A survey of plant parasitic nematodes in the major banana growing areas of Uganda was conducted in 1993. A total of 120 root samples were collected from 24 sites. Eight nematode species belonging to four genera were encountered. The most widespread species were Pratylenchus goodeyi (cob) sher and...

Developemental threshold and thermal requirements for eggs of banana weevil, Cosmopolites sordidus Germar, were determined under laboratory conditions at constant temperatures of 15,18,25,27,30,32 and 34 °C and a photoperiod of 12:12 L/D. The duration of the egg stage decreased from 34.9 days at ...

Twenty five sites, representative of seven agro-ecological zones of enset (Ensete ventricosum) crops, were sampled between September 1998 and January 1999. At each site, five 1-2 year old enset plants were sampled to check for the presence of nematodes present in their roots. The predominant nema...

East African highland cooking bananas (Musa spp., AAA) are one of the most important staples in the Great Lakes region of Africa. It has been hypothesized that land use intensification within the region has led to decline in soil fertility, increased pest pressure, and decline in production. To d...

The burrowing nematode Radopholus similis is one of the major constraints to banana (Musa spp.) production worldwide. Resource-poor farmers can potentially manage R. similis by using naturally occurring banana endophytes, such as nonpathogenic Fusarium oxysporum, that are inoculated into tissue c...

Highland cooking bananas (Musa spp. AAA) are a major staple in Eastern Africa. However, plant parasitic nematodes comprise a primary production constraint. Planting of infested material is the principle means of dispersal for these nematodes, as well as banana weevil and fusarium wilt. Nematode i...
