Controlled studies to determine the efficacy of pseudostem trapping in reducing adult populations of the banana weevil, Cosmopolites sordidus (Germar), were conducted under farmer conditions in Ntungamo district, Uganda. Twenty-seven farms were stratified on the basis of C. sordidus population de...

Evaluation of pseudostem trapping as a control measure against banana weevil, Cosmopolites sordidus (Coleoptera: Curculionidae) in Uganda
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...

Survey of plant parasitic nematodes and banana weevil on Ensete ventricosum in Ethiopia
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...

Merging biotechnology with biological control: banana Musa tissue culture plants enhanced by endophytic fungi
Crop sanitation, i.e. destruction of crop residues, has been hypothesized to lower banana weevil damage by removing adult refuges and breeding sites. Although it has been widely recommended to farmers, limited data are available to demonstrate the efficacy of this method. The effects ...

Yield loss in highland banana caused by the banana weevil, Cosmopolites sordidus, was studied in field trials in Uganda. Weevils were released at the base of banana mats 9 months after planting. Weevil populations, corm damage, plant growth and yield were assessed over four crop cycles. The effec...

Damage by banana weevil, Cosmopolites sordidus (Germar), contributed to the decline and disappearance of highland cooking-bananas (Musa spp., type AAA-EA) from the central region of Uganda. Commercial growers in the southwest use chemical insecticides for the control of the weevil although resist...
