DETAILED DESCRIPTION OF THE INVENTION

[0058] The following detailed description is of the best currently contemplated modes of carrying out various embodiments of the invention. The description is not to be taken in a limiting sense, but is made for at least the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0059] With reference to FIGS. 1, 1A and 1B, an apparatus 100 used for biologically controlling agricultural pests is shown that can be securely attached to an optional unmanned aerial vehicle (UAV) 800 as illustrated in FIGS. 1A, 13A and 13B. In use, the apparatus 100 can advantageously spread essentially beneficial biological organisms 7 or materials 9 over a selected biological target or target location such as agricultural crops in order to reduce damage caused by the agricultural pests. An example of agricultural pests or organisms known to cause damage to agricultural crops, but not limited to, is mites such as spider mites and insects.

[0060] As shown in FIGS. 2, 2A, and 2C, the apparatus 100 includes a container 200 (also referred to as hopper 200) that holds the essentially beneficial biological organisms 7 or materials 9 that are used to control and/or eradicate agricultural pests. The hopper 200 also includes first 10 and second 20 ends and an opening 10 at the first end 10 of the hopper 200 for insertion of the beneficial organisms 7. In addition, the hopper 200 includes a dispenser port 30 located substantially at the second end 20 of the hopper 200 for dispensing the beneficial organism or materials on a biological target or target location to be treated. For example, the hopper 200 could contain predatory mites such as the phytoseiulus persimilis that feed on spider mites and their eggs. Also, existing systems include predatory mites being enclosed loosely in the hopper 200 or mixed with vermiculite for enhancing the suitability of their environment. Additionally, the hopper or any other container can accommodate various other carriers in conjunction with the biological organisms or materials 9. For example, the hopper 200 could contain a mixture of the predatory mites mixed with sawdust or the like or even mixed with both sawdust and vermiculite in order to enhance their environment.

[0061] Referring still to FIGS. 2 and 2A, the hopper 200 further includes spinner motor screw holes 22a which will be aligned with the spinner motor mount screw holes 22b (See FIGS. 6 and 6B) when the spinner motor mount connection area 45 (See FIGS. 6 and 6B) is securely connected to the second end 20 of the hopper 200. The hopper 200 will also have mounting screw holes 35a which will be aligned with the auger motor mount screw holes 35 (See FIGS. 3 and 3A) for securing the auger motor mount 300 to the hopper 200. The auger motor mount will 300 (See FIGS. 3 and 3A) will be mounted to an auger motor mount area 10a that is located within the hopper 200 as shown in FIG. 2.

[0062] In FIGS. 3 and 3A, an auger motor mount 300 is shown which will be mounted within the hopper 200 as previously described above. The motor mount 300 will have fastening insert holes 33 for allowing an optional lid 700 to be mounted to the motor mount 300 when it is inserted in the hopper 200 and screws inserted into the screw insert slots 33a located on the lid 700. Moreover, the auger motor mount 300 will also have auger motor mount screw holes 35 (See FIGS. 3 and 3A) which will be aligned with the mounting screw holes 35a for securing the auger motor mount 300 to the hopper 200.

[0063] Referring still to FIGS. 3 and 3a, the auger motor mount 300 includes a first motor holding area 32 for securing and holding a first motor 38 (See FIG. 12A) that will beneficially drive an auger 400 mounted to said motor 38 (See FIGS. 4, 4A and 4B). Additionally, the auger 400 will be inserted through an auger insertion hole 32a and mounted to the first motor 38 by means of a shank hole 45 as illustrated in FIGS. 4 and 4A. Further, the auger 400 includes spurs 40 for connecting and securing spiral like wire brushes 47 as depicted in FIGS. 4C and 4D.

[0064] Referring now to FIGS. 5 and 5A, a spreader agitating device 500 is shown. The spreader agitating device 500 is mounted to and driven by a second motor 53 (See FIG. 12) for spreading the essentially beneficial biological organisms 7 or materials 9 over the biological target to be treated. The second motor 53 is also secured and held in a second motor holding area 50 that is located on the spreader motor mount 600 as shown in FIGS. 6 and 6A.

[0065] In use, the spinner motor mount connection area 45 of the spreader mount 600 is securely mounted to the second end 20 of the hopper 200. In this configuration, the spreader agitating device 500 is connected to the second motor 53 by fastening the agitating connecter 50A to the second motor 53.

[0066] Alternatively, one embodiment of the invention includes a lid 700 for securing the essentially beneficial biological organisms or materials within the hopper 200 (See FIG. 7). Another embodiment of the invention will include an optional lid 700 that opens on one end and remains closed on the other end (See FIG. 7A). To open the lid 700 on one end, the following components are needed: a hinge 710 (See FIG. 8), a hinge pin 720 (See FIG. 9) and a hinge pin cap 730 (See FIG. 10). Optionally, the hinge 710, hinge pin 720 and hinge pin cap 730 can be fastened to the screw insert slots 33a located on the opening end of the lid 700 for allowing one end of the lid to open and close as shown in FIG. 7A. A further option of the invention allows for a lid lock hinge 11 to be securely fastened to the top portion of the hopper 200 in order to allow the lid 700 to be securely sealed by a fastening mechanism 37 when in the closed position (See FIG. 7).

[0067] In operation, the apparatus 100 is securely mounted to an optional unmanned aerial vehicle (UAV) 800 (See FIGS. 1, 1A, 13A, 13B, and 13C) with essentially beneficial biological organisms 7 (also referred to as biological control agents) or materials 9 securely enclosed within the hopper 200. After the biological organisms such as predatory mites are secured in the hopper, the UAV will be flown over an agricultural crop (i.e., biological target) such as a strawberry field or a state legalized marijuana field and the apparatus 100 will then advantageously spread the essentially beneficial biological organisms 7 or materials 9 over the selected biological target.

[0068] Referring still to the apparatus 100 in operation, the essentially beneficial biological organisms 7 or materials 9 are released from the hopper 200 when the auger 400 is spinning and the spiral like wire brushes 47 advantageously push or agitate the essentially beneficial biological organisms out and through the dispenser port 30. After the essentially beneficial organisms or materials (e.g., predatory mites such as persimilis mites) have been released from the dispenser port 30, they are beneficially spread over the target location by the spreader agitating device 500 as it spins while the apparatus 100 is flying over the target. Optionally, the flight path of the apparatus 100 can be advantageously controlled by a global positioning system (GPS) in order to uniformly apply the essentially beneficial biological organisms on and/or over the selected targets to be treated.

[0069] Turning now also to FIGS. 15A and 15B, in an alternative embodiment, dispersion components, including hopper 200, auger mount 300, auger 400, and spreader 500 are replaced with an alternative dispersion unit. Under this embodiment, the apparatus 100 includes drum 900. Drum 900 may comprise a hollow cylindrical container with an inner cavity 905 and defined by a circular base and an adjacent side wall. The side wall will optimally comprise a series of openings 907 sized such that essentially beneficial biological organisms 7 or materials 9 may freely pass through. Drum 900 may be mounted to an unmanned aerial vehicle UAV. Drum 900 may include a cap 910 for securing the essentially beneficial biological organisms 7 or materials 9 within the inner cavity 905 (See also FIG. 16). Cap 910 may also include a fastening means 914, such as clips or screws in order to secure cap 910 to the top of drum 900. Cap 910 may also include a motor holding area 912 which may couple with motor 38.

[0070] Optionally, the motor 38 can be securely fastened or mounted to a motor housing mount 38a which is securely fastened or mounted to a drum platform 900a (See FIGS. 16A-16B). In one embodiment, the drum platform 900a is advantageously coupled to a plurality of platform mounts 900b which are securely fastened to the drone or the aerial device (See FIGS. 16B-16C).

[0071] In another embodiment, drum 900 is aligned such that the central axis of the drum is substantially vertical or perpendicular to the ground. During operation, motor 38 rotates 920 drum 900. As drum 900 rotates, the centrifugal force 925 of the rotation 920 urges essentially beneficial biological organisms 7 or materials 9 radially outwards in the inner cavity 905. The centrifugal force 925 should be applied to the extent that essentially beneficial biological organisms 7 or materials 9 are urged through the series of openings 907. Porous or mesh screens 909 may be applied to openings 907 so that essentially beneficial biological organisms 7 or materials 9 will not pass-through openings 909 during non-operation but will allow the passage of essentially beneficial biological organisms 7 or materials 9 only when the centrifugal force 925 is applied.

[0072] In an alternative embodiment, cylindrical drum 900 is arranged horizontally, such that the central axis of the drum 900 is substantially parallel to the ground, as seen in FIG. 15B. In this embodiment, gravity will urge essentially beneficial biological organisms 7 or materials 9 to a bottom area of the side wall of the inner cavity 905. During operation, motor 38 will rotate 920 drum 900 about its central axis. As drum 900 rotates, essentially beneficial biological organisms 7 or materials 9 contained in the inner cavity 905 will continue to roll towards the bottom area of the side wall, exposing essentially beneficial biological organisms 7 or materials 9 to openings 907 as openings 907 pass by the underside of the drum 900 during rotation. As essentially beneficial biological organisms 7 or materials 9 passes over openings, essentially beneficial biological organisms 7 or materials 9 will be released from drum 900 onto the desired surfaces. On occasions, the essentially biological organisms 7 or materials 9 in the drum will arrange itself due to biological preferences. For example, some organisms will migrate to the top of the group of the essentially biological organisms 7 or materials 9 in order to get access to air or light, or in some instances naturally gravitate upwards. Accordingly, the rotation of drum 900 serves to mix the biological organisms 7 or materials 9 so that different materials are all evenly distributed for dispersion.

[0073] These embodiments have the advantage of dispersing biological organisms 7 or materials 9 through movement of the drum 900, rather than an auger in a drum or container. Granular materials such as the biological organisms 7 or materials 9, have a tendency to result in an equilibrium state where the grains are more resistant to movement, such as a jammed state. Accordingly, it is beneficial to apply a force to the granular materials to unjam them. Referring again to FIG. 15b, for example, as Drum 900 rotates, gravity acting on the biological organisms 7 or material 9 causes the biological organisms 7 or materials 9 to experience a tumble-like motion. This motion acts to separate grains from each other and eliminate or minimize any jammed grains.

[0074] It is envisioned that in order to minimize a worker's need to interact with the biological organisms 7 or materials 9, hopper 200 or drum 900 may be unitized and sold as cartridges pre-filled with the biological organisms 7 or materials 9. This allows for a standardized mixture of the biological organisms 7 or materials 9 to be used without individual workers needing to measure and mix organisms prior to each use. In such an embodiment, hopper 200 or drum 900, would be filled with a mixture of the biological organisms 7 and or materials 9, and the cap secured. A thin removable covering may then be applied to the exterior of the hopper 200 or drum 900 to cover the dispersing ports. Accordingly, the biological organisms 7 or materials 9 will be secure in the hopper 200 or drum 900 during transport or non-use. Once the device is to be used, the removable covering can be removed, and exposing the dispersing ports so the biological organisms 7 or materials 9 may be released to the target area.

[0075] In one embodiment of the invention, the device 100 can be used to spread predatory mites on or over strawberry fields in order to control and/or to eradicate spider mites (i.e., prey).

[0076] In an alternative embodiment of the invention, the device 100 can be used to apply and/or spread various types of other materials. These materials include, but are not limited to, the application of seeds, dry chemicals such as herbicides, pesticides, fungicides, dry fertilizers, and the application of agricultural amendments.

[0077] The term “prey” refers to mites that are present specifically as prey for the predatory mites to feed on. The predatory mites may feed on any life stage of the prey mite, for example eggs, juveniles or adults.

[0078] The term “predatory mites” refers to mites that are predators of any pest. In particular, it refers to mites that are predators of crop pests. They may be predators of pests such as insects, nematodes or arachnids. Typically, the predator mites will be useful for control of the common crop pests such as thrips, spider mites and whitefly. Most predatory mites belong to the family Phytoseiidae (order Acarina). The most common predators used for biological control are Amblyseius swirskii, Phytoseiulus persimilis, Amblyseius californicus, Amblyseius cucumeris, Amblyseius degenerans, Hypoaspis miles, Aphidoletes aphidimyza, Aphelinus abdominalis, Aphidius colemani, Chrysoperla carnea, Aphidius ervi, and Diglyphus isaea, all of which may be used in conjunction with the present invention.

[0079] Phytoseiulus persimilis is advantageously used in biological control programs for two-spotted spider mites (Tetranychus urticae), and related Tetranychus species. The mites are predators as nymphs and adults, mostly feeding on spider mite eggs and nymphs, but also consuming adults.

[0080] It will be preferable to choose a predator that will not cause damage to the crop plant itself. The predator mites may be used to control pests on one or more of the crop plants in the following, non-exhaustive list: tomato, sweet pepper, chilli pepper, aubergine, cucumber, beans, squash, melon, strawberry, raspberry, banana, papaya, apple, pear, plum, grape, rose, chrysanthemum, Gerbera, Begonia, Cyclamen, Corn, Poinsettia, Citrus, Skimmia, Choiysia, Daphne and Magnolia. Further, the crop can be selected from the group consisting of peppers, cucumbers, aubergines, roses, gerberas, melons and beans.

[0081] According to a further embodiment of the invention, there is provided at least one predatory mite, and at least one prey mite to act as a food source for said predatory mite.

[0082] It should be understood that the foregoing relates to various embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention. It should also be understood that the present invention is not limited to the designs mentioned in this application and the equivalent designs in this description, but it is also intended to cover other equivalents now known to those skilled in the art, or those equivalents which may become known to those skilled in the art in the future.

INDUSTRIAL APPLICABILITY

[0083] The invention pertains to an apparatus and method used to biologically control agricultural pests using biological organisms or materials, which may be of value or importance to various industries, such as the agricultural industry or producers of ornamental flowers, or even home gardeners.
