Volatile cues of enhanced attractiveness to Parapanteles hyposidrae (Wilkinson) wasps mediated by jasmonic and salicylic acid pathways synergism in tea plant

Abstract

The jasmonic acid (JA) and salicylic acid (SA) pathways are often thought to interact antagonistically in plants when mediating anti-herbivore resistance. However, we previously found that the two pathways in tea plant interact synergistically when treated with 1.5 mmol/L methyl jasmonate (MeJA) and 20 mmol/L SA at 12 h intervals (MeJA+SA treatment). Here, we investigated how and why JA-SA synergism in tea plants affected chemotaxis of Parapanteles hyposidrae (Wilkinson) wasps, the parasite of tea geometers.
