To analyze the specialization on tasks by a honeybee workers from both genetic and behavioral backgrounds of the bee are determined. Our hypothesis is if genetic background takes part in the specialization, all workers in particular task should be in one patriline group and if behavioral background does, they show similar ethograms or behavioral patterns.As a specialist task we observed "undertaking" behavior. Because of the sample size was too small and kin-analysis using DNA-markers was not so clear, we could not unveil the contribution of genetic background on the specialization. Whereas, there were significant differences of lineup of behavioral contents and performance frequency of each content between workers that took specialized task and ones took only general tasks. Also specialized workers showed hypersensitive response against exogenous stimuli.Only 1 % of worker bees showed specialization, so specialization is thought to be subjected genetic background, rather it suggests that a portion of workers from (several) kin group (s) has set lower threshold to response and they are the potential specialists.It is necessary to use methods with higher sensitivity on DNA markers, and for this purpose we have introduced sequence-gel electrophoresis. Further we need another specialized task which can be observed in ordinary s-zed colony because the observation hive base sampling can limited the size of specialist samples.

为了分析来自蜜蜂遗传和行为背景的蜜蜂工人对任务的专业化。我们的假设是，如果遗传背景参与了专业化，那么所有特定任务的工人都应在一个patriline组中，如果行为背景确实如此，它们会显示相似的伦理图或行为模式。作为我们观察到的“承担”行为的专业任务。由于样本量太小，使用DNA标记的亲属分析还不太清楚，因此我们无法揭示遗传背景对专业化的贡献。鉴于，行为内容的阵容和执行专业任务的工人之间的每个内容的阵容存在显着差异，并且仅执行了一般任务。另外，专业工人也表现出对外源刺激的高度反应。只有1％的工人蜜蜂表现出专业化，因此被认为是受到遗传背景的对象，而是表明，来自（几个）KIN组的一部分工人对响应的阈值设定了较低的阈值，它们是潜在的专家，它们是对较高的dna Markers of Dna Markers的潜在专家，并且对DNA Markers进行了较高的敏感性，并以此为目的。此外，我们还需要另一个专业任务，可以在普通的S Zed菌落中观察到，因为观察蜂箱基础采样可以限制专家样品的大小。
