About 90% of the 300,000 honeybee colonies in this province of southern China are A. cerana.Generally this species is more successful here than A. mellifera, mainly because it makes better use of forage in areas where this is scattered, and is more able to survive dearth periods in the hot summer and autumn. A. cerana forages for 2 3 h longer each day than A. mellifera. In addition A. cerana flies faster, and fewer are caught by predatory wasps. It is also less susceptible to EFB and sacbrood, and to damage by wax moths. These and other factors are discussed. Techniques developed in the Province since 1957 have included: transferring A. cerana to modern hives, managing colonies to increase production, selection for high honey yields. recently, instrumental insemination of A. cerana has been successful, using a modified Laidlaw apparatus. Chinese queens introduced to Thailand in 1984 did not survive; more were sent in late 1985, and 2 survived.
