TI  - Low-temperature methyl bromide fumigation of emerald ash borer (Coleoptera: 
      Buprestidae) in ash logs.
PG  - 69-74
AB  - Ash (Fraxinus spp.) logs, infested with fully developed, cold-acclimated larval 
      and prepupal emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: 
      Buprestidae), were fumigated with methyl bromide (MeBr) at 4.4 and 10.0 degrees C 
      for 24 h. Concentrations X time dosages of MeBr obtained were 1579 and 1273 
      g-h/m3 (24-h exposure) at 4.4 and 10.0 degrees C after applied doses of 112 and 
      96 g/m3, respectively. MeBr concentrations were simultaneously measured with a 
      ContainIR infrared monitor and Fumiscope thermal conductivity meter calibrated 
      for MeBr to measure the effect of CO2 on Fumiscope concentration readings 
      compared with the infrared (IR) instrument. The presence of CO2 caused false high 
      MeBr readings. With the thermal conductivity meter, CO2 measured 11.36 g/m3 MeBr 
      per 1% CO2 in clean air, whereas the gas-specific infrared ContainIR instrument 
      measured 9.55% CO2 as 4.2 g/m3 MeBr (0.44 g/m3 per 1% CO2). The IR instrument was 
      0.4% as sensitive to CO2 as the thermal conductivity meter. After aeration, 
      fumigated and control logs were held for 8 wk to capture emerging beetles. No A. 
      planipennis adults emerged from any of the fumigated logs, whereas 262 emerged 
      from control logs (139 and 123/m2 at 4.4 and 10.0 degrees C, respectively). An 
      effective fumigation dose and minimum periodic MeBr concentrations are proposed. 
      The use of a CO2 scrubber in conjunction with nonspecific thermal conductivity 
      instruments is necessary to more accurately measure MeBr concentrations.
