Abstract: A device for rearing and sorting insects comprises a shaft, storage compartments, each compartment with a first closable opening for insertion of a water tray to hold pupae, and a second opening into said shaft, the inserted water tray being enclosed in the respective compartment apart from those two openings. A conveyor belt is aligned with an exit from the shaft to catch insects emerging from the pupae via the shaft. A classifier classifies insects on the conveyor belt into at least two classes; and a sorter sorts the insects on the conveyor based on output of the classifier to provide a sorted group of one of the classes.

Abstract: Apparatus for rearing of aquatic insects, comprises one or more water trays filled with water and larvae being reared, a water inlet leading to the water surface and a water outlet leading from the water surface, the water inlet closed with an inlet valve and the water outlet closed with an outlet valve. The tray has a mesh, and the insects reared in water in the tray are above the mesh. The tray has a water cleaning configuration in which the inlet and outlet valves are open to flush clean water through the tray while the mesh holds the insects so that they do not get flushed out as the water is changed.
