| description | The beneficial effects of direct predation by zoophytophagous biological control agents
(BCAs), such as the mirid bug Nesidiocoris tenuis, are well-known. However, the benefits of
zoophytophagous BCAs’ relation with host plants, via induction of plant defensive responses, have
not been investigated until recently. To date, only the females of certain zoophytophagous BCAs
have been demonstrated to induce defensive plant responses in tomato plants. The aim of this work
was to determine whether nymphs, adult females, and adult males of N. tenuis are able to induce
defense responses in tomato plants. Compared to undamaged tomato plants (i.e., not exposed to the
mirid), plants on which young or mature nymphs, or adult males or females of N. tenuis fed and
developed were less attractive to the whitefly Bemisia tabaci, but were more attractive to the parasitoid
Encarsia formosa. Female-exposed plants were more repellent to B. tabaci and more attractive to
E. formosa than were male-exposed plants. When comparing young- and mature-nymph-exposed
plants, the same level of repellence was obtained for B. tabaci, but mature-nymph-exposed plants
were more attractive to E. formosa. The repellent effect is attributed to the signaling pathway of
abscisic acid, which is upregulated in N. tenuis-exposed plants, whereas the parasitoid attraction was
attributed to the activation of the jasmonic acid signaling pathway. Our results demonstrate that all
motile stages of N. tenuis can trigger defensive responses in tomato plants, although these responses
may be slightly different depending on the stage considered. |
