A vacuum machine for capturing insects has a plenum having a collection opening at one end for collecting insects in an airflow, a fan assembly joined to the plenum at an opposite end from the opening at one end, the fan assembly having a motor-driven fan adapted to draw air through the opening for collecting insects, and an end opposite the end joined to the plenum, and a structure joined to the fan assembly at the end opposite the end joined to the plenum, the structure having elements adapted to kill insects drawn through the fan assembly and to collect the killed insects. The vacuum machine is adapted to be attached to and carried by a tractor with an adjustable elevator adapted to present the collection opening of the plenum oriented at different heights and directions toward a tree, to collect insects from the tree.
