The occurrence of Hypsipyla shoot borer on species of exotic Meliaceae planted in the Northern Territory.

African mahogany Khaya senegalensis is the favoured species for high-value plantations in the Top End of the Northern Territory because it has outperformed others in extensive trials over 40 years. Despite its vigour, Khaya is characterised by poor form that may be related to its genetics, nutrition or chronic low level pest attack. However few pests and diseases have been recorded locally for Khaya or the other species tested.
