Abstract
Abstract A survey was conducted during 1999 and 2001 in Ashanti, Brong Ahafo, Eastern, and Volta regions of Ghana, West Africa, to identify nematode pests of peanut (Arachis hypogaea L.). Information from the survey is being used to formulate appropriate integrated pest management (IPM) strategies for peanut production in these regions. Ten genera of plant parasitic nematodes belonging to three Orders were identified. Population density and distribution of genera varied in the four peanut-growing regions. Six genera, Helicotylenchus, Meloidogyne (juveniles), Paratrichodorus, Pratylenchus, Rotylenchulus, and Xiphinema were found in all four regions. Hoplolaimus was found only in the Eastern region. Trichodorus and Tylenchorhynchus were absent from Ashanti and Brong Ahafo regions but present in Eastern and Volta regions. Nematode genus Rhignema of the Order Rhigonematida was isolated from millipedes sampled from the rhizosphere of peanut. Twenty-one peanut cultivars and experimental lines were assembled fro...
