A Azmi, Toxicity of Melia azedarach (Bakayan) root extract (B-R) against ladybird beetle (Coccinella
septumpunctata Linn.) and estimation of cholinesterase activity in treated and untreated insects.
Caption: Both Coccinella
septempunctata (seven-spotted ladybird, far left) and Harmonia axyridis (multicolored Asian lady beetle, center) can produce greenness in wine when they are incorporated in with grapes during harvest (right).
Evidence for a material gradient in the adhesive tarsal setae of the ladybird beetle Coccinella
Here, we focus on Adalia and Coccinella
species pairs, because each of these genera contains generalist and specialist species pairs distributed sympatrically in Britain and other parts of Europe and considerable information is available about their ecology.

One species introduced to Alaska, Coccinella
septempunctata, has displaced native species in other agriculturally important areas of the United States (Wheeler and Hoebeke, 1995; Elliot et al., 1996; Alyokhin and Sewell, 2004).

The frugivory in coccinellid predators seems to be rare, but it has been documented for Coccinella
septempunctata Linnaeus, 1758 and Adalia bipunctata (Linnaeus, 1758) (HODEK et al., 2012); however, coccinellid predators were never considered a problem for agriculture of economic importance (GALVAN et al., 2008).
