Ovipositing Orius laevigatus increase tomato resistance against Frankliniella occidentalis feeding by inducing the wound response
Arthropod-Plant Interactions 5 (1), 71-80
Abstract: The anthocorid predator Orius laevigatus is widely used as biological control agent of thrips pests, including the western flower thrips Frankliniella occidentalis. In the current study, it was shown that O. laevigatus adults can increase plant resistance to feeding damage of F. occidentalis on tomato plants. The predator elicits a jasmonic acid (JA) mediated wound response during endophytic oviposition, resulting in reduced thrips feeding. A strong accumulation of H₂O₂, a molecule involved in different parts of the wound response, in leaf tissue surrounding the predator eggs or oviposition puncture sites was observed. Infestation of tomato plants with adult predators led to the upregulation of three JA regulated wound responsive genes: the precursor prosystemin, the jasmonic acid biosynthesis enzyme allene oxide synthase and the defence protein proteinase inhibitor I. Likewise, the presence of adults caused accumulation of proteinase inhibitor II, a principal marker for the wound response.
