<br/><br/> <br/><br/>ABSTRACT<br/><br/>The objective of this research is to report the occurrence of the nigra scale Parasaissetia nigra<br/>(Nietner, 1861) (Hemiptera: Coccidae) in mahogany (Khaya ivorensis) seedlings in a forest nursery<br/>in Mato Grosso state. In September 2017, the infestation was detected on the leaves and branches<br/>of the plants, causing injury and the death of the apical meristem and leaf curling symptoms.<br/>It was verified the symbiosis of P. nigra with ants, due to the sugary exudate. The chemical control<br/>was performed with insecticidal syrup and the proposed method was effective. This was the first<br/>reported occurrence of P. nigra on African mahogany in Brazil.<br/><br/>Keywords: african mahogany, nigra scale, forestry entomology.
