The possibility of resistance development in the pharaoh's ant Monomorium pharaonis in regard to insecticides and chemosterilants in general and in the special case of sodium arsenate is discussed. The low number of sexuals and the long duration of generations reduced the possibility of the development of resistance in social insects to a great extent. Although the pharaoh's ant offers relatively good possibilities for the selection of resistance on account of the polygyny, the duration of generations in the range of a whole year under field conditions and the isogeny of the colonies diminished the development of resistance. Experimental investigations for the selection of resistance to sodium arsenate in laboratory colonies with artificially shortened sequence of generations are presented. Following six generations, no enlargement of tolerance or true resistance but a clear sensitivity could be stated. This sensitivity leads to an eradication of the colonies. It is pointed out, that in pharaoh's ant a development of resistance against the lethal action of sodium arsenate and carbaryl is impossible, because of the protection mechanism of the social food chain.
本文讨论了法老蚁（Monomorium pharaonis）对杀虫剂和化学不育剂产生抗性的可能性，特别探讨了其对砷酸钠的抗性情况。社会性昆虫中性蚁数量少且世代周期长，这在很大程度上降低了其产生抗性的可能性。尽管法老蚁因多雌制、野外条件下全年的世代周期以及蚁群的同质性，为抗性选择提供了相对较好的条件，但抗性发展仍受到抑制。文中介绍了在实验室蚁群中通过人工缩短世代序列来选择对砷酸钠抗性的实验研究。经过六代后，未发现耐受性增强或真正的抗性，反而表现出明显的敏感性。这种敏感性导致蚁群被根除。文中指出，由于社会食物链的保护机制，法老蚁不可能对砷酸钠和西维因的致死作用产生抗性。
