Worker Bees
§ § § The life of a worker Gestation cycle – 21 bee days Diploid Cleaning Brood (day 1 – 3) Attending queens (~ day 7 – 12) Feeding Brood (~ day 4 – 12) Capping Cells Packing and Processing pollen Making wax and comb (~ day 18) Temperature regulation (~ day 12 – 18) Receiving and processing nectar (~ day 12 – 18) Guard Bee Duty (~ days 18 – 21) Field bees (foragers) (~days 22 – 45)
The drone endophallis Varroa
• • • The life of a drone Gestation – 24 days – HAPLOID Male Life span ~ 58 days PREFERED BY VARROA Confined to hive until ~ 12 days old Cant feed himself No purpose in the hive Sexually mature at ~ 2 weeks old Generally accepted in ANY hives Goes to Drone Congregation areas on warm afternoons • DCA – Queen Mating Areas • Mating lasts up to 5 seconds
the Queen
The life of the queen • • • Gestation – 16 days Remains in hive for ~ 7 days Several mating flights mate with between 10 and 25 drones Start laying eggs ~ 3 – 7 days after mating The only fertile female in the colony May live up to 5 years Lays between 1500 and 2000 eggs per day Will only leave the hive if swarming
Anatomy
Review • True insects • Honey Bee - Apis Mellifera • Three ‘types’ • queens and workers - female – diploid • drones – Haploid • Gestation • Worker – 21 days - ~ 45 life span • Drone – 24 days - ~ 58 day life span • Queen – 16 days - ~ 2 to 5 years • Varroa Mite - Prefers drone cells • Swarms are how the species propagates
• Review Glands • Hypopharyngeal • Royal Jelly production • Mandibular • Queen Mandibular Pheromone • Affects social behavior • Nasonov • ‘marking’ pheromone - Come Hither’ • citrus and/or geranium smell • Dufours • Koschevnikov • Alarm pheromone • ‘careful now…’
