Abstract
An adhesive trap for entrapping pests such as insects such as flying or crawling insects, or other small creatures includes a corrugated panel defining a plurality of channels connected by convex peaks. For example, the corrugated panel, or a plurality of corrugated panels, may be configured and/or assembled to define a pillar or the like. An insect adhesive, such as pressure-sensitive adhesive, is adhered only in the plurality of channels, such that the convex peaks of the corrugated panel are free of adhesive. The adhesive trap is effective at capturing target insects, and the adhesive-free outer portions facilitate handling of the traps without contacting the adhesive and reduces the risk and likelihood of inadvertently ensnaring or adhesively engaging larger, non-target creatures.

DETAILED DESCRIPTION
[0035] Examples of an adhesive trap configuration are disclosed, which provides one or more corrugated surfaces or panels, wherein the adhesive panels are easier to handle and are less likely to entrap larger, non-target animals or to be damaged by inadvertent interaction with larger animals or the like. As used herein a corrugated panel (or corrugated sheet) is defined conventionally as a panel “shaped into wavy folds or alternating furrows and ridges” (see www.dictionary.com). The adhesive trap construction disclosed herein may be applied to a variety of pests, for example arthropods (e.g., insects), arachnids (e.g., spiders), reptiles, amphibians, small mammals (e.g., rats, mice, etc.), and the like, providing a new tool for combatting pestiferous and/or disease-vector critters.
[0036] Different corrugated panels or surface structures are contemplated. For example, a common corrugated material on the market is a single face corrugated fiberboard (for example, “corrugated paper-based cardboard”), having a fluted corrugated surface on one side of the sheet and a flat linerboard on an opposite side of the sheet. The flat bottom linerboard can be replaced with a single, double, or triple wall board to increase the strength of the overall cardboard structure. In some embodiments, the corrugated surface may also be made of relatively sturdy materials, such as fiberglass, plastic, or glass, and may omit the linerboard. These materials can have any level of opacity, can be translucent, and/or can be clear. In some embodiments, materials can have color or be colorless.

[0043] The size and shape of the channels C in the corrugated panels, and type and quantity of adhesive provided in the channels C may be optimized for a particular application. For example, the pest 90 is shown in
[0044] Optimal sizes and shapes of the corrugated flutes may also take into consideration typical human finger sizes to minimize user entanglement, as well as glue application requirements, coating area, etc. Common sizes of single-face corrugated flutes (paper cardboards) are A, B, C, E, and F flutes, the characteristics of which are set forth in Table 1 below. Flute thickness (height), wavelength (pitch) as well as paper (or plastic) thickness for flutes and flat linerboard are variables that can be adjusted to be optimized for different target insects and/or applications. For sturdy plastic, glass or fiberglass corrugated surfaces, no linerboard is needed. For example, a corrugated panel may be stood upright or hung with the adhesive applied in furrows on both sides of the panel; thus, the flute types and sizes for the single-face paper cardboards are contemplated for the more rigid materials without linerboard.

[0045] In some embodiments, the corrugated panel is flexible, and is configured to wrap around a fixed object, for example a tree trunk, or a movable object such as a movable container or post. For example, the corrugated panel may be formed as a flexible elongated panel, which is configured to be installed as a spiraled wrap around the movable or fixed object. It is contemplated, for example, that a corrugated panel may include adhesive in the channels of one or both sides of the panel and is wrapped around the base of the object. In some embodiments it may be preferable to install corrugated adhesive panels in alternating arrangements with adhesive applied on opposite sides of adjacent panels. The particular pattern of the adhesive placement may be configured to the specific behavioral characteristics of the pest targeted by the particular application.
[0046] In representative embodiments, the adhesive may be any pressure sensitive adhesive (“PSA”), or other type of glues that will adhesively ensnare a target insect. It is contemplated that the adhesive may be applied using (i) one or more spray heads (air spray or airless spray), (ii) wheel/roller systems, (iii) jetting systems, (iv) slot applicators/extruders, and/or (v) brush and/or trowel systems, for example. Other adhesive application systems as are known in the art may alternatively be used, including applying or printing narrow strips of adhesives or adhesive tapes into the furrows. In another embodiment an adhesive is applied to the entire surface and non-adhesive blocking strips are applied over the peaks of the corrugations that block the adhesive from adhering to the peaks.
[0047] In one method of making the adhesive trap with the desired glue area/thickness and patterns, glue is applied to the furrows in strips as a thin layer of adhesive membrane, e.g., thickness range from 1-60 mil, to cover a bottom ¼ to ½ or ¾ of the valley-ridge sloped surface area, in the grooves, leaving the corrugation top section (upper ridge section) with no adhesive. For example, the non-adhesive portions may comprise ¼ or more total corrugation area. In some embodiments, an adhesive may be applied as a thick bead having a diameter, for example, ⅓ to ½ or less of the groove height. Although uniform spacing of the corrugated surfaces are shown, it is contemplated that the corrugation spacing may be non-uniform. In some embodiments the ridge sections may be non-parallel, for example expanding in a fan-like arrangement.
[0048] Regardless of the corrugation types (sizes), the glue area along with the thickness of the glue in the groove should be sufficient to ensnare or capture target pests but restricted to the channels of the corrugated sheet or panel such that the corrugated panel may be handled by a user without contacting the adhesive directly, and to avoid or reduce the risk of contact by feathers or body parts of non-target creatures such as birds or bats. For example, the selected corrugation sizes or combination of corrugation sizes, and the glue area/thickness may be selected to engage multiple insect legs (at least 2) of a target insect no matter where the target insect lands on the corrugated surface.
[0049] It is contemplated that the corrugated or fluted panels may have color and/or pattern combinations providing a visual attractant for target insects, such as flies and/or social wasps. Examples of visual attractants on flat surfaces are disclosed in U.S. Pat. No. 9,015,988, to Zhang et al., which is hereby incorporated by reference in its entirety. It is believed that the three-dimensional characteristics of visual attractants on a corrugated surface will likely improve the efficacy of the attractant to target insects. One certain embodiment of the adhesive trap providing a visual attractant for target insects is shown in
[0050]
[0051] A plurality of the panels 110 may be assembled or manufactured unitarily such as a hexagonal pillar 210 shown in
[0052] In some embodiments, the corrugated panel may be formed as an elongated flexible ribbon or tape that may be wrapped in a spiraling arrangement around an existing structure, for example a tree, fencepost, light post, power pole, or the like. For example, it is contemplated that spacers (not shown) may be fixed to an inner surface of the elongated flexible ribbon or tape, such that the flexible ribbon is spaced away from the structure, to provide insect (or other pest) access to space between the structure and the ribbon. An adhesive applied only to the side of the flexible ribbon facing the structure would provide a non-adhesive outer face, and an inner surface that does not adhere to structure.
EXAMPLES
[0053] Two trapping efficacy experiments were carried out in a laboratory wind-tunnel to compare the adhesive trap of the present disclosure shown in
[0054] Materials & Methods
[0055] Insects
[0056] The house flies were received as pupae from Beneficial Insectary in Redding, California. The flies were reared to adults on a 14:10 hour light to dark schedule at about 20-24° C. with roughly 10-15% Relative Humidity.
[0057] Traps
[0058] An adhesive trap formed with a flat corrugated cardboard panel (9.7 cm×20 cm) Attractive colors (blue/green), patterns, and contrasts were printed on the corrugated surface to form a visual attractant. An adhesive coating was applied only in the flute valleys of the corrugated panel. An example of the adhesive trap that was used in these experiments is shown in
[0059] The two Alpha Scents Inc. Sticky Traps (see
[0060] Testing Chamber: Wind-Tunnel
[0061] Both experiments (Experiments 1 and 2) were tested in a laboratory wind-tunnel without the airflow running. The wind-tunnel is constructed of clear acrylic panels with metal frame material and is about 200 cm×82.5 cm×82.5 cm in size.
[0062] Testing Procedures
[0063] Experiment 1 tested an adhesive trap vs. Yellow Sticky Card Trap (Alpha Scents, Inc.). These two sticky traps were attached centered to a white corrugated plastic board (25 cm×33 cm) side by side about 2 cm apart. Experiment 2 tested the corrugated panel vs. Clear Window Sticky Trap (Alpha Scents, Inc.). These two sticky traps were attached centered to a glass pane (27.5 cm×35 cm) side by side about 2 cm apart. For each test, the trap holding board (plastic or glass) was hung 13.5 cm from the ceiling on one side of the wind-tunnel at 30 cm away from the end while 1-2 jars of (approximately 400) house flies were released from the other side into the wind-tunnel at 25.5 cm from the end for the first 10 minutes of testing. The fly jar was removed from the wind-tunnel after 10 minutes.
[0064] Observations were made for the first 15 minutes of testing to see how the flies react to the sticky substrates, and the testing was continued for a total of 2 hours. After 2 hours, the white corrugated board or the glass pane was removed from the wind-tunnel to count how many house flies were caught on each trap. The remaining flies were vacuumed out of the wind-tunnel after each run. For the next round of testing, the positions of the treatments were switched so that if the adhesive trap was on the right side it would be on the left side, and the Alpha Scents, Inc. trap would go from the left side to right side. This would eliminate or reduce any positional bias that might appear during the testing. This next test run was completed in the same way as described above in the procedure. The numbers of flies caught from these two test runs were recorded and pooled together by treatment as a full replicate for the data analysis using the Paired t-Test with SPSS 29.0 for Microsoft Windows. For each experiment, 6 full replicates were completed.
[0065] Results
[0066] In Experiment 1, a total of 1535 house flies were captured in 6 full replicates of testing in the wind-tunnel. The adhesive traps caught on average 180.17 flies per full replicate, which was approximately 2.38 times (significantly) higher than did the Alpha Scents, Inc. Yellow Sticky Card Traps (see

[0067] In Experiment 2, a total of 1714 house flies were captured in 6 full replicates of testing in the wind-tunnel.

[0068] In both experiments, the special color combination, pattern, and contrast on the adhesive traps seemed to be strongly attractive to house flies compared to the clear or solid yellow color from the Alpha Scents, Inc. traps. Almost all the house flies that landed on the adhesive traps were caught even though only the valleys of the corrugated surface were coated with adhesive. As observed, an adhesive trap according to one or more aspects of the present disclosure and including a suitable combination of flute size, glue area/thickness, and size of target insect species would ensure multiple insect legs (at least 2) of a target insect to touch and be ensnared by the adhesive no matter where the target insect lands on the corrugated surface.
