Sieving apparatuses for pupae separation

1. An apparatus, comprising:

a frame;

a sieving container comprising a base and a perimeter wall encircling the base to form an interior volume of the sieving container, the perimeter wall fixedly coupled to the base, the base defining a set of openings enabling movement of insects through the set of openings from the interior volume of the sieving container;

a basin attached to the frame, the basin sized to receive the sieving container and to retain a liquid; and

an actuation system attached to the frame and the sieving container, the actuation system configured to move the sieving container,

wherein moving the sieving container separates a population of insects present in the interior volume based on cephalothorax width.

2. The apparatus of claim 1 , wherein individual openings of the set of openings are 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 representative cephalothorax width of a representative insect of the population of insects.

3. The apparatus of claim 2 , wherein the representative cephalothorax width is a narrowest expected cross-sectional cephalothorax width.

4. The apparatus of claim 1 , wherein the actuation system is further configured to move the sieving container by agitating, oscillating, and/or shaking the sieving container.

5. The apparatus of claim 1 , wherein the base comprises an adjustable sieve surface configured to slidably adjust a width dimension of the set of openings.

6. The apparatus of claim 5 , wherein the adjustable sieve surface comprises a first sieve surface and a second sieve surface slidably connected to each other.

7. A method, comprising:

adding a volume of liquid to a basin of a sieving apparatus, the basin attached to a frame of the sieving apparatus, the basin sized to receive a sieving container and to retain the volume of liquid; and

causing an actuation system of the sieving apparatus to move the sieving container into the volume of liquid, the actuation system attached to the frame and the sieving container, the sieving container comprising a base and a perimeter wall encircling the base to form an interior volume of the sieving container, the perimeter wall fixedly coupled to the base, the base defining a set of openings enabling movement of insects through the set of openings from the interior volume of the sieving container,

wherein moving the sieving container into the volume of liquid separates a population of insects present in the interior volume based on cephalothorax width.

8. The method of claim 7 , wherein individual openings of the set of openings are 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 representative cephalothorax width of a representative insect of the population of insects.

9. The method of claim 8 , wherein the representative cephalothorax width is a narrowest expected cross-sectional cephalothorax width.

10. The method of claim 7 , wherein causing the actuation system to move the sieving container comprises causing the actuation system to agitate, oscillate, and/or shake the sieving container.

11. The method of claim 7 , wherein the base comprises an adjustable sieve surface configured to slidably adjust a width dimension of the set of openings.

12. The method of claim 11 , wherein the adjustable sieve surface comprises a first sieve surface and a second sieve surface slidably connected to each other.

13. The method of claim 7 , wherein moving the sieving container separates the population of insects into a first set of insects that remain within the interior volume and a second set of insects that pass through the set of openings.

14. The method of claim 13 , wherein the first set of insects are substantially female insects and the second set of insects are substantially male insects.

15. A system, comprising:

a frame;

a sieving container comprising a base and a perimeter wall encircling the base to form an interior volume of the sieving container, the perimeter wall fixedly coupled to the base, the base defining a set of openings enabling movement of insects through the set of openings from the interior volume of the sieving container;

a basin attached to the frame, the basin sized to receive the sieving container and to retain a liquid; and

an actuation system attached to the frame and the sieving container, the actuation system configured to move the sieving container,

wherein moving the sieving container separates a population of insects present in the interior volume based on cephalothorax width.

16. The system of claim 15 , wherein individual openings of the set of openings are 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 representative cephalothorax width of a representative insect of the population of insects.

17. The system of claim 16 , wherein the representative cephalothorax width is a narrowest expected cross-sectional cephalothorax width.

18. The system of claim 15 , wherein the actuation system is further configured to move the sieving container by agitating, oscillating, and/or shaking the sieving container.

19. The system of claim 15 , wherein the base comprises an adjustable sieve surface configured to slidably adjust a width dimension of the set of openings.

20. The system of claim 19 , wherein the adjustable sieve surface comprises a first sieve surface and a second sieve surface slidably connected to each other.
