Abstract

Food robbing is a special form of interference competition in ants. It has been frequently observed in Myrmecocystus mimicus, which waylay returning foragers of several Pogonomyrmex species at their nests and take insect prey, particularly termites, away from them. Myrmecocystus more successfully robs prey from P. desertorum and P. maricopa than from P. barbatus. Usually only those Pogonomyrmex nests are affected by Myrmecocystus prey robbing that are not farther away than 10 m from the Myrmecocystus nest. Some M. mimicus workers show a high specialization in prey robbing. Other cases of food robbing in ants are described.

摘要

食物掠夺是蚂蚁干扰竞争的一种特殊形式。在拟蜜蚁中经常观察到这种现象，拟蜜蚁会在几种收获蚁的巢穴处伏击归来的觅食者，并从它们那里夺走昆虫猎物，尤其是白蚁。与从巴氏收获蚁那里掠夺猎物相比，拟蜜蚁从沙漠收获蚁和马里科帕收获蚁那里更成功地掠夺到猎物。通常只有那些距离拟蜜蚁巢穴不超过10米的收获蚁巢穴会受到拟蜜蚁猎物掠夺的影响。一些拟蜜蚁工蚁在猎物掠夺方面表现出高度的专业化。文中还描述了蚂蚁食物掠夺的其他案例。
