Evaluation of traits of resistance to postharvest insect pests in tropical maize
The maize weevil Sitophilus zeamais (Motschulsky) is among the most grain damaging insect in sub-saharan Africa. The objective of the study was to determine differences in traits associated with resistance to the maize ...
Responses of tropical maize landraces to damage by Chilo partellus stem borer
The potential to manage insect pests using host-plant resistance exists, but has not been exploited adequately. The objective of this study was to determine the resistance of 75 tropical maize landraces through artificial ...
Quantification of Bt Delta-endotoxins in leaf tissues of tropical Bt maize populations
In Kenya, stem borers destroy an estimated 13.5% of farmers' annual maize harvest. Maize transformed using Bacillus thuringiensis (Bt) derived genes controls stem borers without negative effects to humans, livestock or the ...
Quality of field collected and laboratory reared Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) for screening maize genotypes
The quality of laboratory reared stem borer species for screening of maize varieties is usually questioned by end user cereal breeders. A quality check study was performed in a screen house at KARI-Katumani to evaluate the ...
Development and deployment of insect resistant maize
(KARI; CIMMYT, 2000)
Participatory farmer evaluation of stem borer tolerant maize varieties in three maize growing ecologies of Kenya
Insect resistant maize for Africa (IRMA) project aims at developing and deploying insect resistant maize varieties to reduce grain losses due to insect pests. As part of incorporating farmers? perceptions to improve the ...
