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.
Claims19
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.
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 mixed population of mosquito pupae comprising male mosquito pupae and female mosquito pupae, the base defining a set of openings enabling movement of mosquito pupae from the interior volume to outside the interior volume, 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 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, 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;
- 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.
