Abstract
Nutritional studies (House, 1954, a-d; House and Barlow, 1956) with the sarcophagid Pseudosarcophaga affinis (Fall.) have been in progress for a number of years at the Belleville laboratory. Recently a new technique was developed for the care of large numbers of small lots of P. affinis. This makes use of a convenient holder for larval rearing tubes; a cage assembly for rearing pupae and flies; and a rack to hold a large number of cages, each easily accessible and uniformly illuminated, in a minimum of space. When this equipment is used, the treatment of the insects is more uniform and less time-consuming than with the equipment previously used. The new technique and equipment are described in this paper.
