TI  - Semiochemicals Affecting Attraction of Ambrosia Beetle Euwallacea fornicatus 
      (Coleoptera: Curculionidae: Scolytinae) to Quercivorol: Developing Push-Pull

AB  - Euwallacea fornicatus (Eichhoff), the polyphagous shot hole borer (PSHB), is an 
      ambrosia beetle infesting avocado Persea americana Mill. limbs in North America 
      and Israel. We conducted field experiments with sticky traps in avocado orchards 
      to develop push-pull semiochemical methods of managing PSHB. Traps baited with 
      10-fold increasing doses (0.01 to 100x or 1.26 microg to 12.6 mg/d) of attractant 
      quercivorol were previously shown to increasingly capture female PSHB (males 
      flightless). We converted trap catch of this relationship to a standardized 
      effective attraction radius (EAR) that predicts capture power of baited-traps 
      regardless of insect flight density. Earlier, piperitone and verbenone were shown 
      to strongly inhibit attraction of PSHB to quercivorol-traps. We tested increasing 
      numbers of 1x piperitone dispensers at 0.75-m distance surrounding a 
      quercivorol-trap and found PSHB catch to decline exponentially. Increasing 
      decadic doses (0.01 to 10x) of either verbenone or piperitone released at 1x 
      quercivorol-traps caused a sigmoidal first-order kinetic-decay in catch. 
      Verbenone (1x) placed at increasing distances (0, 0.25, 0.5, 1, and 2 m) from a 
      1x quercivorol-trap became increasingly ineffective in reducing catch of PSHB. We 
      found no evidence that ethanol released from 7.5 to 480 mg/d affected attraction 
      of PSHB, but Scobicia chevrieri (Villa and Villa) (Coleoptera: Bostrichidae) was 
      increasingly attracted. Due to their relatively short-range (<0.5 m) inhibition 
      of attractive sources, piperitone, and verbenone dispensers should be placed on 
      avocado trunks where PSHB aggregations occur before the flight season.
