| description | European pear psylla, <i>Cacopsylla pyri</i>, is one of the worst pests of pear in Europe. We investigated whether acibenzolar-S-methyl (ASM) application on pear plants might affect the behaviour in <i>C. pyri</i>. The elicitor was applied on pear potted plants, and after 48 h, we confirmed the ASM-mediated induction of several Pathogenesis-Related protein (<i>PR</i>) coding genes. At the same time, an in-depth analysis was performed on the probing behaviour of adults and nymphs of <i>C. pyri</i> on ASM-treated pear plants by the EPG-DC system, as well as the assessment of young nymphs’ survival 7 days after the ASM application. The elicitor application weakly interfered with <i>C. pyri</i> nymphs probing behaviour and survival, while it did not affect adult stages. These data confirm previous observations obtained on <i>C. pyricola</i> and suggest that the elicitor does not represent a viable tool in the control of pear psylla species, especially if used alone, but it might be used in integrated management strategies focused on other plant pathogens such as <i>Erwinia amylovora</i>. |
