Tree farmers in Uganda who have invested heavily in fast-growing eucalyptus trees face ruin because of an insect pest.
Believed to have come from Australia, the blue gum chalcid is causing damage to nursery seedlings as well as young and older trees.
Peter Kiwuso of the Forestry Resouces Research Institute recommends that the pest should be managed through biological controls rather than pesticides.
A survey is taking place to examine the extent of the infestation and damage which could cause a shortage of timber, poles and firewood.
