Abstract
A sieving apparatus for separating insect pupa is described. In an example, the sieving apparatus includes a sieving device attached to an actuation system. The sieving device includes a set of openings sized to correspond to a cross-sectional cephalothorax width of a representative pupa of a population of insect pupae to be separated. The actuation system is configured to move the sieving device in a manner that causes smaller insect pupae to pass through the set of openings. Larger insect pupae remain within the sieving device. Such movement can include moving the sieving device with respect to a liquid held in a basin of the sieving apparatus.
