Olfactory response of the predatory bug, Orius albidipennis to volatile blends of strawberry and cucumber infested by spider mite.
Herbivore induced plant volatiles (HIPV) that cause by plant because of pest feeding can affect on the searching behavioral response of natural enemies. We investigated the response of generalist predator Orius albidipennis Reut (Heteroptera: Anthocoridae) to volatiles from strawberry and cucumber leaves which infested with the spider mite Tetranychus urticae Koch (Acari: Tetranychidae) in Y-tube olfactometer under ambient laboratory conditions. Our results suggest that O. albidipennis is able to discriminate between volatiles emitted by infested plant versus uninfested plant and show the ability of predatory bugs to use odours related to prey presence to locate them.
