The utility model relates to the technical field of
trapping, in particular to a
bark beetle trapper which comprises a
trapping barrel and a suction
assembly, a
trapping opening is formed in the surface of the upper end of the trapping
barrel, a supporting rod is installed in the trapping opening, and the suction

insect collecting net bag is installed in the lower end of the suction cup in a clamped mode, the bottom cover is installed on the outer portion of the lower end of the suction cup in a threaded mode, and the fan is installed at the bottom end in the bottom cover. The
bark beetle trapping device has the advantages that the fan rotates on the bottom cover to enable suction
airflow to be generated in the trapping barrel and the suction disc, an attractant can be assisted in sucking
bark beetles in the trapping barrel, the trapping effect of the bark beetles is improved, a drainage plate enables
bark beetle corpses to be sucked into the beetle collecting net bag to be collected, the beetle collecting net bag can be pulled out from the bottom of the suction disc to be cleaned, and the
bark beetle trapping device is convenient to use. The bottom cover is in threaded connection with the bottom of the suction cup.
