Effects of Three Types of Pollen on the Growth and Development of Honey Bee Larvae (Hymenoptera, Apidae)

Pollen serves as an essential protein source for honey bee larvae. The nutrients in pollen greatly influence larval growth and development. Here, the survival, prepupal weight, developmental stage, digestibility midgut cells ( Apis mellifera L.) larvae were evaluated by performing vitro 5-ethynyl-2′-deoxyuridine (EdU) assays on reared three single pollens Brassica napus L., Armeniaca sibirica Pyrus bretschneideri Rehd.) a mixture (mixture of equal proportions). results showed that survival rate fed 10 mg rape was lowest P < 0.05), but there no notable differences among groups receiving other types doses > 0.05). weight apricot significantly lower than those dramatically higher pear Pear mixed exerted negative effects nuclear area early stage In conclusion, detection using EdU assay might be effective method to assess nutritive value bees.
