Detection of ultra-weak photon emission in sunflower (Helianthus annuus L.) infested by two spotted-spider mite, Tetranychus urticae Koch-research note

Abstract Sunflower production plays an important role in global industrial oil production. Two-spotted spider mite, Tetranychus urticae , is a dangerous, polyphagous arthropod pest with cosmopolitan distribution, which can endanger the economic features of sunflower It widely known that pests trigger various reactions host plants. Among these, detection ultra-weak photon emission (UPE) enhanced upon infestation novel, non-invasive method suitable for visualisation and monitoring both biotic abiotic stress living tissues. In present study, increase UPE triggered by caused T. Helianthus annuus was measured. response injured plants differed from control plants, reflected difference bioluminescence intensity. leaves attacked onset value average count detected sensor expressed cps (counts per second) one order magnitude higher on as compared to revealed uninjured leaves. Furthermore, infested resulted abrupt decrease intensity when assayed function time. The use this imaging technique has allowed injury induced stressor.
