General Description:

• The circle trunk trap is a generic trap that is used in conjunction with lure dispensers to attract pecan weevils or other insects. The goal of this requested trap is to modify the existing circle trunk trap so that it is capable of capturing Spotted Lanternfly.

• Length of effectiveness:

The trap should be weather-resistant, withstand sun and able to be re-used for several trapping seasons.

Description of trap physical properties:

• Trap

The trap is made of flexible screen (See Screen_Flat_drw.PDF) and can be wrapped around the trunk of a tree in a cone or funnel like shape. The screen forms a modified funnel that leads to a collection cup at the top of the funnel. This screen is supported by two struts on opposite sides of the screen (See 18 in support_drw.PDF and 11in support_drw.PDF).

• Collection and funnel modification:

Insects will be collected in a plastic bag that securely attaches to the funnel using a cable tie. A reusable cable tie to be included with each trap is preferred. The bag must affix securely to the cup of the trap and allow for insects caught in the trap to be deposited and stored. Traditionally with the circle trunk trap this is accomplished by a mesh funnel with an opening that is sized to prevent the insect from escaping. In the case of SLF the opening should be 1.75 inches (see Funnel.PDF). The cup will be further modified by the addition of a “tongue” to prevent the bag from collapsing and obstructing the opening (See Scoop_Flat_drw.PDF). The tongue must be produced from Lexan or acetate sheeting that is at least 0.020 inch thick and free of any protective film. This material must be strong enough to hold the bag open when it becomes filled with insects. When attached, the tongue must be able to sit at the “top” of the trap as shown in the photo below to prevent closure of the bag. The end of the cup needs a minimum 0.25-inch flange, so the collection bag does not slide off (see arrow in photo below). See Cup_asm.PDF for complete assembly.

The glue used in the assembly must be strong enough to last for the service life of the trap.

Plastic and glues shall not break down when exposed to sun light, heat or other elements.

Traditional hot glues are not sufficient to maintain the bond between the screen at the neck of the trap and the funnel. An epoxy-type glue is preferred to achieve the strongest bond.

• Trap Hanger

Acceptable versions of trap:

Must be capable of surrounding a 5-inch to 10-inch diameter at breast height. The trap can be affixed by T50 3/8” or ½” staples.
