Diversity of alternative hosts of maize stemborers in Trans-Nzoia district of Kenya.
Genetically-engineered (GE) crops such as those expressing insecticidal Bacillus thuringiensis (Bt) toxin genes have the potential to greatly reduce the use of broad spectrum insecticides and increase crop productivity. However, development of resistance by the target insect species is an important consideration in the deployment of this strategy. In areas where GE crops are deployed on a large...
متن کاملAflatoxin levels in locally grown maize from Makueni District, Kenya.
OBJECTIVES Investigations were carried out to determine aflatoxin levels in household maize in Makueni District and to correlate aflatoxin levels to maize drying and storage practices. Also, aflatoxin exposure in villages that reported aflatoxicosis cases in 2005 was compared with that in villages that did not report cases to assess whether aflatoxin exposure levels could be used to identify hi...
متن کاملSeparation of maize particles from alcohol extracts with minimal losses
Low-cost extraction of maize protein using ethanol at the front end of a dry grind ethanol plant has been discussed in recent articles. Thorough recovery of (alcoholic) extract from the extracted maize is essential to make the process economical and to prevent the ethanol from interfering with liquefaction enzymes or fermentation organisms where the solid residues are to be subsequently reduced...
متن کاملHousehold dietary exposure to aflatoxins from maize and maize products in Kenya.
Aflatoxicosis has repeatedly affected Kenyans, particularly in the eastern region, due to consumption of contaminated maize. However, save for the cases of acute toxicity, the levels of sub-lethal exposure have not been adequately assessed. It is believed that this type of exposure does exist even during the seasons when acute toxicity does not occur. This study, therefore, was designed to asse...
متن کاملA Market for Lemons: Maize in Kenya*
Information asymmetries are a well-recognized impediment to market efficiency. When quality is not observable by prospective buyers, the quality of marketed goods will suffer, and the volume of trade will be depressed. Using data from more than 2,000 maize samples collected in four Kenyan provinces, we show that the presence of aflatoxin, an invisible and dangerous fungal contaminant, is not re...
