We have the 400 power microscope but have never known how to prepare a slide
for checking for Nosema and what to look for. We would really appreciate it
if you could you give me a "microscope for dummies" version of how to
prepare a slide and what to look for etc or refer me to somewhere that would
provide this.
This rough and ready method will bring down a horde of sneerful, scornful
mails from the posh folks who do it the proper way. As you're Commonwealth I can
use terms with which our host might not be too familiar.
Invert a teacup. Into the concave base crush with a teaspoon the abdomens of
a few bees from a known hive. Add a few drops of distilled water (ice
scrapings from the freezer wall allowed to melt). Stir. Transfer a drop of the
fluid to the slide. Add a cover slip. Place on the microscope stage. Focus.
Look at the fluid. You will see all sorts of floating gubbins: vacuum cleaner
hoses; leafless fir trees; silver balloons; rounded geometrical shapes of
varying complexity and size; grains of rice. These are tracheae; plumose hairs;
air bubbles; pollen grains; nosema spores, in that order.
I hope that helps.
Chris
