  3. Do entrance reducers affect SHB invasion? Hood, M. 2004. Bee World 51-59. Ellis, J. et al. 2003. J. Econ. Entomol. 1647-1652.

  4. Timeline of Measurements Introduced entrance reducers in half of the colonies and removed all SHB in all colonies Made uniform packages Recorded # SHB, # frames adult bees, # frames brood & removed all SHB

  5. Colonies with entrance reducers 9 Italian colonies 9 Russian colonies

  6. Colonies with regular entrances 9 Italian colonies 8 Russian colonies

  7. Do entrance reducers affect SHB invasion? No overall effect, p=0.1596

  8. Do entrance reducers affect SHB invasion? p=0.5381 p=0.1994 p=0.1308 p=0.4435

  9. What about other colony factors? p=0.3847 p=0.5591

  10. Does honey bee stock affect SHB invasion? Overall effect, p=0.0176

  11. Does honey bee stock affect SHB invasion? p=0.0255 p=0.3204 p=0.0280 p=0.0207

  12. What about other colony factors? p=0.2708 p=0.9257

  13. Entrance reducers • Honey bee stock What do we know at this point?

  14. Continuing research
