his study was undertaken to provide new knowledge on biodiversity of aphids and their complex of natural enemies in vegetable agroecosystems in Benin. During a 2-year survey (2007/2008 to 2008/2009), aphid species, their host plants and natural enemies were identified from samples collected from ...

Weed abundance in cereal-based systems has increased in recent years across sub-Saharan Africa for smallholder farmers (cultivating less than two hectares). Smallholders can employ numerous practices to control weeds such as intercropping cereal crops with legumes. We conducted a review to identi...

Seeds of Striga asiatica and S. hermonthica were separated from soil using a wet sieve method with a 2.5 smallcap˜M sucrose flotation solution and 250- and 150-µm mesh screens. In 34 fields, the av. and range of seeds/100 g of soil were 8.2 and 0-75, resp. Seeds were recovered from 28 of the 34 f...

The effect of alley cropping with seven combinations of Acioa and Leucaena hedgerows and a control (no hedgerow) treatment on sequentially cropped maize and cowpea was studied in 1985 and 1986. The trial was carried out on an Alfisol in the humid zone of southwestern Nigeria. Hedgerows were estab...

The Projet Recherche Appliquée en Milieu Réel is situated on the Adja Plateau, Southwest Benin. The project is responsible for a FSR&D programme that aims at sustainable use of the so-calledTerres de barre. Technologies tested in this context include seasonal fallowing, usingMucuna pruriens cv. g...

In the humid forest regions of southern Cameroon in central Africa, sectoral and macroeconomic policy reforms introduced in the late 1980s have led to intensified land use, which in turn has resulted in, among other environmental consequences, shortened fallow systems dominated by the Asteraceae ...
