Abstract:In the laboratory and in field cages, papaya fruit flies, Toxotrypana curvicauda Gerstaecker, responded optimally (short range attraction and landing) to visual stimuli characteristic of host fruit. The compound eyes of male and female papaya fruit flies were most sensitive to blue (475 nm) and green (500 nm) wavelengths when measured by electro-physiological methods. A fruit model (12.7 cm diameter, dark green sphere) was combined with synthetic sex pheromone (2,6-methylvinyl pyrazine) in a controlled release formulation, to make a trap for capturing papaya fruit flies in the field. Flies attracted by the pheromone landed on the sticky-coated fruit mimic and were caught. In a field test of the trap with different sex pheromone release rates, mostly females were caught. Catches of females were higher in traps releasing 140, 300, and 900 ng/h than in unbaited control traps. Males were caught in traps with all release rates of pheromone tested, but none significantly higher than in unbaited traps. This is only the second successful field test of sex-pheromone baited traps for fruit flies.
