(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 ...
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 ...
Virtues of composite structures in electrode modification. Preparation and properties of poly (aniline)/nafion composite films
Poly(aniline) (PA) is electropolymerized within thin films of precast Nafion on gold or glassy carbon electrodes. The quartz crystal microbalance (QCM) is used to aid in identification of the ionic species that undergo ...
