A new species of Dikrella is described and figured based on specimens from Minas Gerais, Southeastern Brazil. The new species is diagnosed by the process of pygofer and the general form of aedeagus. Adult males, females, and also nymphs were found on pequi tree, suggesting that Dikrella caryocar n. sp. has its full life cycle in this plant.

Cardinal distribution of sucking insects in Caryocar brasiliense (Caryocaraceae)in e Cerrado (Brazil)
The speed and direction of wind may have affected the distribution of sucking insects on different sides of C. brasiliense trees, as higher populations were found on the sides without prevailing winds.
Diversity of Hemiptera (Arthropoda: Insecta) and Their Natural Enemies on Caryocar brasiliense (Malpighiales: Caryocaraceae) Trees in the Brazilian Cerrado
Increasing diversity indices and numbers of species and individuals of sucking insects were followed by similar trends in the populations of natural enemies, and Aluminum level positively affected the number ofspecies and individuals, and the pH of the soil reduced those of sucking Insects.

Seasonal Abundance of Hemipterans on Caryocar brasiliense (Malpighiales: Caryocaraceae) Trees in the Cerrado
The increase in the numbers of individuals and species of predators were correlated with the reduction of these same ecological parameters of the sucking insects respectively and it is argued that this differential temporal distribution of sucking insects and their predators was influenced for phenology of plant and weather.
