Attraction of Euwallacea nr. Fornicatus (Coleoptera: Curculionidae: Scolytinae) to Lures Containing Quercivorol

Euwallacea nr. fornicatus (Eichhoff) (Coleoptera: Curculionidae: Scolytinae) is an exotic ambrosia beetle that vectors fungal Fusarium spp. to avocados. Two field trials testing potential attractants to trap Euwallacea spp. were conducted in south Florida. Quercivorol + Ultra High Release Ethanol (URH) was the most powerful attractant for E. nr. fornicatus in the 2 field trials. In Florida, the populations of E. nr. fornicatus are small. The attractiveness of quercivorol lures to other Euwallacea spp. should be tested in conditions where population levels are greater as in California and Israel.
