Continuous sieving apparatuses for pupae separation

A system, comprising:

• a sieving container comprising:
• a sieve surface defining a set of openings to enable movement of pupae through the set of openings from an interior volume of the sieving container, individual openings of the set of openings defined by:
• a length dimension measured along a longitudinal axis of a respective opening;
• and
• a width dimension measured along a transverse axis of the respective opening, the width dimension corresponding to a cephalothorax width of a pupa, and the length dimension greater than the width dimension;
• a perimeter wall enclosing the sieve surface and defining the interior volume of the sieving container;
• a funnel positioned adjacent the sieve surface to receive liquid and pupae from an upper surface of the sieve surface;
• and
• a basin comprising an outer wall and a bottom that together define a basin volume with an opening opposite the bottom, the basin sized to receive the sieving container and to retain a liquid.

A non-transitory computer-readable storage device comprising computer-executable instructions that, when executed by a computer system, cause the computer system to:

• cause a liquid to flow into a basin, the basin containing a sieving container, the sieving container comprising aa sieving surface and (ii) a perimeter wall enclosing the sieving surface to define an interior volume of the sieving container, and wherein a plurality of elongated openings are defined in the sieve surface to enable movement of insect pupae through the plurality of elongated openings from the interior volume, a width dimension of at least one of the plurality of elongated openings corresponding to a cephalothorax width of a representative insect pupa;
• cause introduction of an aqueous solution comprising a population of pupae into the sieving container at or near a second edge of the sieve surface;
• and
• cause performance of a sieving action to separate the population of pupae into a first group of pupae and a second group of pupae.
