Design of a Maggot Breeding Bed

A structure for breeding maggots was designed based on the living habits and crawling behavior of the fly larvae.It consisted of 4major components:(1)the escape-preventing feature that had a dry and rough surface to deprive moisture and smoothness for maggots to crawl out of the confinement;(2)the movement-oriented feature that made two sides of the bed higher and brighter than the center to take advantage of the natural tendency of maggots seeking for darkness and moving downward to lure them to the bottom of the structure;(3)the drainage system that used a pipe installed in the center of the lowest point of the bed to connect to the vertical sewage drain as a trap and for maggots collection;(4)the collection barrel that had water drains and a row of wood planks on top for worker to walk on as well as providing shades to encourage maggots to crawl into the barrel for collection.
