Lindgren Funnel Traps
Versatile and effective trapping system was developed by Staffan Lindgren at Simon Fraser University and is successful for monitoring or mass trapping of ambrosia and bark beetles in coniferous forests. Traps were designed to use semiochemicals to attract beetles, but they capture other tree pests as well when using various crushed grains as lures. (BioQuip does not supply pheromones or other lures; they must be purchased locally.)
Traps consist of a series of four, eight, or 12 plastic funnels arranged vertically. The conical shape of each funnel allows an unobstructed 360-degree catch radius. Funnel diameter is 8″ (20 cm). The downward angle of each funnel causes fast-approaching beetles to be deflected downward into the collecting cup. Escape is prevented by the baffling arrangement of funnels. Capture does not rely on sticky surfaces or chemical pesticides. Beetles are killed through heat and dehydration. A conical drain in the collection bottle increases drainage and prevents clogging from debris. A collecting cup without drain is available as a separate item for those using a liquid killing agent. The cups are 4″ in diameter and attach by twist lock.
Traps are hung from branches or from rope strung between trees. They are lightweight and collapsible for easy transport.
