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