- Abstract
Caryocar brasiliense (Caryocaraceae), a tree characteristic of e Cerrado, is widely distributed and can reach a height of 10 meters with a six-meter-wide canopy. The objective of this study was to study the distribution of sucking insects (Hemiptera) and their natural enemies in the canopies of C. brasiliense trees in the Brazilian Cerrado. One rare, nine common, and one constant species of sucking insects and three rare, seven common, and four constant species of natural enemies were observed on C. brasiliense trees. The diversity, number of individuals, and species of Hemiptera and their natural enemies were similar in all four cardinal directions of branches of host trees. Abundance of the natural predators Crematogaster sp. (Hymenoptera: Formicidae) and Zelus armillatus (Hemiptera: Reduviidae) was highest on leaves of the east and north sides of the C. brasiliense trees, respectively. A large number of Crematogaster sp. was observed on C. brasiliense, with a predominance of Dikrella caryocar n. sp. (Hemiptera: Cicadellidae) and Pseudoccocus sp. (Hemiptera: Pseudococcidae) also being observed. The predators Trybonia sp. (Thysanoptera: Phlaeothripidae) and Chrysoperla sp. (Neuroptera: Chrysopidae) showed the highest numbers, while the number of D. caryocar n. sp. and Aphis gossypii (Aphididae) decreased, respectively, in comparison to the control. An increase in the number of sucking insects also increased the number of their natural enemies, and this differential distribution negatively influenced sucking insects. 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.
