Arthropod semiochemicals: mosquitoes, midges and sealice.

Signalling chemicals play an essential role in arthropod life cycles. They provide the means whereby mates, host and oviposition sites are located and recognized. The identification of such semiochemicals (sex pheromones, host location and habitat-related cues) in mosquitoes, midges and sealice of farmed salmon is revealing ways in which such devastating pests may be monitored and controlled by behavioural means using push-pull strategies to manipulate the pests away from hosts and into traps.
