JIADUO INTELLECTURE INSECT MONITORING LAMP utilized the most insects like the blacklight, use the 20w blacklight or 200w writelight as light source, also use 5mm glass as insect crash screen; the light source open in special time to process lure insect, the electricity-road control the long red out to kill the pests. In order to guarantee the killing speed, hand in insect have 2proccesses, the small plate accto pass. When the insects fall into the small plate, through the small plate pass fall into the big plate then into the bag. The materials use the stainless steel, rainproof cap utilize the fly wire design, in order to lure insects easy fall into the collecting plate, the plate's angle is 15·.
