: The objectives of this study were to identify the genetic effects involved in the expression of individual honeybee grooming behavior in response to and to determine if there is an association between the expression of this behavior and the infestation levels of Varroa in the honeybee colonies. : The study was conducted in a population of 112 colonies composed of six segregating genetic groups that were derived from two honeybee lines that were selected for high and low individual honeybee grooming behavior. The individual honeybee grooming behavior of 3974 workers from the 112 colonies was measured by the time it takes a bee to respond in performing grooming behavior after a mite was placed on her body. The population growth of Varroa in the colonies was measured over a period of six months. : Differences between the genetic groups were found in the expression of individual honeybee grooming behavior ( < 0.01). The distribution of means of the genetic groups fits a genetic additive and dominance effects model for the expression of individual honeybee grooming behavior ( = 0.95; < 0.01). Differences between the genetic groups were found in the colony population growth of Varroa over a period of six months ( < 0.01). A positive correlation was found between the mean individual honeybee grooming behavior of the colonies and the Varroa level of infestation in the colonies ( = 0.57; < 0.01). : The results indicate that additive and dominance genetic effects are associated with honeybee individual grooming behavior and that this trait has an effect on the levels of Varroa infestation in the colonies.
本研究的目的是确定参与单个蜜蜂梳理行为表达以应对[具体刺激未提及]的遗传效应，并确定这种行为的表达与蜜蜂蜂群中瓦螨的侵染水平之间是否存在关联。：该研究在由六个分离遗传群体组成的112个蜂群群体中进行，这些群体源自两个因蜜蜂个体梳理行为高和低而被选择的蜜蜂品系。对112个蜂群中3974只工蜂的个体蜜蜂梳理行为的测量方法是，在一只螨虫放在蜜蜂身上后，测量蜜蜂做出梳理行为反应所需的时间。在六个月的时间里测量蜂群中瓦螨的种群增长情况。：在单个蜜蜂梳理行为的表达上发现了遗传群体之间的差异（<0.01）。遗传群体均值的分布符合单个蜜蜂梳理行为表达的遗传加性和显性效应模型（=0.95；<0.01）。在六个月的时间里，发现遗传群体在蜂群中瓦螨的种群增长方面存在差异（<0.01）。发现蜂群中蜜蜂个体梳理行为的均值与蜂群中瓦螨的侵染水平之间存在正相关（=0.57；<0.01）。：结果表明，加性和显性遗传效应与蜜蜂个体梳理行为相关，并且该性状对蜂群中瓦螨的侵染水平有影响。
