Cut-away view of a concept pupa-larva separator for continuous mechanized operation. A continuous mixed stream of larvae and pupae flow into a rotating drum consisting of parallel tapered discs. The anticipated diameter of the drum is approximately 40 cm. Because of their greater effective size, pupae (circles) are captured in the slots whereas larvae (rectangles) flow through and are caught in a tray from which they can be returned to culture trays to complete development. As the drum rotates, the pupae move upward and beneath a spray bar dislodging them into a collection tray. The design could be modified for various-sized species by changing the disc taper and amount of the space between disks.
