[Identification and electroantennal olfactory and behavioral tests of hindgut-produced volatiles of the red turpentine beetle, Dendroctonus valens LeConte (Coleoptera : Scolytidae)]
Acta Entomologica Sinica 47 (6), 695-700
Abstract: An exotic invasive pine pest, red turpentine beetle, Dendroctonus valens LeConte (Scolytidae), was studied. GC-MS analysis confirmed the existence of verbenol and verbenone as well as the host volatiles (alpha-pinene, ß-pinene, 3-carene, myrcene and limonene) in hindguts of the beetle. Verbenol, verbenone and 3-( + )-carene, the most effective attractant in field test, all elicited electroantennal responses in EAG (electroantennogram) test. Indoor olfactory tests with a Y-type tube were conducted. Verbenone was attractive to D. valens at 1 µL/mL; and its effect could parallel that of 3-carene; however, 100 µL/mL of verbenone was somehow repellent to the beetle. Verbenol was repellent to D. valens in all dosages.
