Kairomones are inter-specific semiochemicals which mediate interactions beneficial to organisms that detect them. The use of kairomones for biocontrol of insect pests has been of interest for several decades due to the fundamental importance of host-plant selection by phytophagous insects, as well as the potential of natural enemies to co-opt those processes in ensuring their own survival. Pest management efforts that enhance the effectiveness of natural enemies can reduce economic loss and negative effects of insect herbivory. However, biocontrol agents often are unable to manage the populations of insect pests satisfactorily, due to limited host-searching capacity and limited detection range of 'signals' from damaged host plants. Here, we discuss known successful examples of such semiochemicals, kairomones, and their ultimate potential for biological control. Elsevier Ltd.
