Sacbrood is caused by a virus that is transferred from adult honey bees to young larvae. Larvae are most susceptible at 2 days old and are infected through the glandular secretions of infected nurse bees.
What is sacbrood disease?
Sacbrood is an infectious disease that affects the brood of honey bees. It occurs mostly as a mild infection, which only kills a few larvae, but it can be more severe. Few hives die out as a direct result of sacbrood but many are weakened to an extent where they succumb to other threats.

Is EFB contagious?
EFB is highly contagious and can remain viable for several years in honey, wax and equipment. Hives can often be infected with EFB but show no visible signs, however, sudden outbreaks of EFB can occur when the honey bee colony is under stress.
What causes chronic bee paralysis virus?
The infection may spread between hives as a result of indirect contact or direct contact between honey bees. Research shows that mainly adult honey bees can be infected with chronic bee paralysis virus by a topical contact with infected feces or by ingestion of virion-containing substances.
Why does a hive need queen?
HONEY BEE QUEEN’S ROLE IN THE COLONY The Queen Bee plays a vital role in the hive because she is the only female with fully developed ovaries. The queen’s two primary purposes are to produce chemical scents that help regulate the unity of the colony and to lay lots of eggs.
How is a queen bee born?
The life cycle of all insects, including honey bees, begins with eggs. During the winter season, a queen forms a new colony by laying eggs within each cell inside a honeycomb. Fertilized eggs will hatch into female worker bees, while unfertilized eggs will become drones or honey bee males.
