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 ...

The effect of covering post-harvest banana stumps with soil on banana weevil Cosmopolites sordidus (Germar) oviposition levels was investigated at three locations, Sendusu, Kawanda Agricultural Research Institute (KARI) and Ntungamo district of southwestern Uganda. In the first experiment oviposi...

Banana (Musa spp.) is a vegatatively propagated crop and the type of planting material is of great importancefor the productivity of banana plantations. Traditionally, sucker derived planting materials havebeen used to establish banana plantations but there is a risk of transmitting pests such as...

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...

Among the major constriats to highland cooking banana (Musa spp. AAA-EA) production in Uganda is the high pests infestation levels. Most important are the banana weevil cosmopolites sordidus and a complex of plant parasitic root nematodes of which Radopholus similis is the most important. Clean p...

The effects of a leaf spot complex (including Mycosphaerella musicola, M. fijiensis and Cladosporium musae) and leaf pruning on plant growth and yield in highland bananas were investigated in a field trial at Kawanda Agricultural Research Institute. Results from the first ratoon crop revealed tha...

Non-pathogenic endophytic Fusarium oxysporum inoculated into banana (Musa spp.) tissue culture plants can provide protection against banana weevils (Cosmopolites sordidus) and nematodes (Radopholus similis). The degree of control probably depends, in part, upon the level of endophyte establishmen...

The banana weevil Cosmopolites sordidus Germar, has evaded all efforts to manage it in all banana-based cropping systems except the commercial plantation banana system, where the 2 to 3 year crop cycle and the intensity of management limit the pest survival in that system. Conversely, in backyard...

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...
