The invention discloses a field stocking device of Arma chinensis, comprising: a lower frame having communicated upper and lower surfaces; an upper frame identical with the lower frame in shape, wherein the upper frame is connected with the lower frame through support posts, the upper frame and the lower frame are in mirror symmetry based on a horizontal plane passing by midpoints of the support posts; a gauze cover made of gauze, wherein the gauze cover matches with the shape formed by the upper frame and the lower frame; an egg-laying screen which is releasably connected to the lower surfaceof the upper frame inside the gauze cover and which isolates the inner space of the gauze cover, and the egg-laying screen is parallel to the horizontal plane. The problem is solved that larvae hatched from eggs laid by Arma chinensis reared via the prior art have a very high death rate after the release to the field.
