UV-C irradiation is known to enhance plant resistance against insect pests. In the present study, we evaluated effects of low doses on Macrosiphum rosae infesting greenhouse rose (Rosa x hybrida) plants. The application 2.5-kJ/m2 leaves before infestation induced anti-herbivore and negatively affected aphid fecundity. No eggs first instar nymphs were recorded irradiated leaves, whereas an avera...
