将老的房屋蛀虫幼虫Hylotrupes bajulus放入红橡木（Quercus spp.）在70%的含水量（MC），黄杨（鹅掌楸）在7%的MC，和南方黄松（松属）在12%或23%的MC下;将木片插入施加真空（20 mm Hg，20°C）的柔性容器中。幼虫死亡是由于幼虫体内水分流失，导致全身脱水。幼虫被发现在体重减轻25%至60%时死亡。在黄杨和松木片上的幼虫在96小时内被杀死。致死真空时间与木材含水量和幼虫体重有关。在这项研究中，木材MC越低，幼虫死亡所需的时间越少。
Old house borer larvae, Hylotrupes bajulus, were placed into pieces of red oak (Quercus spp.) at 70 percent moisture content (MC), yellow-poplar (Liriodendron tulipifera) at 7 percent MC, and southern yellow pine (Pinus spp.) at MCs of 12 percent or 23 percent; the wood pieces were inserted in a flexible container to which vacuum (20 mm Hg at 20°C) was applied. Larval mortality was the result of loss of larva body water, which resulted in whole-body dehydration. Larvae were found dead at body weight losses ranging from 25 to 60 percent. Larvae were killed in less than 96 hours in the pieces of yellow-poplar and pine wood. Lethal vacuum time was related to wood MC and larval weight. In this study, the lower the wood MC, the fewer hours required for larval mortality.
