A comparative study on development of the bean beetle Acanthoscelides obtectus (Say) in bean, cowpea, and pigeon pea seed diets
Khamala, CP (University of Nairobi,School of Biological Sciences, 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 ... -

The dynamics of Anopheles arabiensis Patton and Anopheles funestus Giles larval densities in relation to small-scale rice cultivation practices in Western Kenya
Khamala, CP (University of Nairobi,School of Biological Sciences, 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 ... -
Estimation of the survival rates of field populations of malaria vectors in Kenya
Khamala, CP (University of Nairobi,School of Biological Sciences, 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 ... -
Evaluation of resistance to insecticides in the mosquito larvae of Anopheles gambae Giles and its control by microbial bacterial pathogens
Khamala, CP (University of Nairobi,School of Biological Sciences, 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 ... -
