Fig 1. Prototype of Apiarium.

Each Apiarium included one small 125 mL (bottom part) and one large 1000 mL (top part) disposable plastic container. Four small tabs were cut on the bottom of 125 mL container to adhere a plastic mesh screen (#7). On the bottom of the 1000 mL container, a 5 cm slit was cut to insert a strip covered with chemicals. Holes were made on the body of both containers for air ventilation. Two sugar cubes (bee food) were secured on either side of the slit using hot glue. To set up the Apiarium, the lid on the 125 mL container was attached, and the 1000 mL container was placed on top of the 125 mL container. The Apiarium’s final volume was 800 mL.
