How to control O.E.?
After years of experiments to try and control O.e., there has been only one method that works. If a gravid female is spore free and placed in a small netted enclosure with a few potted milkweed plants, she will lay eggs that are spore free. This new generation, and others, will be “clean” if they are not contaminated by mating with monarchs outside of the gene pool. The spores are easy to detect by rubbing their abdomen on a clear piece of tape, putting it on a 4X5 white card, and placing it under a microscope with 100 power with using light from a lamp shinning down from above. Images of O.e. spores may be seen at www.butterflyfunfacts.com/oe.php.
