Abstract The two major yeasts isolated from the southern pine beetle,Dendroctonus frontalis Zimmerman, areHansenula holstii Wickerham andPichia pinus (Hoist) Phaff; a third yeast,P. bovis van Uden et do Carmo-Sousa, has been isolated far less frequently. The main volatile metabolites produced by these yeasts are isoamyl alcohol, isoamyl acetate, 2-phenylethanol, and 2-phenylethyl acetate.We have found that certain of these compounds, particularly the esters, can greatly, enhance the attractiveness of a mixture of frontalin:trans-verbenol: turpentine (1:1:12), at certain limiting concentrations, to walking beetles in a laboratory bioassay.
