Attraction ofHeliothis virescens (F.) (Lepidoptera: Noctuidae) to volatiles from extracts of cotton flowers.

Mated and virgin female and virgin male tobacco budworm moths,Heliothis virescens (F.), responded via directed upwind flight in wind-tunnel bioassays to volatiles from floral extracts of cotton,Gossypium hirsutum L. Significantly more male and female moths landed on cloth dispensers treated with a methylene chloride extract of debracted flowers than on control dispensers treated only with methylene chloride. Only mated females landed in significant numbers on the dispensers treated with extract of cotton squares, flowers (including bracts), or flower petals. After landing, most of the moths examined the dispensers by probing with their antennae, proboscis, and/or ovipositor.
