Abstract

Colored spheres of five different sizes (6.3, 8.9, 14.0, 16.5, 20.0 cm diam) and five colors (orange, black, yellow, green, white) were coated with a trapping compound and presented to field-caged flies (males, virgin females, mated females). The most females were captured on the 20 cm orange, green, and white balls and the 8.9 cm yellow ball. There was no statistically significant preference on the part of males for any particular size or color. When the four most attractive spheres were presented simultaneously to mated and virgin females they were most likely to be captured on 20.0 cm orange and green spheres. More males were caught on the 20.0 cm orange ball. When data were summed, 20.0 cm orange balls were statistically superior overall. In a field release test, 20.0 cm orange balls, 20.0 cm orange balls with a protein hydrolysate bait, 20.0 cm diam orange balls with caged live males, and 10 cm yellow balls with food bait were compared to McPhail traps baited with protein hydrolysate. The orange sphere with males was superior to all the other traps.
