Abstract
ABSTRACT Caryocar brasiliense Camb. (Malpighiales: Caryocaraceae) trees have a wide distribution in the Cerrado, a tropical Brazilian savanna, with high diversity and endemism. This plant is protected by federal laws and is untouched in deforested areas of the Cerrado. This situation increases the damage to leaves from galling insects (Hymenoptera). We studied populations of galling insects and their natural enemies on C. brasiliense trees for 3 successive yr during each season in the Cerrado. A globoid gall-inducing Eurytoma sp. (Hymenoptera: Eurytomidae) and its parasitoid Sycophila sp. (Hymenoptera: Eurytomidae) adults and predator Zelus armillatus (Lepeletier and Serville) (Hemiptera: Reduviidae) on the leaves were most abundant in the winter. The numbers of vein galls correlated negatively with the numbers of discoid and spherical galls, and the numbers of spherical galls correlated negatively with the numbers of discoid galls on C. brasiliense leaflets. Increased percentages of defoliation were corr...
