Abstract
The reaction of the insect predators, Eupeodes corollae Fabr (Diptera, Syrphidae), Coccinella undecimpunctata L. and Hippodamiatredecimpunctata L. (Coleoptera, Coccinellidae) and Chrysoperla carnea (Steph.) (Neuroptera, Chrysopidae) was compared in response to odor and color of five flowers (Marigold, Calendula officinalis; Chamomile, Matricaria chamomilla; Fennel, Foeniculum vulgare Miller; Caraway, Carum carvi L and Marguerite,Chysanthemum coronarium L.) under laboratory conditions. The experimental tube indicated that the tested predators exhibited different degrees of attractiveness in response to flower colors and nectars of the tested plants. The nectar plant species of Chamomile and Fennel were significantly more attracted to E. corollae and Ch. carnea as compared to other tested species. C. undecimpunctata and H. tredecimpunctata exhibited the highest attractiveness to Marigold and Chamomile nectars. All predators exhibited the lowest preferability toward Marguerite and Caraway nectars. Preferability experiments illustrated that all tested predators exhibited the highest preferability to yellow flower colors (Fennel, Marigold and Chamomile) followed by white colors (Caraway). The present study evaluates the role of C. officinalis; M. chamomilla; and Chy. Coronarium flowers as supplemental food on the longevity and foraging behavior of the coccinellid predators, C. undecimpunctata and H.tredecimpunctata adult females. Flowers increased survival and searching rate in C. undecimpunctata and H. tredecimpunctata in comparison with prey diet-only treatments. This suggests that the availability of flowers of Marigoldand Chamomileas supplemental foods (pollen and nectar) in the field can serve to improve efficacy of coccinellid predators under conditions of prey limitation.
