Charles F. Reichelderfer, 53, an entomologist at the University of Maryland, College Park, died August 24 in Adelaide, Australia, of injuries resulting from being struck by a car. He was in Adelaide attending the international meeting of the Society for Invertebrate Pathology.
Reichelderfer was known for his research involving microbial diseases of insects. In recent years, he worked with scientists at the United States Department of Agriculture's Beltsville Agricultural Research Center isolating and identifying new strains of Bacillus thuringiensis. This research has resulted in the development of biological pesticides that control a wide variety of insects.
Reichelderfer held an M.S. in microbial genetics from the University of Washington and a Ph.D. in entomology from the University of California at Riverside. He joined the University of Maryland faculty in 1968.
