A method and system (1) for breeding insects, using a plurality of individual crates (9), wherein at least a portion of each crate is filled with a substrate, containing feed stock, and immature phases of insects. Also provided is a climate area (3) housing the crates (9) that has an aeration system. A conveyor system (21) is included in the system for retrieving crates (9) from the climate area (3) and for returning same thereto. An observation system (27) for obtaining observations, including data and measurements, and downstream thereof a feedstock supply station (31) are arranged along the conveyor system (21). The method includes steps of aerating the substrate and the immature phases of insects with the aeration system, when in the climate area (3)； periodically retrieving at least one individual crate (9) of the plurality of crates by the conveyor system (21) from the climate area (3) and passing it to the observation system (27)； obtaining an observation of the substrate and the immature phases of insects in the at least one retrieved crate； and interpreting the observation of a retrieved individual crate and determining one of a requirement for adding an amount of supplementary feed stock, and a reason to withdraw the insects from further breeding for harvesting or discarding from further breeding.L'invention concerne un procédé et un système (1) pour élever des insectes à l'aide d'une pluralité de casiers individuels (9), au moins une partie de chaque casier étant remplie d'un substrat, contenant une matière première, et des phases immatures d'insectes. L'invention concerne également une zone de climat (3) recevant les casiers (9), qui comprend un système d'aération. Un système de transporteur (21) est inclus dans le système pour récupérer les casiers (9) de la zone de climat (3) et pour les renvoyer à celle-ci. Un système d'observation (27) pour obtenir des observations, comprenant des données et des mesures, et, en aval de celui-ci, une station de fourni
