Weobserved higher numbers of bugs on Caryocar brasiliense (Malpighiales: Caryocaraceae) trees in the cerradothan in the pasture areas. The bugs were more abundant on leaves and branches than they were on fruits.The fruit production of Caryocar brasiliense was higher in the pastures than in the cerrado areas. Theabundance of bugs was affect positively by aluminum, organic matter, and tree height but was affectednegatively by soil pH. The productivity of C. brasiliense was correlated negatively with aluminum, pH, andnumber of bugs but was correlated positively with phosphorus and calcium. The number of eggs per clutchwas 14.3, the viability was 93% and the embryonic period was 6.9 days. We observed four nymphal instars,the sex ratio was 0.43, and the duration of the life cycle of E. rufomarginata was 156 days. We did not obtaineggs from the adults (F1), which indicated that the leaves were not a good food resource. A diverseenvironment and high plant crown structure favored populations of E. rufomarginata. The abundance of andthe damage caused by this insect indicate that E. rufomarginata is a potential pest on C. brasiliense trees. 2016 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303044042003 https://www.redalyc.org/journal/3030/303044042003/ https://www.redalyc.org/journal/3030/303044042003/html/ https://www.redalyc.org/journal/3030/303044042003/303044042003.epub https://www.redalyc.org/journal/3030/303044042003/movil en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
