(Adult) Nosema Apis and Nosema Ceranae
Nosema inhibits the bee’s stomach and digestive system. It spreads through a colony through regurgitation which occurs when bees process honey. When honey is made, a bee regurgitates it into another bee’s mouth, she regurgitates it into another’s, and that cycle repeats many, many times. Nosema often grows during late winter (also in fall and winter) when bees cannot defecate outside of the hive.
Symptoms: Many nosema-infected bees crawl on the ground, and developed unhooked (disjointed wings). Another symptom is fecal staining on the colony. This occurs when bees are coming out of the colony after winter to defecate, and instantly do so when exiting the hive. These symptoms are very similar to other diseases and parasites.

Firstly, foulbrood diseases only affect apis mellifera, and both diseases are a worldwide problem. European foulbrood is not as serious as …show more content…
Native to Asia, they have spread throughout the world since the 1950s, and now are wherever bees are too. Varroa mites completely rely on bees, and do so horribly. When a mother enters a hive, they enter a brood cell before capping, and burrow into the developing pupa’s exoskeleton. She then proceeds to lay eggs, and drink the bee’s blood. The mite weakens the bee just barely so the bee can escape the brood cell. The mites and mother then spread to other brood cells, and the bee dies from infection carried by the mites, often deformed wing virus. This cycle repeats and takes about 10 days, and can collapse an entire colony in just a few
