (Swinhoe) (Lepidoptera: Pyralidae)
(University of Nairobi,, 1985)
The spotted stalkborer Chilo partellus is one of the most notorious pests in Kenya of cereal crops especially maize and sorghum particularly in semi-arid areas. These studies showed that ovipositing maize stalkborers have ...
The dynamics of Anopheles arabiensis Patton and Anopheles funestus Giles larval densities in relation to small-scale rice cultivation practices in Western Kenya
(University of Nairobi,, 1990)
A two-year study was conducted on the densities of Anopheles arabiensis Patton and Anopheles funestus Giles larvae in two rice cultivation sites with divergent farming practices, at the Ahero Irrigation Scheme, Kenya. The ...
Evaluation of resistance to insecticides in the mosquito larvae of Anopheles gambae Giles and its control by microbial bacterial pathogens
(University of Nairobi,, 1989)
It was found that resistance factors of mosquito larvae were near unity for dieldrin, and 2 to 3 times for Malathion at both Ahero and Mwea, and 2 times for DDT at Ahero. These low resistance factors indicated little or ...
Pest Management of Grain Legume Crops in Multiple Cropping Systems
(University of Nairobi,, 1979)
Larval habitats of the common biting midges Culicoides Latreille (Diptera: Ceratopogonidae) in Kenya
(University of Nairobi,, 1972)
The larval habitats of Culicoides species were determined by examining a total of 1476 samples collected from different ecological environments in various parts in Kenya. Immature stages were collected from suspected ...
A comparative study on development of the bean beetle Acanthoscelides obtectus (Say) in bean, cowpea, and pigeon pea seed diets
(University of Nairobi,, 1980)
Results indicated that the differences in the numbers of beetles developing in beans, pigeon peas, and cowpeas were statistically significant at the third generation level. The average life cycle in a generation was shorter ...
