在高度社会化的蜜蜂中，蜂王下颌信息素（QMP）对蜂群生活至关重要。中华蜜蜂（Ac）和意大利蜜蜂（Am）都有一组进化上保守的QMP化合物：（E）-9-氧代癸-2-烯酸（9-ODA）、（E）-9-羟基癸-2-烯酸（9-HDA）、（E）-10-羟基-癸-2-烯酸（10-HDA）、10-羟基-癸酸（10-HDAA）和对羟基苯甲酸甲酯（HOB），发现水平相似。然而，有证据表明，可能有物种特异性的敏感性差异QMP化合物，因为AC工人有较高水平的卵巢激活比上午工人。使用触角电位图，我们发现了主要QMP化合物和三种单独化合物（9-HDA，10-HDAA和10-HDA）的混合物的物种特异性敏感性差异。正如预测的那样，在所有情况下，Am比Ac更敏感（响应高1.3至2.7倍）。也有种属差异，工人随从吸引三种化合物（9-HDA，HOB，和10-HDA）。在所有显着不同的情况下，上午工人的4.5至6.2倍更强烈地吸引比Ac工人。因此，AC工人QMP的反应不如AC工人，9-HDA和10-HDA一贯引起更强的触角和随从形成的反应。
In highly social bees, queen mandibular pheromone (QMP) is vital for colony life. Both Apis cerana (Ac) and Apis mellifera (Am) share an evolutionarily conserved set of QMP compounds: (E)-9-oxodec-2-enoic acid (9-ODA), (E)-9-hydroxydec-2-enoic acid (9-HDA), (E)-10-hydroxy-dec-2-enoic acid (10-HDA), 10-hydroxy-decanoic acid (10-HDAA), and methyl p–hydroxybenzoate (HOB) found at similar levels. However, evidence suggests there may be species-specific sensitivity differences to QMP compounds because Ac workers have higher levels of ovarian activation than Am workers. Using electroantennograms, we found species-specific sensitivity differences for a blend of the major QMP compounds and three individual compounds (9-HDA, 10-HDAA, and 10-HDA). As predicted, Am was more sensitive than Ac in all cases (1.3- to 2.7- fold higher responses). There were also species differences in worker retinue attraction to three compounds (9-HDA, HOB, and 10-HDA). In all significantly different cases, Am workers were 4.5- to 6.2-fold more strongly attracted than Ac workers were. Thus, Ac workers responded less strongly to QMP than Ac workers, and 9-HDA and 10-HDA consistently elicited stronger antennal and retinue formation responses.
