等位酶分析表明，新热带区兰花蜜蜂（Euglossini）传粉者是脆弱的，因为假定的高频率的二倍体男性，一个结果的性等位基因多样性的损失在小的hyperteran人口与单基因座互补的性别决定。我们的分析1010名男性从27个品种的euglossine蜜蜂抽样横跨新热带区在2-11个多态性微卫星位点显示，只有5个二倍体男性的总体频率为0.005（95%CI 0.002-0.010），错误通过遗传nondetection二倍体男性可能很小。与基于等位酶的研究相反，我们检测到非常弱或不显著的群体遗传结构，即使是相距>500 km的一对群体，也可能是二倍体雄性频率低的原因。以前基于等位酶的分析中的技术缺陷可能导致兰花蜜蜂中二倍体雄性产生的相当大的高估。其他因素可能有一个更直接的影响人口持久性比二倍体男性对这些重要的新热带区传粉者的遗传负荷。
Allozyme analyses have suggested that Neotropical orchid bee (Euglossini) pollinators are vulnerable because of putative high frequencies of diploid males, a result of loss of sex allele diversity in small hymenopteran populations with single locus complementary sex determination. Our analysis of 1010 males from 27 species of euglossine bees sampled across the Neotropics at 2–11 polymorphic microsatellite loci revealed only five diploid males at an overall frequency of 0.005 (95% CIs 0.002–0.010); errors through genetic nondetection of diploid males were likely small. In contrast to allozyme‐based studies, we detected very weak or insignificant population genetic structure, even for a pair of populations >500 km apart, possibly accounting for low diploid male frequencies. Technical flaws in previous allozyme‐based analyses have probably led to considerable overestimation of diploid male production in orchid bees. Other factors may have a more immediate impact on population persistence than the genetic load imposed by diploid males on these important Neotropical pollinators.
