在实验室和野外测定了两种白蚁对巴基斯坦10种木制品和家具常用木材的自然抗性和取食偏好。为测试巴基斯坦常用木材的天然耐受性，进行了选择性和非选择性实验室和田间试验。在非选择性的实验室和田间试验中，冷杉的抗性最强，欧美杨的抗性最低。在实验室和野外的选择性摄食试验中，查氏田鼠被提供了两种木材的组合，但查氏田鼠表现出与非选择性摄食试验相同的摄食偏好。黑脉金线虫的取食偏好和木材消耗率不同于白纹伊蚊。刺梨最不受欢迎，欧亚锦鸡儿最受欢迎。比较黄杨的木材消耗率，黑皮黄杨的木材消耗量大于黄杨。还研究了干燥温度(60℃、70℃、80℃、90℃和100℃)对木材试件的影响，发现木材消耗量随着温度的升高而增加。在实验结束时，香茅木材标本的偏好度从大到小排列为：欧洲杨；印扎；雪松；刺杉；白桑；大树；芒果；阿拉伯相思；西方刺杉；冷杉。10种木材对黑星天牛的抗性排序为：欧洲杨；芒果；冷杉；华山松；白皮松；黄檀；相思；印扎；雪松；大红柏。两种白蚁对10种木材的木材消耗率的田间研究证实了实验室评价的结果。
Natural resistance and feeding preferences of two termite species, Coptotermes heimi and Microcerotermes championi, for ten species ofwoods commonly used in wood work and furniture in Pakistan were tested in the laboratory as well as in the field. Both choice and no-choice laboratory and field experiments were conducted to test the natural resistance of timbers commonly used in Pakistan. For M. championi, in no-choice laboratory and field tests, Abies pindrow was found to be most resistant and Populus euramericana was least resistant. In choice feeding tests, both in the laboratory and field, M. championiwere offered a combination of two woods, but M. championi showed the same feeding preference as in no-choice feeding tests. For C. heimi, the feeding preferences and wood consumption rate was different from that of M. championi. Tectona grandis was found to be least preferred for C. heimi and P. euramericana was the most preferred. When wood consumption rate of P. euramericana was compared, C. heimi consumed more P. euramericana than M. championi. The impacts of drying temperature (60°C, 70°C, 80°C, 90°C and 100°C) on wood specimens were also studied and it was seen that the amount of wood consumed increased with the increase in temperature. At the end of the experiment, for M. championi, the wood specimens were arranged in the following descending order of preference: Populus euramericana > Azadirachta indica > Cedrus deodara > Pinus roxburghii > Morus alba > Tectona grandis > Mangifera indica > Acacia arabica > Thuja occidentalis > Abies pindrow. The ranking of the resistance of the ten woods against C. heimi (Wasmann) were Populus euramericana > Mangifera indica > Abies pindrow > Pinus wallichiana > Morus alba >Dalbergiasissoo > Acacia nilotica > Azadirachta indica > Cedrus deodara > Tectona grandis. Field studies on wood consumption rate of 10 wood species by two termite species, C. heimi and M. championi, confirmed the findings from laboratory evaluation.
