Cuticular chemical profiles of Euglossa cordata L. males were analyzed to test whether ecological predictors affect their composition and relative proportion. Males were collected in areas of Caatinga and Atlantic Forest from Brazil during two distinct seasonal periods. We found 48 compounds from the cuticular extracts of males, which consisted of hydrocarbons (71.39%), acetates (16.79%), esters (10.5%), alcohols and others (1.31%). We verified that when specimens were separated between biomes, they did not show a qualitative differentiation, but a small quantitative variation of compounds was found between some alkanes. We suggest that these results reflect stability of epicuticular compounds even under variable environmental conditions.
对蓝带无刺蜂雄性个体的表皮化学特征进行了分析，以测试生态预测因子是否会影响其组成和相对比例。在两个不同的季节期间，从巴西的卡廷加和大西洋森林地区采集了雄性个体。我们从雄性个体的表皮提取物中发现了48种化合物，其中包括碳氢化合物（71.39%）、醋酸酯（16.79%）、酯类（10.5%）、醇类和其他物质（1.31%）。我们证实，当样本按生物群落进行区分时，它们没有表现出定性差异，但在一些烷烃之间发现了化合物的少量定量变化。我们认为，这些结果反映了即使在可变的环境条件下，表皮化合物仍具有稳定性。
