We investigated the use of termite baiting, a proven system of targeted colony elimination, in an overall area-wide control strategy against subterranean termites. At two field sites, we used microsatellite markers to estimate the total number of colonies, their spatial partitioning, and breeding structure. Termite pressure was recorded for two years before and after the introduction of Trelona (active ingredient novaluron) to a large area of one of the sites. Roughly 70% of the colonies in the treatment site that were present at the time of baiting were not found in the site within two months after the introduction of novaluron. Feeding activity of the remaining colonies subsequently ceased over time and new invading colonies were unable to establish within this site. Our study provides novel field data on the efficacy of novaluron in colony elimination of as well as evidence that an area-wide baiting program is feasible to maintain a termite-free area within its native range.
我们研究了在针对地下白蚁的全面区域控制策略中使用白蚁诱饵（一种经过验证的有针对性的蚁群消灭系统）的情况。在两个野外地点，我们使用微卫星标记来估计蚁群的总数、它们的空间分布和繁殖结构。在其中一个地点的大片区域引入Trelona（有效成分虱螨脲）之前和之后的两年里，记录了白蚁压力。在引入虱螨脲后的两个月内，处理地点在诱饵投放时存在的大约70%的蚁群在该地点未被发现。随着时间的推移，其余蚁群的取食活动随后停止，并且新的入侵蚁群无法在该地点建立。我们的研究提供了关于虱螨脲在消灭蚁群方面功效的新的野外数据，以及有证据表明全面诱饵计划在其原生范围内维持无白蚁区域是可行的。
