Asian Bees (A. cerana) Apis cerana is the sister species of our bees (A. mellifera). It is the original host of the varroa mites (Varroa jacobsoni, Varroa destructor). Bees are generally smaller and with more striking bands on the abdomen compared to our bees. Most photoes taken in China, some in Thailand. |

From Album: Asian Bees (A. cerana) A bee resting by biting on the anther of Pichira macrocarpa (Bombacaceae). Both dorsata and cerana forage on this plant by hovering and collect pollen. Hoving must be very tiring because you bees taking rests on leaves. This bee becomes smart and is taking a rest on the job. Xishuangbanna, Yunnan, China. April 2002. |

From Album: Asian Bees (A. cerana) A cerana foraging on flowers on a Chinese Tangerine (Citrus spp, Rutaceae). I was very lucky to see bees foraging on this tree. All the normal trees had finished flowering by May last year. But my uncle had moved this tree to the front of his house, delaying the flowering by about 2 weeks and also enabling me to see bees foraging that day! May 4, 2002. Shaoshan, Hunan, China (Zach's home town). |

From Album: Giant Bees (A. dorsata) A giant honey bee foraging for water on a wet stone. This is the first time I saw dorsata foraging for water. A cerana worker was seeing foraging for water around the same area. I did not wante to use the flash in case the flash scares her away, so this picture is rather dark. |

From Album: Asian Bees Apis cerana larvae, about 2 days before being sealed. Unless you start with brand new foundation for Apis mellifera, you do not see beeswax this white for brood cells. In Apis cerana, they do not seem to recycle the wax for brood cells as much as our bees. |

From Album: Asian Bees Apis cerana workers on capped brood. A. cerana probably never reuses old wax for brood capping (as the mellifera do), since the brood capping is almost as clean as the honey capping. |

From Album: Asian Bees Apis cerana workers on pollen cells. Pollen cells are never sealed and are never filled near the top -- bees always leave about 20% space. Not sure why. Matching Comments: I mean Apis cerana |

From Album: Asian Bees Strange drone caps of Apis cerana. Workers remove the wax a few days after the drone larvae were sealed, exposing the cocoon-cap which has a small hole on it. The signicance of the hole is not clear. However, we do know the strong capping can only be opened by the drone when he emerges. Workers outside cannot open the caps, leaving dead drones to mummify inside. This can be another mechanism of mite-resistance because if the drone pupae has too many mites and dies, mites will be trapped inside and will also die. |

From Album: Dwarf Bees An Apis florea worker foraging on a mimosa (Fabaceae), which was planted in a vegetable garden near Jinghong. Again, we found florea, cerana, and dorsata all foraging on this plant at the same time (around noon, April 2002). |

From Album: Dwarf Bees Three dwarf honey bees (Apis florea) foraging on asters in a Thai flower market. After a bunch of bee scientisits discussing the nest should not be far, we found a nest on a tree above the roof not far away. I also saw Apis cerana foraging on cabbage flowers but did not get a good shot. We failed to see any dorsata foraging in the market, but did see stingless bees also. Chiangmai, Thailand. March 23, 2000. |

From Album: Dwarf Bees A closeup of florea workers on the top flat surface. This is also called the "dance floor" because florea workers dance on a flat surface, they do not use gravity as a reference as Apis mellifera and cerana, which both live side dark cavities. |

From Album: Honey for Sale A lady selling honey harvested from Apis cerana. The price is about 5 yuan per half kilo ($0.60 per lb). The honey is usually robbed from unmanaged colonies. I have also seen honey and brood sold from dorsata colonies. Xishuangbanna, Yunnan, China. April 8, 2002. |

From Album: Apiary Scenes Apis cerana kept in fixed wooden boxes. These were then left in the balcony of a government office building and apartment. In the far background you can see a similar hive on a stand. Out of the 2 million colonies of Apis cerana in China, some are still kept this way, in hives with non-movable frames. Yunnan, China. May, 2001. |

From Album: Apiary Scenes Front yard beekeeping of Apis cerana colonies. This is at Puwa, a place about 100 km from Beijing. With very tough terrain, it took us about 4 hours to travel there from Beijing. We were there to look for varroa mites (nothing) and to buy two colonies for research. May 12, 2001. |

From Album: The Academics. Prof. Zachary Huang measuring brood cell volume of the Asian hive bee (Apis cerana) using a syringe. Zachary obtained his Ph.D. (1988) with Dr. Gard Otis at University of Guelph, Canada. Zachary works on honey bee and varroa mite biology. His best known work is the "social inhibition" model for explaining how workers inside a colony "know" when to become foragers. With his collaborators, he was the first one successfully to accomplish the following in acarines (mites): characterization of neurotransmitter receptors (1990) and cloning and sequencing of a sodium channel gene (2002) .

If you want to learn more about the Asian hive bees (Apis cerana), read his book (Beekeeping for honey production in Sri Lanka: Management of asiatic hive honeybee Apis cerana in its natural tropical monsoonal environment, ISBN 955-9282-01-8, pp 232, Printed by Sarvodaya Vishva Kekha, Tamalana, Sri Lanka). He is now a senior lecturer at University of Ruhuna, Sri Lanka. Baton Rouge, May 19, 1999. |

From Album: Varroa mites All these six mites did not reproduce and all had defecated on the Apis cerana workers. This is also true in Apis mellifera: if a mite has defecated on the pupae, she would have no daughters. If she has daughter mites, she would be defecating on the wall. |

From Album: Brood patterns Brood of Apis mellifera uncapped by workers. Pupae seem to develop normally within these uncapped cells. The significance of this is not clear. Some think bees maybe uncapping the cells when they detect varroa mites there. It is true also in Apis cerana this phenomenon is more common, where varroa is not a problem. MSU apiary.
