Abstract:Recent advances in marking pheromones (MPs) in predatory insects and mites were reviewed. MPs have been widely documented in predators in Coleoptera, Neuroptera, Diptera, Hemiptera and Acarina. They mediate foraging, oviposition, cannibalism and intraguild predation in predators, change life history in aphids. As a result, MPs dramatically affect biological control. MPs are produced or stored in exocrine glands or digestive ducts in both larvae and adults, or may be directly secreted by eggs. Up to now, several MPs have been chemically identified. All of them are blends of alkanes. Several factors, such as MPs’ persistence, intrinsic (such as oviposition habit, age, experience or sex) and extrinsic factors (such as available preys), may affect the response of predators to MPs.
