Microcerotermes diversus Silvestri (Isoptera: Termitidae), an important pest in Ahwaz (Khouzestan, Iran), causes serious economic damage to wooden products in buildings. In this study, we determined the foraging populations and territories of this species using mark-release-recapture techniques. Based on both the weighted mean model and Lincoln index methods, mean termite foraging population estimates for two colonies, A and B, were 2,984,489 +/- 258,802 and 326,134 +/- 8,713, respectively. Estimates with the Lincoln index were 2,731,229 +/- 813,081 for colony A and 321,493 +/- 138,499 for colony B. Estimated horizontal foraging territories for colonies A and B were 25.59 and 44.16 m2, respectively. The maximum and minimum linear foraging distances were 5.40 and 2.14 m for colony A and 9.14 and 1.86 m for colony B, respectively. Our data expand the knowledge about the biology, ecology and behavior of M. diversus.
双叉异翅白蚁（Silvestri）（等翅目：白蚁科）是阿瓦士（胡齐斯坦省，伊朗）的一种重要害虫，它会对建筑物中的木制品造成严重的经济损失。在这项研究中，我们使用标记释放再捕获技术来确定该物种的觅食种群和领地。基于加权平均模型和林肯指数方法，两个群体 A 和 B 的白蚁觅食种群估计平均值分别为 2,984,489 +/- 258,802 和 326,134 +/- 8,713。A 群体的林肯指数估计值为 2,731,229 +/- 813,081，B 群体的林肯指数估计值为 321,493 +/- 138,499。A 群体和 B 群体的估计水平觅食领地分别为 25.59 和 44.16 m2。A 群体的最大和最小线性觅食距离分别为 5.40 和 2.14 m，B 群体的最大和最小线性觅食距离分别为 9.14 和 1.86 m。我们的数据扩展了对双叉异翅白蚁的生物学、生态学和行为的了解。
