Common bean (Phaseolus vulgaris L.) is the most important legume used for direct human consumption in Latin America, with an increasing expansion of cultivated areas in recent years. Here, we report the first occurrence of Conotrachelus quadrilineatus Champion, 1904 (Coleoptera: Curculionidae: Molytinae) feeding on bean in South America. Larvae and adults of C. quadrilineatus were observed during the first half of 2022, severely affecting the plantations of 20 bean farmers in the municipality of Garcia-Rovira, Santander Colombia. It is necessary to describe and quantify the damage of C. quadrilineatus in bean crops, as well as to study its bioecology.
菜豆（Phaseolus vulgaris L.）是拉丁美洲最重要的直接食用豆类，近年来种植面积不断扩大。在这里，我们报告了在南美洲首次发现豆象科（Coleoptera：Curculionidae：Molytinae）的四纹豆象 Conotrachelus quadrilineatus Champion，1904 取食菜豆。2022 年上半年观察到 C. quadrilineatus 的幼虫和成虫，严重影响了哥伦比亚桑坦德省加西亚-罗夫拉市 20 位菜豆种植户的种植园。有必要描述和量化 C. quadrilineatus 在菜豆作物中的损害，并研究其生物生态学。
