a, In vitro rearing of honeybee larvae. b, Queen determination rates of in vitro rearing trials among different studies and diets. An additional increase of sugar content in the normal RJ diet (12% (w/w) glucose and fructose, each) slightly, but not significantly, increased queen rate (5.9%). Our queen rates are well in agreement with a median queen determination rate of 9.4% (0–28.3%) in all other published in vitro larvae rearing experiments using 50 to 66% RJ diets. Although there is considerable variance in the queen determination rate within and among different laboratories, bee genotypes and probably RJ sources, it has never, to our knowledge, approached 100%.
