| ABSTRACT: Bees are very important insects for agriculture, fulfilling an important role in pollination and renewal of the ecosystem. However, in several countries significant losses of colonies and population decline of honeybees and native bees have been reported in recent years. Most researchers reported that premature losses are linked to several factors, including viruses that have a great impact on the colonies. This article reports the identification of new viruses, some transmission routes, the association of these parasites with the symptoms of the diseases that affect the health of honeybees, as well as viruses that have been described in Brazil. |
