HYMENOPTERAN PARASITOIDS COLLECTED IN AN Eucalyptus grandis PLANTATION AND IN A NATIVE VEGETATION AREA IN IPABA, STATE OF MINAS GERAIS, BRAZIL

ABSTRACT

Composition and frequency of hymenopteran parasitoids were studied in an Eucalyptus grandis W. Hill ex. Maiden plantation and in a native vegetation area with 11 Malaise traps in a transect native vegetation-eucalyptus plantation from March 1997 to March 1998. A total of 2,099 individuals of nine superfamilies and 26 families of this group was collected. The family with the highest number of individuals was Ichneumonidae followed by Braconidae, Scelionidae and Eulophidae with 577, 452, 374 and 185 individuals. Higher number of parasitoids was collected in the vicinity and borders of the native vegetation what demonstrates that fragments of native vegetation intermingled with eucalyptus plantations can be recommended as a strategy for pest management in these plantations.
