The article conveys some information:
Herbivorous insects are important problems in cranberry (Vaccinium macrocarpon Ait.) production The use of chem. pesticides is common practice, but beneficial insects such as natural enemies of herbivores (e.g. predators and parasitoids) could be affected as well. Therefore, we studied the defensive mechanisms that cranberry plants use to combat pests, focusing on herbivore-induced plant volatiles (HIPVs), which can be used to recruit predators and parasitoids foraging for prey or hosts. The results showed that different cranberry genotypes vary in their emission of monoterpenes and sesquiterpenes but not in their expression of two genes associated with terpene biosynthesis, α-humulene/β-caryophyllene synthase and (3S,6E)-nerolidol/R-linalool synthase. Induction with Me jasmonate or herbivore (gypsy moth, Lymantria dispar L.) feeding increased the expression of these genes and emission of HIPVs. The HIPV Me salicylate (MeSA), alone or in combination with other HIPVs, increased syrphid attraction by 6-fold in the field, while (Z)-3-hexenyl acetate and MeSA repelled ladybeetles and megaspilids, resp. Linalool and β-caryophyllene elicited no behavioral responses of natural enemies. Elucidating the mechanisms of pest resistance, as well as exptl. augmenting plant defenses such as HIPVs, may contribute to the development of more sustainable pest management practices in crops, including cranberries. In addition to this study using Methyl Salicylate, there are many other studies that have used Methyl Salicylate(cas: 119-36-8Formula: C8H8O3) was used in this study.
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.Formula: C8H8O3
