Abstract
Aphis craccivora Koch, 1854 (Hemiptera: Aphididae) is a highly polyphagous aphid that is considered a pest of many crops with economic interest. The present study reports the occurrence and plant damages caused by the aphid A. craccivora on mahogany seedlings (Swietenia macrophylla King, Meliaceae) and scarlet jade vines (Mucuna bennettii F. Muell., Fabaceae) in the Distrito Federal, Brazil. Infestations of this aphid were found in twelve mahogany seedlings and two scarlet jade vines. The infestations caused deformations in the young leaflets of mahogany plants as well as leaves and inflorescences of scarlet jade vine. A. craccivora negatively affected the development of S. macrophylla and might become a limiting factor for seedlings production.

The present study reports the occurrence and plant damages caused by the aphid Aphis craccivora Koch, 1854 (Hemiptera: Aphididae) on mahogany seedlings and scarlet jade vines in the Distrito Federal, Brazil
The aphids collected in mahogany and red jade were fixed in Falcon® tubes containing 70% alcohol, subsequently mounted on microscope slides, following the methodology described by Ilharco & Gomes (1981) and identified with the aid of a microscope using a taxonomic key proposed by Holman (1974)
Summary
Mahogany (Swietenia macrophylla King, Meliaceae) from the Amazon has wood with high commercial value. Pests and diseases can negatively affect the development of plants, hampering production and making the use of some seedlings impossible. Some arthropods have been observed to damage young mahogany plants, including scale insects and mites (Castro et al 2018; 2019a; 2019b; 2020).
