In field tests, we compared catches of papaya fruit flies, Toxotr1Jpana curvicauda Gerstaecker, on fruit model traps baited with dispensers releasing pheromone (2,6- methylvinylpyrazine) at different rates. Both male and female papaya fruit flies were attracted to traps baited with pheromone. Most were caught in the 2 h before dusk. Greatest numbers of both sexes were caught on traps with dispensers that released 12 male equivalents (approximately 960 ng/h). Patterns of catches of mated and unmated females over the range of pheromone release rates tested were different. High numbers of mated females were trapped at all release rates, indicating a strong visual response to the fruit model. Unmated females were more strongly attracted by the pheromone, with greatest catches occurring at a rate of 8 male equivalents.
