A review of the existing basis for maize stem borer IPM is given and the role of pathogens in the system is evaluated. Survey work outlining the major groups of insect pathogens is described; fungi (Beauveria bassiana and Metarhizium anisopliae), bacteria (Bacillus thuringiensis and Serratia marc...

Pathogen incidence and their potential as microbial control agents in IPM of maize stem borers in West Africa
Difficulties of identification of natural enemies of cereal stemborers for 'redistribution' in Africa are discussed. Tritrophic level studies on wild and cultivated habitats of borers and beneficial species are needed to judge the impact of a natural enemy species in the cropping system. Areas wi...

Exchanging natural enemies species of lepidopterous cereal stemborers between African regions
Three surveys of maize fields were undertaken in 1993 in Cameroon, ranging from low to high altitudes, and from forests in the south with bimodal rainfall (two cropping seasons) to the northern savanna with monomodal rainfall distribution (one cropping season). Field conditions, insects and disea...

A systems approach to assess crop health and maize yield lossess due to pests and diseases in Cameroon
The pink stem borer (Sesamia calamistis Walker (Pyralidae)) and the sugarcane borer (Eldana saccharina Hampson (Noctuidae)) are among the most damaging pests of maize in West and Central Africa, a region where IITA invests considerable effort in improving productivity of maize-based systems. The ...
