| Abstract: | "Extracts obtained from hemolymph of sexually mature males of the Caribbean fruit fly Anastrepha suspensa contained four biologically important terpenoid components of the sex pheromone. The four components were identified as farnesene, bisabolene, anastrephin, and epianastrepin based on their relative retention indexes from capillary gas chromatography analysis, using both apolar and polar phase columns and their chemical ionization (isobutane) mass spectra. The ratio of the components in extracts of hemolymph was the same as the ratio present in the volatile blend of pheromone released by sexually mature males during the reproductive period. Studies conducted to determine the effect of age on amounts of these components in hemolymph indicated that they increased from undetectable levels on the day of adult emergence to maximum levels on day eight. The increases in amounts of the components present in hemolymph with increasing age were correlated with increases in amounts of volatile pheromone released by males. Time of day studies showed that the amounts of these components in hemolymph followed the daily pattern of release of volatile pheromone components. Other components of the sex pheromone including ocimene, (Z)-3-nonen-1-ol, (Z,Z)-3,6-nonadien-1-ol and suspensolide were not found in extracts of hemolymph. The data suggest that the hemolymph plays a role in the transport of these pheromone components during sexual signalling. Arch. Insect Biochem. Physiol. 42:225-232, 1999.
