ABSTRACT An insect trap which attracts flying insects by use of light radiation in the visible and adjacent spectral regions and may also use attractant substance is described.The trap makes use of a linear flow of air blown from a venturi fan which encounters an airfoil shape. The airfoil increases the velocity of the airflow producing a negative pressure and directs the air and insects attracted by the trap into a porous container. The negative pressure and high velocity airflow causes even fast flying insects to be swept into the container. The airflow through the trap is affected very little by movement of air in the environment and thus accurate quantities of volatile chemical attract ants such as pheromones can be dispensed to enhance the attraction of the trap.
