Maredia, K. M., S. H. Gage, D. A. Landis, and T. M. Wirth. 1992. Visual response of Cocinella septempunctata (L.), Hippodamia parenthesis (Say) (Coleoptera: Coccinellidae), and Chrysioerua carnea (Stephens) (Neruoptera: Chrysopidae) to colors. Biological Control 2:253-256.
The response of the seven-spotted lady beetle, Coccinella septempunctata (L.) (Coleoptera: Coccinellidae), the parenthesis lady beetle, Hippodamia parenthesis (Say), (Coleoptera: Coccinellidae), and the green lacewing, Chrysoperla carnea (Stephens), (Neuroptera: Chrysopidae) to seven colors was evaluated in the field using sticky panels. C. septempunctata exhibited a strong positive response to yellow. C. carnea showed a preference for yellow, green, and red. H. parenthesis did not exhibit strong visual orientation to any color. Programs aimed at monitoring these predators should consider their visual responses to colors in designing monitoring systems.
