What happened to the research with regard to metarhizium anisopliae and hirsustella thompsoni biological agents that were going to give beekeepers another IPM management tool to fight varroa. Were further studies done and were they a dead end?
"H. thompsonii was harmless to the honey bees and did not have any deleterious effects on the fecundity of the queens. Microbial control with fungal pathogens provided promising new avenues for control of V. destructor and could be a useful component of an integrated pest management program in honey bee industry. Additional studies toward the development of more efficient application technologies, on the effects of the fungi on non-target organisms, and on an improvement of fungal formulations, should provide useful insights in the further development of these pathogens as biological control agents."
