Taste detection of the non-volatile isothiocyanate moringin results in deterrence to glucosinolate-adapted insect larvae

The non-volatile isothiocyanate moringin deterred larvae of the sawfly Athalia rosae and two Pieris species, and elicited response from a deterrent taste neuron in P. brassicae. Recovery of moringin applied to leaf discs for feeding assays was high.
