A trial to determine yield losses in East African highland banana (cv. Atwalira) to banana weevil was run between 1994 and 2001 at the International Institute of Tropical Agriculture's Sendusu Farm in Namulonge, Uganda. Banana weevil adults were released into weevil-infestation plots, while weevi...

The effects of banana weevil, Cosmopolites sordidus (Germar) damage on highland banana growth, yield and stand duration in Uganda
Low soil fertility and pest pressure are two causes of the decline in banana (Musa AAA) production in central Uganda. Foliar analysis by the Diagnosis and Recommendation Integrated System (DRIS) pinpoints K and Mg as the most limiting nutrients. This study tested the effects of K and Mg additions...

Field studies were conducted to determine banana weevil attraction to processed banana tissues that could then be used at delivery sites for the entomopathogen Beauveria bassiana . Tested materials included pounded corm or pseudostem and chopped corm or pseudostem of (cv Mpologoma, AAA-EA and Kay...

Kairomone trapping system for delivery of Beauveria bassiana to control the banana weevil
Candidate strains of the fungus Beauveria bassiana have been identified for the intergrated pest management of the banana weevil (Cosmopolites sordidus). However, the important limiting factor has been the lack of an economic and effective delivery system to maximize field effects. Catches in phe...

Laboratory trials were conducted in Uganda at the Kawanda Agricultural Research Institute to determine attraction, eclosion success and larval survivorship of the banana weevil Cosmopolites sordidus (Germar) on crop residues of different ages. In the first experiment, studies focused on different...

Influence of plant and residue age on attraction, acceptance and larval survival of the banana weevil Cosmopolites sordidus (Coleoptera: Curculionidae)
The banana ( Musa spp.) weevil ( Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) is a major pest in East Africa causing yield losses of up to 14 metric tonnes per hectare annually. Laboratory and field experiments were conducted to determine whether the response of the banana weevil, C...

Effect of age, female mating status and density on the banana weevil response to aggregation pheromone
In Uganda, highland banana yields (5-30 t ha-1yr-1) are low in comparison to potential yields (70 t ha-1yr-1) due to high pest and disease pressure, soil fertility decline, and poor management. Although it is generally accepted that soil exhaustion is a major cause of low and declining yields, th...

Major constraints to banana (Musa spp., genome group AAA) production, a dietary staple for over 70 million people in sub-Saharan Africa, are pest infestations, poor nutrition and inadequate water. Although mulch can improve soil water and nutrient status, many farmers believe it also promotes the...
