Popis:	A farmer survey was conducted in six agro-ecological zones (AEZs) in semi-arid eastern Kenya to verify the socio-economic importance of maize, identify its pests and farmers' perceptions of the relative importance of the pests. We also determined some agronomic practices that may influence stemborer infestation and identified the stemborer control methods used. Pests reported included chafer grubs, stemborers, termites, 'red ants', yellow-necked spur fowls, squirrels, monkeys, porcupines, rats, wild pigs and storage insect pests. Their relative importance in each AEZ is discussed. The squirrel was the most widely distributed and important vertebrate pest of maize in the study AEZs. Stemborers infested maize in all the zones, and ranked first among insect pests in the Upper Midland zone 4 (UM4), Lower Midland zone 3 (LM3) and LM4, and second in LM5, but were unimportant in UM2. Agronomic practices that may influence stemborer infestation in maize, including cropping system, sowing time, fertilizer/manure u...
