Abstract: Pratylenchus goodeyi is a recognized pest of bananas and plantains in African highland regions. To evaluate the crop host status of P. goodeyi in the Cameroon Highlands, a field experiment was conducted in a field previously cropped with banana, using 12 crops planted in a randomized design with four replicates. The site was at Mbouroukou near Melong at 1200 m above sea level on volcanic soils. Banana was the susceptible reference crop. Sampling of roots and rhizosphere soil was undertaken at 4 months after planting. A non-parametric ANOVA revealed significant differences in P. goodeyi root population densities among the treatments (crops). Crops were classified as good hosts of P. goodeyi when their mean root densities were statistically similar to banana. When mean P. goodeyi root densities were significantly lower than banana but higher than 1000 100 g(-1) FRW, crops were classified as intermediate hosts. Crops with a mean P. goodeyi root density significantly lower than banana and lower than 1000 nematodes 100 g(-1) FRW were classified either as poor hosts (> 20 P. goodeyi 100 g(-1) FRW) or very poor hosts (<= 20 P. goodeyi 100 g(-1) FRW). Beans and maize (cv. CMS 8704) were good hosts of P. goodeyi; watermelon and onion were intermediate hosts; maize (cv. Kasai), taro, okra, Irish potato and sweet potato were poor hosts, while cocoyam and tomato were very poor hosts.
