N2 - Behavioral responses of 4 species of natural enemies to 4 colors were examined by capturing adults on colored sticky cards placed at 2 locations (edge and interior) in corn, Zea mays L., fields. T2 - Coccinellidae), Chrysoperla carnea (Neuroptera: Chrysopidae), and Macrocentrus grandii (Hymenoptera: Braconidae) Trapped on Colored Sticky Traps in Corn Habitats T1 - Coleomegilla maculata, Coccinella septempunctata (Coleoptera The study suggests that, besides studying behavioral responses, color cards may be useful for monitoring natural enemy populations.", grandii, which is useful for determining whether its life cycle is synchronized with that of its host. It also revealed the pattern of adult flights of M. Captures on cards provided information on abundance of each natural enemy species during different periods in the summer. Few significant interactions were observed between the effects of color and those of location and height or habitat, which are perhaps indicative of microhabitat preferences. carnea, which was trapped equally on cards of all 4 colors. Compared with red, green, and white cards, yellow cards trapped greater numbers of all natural enemies, except C. Natural enemies studied included the coccinellids Coleomegilla maculata (DeGeer) and Coccinella septempunctata L., the chrysopid Chrysoperla carnea (Stephens), and Macrocentrus grandii Goidanich, a braconid larval parasitoid of Ostrinia nubilalis (Hbner). Cards were placed at 2 heights (1.8 and 0.3 m) in 1993 and in 2 habitats (sweet and field corn) in 1994, using a split-split plot design. The study suggests that, besides studying behavioral responses, color cards may be useful for monitoring natural enemy populations.Ībstract = "Behavioral responses of 4 species of natural enemies to 4 colors were examined by capturing adults on colored sticky cards placed at 2 locations (edge and interior) in corn, Zea mays L., fields.
