Evaluating the Effectiveness of Methyl Salicylate on Attracting Predators

Yaw-Jen Dong1 and Bei-Chen Hsiu1,*

Abstract

    The yellow sticky paper baited with different concentrations of methyl salicylate (MeSA) was field-tested for the effectiveness of attracting natural enemies in fruit orchards of the Taiwan Agricultural Research Institute during 2015–2016. The results showed that yellow sticky paper baited with MeSA significantly attracted more predators in Coccinellidae (99, 10, and 0.1% MeSA treatments, 2015–2016 full year), Chrysopidae (10, 1, and 0.1% MeSA treatments, 2015–2016 full year), Syrphidae (99, 0.1, and 0.01% MeSA treatments, 2015–2016 summer season), Anthocoridae (all MeSA treatments, 2015–2016 full year), Miridae (99, 10, 0.1, and 0.01% MeSA treatments, 2015–2016 full year), and Staphylinidae (99% MeSA treatment, 2015–2016 Spring season) than the control, but the attractions were varied with different concentrations and response of predators to different concentrations of MeSA was found variable in different seasons.

Key words: Methyl Salicylate, Predators, Biological Control.
