METHOD OF REARING LARVA OF BEETLES AND REARING APPARATUS THEREFOR

PROBLEM TO BE SOLVED: To provide a method for the easy rearing of beetles achieving high survival ratio to imago in a high efficiency by the spontaneous transfer of the larva to a new feed bed and provide a rearing apparatus therefor. SOLUTION: A larva W of a beetle hatched from an egg is put into a new feed bed A in a rearing vessel 1. When the feed bed A is degraded by rearing, another new feed bed B placed in another rearing vessel 2 is connected to the old bed in a state in contact with each other. The larva W moves by its own powder from the old bed to the new bed searching for a fresh feed bed to achieve the spontaneous transfer of the larva to the new rearing vessel 2. The transfer procedure is repeated until the larva is grown to an imago. An opening of the rearing vessel 1 provided with openings 4, 5 at both ends is connected through a connecting means 3 to an opening of the rearing vessel 2 having openings 6, 7 at both ends.
