Abstract
Although current USDA-APHIS standards suggest that a core temperature of 71.1°C (160°F) for 75 min is needed to adequately sanitize emerald ash borer,
Agrilus planipennis Fairmaire-infested firewood, it is unclear whether more moderate (and economical) treatment regimes will adequately eradicate emerald ash borer larvae and prepupae from ash firewood. We constructed a small dry kiln in an effort to emulate the type of technology a small- to medium-sized firewood producer might use to examine whether treatments with lower temperature and time regimes successfully eliminate emerald ash borer from both spilt and roundwood firewood. Using white ash (
Fraxinus americana L.) firewood collected from a stand with a heavy infestation of emerald ash borer in Delaware, OH, we treated the firewood using the following temperature and time regime: 46°C (114.8°F) for 30 min, 46°C (114.8°F) for 60 min, 56°C 132.8°F) for 30 min, and 56°C (132.8°F) for 60 min. Temperatures were recorded for the outer 2.54-cm (1-in.) of firewood.
