A no-choice wind tunnel olfactometer system for evaluating the attractiveness of plant volatiles to adult Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)
Entomologia Sinica 7 (3), 257-264
Abstract: A bioassay system to evaluate adult cotton bollworm (CBW), Helicoverpa armigera, behavioral responses to plant volatiles was described. The system was comprised of a no-choice olfactometer, a wind tunnel, and a wind tunnel room. The olfactometer was designed to provide for the testing and evaluation of volatiles from a variety of natural and synthetic sources. The behavioral responses in this system demonstrated that the volatiles of wilted leaves of Pterocarya stenoptera, Toona sinensis and Populus canadensis, the main materials of which poplar bundles were made, only could attract virgin females but not mated females and males. The volatiles emitted from fresh carrot and celery flowers did not exhibit significant attractiveness to both sexes of CBW. 0.1% phenylacetaldehyde showed significant attraction for virgin females and males. The biological significance of attraction of volatiles from these plants for CBW was discussed.
