Tractor mountable apparatus for collecting and destroying insects from multiple rows of plants, such as cotton, as the tractor passes along the rows is disclosed. The apparatus comprises a supporting frame including longitudinal support members mountable upon the front end of a tractor to project forward rather than rearwardly thereof, and transverse support members carried by the longitudinal support members. A plurality of insect destroying open topped metal pans are suspended from the transverse support members and are spaced to pass between rows of plants as the apparatus moves through a field. Each of the pans has an elongated perforated gas fired burner for heating the pan and for completely incinerating insects falling into the pans and laterally extending resilient agitator means or flexible aprons mounted thereon for knocking insects from the side branches of the plants. A vertically adjustable transverse agitator rod extends across the entire width of the apparatus directly above the pans for engaging the tops of plants and for knocking insects therefrom into the pans. Each of the pans is mounted to swing rearwardly and upwardly when encountering a stone or other low lying ground object, and motor operated means is provided for simultaneously raising and lowering all of the pans at the will of an operator.
