Honey bees consider larval nutritional status rather than genetic relatedness when selecting larvae for emergency queen rearing

Abstract In honey bees and many other social insects, production of queens is a vital task, as colony fitness is dependent on queens. The factors considered by honey bee workers in selecting larvae to rear new queens during emergency queen rearing are poorly understood. Identifying these parameters...
