Behavioral responses in prey location of the predatory stink bug, Eocanthecona furcellata, to chemical cues in the larvae of Spodoptera litura


, : Behavioral responses in prey location of the predatory stink bug, Eocanthecona furcellata, to chemical cues in the larvae of Spodoptera litura. Entomologia Experimentalis et Applicata 81(1): 91-96

Behavioral responses of the predatory stink bug Eocanthecona furcellata (Wolff) (Heteroptera: Pentatomidae) towards Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) larvae were observed in olfactometers. In single-and dual-tube olfactometers, adult bugs were observed to approach and stretch their proboscis toward the odor source. These types of behavior were also observed toward the control odor source in the dual-tube olfactometer. However, the frequency of these phases toward the control odor was significantly lower than that toward the odors from intact or dead larvae. The solvent extracts of larvae elicited these similar behavioral phases significantly more frequently and for significantly longer duration than the control. In a linear track olfactometer, E. furcellata nymphs were observed to be attracted to the fraction eluted with hexane from silica gel chromatography but proboscis-protruding behavior was not observed. The other fraction, 15%-ether-in-hexane from silica gel chromatography, elicited the proboscis-protruding behavior by a simple behavioral assay using a Pasteur pipette. These findings therefore indicate the presence of at least two different chemical cues in prey location.
