In order to clarify the impact of temperature on the sealed broods development of honeybee,we placed worker s sealed brood of Apis cerana cerane Fabricius and Apis mellifera ligustica Spinola in incubators,which held constant different temperatures,and treated them at 24℃for certain hours.
The present researches concentrated on effect of temperature on the developmental period, abnormity and mortality rate,morphological parameters of the sealed broods.
