During the course of an investigation on the toxicity and repellency of various organic compounds to arthropods affecting man, studies were made on methods of propagating chiggers in the laboratory for test and taxonomic purposes. A brief discussion of the technique found most successful follows. A satisfactory culture medium for most of the species of chiggers studied consisted of soil and chicken manure from the floor of a chicken house. The soil was rendered free of animal life by heating it in a dry oven. There was some clay in the soil, and when wet samples were heated there was a tendency for many small pellets to form which allowed interspaces in the cultures, thus permitting the mites to adjust themselves more readily to the proper condition of moisture. It was later found that the medium could be duplicated by mixing one part chicken manure with five parts of soil from other sources.
