Pathogenicity of blastospores and conidia of Paecilomyces fumosoroseus against larvae of the mexican bean beetle, Epilachna varivestis mulsant. Southwestern Entomologist. 31(4):289-295. Interpretive Summary: Pest management requires continual searches for new control tactics to combat the development of pesticide resistance and reduce chemical pesticide load in crop production environments. Many fungi are known to provide effective biological contol of insect pests. However, the specific pest control combinations must be tested to demonstrate the potential for particular fungal agents to infect specific target insect pests. In this case, the fungus known as Pfr (Paecilomyces fumosoroseus) was tested for activity against the Mexican bean beetle, an important pest of beans and soybeans throughout much of North America. Two fungal spore types produced by alternative methods both caused infection and death of the target insects. This report opens the door for further research by government and industry scientists to determine the potential for development of this fungus as a biological pesticide.
