Abstract: Egg laying device for flies, the device comprising: —a fly cage (20) comprising a container (22) comprising: —a base wall (26) which defines a base surface (30) which is orientated towards the interior of the cage (20), and —a lateral wall (28) which surrounds the base surface (30) and which defines a lateral surface (33) which is orientated towards the interior of the cage, and —a laying nest (50) which is intended to receive eggs laid by flies (M) which are enclosed in the cage (20), in which device the base surface and/or the lateral surface has/have, over more than 90% of the area(s) thereof, a radius of curvature greater than 0.5 cm, wherein the base surface (30) extends in a plane in an uninterrupted manner as far as the junction zone with the lateral surface (33).

Abstract: Egg laying device for flies, the device comprising:—a fly cage (20) and—a laying nest (50) which is intended to receive the eggs laid by flies which are enclosed in the cage (20), in which device the cage (20) is passed through by at least one egg laying aperture (54) which opens towards the exterior of the cage via an external opening (56), and wherein the laying nest (50) is arranged outside the cage and defines an egg laying zone (52) which extends opposite the external opening (56).
