狄斯瓦螨与一种或多种应激源（如食物供应不足或化学品暴露）的结合被认为是蜜蜂群体损失的主要原因之一。我们研究了花粉可用性对蛋白质含量和幼蜂体重的交互作用，这些幼蜂出现在有和没有V. destructor感染的情况下。随着花粉可用性的降低，以及营养蛋白质的一致性降低，我们预计在蛹期期间的狄斯韦托虫侵染将比没有侵染对蜜蜂发育产生更大的负面影响。此外，当在出苗后用充足的花粉饲养时，预计受侵染的蛹不能补偿由于V. destructor造成的早期损失。我们发现，无论是V. destructor感染和减少花粉可用性降低体重，腹部蛋白质水平，并增加头腹蛋白质的比例。花粉的可用性确实没有导致补偿在成年后1周的幼蜂中由V.destructor侵染引起的质量和蛋白质含量的降低。V. destructor和营养都是研究蜜蜂健康的人最关心的问题，这项研究表明，两者都对幼蜂有重大影响，而且充足的花粉不能弥补V. destructor寄生引起的质量和蛋白质含量的减少。(c)2013爱思唯尔有限公司保留所有权利。
Varroa destructor in combination with one or more stressors, such as low food availability or chemical exposure, is considered to be one of the main causes for honey bee colony losses. We examined the interactive effect of pollen availability on the protein content and body weight of young bees that emerged with and without V. destructor infestation. With reduced pollen availability, and the coherent reduced nutritional protein, we expected that V. destructor infestation during the pupal stage would have a larger negative effect on bee development than without infestation. Moreover, when raised with ample pollen available after emergence, infested pupae were expected not to be able to compensate for early losses due to V. destructor. We found that both V. destructor infestation and reduced pollen availability reduced body weight, abdominal protein level, and increased the head to abdomen protein ratio. The availability of pollen did indeed not result in compensation for reduced mass and protein content caused by V. destructor infestation in young bees after 1 week of their adult life. Both V. destructor and nutrition are top concerns for those studying honey bee health and this study demonstrates that both have substantial effects on young bees and that ample available pollen cannot compensate for reduced mass and protein content caused by V. destructor parasitism.
