From Cantwell 1970, assuming that each sampled bee is diluted with 1 mL of water.
Average spore count per bee is then:
Average count per single small square x 4,000,000.
Total count per large square (16 small squares) x 250,000.
Or total count per 5 large squares (80 small squares) x 50,000.
Everything on this website is open access and freely given to beekeepers and researchers worldwide, on a not-for-profit basis. I gladly accept gifts of appreciation from my readers and supporters. You can donate via Paypal below. Notice: I will, for tax purposes, treat all Paypal donations as "gifted research grants" to be applied towards beekeeping research and the reporting on thereof -- given by you with "detached and disinterested generosity" out of "affection, respect, admiration, charity or like impulses." Since I am not a 501(c)(3), your gifts are not tax deductible.
Thank you!
Randy
ScientificBeekeeping is a not-for-profit enterprise, and I'm happy to receive notes of thanks for how information on this site has contributed to my readers' success at beekeeping (and sometimes saved them hundreds or thousands of dollars). It is your support that allows me to devote my life to this site. All donations go towards website maintenance, bee research costs (typically tens of thousands of dollars per year), re-donations to fund research by others, and a small amount to partially offset the incredible number of hours that I spend in research and writing. I guarantee that every penny is pinched and well spent!
I appreciate the notes of support that I receive from all over the world. Seeing who is donating, their locations, and the little notes that come with contributions help to let me know how I should direct my research and writing. In appreciation, and in order to show who is supporting my research and writing, I honor below those who have recently made substantial donations:
