Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae) is primarily an aphidophagous coccinellid species occurring in temperate areas of Central and South America (Vandenberg & Gordon, 1988). It has been reported as an efficient predator of aphids on cucumbers and chrysanthemums grown in glasshouses (Gurney & Hussey, 1970). Işıkber (1999) also reported that C. sanguinea would be a possible candidate for biological control of cotton aphid, Aphis gossypii Glover (Homoptera: Aphididae), in temperate glasshouses and would play an important role in reducing the populations of cotton aphid attacking field crops. Studies examining prey suitability for predators provide basic knowledge about which prey species supplies the necessary nutritional requisites for the predator, and also offer an explanation for success or failure of predators in biological control systems (Thompson, 1951). Several authors have examined the suitability of some aphid species for C. sanguinea. The brown citrus aphid, Toxoptera citricida (Kirkaldy) (Homoptera: Aphididae), was found to be an inadequate prey for the larvae of C. sanguinea as it prevented complete larval development, although it has been found feeding naturally on the brown citrus aphid (Morales & Burandt, 1985). On the other hand, Michaud (2000) recorded that C. sanguinea completed development and reproduced successfully on both T. citricida and Aphis spiraecola Patch (Homoptera: Aphididae), with shorter developmental times and heavier adult weights resulting from the T. citricida diet. The cotton aphid, A. gossypii, the black bean aphid, Aphis fabae Scop. (Homoptera: Aphididae), the peach-potato aphid, Myzus persicae (Sulzer) (Homoptera: Aphididae), and the vetch aphid, Megoura viciae Buckton (Homoptera: Aphididae) are important insect pests on many field crops, as well as some glasshouse crops and ornamental plants in temperate areas (Blackman & Eastop, 1984; van Schelt et al., 1990). As the ability of C. sanguinea to complete development and reproduce when feeding on these aphid species has not been examined before, this study was carried out to compare their suitability as food for C. sanguinea.
