What chemical attracts parasitic wasps?

The induced volatile compound, (Z)-3-hexenol, as the primary damage attractant for the host location by the leafminer parasitoid. It is widely known that parasitoid insects use induced volatile compounds from herbivore-damaged plants to locate their hosts [10], [36]–[37].
