Factsheet of the month: April 2015 – Trapping banana weevils

Banana weevils factsheetAccording to the International Institute of Tropical Agriculture (IITA), Tanzania and Uganda, who produce almost half of all bananas in Africa, are only achieving 9% of their expected yield. This year sees the start of a 5-year project to develop high-yielding, pest resistant banana hybrids. Rony Swennen, the project’s leader, says that he hopes this will help to increase resistance to pests such as nematodes, Black Sigatoka and banana weevils. Banana weevils are found in virtually all banana-growing countries of the world and can cause severe damage to the banana plant. The weevils bore into the trunk and roots, which weakens the plants and can cause them to collapse altogether. This month’s Factsheet of the month explains how banana weevil populations can be reduced using traps made from 2 halves of a freshly cut banana stem.

 This factsheet was written by an agronomist from the Ministry of Agriculture in Kinshasa, Democratic Republic of the Congo. It is also available in French.
