Beetle sensing device and method of use

An improved beam-interruption type pest detection sensor assembly suitable for use with known pest traps in which pests are deflected downward and fall by gravity comprising in cooperative combination:

• a) a mesh screen assembly comprising;
• a funnel having a wider diameter first end connectable to the output end of a pest trap, a narrower second end adaptable to connecting to a sensor assembly, and having a fixedly mounted mesh screen therein and mountable on;
• b) a sensor assembly comprising;
• a focused reflective concave mirror sensor fixedly mounted within a co-operatively dimensioned sensor container, said focused reflective concave mirror sensor comprising a mounting plate, a concave mirror forming cradle having a concave mirror and a reflective sensor wherein said concave mirror having a focal length f=R/2, the spacing between said reflective sensor and said focused reflective concave mirror is equal to the radius R of said mirror producing an image having equal size and opposite orientation on said reflective sensor;
• and
• c) a catch can assembly comprising;
• a co-operatively dimensioned trapping container having a first end mountable to the exit of said sensor assembly, a second end sealed thereby forming a collection container;
• thereby creating a beam-interruption pest sensor using focused reflective concave mirror sensor having improved sensitivity, improved sensing consistency, reduced clogging risk, reduced energy consumption, and adaptable to mounting on pest traps in which pests are deflected downward and then fall by gravity.
