Background. Aphids are one of the insect groups with the greatest impact on agricultural production. They affect a wide range of hosts, including fruit trees such as citrus. Objective. Identify the main morphological characters and evaluate a rearing protocol for the aphid Toxoptera aurantii Boyer de Fonscolombe, 1841 (Hemiptera: Aphididae) in a room-temperature in protected environment. Methodology. Specimens were collected from citrus trees in production in the province of Coclé, infested branches were cut and placed in plastic containers for transport. Insects were separated for identification through micro slides, observed under a microscope and identified using taxonomic reference keys. Four treatments were established with mucuna (Mucuna pruriens [L.] DC.), canavalia (Canavalia ensiformis [L.] DC.), bean (Phaseolus vulgaris L.) and orange jasmine (Murraya paniculata [L.] Jack) as host plants. Abundance was evaluated at 2 and 14 DAI. Data were analyzed by analysis of variance. For each treatment, 30 plants were used, and five aphids of different stages (two adults and three nymphs) were released on each plant. Plants were evaluated from 0 to 14 DAI (Days after infestation). Insect abundance was evaluated at 2 and 14 DAI. Data were analyzed by analysis of variance. Results. The morphological determinant characters of the species T. aurantii were identified. Statistically significant differences were observed between treatments (p |
