First Record of Xylosandrus Compactus in Seedlings and Plantations of African Mahogany (Khaya Senegalensis) in Northeastern Brazil

The objective of this study was to report the first record of Xylosandrus compactus in a Khaya senegalensis plantation in the Northeast region of Brazil. The study area comprised 10 hectares of African mahogany ( Khaya senegalensis) planted under different silvicultural systems and varying in age (4, 10 and 24 months). From May to July 2019, both larvae and adults of Xylosandrus compactus, attacked the petiole of adult trees in the field, promoting small holes followed by darkening from the hole to the leaf tip. Furthermore, the stem of the seedlings at the nursery had holes in its stem basis and internal galleries in young and adult individuals. It is estimated that 77% of the Khaya senegalensis population in the 24-month trees were attacked. Therefore, the growth of the trees may be compromised, and if there is no proper management, X. compactus can cause economic damage in the K. senegalensis plantation.
