本文评估了开发和干扰对马里兰州[美国]林地中9种蚂蚁觅食行为的影响。这些物种在猎物的大小和类型上基本上重叠。三种类型的遭遇发生在物种之间的诱饵：攻击，避免和共存。锈色弓背蚁、异形蚁、硬鳞蚁和绢毛蚁为优势类群，桃金娘为优势类群。（M. punctiventris和M. emeryana）、Aphaenogaster rudis、Tapinoma sessile和Leptothorax curvispinosus的地位越来越低。下级物种显着减少进食时间时，在其他物种的存在。通过观察蚂蚁在诱饵处的活动，研究了该物种的开发能力。弯刺细胸蛛（Leptothorax curvispinosus）、红腹蛛（Aphaenogaster rudis）和蚁蛛属（Myrmica spp.）首先到达比Camponotus ferrugineus，这是在寻找新的食物来源显着较慢的诱饵的百分比。利用能力与干扰能力呈负相关，使下位种获得资源。在大多数情况下，诱饵定位的速度与诱饵到殖民地的距离无关。
This paper evaluates the effects of exploitation and interference on the foraging behavior of nine species of ants in a Maryland [USA] woodlot. These species overlapped substantially in both the size and type of prey taken. Three types of encounters occurred between species at baits: attacks, avoidance, and coexistence. Camponotus ferrugineus, Lasius alienus, Prenolepis imparis, and Formica subsericea fell into a dominant group, while the Myrmica spp. (M. punctiventris and M. emeryana), Aphaenogaster rudis, Tapinoma sessile, and Leptothorax curvispinosus were increasingly subordinate. Subordinate species significantly reduced feeding time when in the presence of other species. Exploitative abilities of the species were studied by observing ant activity at baits. Leptothorax curvispinosus, Aphaenogaster rudis, and the Myrmica spp. arrived first at a higher percentage of baits than did Camponotus ferrugineus, which was significantly slower at finding new food sources. An inverse correlation was found between exploitative and interference ability, which enabled the subordinate species to obtain resources. In most cases, the speed of bait location was not correlated with distance of the bait from the colony.
