    1. 1. Examining Combs- What Do They Tell You? Clarence H. Collison EntomologistMississippi State University
    2. 2. Why Ever Look In The Brood Chamber(s)?Are You One Of Those People Who Never Go Below TheQueen Excluder; Never Look At The Brood Nest; Assume Everything Is Well??
    3. 3. Managing The Brood Nest Is Important
    4. 4. The Brood NestWhere the first signs of trouble inthe hive can most often be found! If you know your brood stuff!
    5. 5. Combs Are The Basic Structural Unit Of The Hive
    6. 6. Functions Of The Comb Reproduction Of The Colony Storage Of Nectar And Pollen Foundation For Establishing The Winter Cluster Orientation Point For Communicative Dances
    7. 7. Adequate Supplies of DrawnComb Is A Limiting Factor InMost Beekeeping Operations
    8. 8. Proper Arrangement Of Combs Bee Space 1/4- 3/8 Inches Burr Comb
    9. 9. Damaged Combs Loss Of Brood Area Increase In Drone Brood Increased Difficulty In Uncapping Honey
    10. 10. Why Examine Brood Patterns? Overall Condition Of The Colony Presence Or Absence Of A Queen Quality Of A Queen Availability of Fresh Nectar And Food Stores Checking For Bee Diseases/Varroa Mites Colony Strength Inclination To Swarm Population Balance
    11. 11. QUEENLESSNESS!• How to Recognize it? – First, Look for Lack of Eggs and/or Young Brood! – Look for signs of laying workers! – Look for virgin Queen! – Listen to the sound of the bees! – Look at Pollen! • Is there fresh pollen in the combs? • Is the pollen old and has a glossy appearance?
    12. 12. Quality Of The Queen Cannot Determine By Queen’s Appearance Examine The Brood Pattern Solid Brood Pattern Spotty Brood Pattern
    13. 13. Drone Layer
    14. 14. Laying Workers
    15. 15. Combs Can Serve As A Disease Reservoir Cappings Color Changes In Larvae/Pupae Scale Mummies
    16. 16. American Foulbrood Scales
    17. 17. Check ForVarroa Mites
    18. 18. Larvae of some sort crawling over the Comb!!!
    19. 19. Silk Webs in Tunnels in Combs!!!
    20. 20. What’s Wrong with these Bees??
    21. 21. When AdditionalHoney Supers Are Needed
    22. 22. Population Balance
    23. 23. Amount Of BroodWhat Is Normal?Can There Be Too Much?Can There Be Too Little?
    24. 24. Egg Larva Pupa TotalQueen 3 5½ 7½ 16Worker 3 6 12 21Drone 3 6½ 14 ½ 24
    25. 25. Worker DevelopmentEggsLarvae 2xPupae 4x
    26. 26. How Can You Tell IfThe Brood Cycle Has Been Broken?
    27. 27. Once A Queen Has Laid For 3Weeks Uninterrupted, The Healthy Hive Should Have: Brood Of All Stages/Ages 12-15% Eggs 30-35 % Uncapped (Larvae) 50-60% Capped (Pupae)Any Deviation From This Indicates A Break In The Brood Cycle/Pattern
    28. 28. What Causes A Disruption Of The Brood Cycle?Anything That Causes TheQueen To Stop Laying OrThat Destroys The Brood
    29. 29. Break In Brood Rearing Cycle PesticideKill Or Sudden Die-Off Of Adult Workers Death Of A Queen Lack Of Nectar Flow Or Food Stores Diseases And Parasitic Mites Weather
    30. 30. What’s Wrong Here??
    31. 31. Hatched Queen CellScattered Pollen In Cells What Might This Situation Indicate?
    32. 32. EmergencySupersedureSwarming
    33. 33. What Should You DoUpon Finding A Large Drone Population?
    34. 34. Prosperity! Doom!
    35. 35. How Many Pounds Of Honey?
