It was reported in the New York Times on May 21, 1967  that Dr. Orlo K. Jantz, a researcher at Michigan State University had stumbled upon a new way to control strawberry and picnic beetles. All that was needed was to set up traps baited with two colors of automobile paint. 

In his tests, the strawberry beetles were attracted to an acrylic primer – Dupli-Color DP-GM-3. and the picnic beetles to General Motors Midnight Blue DP-GM-44.

Jantz explained that if large numbers of the beetles could be drawn to traps sprayed with these colors, then the use of insecticides to treat crops could be greatly reduced.
