After insects, mites are the major arthropod pests that inhabit stored agriculturalproducts worldwide. To determine the acarofauna that infests cowpea, maize, paddyrice and sorghum in Benin (West Africa), surveys were conducted in some principalmarkets (Dantokpa, Glazoue and Parakou) of this coun...

Dried yam (Dioscorea spp.) chips are widely consumed in Bénin but are often attacked by molds. Invasion of food by Aspergillus flavus may lead to aflatoxin contamination. We report here the result of a survey on the sanitary quality of dried yam chips in Bénin. During July and August 2000, 50 dri...

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...

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...

BACKGROUND: Maize constitutes the main staple food and most important crop grown in Zambia. However, maize incursconsiderable losses both in field and storage due to pathogens and insects. Some of the pathogens and resultant mycotoxinsreduce the nutritional quality of the product. Mycotoxins are ...
