Abstract
Method and apparatus for rearing insects is disclosed. Information concerning the physical and dietary needs of the insect as well as behavioral characteristics are utilized to maximize the number of larvae reared per unit surface area of diet and per unit of rearing area while minimizing the amount of labor and materials required. An enclosed rearing unit is provided which can be located within an appropriate environment for rearing the insects. There are three sections within the rearing unit: 1) a diet space, 2) a larval space, and 3) a frass space. The diet space includes an appropriate diet medium for the insects. The larval space is located below the diet space and includes a series of vertical partitions perpendicular to and in contact with or nearly in contact with the diet medium such that the insect larvae are able to disperse themselves over the partitions. The frass space is located below the larval space such that any frass collects within the frass space as it is produced and does not interfere with the larval space or the diet space. The rearing system can further include an emergence pan including an outlet for allowing emerging adults to enter an oviposition cage. …
