Does the satiation hypothesis account for the differences in efficacy of coccidophagous and aphidophagous ladybird beetles in biological control? A test with Adalia bipunctata and Cryptolaemus montrouzieri
BioControl 47 (5), 537-543
Abstract: Mills (1982) formulated the satiation hypothesis in order to explain why ladybirds are generally more effective in the biological control of coccids than of aphids: aphidophagous ladybirds are supposedly less efficient because they become more rapidly satiated than coccidophagous ladybirds. If this is true, the former should spend less time eating than the latter. This hypothesis is tested in this study using the coccidophagous Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) and the aphidophagous Adalia bipunctata (L.) (Coleoptera: Coccinellidae). Contrary to Mills' (1982) prediction the coccidophagous ladybird did not feed continuously and even spent less time feeding than the aphidophagous ladybird. Furthermore, the gut capacity of C. montrouzieri is smaller than that of A. bipunctata.
