Timing and distribution of attack on East African highland banana (Musa AAA- EA) by the banana weevil, Cosmopolites sordidus (Germar), (Coleoptera: Curculion- idae) was studied in a field trial at a farm 25 km NE of Kampala, Uganda. Weevils were released at three densities (5, 20 and 40 females p...

Attraction of adult banana weevil, Cosmopolites sordidus to volatiles from banana pseudostem tissue and the synthetic pheromone Cosmolure+ presented singly or in combination, was studied in the laboratory and in the field. Olfactometric studies in the laboratory showed that 50 g of fermented bana...

Plantain (Musa AAB), a primary food crop in Ghana, is a key component in sustainable agricultural systems in high rainfall zones. Recently, there has been a substantial yield decline and reduction in plantation life. To elucidate the context in which intervention strategies should be developed, a...

Banana-weevil populations and associated damage were studied in adjacent plantations of highland cooking-bananas (cultivar Kibuzi) and introduced beer-bananas (cv. Kisubi) on a farm in central Uganda. Weevil density and mobility were assessed using mark and rerapture techniques. Residual banana c...
Beauveria bassiana is considered a virulent pathogen against the banana weevil Cosmopolites sordidus. However, current field application techniques for effective control against this pest remain a limitation and an alternative method for effective field application needs to be investigated. Three...

Banana (Musa spp.) is the most important food crop in Uganda as indicated by consumption rate, annual production (9.5 M t ha-1) and agricultural land committed to the crop. This level of productivity (6.3 t ha-1 yr-1) is extremely low when compared to the yields obtained on station and well-manag...
The effects of Radopholus similis and Pratylenchus goodeyi on growth, root health and yield of the East African highland cooking banana cultivar Mbwazirume (Musa AAA-group) were compared at Mbarara, Uganda, at 1430 m above sea level. In 3-year-old mats infected only with P. goodeyi, functional ro...

The banana weevil Cosmopolites sordidus (Germar) is an important pest on bananas and plantains (Musa spp.). Population build-up is slow and weevil problems become increasingly important in successive crop cycles (ratoons). Yield loss results from plant loss (death, snapping, toppling), mat disapp...

The banana weevil, Cosmopolites sordidus (Germar), is a nocturnal insect that is not readily observed in banana fields. Knowledge on its distribution is essential for the design of management strategies that target the adult stage. Marked weevils were released into seven-year-old banana plots. Te...
