The present invention relates to devices and methods for separation of non-adult insects, such as pupae or larvae, according to sexual dimorphisms or developmental stages that can affect their size.

The present invention relates to devices and methods for separation of non-adult insects, such as pupae or larvae, according to sexual dimorphisms or developmental stages that can affect their size.

Methods and systems are provided to insect harvesting. The system may include a tank for holding or growing live insects or both. The tank has an opening on a side portion of the tank, and the opening is positioned higher than a bottom portion of the tank. A negative stimulus device for repelling live insects toward a first direction or point towards the opening on the side portion of the tank is provided. A positive stimulus device is provided, situated at the opening of the tank. A product box for receiving live insects has an opening for receiving the live insects. A slide is coupled with the opening of the product box. In an operative position, the tank is positioned such that the live insects leaving the opening of the tank move down the slide to the opening of the product box.

The invention relates to a method of sorting insects comprising the successive steps of: providing (S1) a mixture comprising nymphs, and sieving (S3) enabling separation of the nymphs from the rest of the mixture comprising sieving said mixture with a sieve having a screen of plastic material (S4).

This method may be complemented by densimetric sorting.

The invention also relates to a corresponding insect sorting device.
