Review: chemical ecology of ladybird beetles.Original Title Synthese bibliographique: l'ecologie chimique des coccinelles.

摘要

This paper reviews the chemical ecology of ladybird beetles (Coleoptera: Coccinellidae) to present the role of semiochemicals involved in plant-ladybird, prey-ladybird and predator-ladybird interactions. Ladybird beetles use these compounds to locate their prey, mate, protect themselves from predation or cannibalism, find a shelter to overwinter or ensure a better survival for their offspring. Thorough studies on ladybird behaviors towards these compounds could lead to their practical implementation in integrated strategies using ladybirds to control pests, like aphids or mealybugs.
