title: Effect of Lures and Colors on Capture of Lady Beetles (Coleoptera: Coccinellidae) in Tedders Pyramidal Traps.
abstract: Purposeful attraction and aggregation of adult Coccinellidae at target sites would be useful for sampling purposes and pest suppression. We field-tested 1) lures in yellow and black pyramidal traps and 2) pyramidal traps that had been painted one or two colors (without lures) to determine if lures or trap color affected capture of adult Coccinellidae. In only one experiment with lures did a single rate of limonene increase trap capture, whereas no other lure ever did. Yellow traps, regardless of using a lure, always captured significantly more lady beetles than black traps. When single-color red, orange, yellow, green, blue, purple, black, and white traps (without lures) were tested, yellow traps captured significantly more lady beetles. Of all species of Coccinellidae captured in these single-color traps, 95% were the exotic species Harmonia axyridis (Pallas) and Coccinella septempunctata L. H. axyridis alone dominated trap capture comprising 74.1% of all lady beetles. Two-color traps (yellow-green, yellow-orange, yellow-white, and yellow-black) never captured more than single-color yellow traps. These results demonstrate that yellow pyramidal traps can be used to purposefully attract, and when used without a collection device, possibly aggregate adult Coccinellidae at targeted field sites.
