Methyl anthranilate as an attractant for two thrips species and the thrips parasitoid Ceranisus menes

The role of floral scents in host location by flower-dwelling thrips and a thrips parasitoid was investigated by experiment in the field. The scent of methyl anthranilate significantly increased the catches of Thrips hawaiiensis, Thrips coloratus, and Ceranisus menes, but had no effect on Thrips tabaci. Anisaldehyde increased the catches of I: hawaiiensis and T tabaci, but had no such effect on I: coloratus and C. menes. Geraniol increased the catches of T hawaiiensis, but not of T coloratus, T. tabaci, or C. menes. Seasonal fluctuations of T. hawaiiensis, I: coloratus, and C. menes can be recorded by using methyl anthranilate as a lure for monitoring.
