Abstract
A sieving device is described. The sieving device includes an adjustable sieve surface that includes a first sieve surface and a second sieve surface. Openings are formed in each of the first sieve surface and the second sieve surface so as to define a shared pathways extending through the adjustable sieve surface. The shared pathways are defined by a length dimension that is greater than a width dimension. The width dimension can correspond to a cephalothorax width of an insect.

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 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, and the mixed population of mosquito pupae comprising male mosquito pupae and female mosquito pupae;
- 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.
A method of sorting mosquito pupae, comprising:
- pouring a mixed population of mosquito pupae into a sieving container comprising a base and a perimeter wall encircling the base to define an interior volume, the base defining a set of openings enabling movement of mosquito pupae from the interior volume to outside the interior volume, and the mixed population of mosquito pupae comprising male mosquito pupae and female mosquito pupae;
- collecting a first portion of the male mosquito pupae that move from the interior volume to outside the interior volume;
- and
- collecting a second portion of the female mosquito pupae that are prevented from moving from the interior volume to outside the interior volume.
A method of sorting mosquito pupae, comprising:
- placing a population of mosquito pupae comprising male mosquito pupae and female mosquito pupae into a sieving container comprising a base and a perimeter wall encircling the base to define an interior volume, the base defining a set of openings enabling movement of mosquito pupae from the interior volume to outside the interior volume;
- causing a portion of the male mosquito pupae to move from the interior volume to outside the interior volume;
- and
- after causing the portion of the male mosquito pupae to move from the interior volume, collecting the portion of the male mosquito pupae.
