A field study was undertaken in Uganda using highland cooking banana (cv. Atwalira) to test the hypothesis that bananas grown under stressed conditions are more susceptible to attack by Cosmopolites sordidus (Germar). Four banana treatments were employed to create different levels of host-plant v...

The influence of crop management on banana weevil, Cosmopolites sordidus (Coleoptera: Curculionidae) populations and damage to highland cooking banana (cv. Atwalira) in Uganda
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
In Uganda, banana (Musa spp) and coffee (Coffea spp) form the economic base for a big population of small-scale farmers and provide environmental protection. However, their production is currently declining. The two crops are grown in association as intercrops or adjacent monocultures but little ...

Agronomic pests and economic factors influencing sustainability of bananacoffee systems of western Uganda and potentials for improvement
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...

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...

Experiments were carried out to evaluate various options to reduce wilting of bananas replanted to rehabilitate farms previously destroyed by Xanthomonas campestris pv musacearum (Xcm). Paring, time taken to cure paring injuries and covering corms with infested or uninfested soil were evaluated. ...
