While testing traps baited with a blend of geranyl octanoate and geranyl butanoate (pheromone components previously identified for Agriotes lineatus, Coleoptera, Elateridae) in Portugal and Bulgaria, large numbers of the closely related Agriotes proximus were captured. In the literature, two different compounds, (E,E)-farnesyl acetate and neryl isovalerate had previously been identified as pheromone components of A. proximus. Subsequent field tests, conducted in several European countries, revealed that A. proximus was weakly attracted to geranyl butanoate on its own, while A. lineatus was weakly attracted to geranyl octanoate on its own. However, the largest catches for both species were observed with a blend of both compounds. No A. proximus was caught in traps baited with the blend of (E,E)-farnesyl acetate and neryl isovalerate at any of the test sites. In electroantennographic studies, antennae of male A. proximus and A. lineatus both gave greater responses to geranyl butanoate than to geranyl octanoate, suggesting that the perception of these two compounds was similar for both species. A 1:1 blend of geranyl octanoate and geranyl butanoate can be used as a bait in traps for the detection and monitoring of both A. lineatus and A. proximus in many European countries.
在葡萄牙和保加利亚用辛酸香叶酯和丁酸香叶酯（此前已确定为线角叩甲（鞘翅目，叩甲科）的信息素成分）混合诱饵测试诱捕器时，捕获了大量近缘的近线角叩甲。在文献中，两种不同的化合物，（E,E）-法尼醇乙酸酯和异戊酸橙花酯此前已被确定为近线角叩甲的信息素成分。随后在几个欧洲国家进行的田间试验表明，近线角叩甲对单独的丁酸香叶酯有微弱的吸引力，而线角叩甲对单独的辛酸香叶酯有微弱的吸引力。然而，两种化合物混合使用时，两种物种的捕获量最大。在任何测试地点，用（E,E）-法尼醇乙酸酯和异戊酸橙花酯混合物作为诱饵的诱捕器都没有捕获到近线角叩甲。在触角电位研究中，雄性近线角叩甲和线角叩甲的触角对丁酸香叶酯的反应都比对辛酸香叶酯的反应更强，这表明这两种化合物对两种物种的感知相似。在许多欧洲国家，辛酸香叶酯和丁酸香叶酯1:1的混合物可作为诱捕器中的诱饵，用于检测和监测线角叩甲和近线角叩甲。
