N2 - Damage to a host plant caused by insect herbivory and pathogens induces defence responses in the plant. Defence responses induced by hemipterans are often distinct from those elicited by chewing herbivores. Furthermore, hemipterans and pathogens induce a similar set of specific responses, which cannot only affect different species of insect herbivores, but also reduce the severity and symptoms of pathogen attack. Moreover, hemipteran predators can also induce plant resistance against insect herbivory, e.g. by probing/feeding attempts or via ovipositing into plant tissue. The aim of this review was to review only studies that involved direct induced resistance, induced by insects, such as hemipterans and predators, on subsequent attack by insect pests and pathogens. The criterion applied was that a reduced activity of the aggressors was measured, accompanied by direct defence responses. Studies on herbivore-induced plant volatiles (HIPVs) were excluded as our focus is on induced resistance that would also have effect on pathogens that cannot themselves respond to HIPVs. Out of a total of 375 studies generated by a systematic search, 24 studies fulfilled the criteria. The review shows that the release of hemipteran predators for biological control in greenhouses may also lead to induced resistance against subsequent attackers. Monitoring of hemipterans and plant diseases are used to inform early warning systems for pest management. Accordingly, a thorough understanding of the responses induced by hemipterans can facilitate further progress in crop protection strategies in both greenhouse facilities and in open field productions.
