First report of Hypsipyla grandella (Lepidoptera: Pyralidae) on African mahogany Khaya ivorensis

The mahogany shoot borer Hypsipyla grandella Zeller is an important economic pest in all American tropical forests, because it prevents monoculture of valuable timber trees species like mahogany and cedar. The shoot borer damages several tree structures, especially the apical shoots, impairing the formation of the commercial stem. This pest can attack the plants during the year and one larva per plant is enough to cause significant damage. In infested areas, the attack can reach up to 100 % of the trees. The Australian cedar and African mahogany have been cultivated in Brazil for timber production, because they are considered resistant to H. grandella (Lepidoptera: Pyralidae) attack. However, in this work we report for the first time the H. grandella attack to African mahogany Khaya ivorensis
