The comparative response of Diabrotica species (Coleoptera: Chrysomelidae) to volatile attractants
Environmental Entomology 17 (4), 644-648
Abstract: Field tests conducted in a relict prairie using sticky traps baited with a broad range of adult diabroticine attractants showed Diabrotica cristata (Harris) shares some chemosensory responses with both D. barberi Smith and Lawrence and D. virgifera virgifera LeConte. D. cristata was attracted to estragole, ß-ionone, para-methoxycinnamaldehyde, and a mixture of trimethoxybenzene, indole, and cinnamaldehyde (=TIC mixture) (attractants for adults of D. virgifera virgifera in corn tests), as well as eugenol, isoeugenol, and cinnamyl alcohol (attractants for adults of D. barberi in corn tests). Several of the active compounds, such as cinnamyl alcohol and ß-ionone, are structurally distinct from the previously described eugenol-type attractants for D. barberi and D. cristata and represent new semiochemicals for the genus. In the prairie trials, D. barberi adults were anomalously attracted to two lures (estragole and the TIC mixture) that were not active in corn evaluations.
