ABSTRACT. Microbial control of insects is based on the rational use of pathogens to maintain environmentally balanced pest population levels, and Metarhizium anisopliae has been the most studied and most utilized fungal species for that purpose. The natural genetic variability of entomopathogenic fungi is considered one of the principal advantages of microbial insect control. The Molten Salt Reactor. In the early 60s Weinberg made a significant discovery. Instead of solid Uranium fuel rods causing a chain reaction in a pressurized containment vessel, he achieved the same chain reaction with the Thorium fuel suspended in a salt solution.
