Yang, Jun-Nan; Wei, Jia-Ning; Kang, Le published an article in 2021. The article was titled 《Feeding of pea leafminer larvae simultaneously activates jasmonic and salicylic acid pathways in plants to release a terpenoid for indirect defense》, and you may find the article in Insect Science.Recommanded Product: Methyl Salicylate The information in the text is summarized as follows:
The pea leafminer, Liriomyza huidobrensis, is an important pest species affecting ornamental crops worldwide. Plant damage consists of oviposition and feeding punctures created by female adult flies as well as larva-bored mines in leaf mesophyll tissues. How plants indirectly defend themselves from these two types of leafminer damage has not been sufficiently investigated. In this study, we compared the indirect defense responses of bean plants infested by either female adults or larvae. Puncturing of leaves by adults released green leaf volatiles and terpenoids, while larval feeding caused plants to addnl. emit Me salicylate and (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene (TMTT). Puncturing of plants by female adults induced increases in jasmonic acid (JA) and JA-related gene expressions but reduced the expressions of salicylic acid (SA)-related genes. In contrast, JA and SA and their-related gene expression levels were increased significantly by larval feeding. The exogenous application of JA+SA significantly triggered TMTT emission, thereby significantly inducing the orientation behavior of parasitoids. Our study has confirmed that larval feeding can trigger TMTT emission through the activation of both JA and SA pathways to attract parasitoids; however, TMTT alone is less attractive than the complete blend of volatiles released by infested plants. In the experiment, the researchers used Methyl Salicylate(cas: 119-36-8Recommanded Product: Methyl Salicylate)
Methyl Salicylate(cas: 119-36-8) is a natural herbivore-induced plant volatile. It is a naturally occurring product in trees, legumes, exotic plants, vegetables, berries, and the primary constituent of the oil of wintergreen.Methyl Salicylate is produced from salicylic acid.Recommanded Product: Methyl Salicylate
