Conteúdo: 	The chemical composition of volatile oils from 22 genotypes of Citrus and related genera
was poorly differentiated, but chemometric techniques have clarified the relationships between
the 22 genotypes, and allowed us to understand their resistance to D. citri. The most convincing
similarities include the synthesis of (Z)--ocimene and (E)-caryophyllene for all 11 genotypes
of group A. Genotypes of group B are not uniformly characterized by essential oil compounds.
When stimulated with odor sources of 22 genotypes in a Y-tube olfactometer D. citri preferentially
entered the arm containing the volatile oils of Murraya paniculata, confirming orange jasmine as its
best host. C. reticulata, C. sinensis was the least preferred genotype, and is characterized by the
presence of phytol, (Z)--ocimene, and -elemene, which were not found in the most preferred
genotype. We speculate that these three compounds may act as a repellent, making these oils less
attractive to D. citri.
