1. A method of sorting mosquito pupae, comprising:
introducing a mixed population of mosquito pupae at a first side of a base of a sieving container, the mixed population of mosquito pupae comprising male mosquito pupae and female mosquito pupae, the sieving container comprising the base and a perimeter wall encircling the base, the base defining a set of openings enabling movement of mosquito pupae from the first side through the set of openings to a second side, each opening of the set of openings defined by:
a length dimension measured along a longitudinal axis of a respective opening, wherein a value of the length dimension is greater than an overall length of a representative mosquito pupa;
a width dimension measured along a transverse axis of the respective opening, wherein the width dimension is greater than a first cross-sectional cephalothorax width of a representative male mosquito pupa and less than a second cross-sectional cephalothorax width of a representative female mosquito pupa; and
a space dimension measured between longitudinal edges of two adjacent openings along the transverse axis, wherein a value of the space dimension corresponds to the first cross-sectional cephalothorax width of the representative male mosquito pupa;
collecting a first portion of the male mosquito pupae that pass through the set of openings from the first side to the second side; and
collecting a second portion of the female mosquito pupae that are prevented from passing through the set of openings from the first side to the second side.
