Following evaluation of methods that could be utilized in the dissemination of fungi pathogenic to the spotted alfalfa aphid, Therioaphis maculata (Buckton), a program was developed to produce Entomo phthora exitialis Hall & Dunn, E. virllenta H. &. D., and E. oronata (Cost.), on selected media in small sealed containers for shipment to counties within the State of California requesting fungi. During 1956, a total of 1,754 culture units were sent to nine counties in the San Joaquin and Sacramento valleys for placement in field plots.
