The tunnel grid for collecting bee venom is made up of a rectangular frame with two vertical sides on which some horizontal channels are made that a conducting wire goes through, which is mounted in the channels of some vertical spacer strips that are located on every side of the frame. A pair of longitudinal and lower sides are positioned in the middle of the distance between the vertical sides, thus completing and reinforcing the rectangular frame. A glass plate is clamped on each of the sides of the rectangular frame so that they create a tunnel inside which other glass plates are mounted, that are also inserted in some envelopes made out of plastic material glued onto a synthetic cloth support. The tunnel is partially covered at the top with a detachable bar (a perch) which is equipped with a battery-operated lamp. The interior face of the lower longitudinal sides is lined with a textile material, one of them having an entrance slot at its base, placed in between the coil of the conducting wire and the vertical sides, whilst there are also some straining wedges.
