Abstract
Aphidophagous species of ladybirds have generally proved ineffective b iocontrol agents, whereas many coccidophagous species have proved very effective, especially Rodolia cardinalis (Caltagirone & Doutt, 1989). Two hypotheses have been proposed to account for this pattern: the op timum food utilization/satiation hypothesis (Mills, 1982) and the gene ration time ratio hypothesis (Kindlmann & Dixon, 1996). In this paper the extensive literature on ladybirds is used to test these hypotheses .
