The lethal heat treatment dose (time and temperature) for the prepupal life stage of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), emerald ash borer (EAB), was determined through an in vitro application using a carefully calibrated heat treatment apparatus. The lethal and sublethal effects of heat on A. planipennis prepupae were assessed through a ramped heat delivery application, simulating industrial kilns and conventional heat chamber operations, for treatments combining target temperatures of 54 °C, 55 °C, and 56 °C, and exposure durations of 0 min (i.e., kiln temperature ramp only), 15 min, or 30 min. Prepupal EAB larvae did not survive exposure to 56 °C for 15 min or longer, or to 55 °C for 30 min. Sublethal effects were observed for all other treatments. Sublethal effects included delayed development and failure to complete the pupal and adult life stages.
通过使用经过精确校准的热处理设备进行体外应用，确定了光肩星天牛（鞘翅目：吉丁甲科）蛹前期的致死热处理剂量（时间和温度）。通过模拟工业窑炉和传统加热室操作的升温加热应用，评估了热对光肩星天牛蛹前期的致死和亚致死效应，处理温度组合为54℃、55℃和56℃，暴露时间为0分钟（即仅窑炉温度升温）、15分钟或30分钟。蛹前期光肩星天牛幼虫在暴露于56℃ 15分钟或更长时间或55℃ 30分钟后无法存活。所有其他处理均观察到亚致死效应。亚致死效应包括发育延迟以及无法完成蛹期和成虫期。
