蜜蜂健康主要受破坏蚁、病毒、小孢子虫、农药残留和营养不良的影响。这些因素之间的相互作用可能是近年来世界范围内报道的蜂群损失的原因。本研究以以色列急性麻痹病毒（IAPV）为研究对象，利用喙延伸反应（PER）技术和射频识别（RFID）技术研究了该病毒对欧洲蜜蜂（Apis mellifera L.）觅食行为和归巢能力的影响。采集花粉的蜜蜂来源于未检测到蜜蜂病毒水平的蜂群，人工接种IAPV诱导病毒感染。结果表明，接种iapv的蜜蜂对低蔗糖溶液的反应比未感染的蜜蜂更敏感。感染两天后，在这些蜜蜂的头部检测到大约107个IAPV拷贝。与未感染iapv的觅食蜂相比，感染iapv的觅食蜂的寻巢能力明显下降。这些数据提供了证据，证明IAPV在蜜蜂头部的感染可能使病毒扰乱蜜蜂的觅食功能，并干扰蜜蜂负责学习、导航和定向的大脑功能，从而使蜜蜂对蔗糖的反应阈值降低，迷失了返回蜂巢的路。
Honey bee health is mainly affected by Varroa destructor, viruses, Nosema spp., pesticide residues and poor nutrition. Interactions between these proposed factors may be responsible for the colony losses reported worldwide in recent years. In the present study, the effects of a honey bee virus, Israeli acute paralysis virus (IAPV), on the foraging behaviors and homing ability of European honey bees (Apis mellifera L.) were investigated based on proboscis extension response (PER) assays and radio frequency identification (RFID) systems. The pollen forager honey bees originated from colonies that had no detectable level of honey bee viruses and were manually inoculated with IAPV to induce the viral infection. The results showed that IAPV-inoculated honey bees were more responsive to low sucrose solutions compared to that of non-infected foragers. After two days of infection, around 107 copies of IAPV were detected in the heads of these honey bees. The homing ability of IAPV-infected foragers was depressed significantly in comparison to the homing ability of uninfected foragers. The data provided evidence that IAPV infection in the heads may enable the virus to disorder foraging roles of honey bees and to interfere with brain functions that are responsible for learning, navigation, and orientation in the honey bees, thus, making honey bees have a lower response threshold to sucrose and lose their way back to the hive.
