The major mycotoxins studied at the Consultative Group on International Agricultural Re-search (CGIAR) institutes are aflatoxins in maize, groundnut, sorghum and cassava, Fusa-rium toxins in maize, wheat and sorghum, and ochratoxin in cocoa and cashew. Genetic en-hancement (both through plant bre...

In trials conducted in Benin, conidia of Beauveria bassiana were evaluated as a control method against the cowpea weevil, Callosobruchus maculatus, in stored cowpea. In the first trial using a high artificial infestation of C. maculatus in 8-kg batches of cowpea in jerry cans under typical condit...

Maize infection by Aspergillus flavus Link and subsequent aflatoxin contamination as affected by insect damage to maize ears before harvest was studied with surveys in farmers' fields and in a field trial in the Republic of Benin, West Africa. The most important pest species was the lepidopteran ...

Effect of insect damage to maize ears, with special reference to Mussidia nigrivenella (Lepidoptera; Pyralidae), on Aspergillus flavus (Deuteromycetes; Monoliales) infection and alfatoxin production in maize before harvest in the Republic of Benin
In West Africa, the most damaging lepidopteran pest of maize ears is the pyralid Mussidia nigrivenella. Although it is mostly described as a field pest, it can be found feeding on maize stored for up to 4 months. A survey was conducted in Benin in 2006 to assess M. nigrivenella infestations in di...

Pre- and postharvest contamination of aflatoxin in maize is a major health deterrent for people in Africa where maize production has increased dramatically. This chapter highlights management options for pre- and postharvest toxin contamination in maize. Sound crop management practices are an eff...

Morphological characteristics and agronomic parameters were studied on 16 sweet-potato varieties (5 East Africa, 9 Benin, 1 China and 1 Bolivia) in April to August 2011 in southern Benin. Varietal variability was observed for length of internodes, leaf petiole, stem and leaf number. Positive sign...

Fusarium is one of the major fungal genera associated with maize in Africa. This genus comprises several toxigenic species including F. verticillioides and F. proliferatum, which are the most prolific producers of fumonisins. The fumonisins are a group of economically important mycotoxins and ver...
