The behavioral and electrophysiological responses of nonirradiated male and female Anastrepha ludens (Loew) (Diptera: Tephritidae), to white sapote, Casimiroa edulis Oerst. (Rutaceae), volatiles were investigated. Females ßew upwind and landed more often on fruit than on artiÞcial fruit in wind tunnel bioassays. Males ßew upwind (but not landed) more frequently on fruit than on artiÞcial fruit. Porapak Q volatile extracts of white sapote also elicited upwind ßight and landing on artiÞcial fruit for both sexes. Gas chromatography-electroantennographic detection analysis of white sapote extracts revealed that antennae of both sexes responded to eight compounds. Two peaks were unidentiÞed because they did not separate from the solvent. Subsequent peaks were identiÞed by gas chromatography-mass spectrometry as styrene, myrcene, 1,2,4-trimethylbenzene, 1,8-cineole, and linalool in a proportion of 50: 21: 0.5: 27: 1.5, respectively. Eight peaks were tentatively identiÞed as -trans-ocimene. The number of A. ludens captured in multilure traps baited with the synthetic white sapote blend was higher than the ßies captured by the multilure unbaited traps (control) in Þeld cages. However, the number of ßies captured by traps baited with the white sapote blend was not different from that of ßies captured by traps baited with hydrolyzed protein. Using standard chemical ecology techniques, we found potential attractants from wild sapote fruit for monitoring and management of A. ludens population.
