甜樱桃寄主品种对甲基溴在6℃和12℃下的敏感性不受寄主品种的影响。‘冰’和‘雷尼尔’樱桃幼虫的95%LC_(50)和LC_(90)在两种温度下的熏蒸试验中都有重叠。在比较药效研究中，两个品种对甲基溴的吸收率都很高(‘冰’和‘雷尼尔’樱桃在两种熏蒸温度下的平均吸收率分别为51.0%和55.5%)。在确认试验中，用g/m~3的甲基溴在6°C下熏蒸2小时，在‘Rainier’樱桃中估计的10,839只三龄幼虫都没有存活下来。这些结果表明，先前批准的甲基溴熏蒸计划对‘Bing’樱桃和其他甜樱桃品种的幼虫有同样的效果。
Susceptibility of third-instar codling moth, Cydia pomonella (L.), to methyl bromide at 6 or 12°C was not significantly affected by the host cultivar of sweet cherry. The 95% CL for the LC50 and LC90s for larvae in ‘Bing’ and ‘Rainier’ cherries overlapped in fumigation tests at either temperature. Sorption of methyl bromide by both cultivars in comparative efficacy studies was substantial (averaging 51.0 and 55.5% for ‘Bing’ and ‘Rainier’ cherries, respectively) for both fumigation temperatures. None of the estimated 10,839 third-instar codling moth treated in ‘Rainier’ cherries in a confirmation test survived fumigation with methyl bromide at 64 g/m3 for 2 h at 6°C. These results showed that methyl bromide fumigation schedules previously approved against codling moth larvae in ‘Bing’ and other sweet cherry cultivars are equally effective against codling moth larvae in ‘Rainier’ cherries.
