Description
BRIEF DESCRIPTION OF THE DRAWINGS
[0011]
[0012]
DETAILED DESCRIPTION
[0013] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the drawings, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.
[0014] Embodiments of the present disclosure relate to compositions used for controlling, killing, inhibiting, repelling, or mitigating pests. In particular, the disclosure relates to compositions that include a pyrone, a pyrethroid, a neonicotinoid, an organophosphate, an enzyme inhibitor, or a combination thereof. Some embodiments relate to methods of making the compositions. Some embodiments relate to methods of controlling, killing, inhibiting, repelling, or mitigating pests by applying the compositions described herein to an environment or region where pests are to be controlled.
[0015] By promoting the continued influx of sodium ions across the membrane of neurons in insects, pyrethroid insecticides cause hyper-excitability of the insect nervous system, contributing to spastic paralysis and inevitably death. Because pyrethroids readily migrate across the insect cuticle and diffuse evenly throughout the insect, they exert their toxic effects minutes after the target insect comes into contact with these compounds. One important symptom of pyrethroid intoxication is rapid immobilization (knockdown). Unlike some slow acting insecticides, pyrethroids are ideal for public health vector control because this knockdown effect prevents mosquitoes from feeding on future hosts. This property is also important for control of agricultural pests to prevent them from consuming any portion of the plant. Moreover, it likely contributes to the mortality of the intoxicated insect through numerous mechanisms, for example, desiccation, susceptibility to predation, and the inhibition of grooming which mitigates the accumulation of fungal spores on the insect. This knockdown effect is a crucial consideration in the development of future insecticidal formulations that contain natural products with novel modes of action.
[0016] One of the hurdles to identifying new insecticidal formulations is ensuring that these new mixtures will be fast-acting and cause high mortality while simultaneously being safe for application in residential areas, for example. Although many toxic synthetic insecticides exist which cause rapid nervous system intoxication, their high toxicity to humans and other vertebrates and relatively long half-lives in the environment prevents them from being viable avenues to follow in the search for new insecticidal formulations. It is paramount to identify candidate insecticides which have low mammalian toxicity, degrade rapidly, and still quickly immobilize and kill insects. Some compounds within plant essential oils possess these prerequisite characteristics (Isman 2011). To date, the understanding of plant essential oil mode of action is diverse and complex and suggests that several molecular targets are involved. For example, the potency of patchouli oil has been shown across a range of insects and its active component is likely a pyrone molecule that is different from the terpenoids present in plant essential oils (Chen 2017). In Drosophila melanogaster, the binding affinities of select terpenoids to a heterologously expressed tyramine receptor correlate directly with the toxicity of these terpenoids in the wild-type insect (Enan 2005). Also, significant specific binding of various terpenoids occurs at the Periplaneta americana octopamine receptor (Enan 2001). Plant essential oil components also exert their effects through other modes of action, for example by binding to GABAA receptor ion channel as antagonists, as acetylcholinesterase inhibitors, and as nicotinic acetylcholine receptor blockers (Tong and Coats 2010, Anderson and Coats 2012, Tong et al. 2012). Because of their diverse modes of action and the low likelihood of cross-resistance with current insecticides on the market, plant essential oils and their components may prove to be valuable tools in the pest management arsenal. Because of the rapid development of resistance to many of the currently available insecticides on the market, these plant essential oil components may be viable alternatives in future insecticidal formulations.
[0017] There are three major mechanisms by which resistance can occur: reduced penetration of the pest by the pesticide; metabolism of the insecticide (resulting in detoxification); and target-site insensitivity. These resistance mechanisms may exist individually in an insect, but are often found in combination where the overall resistance offered is substantially higher; this situation is referred to as multi-factorial resistance.
[0018] Many insects possess detoxification systems, which evolved originally to protect the insect from natural toxins in the environment. Metabolism of the insecticide may occur before it reaches its target-site when it comes into contact with those detoxifying enzymes that render it either less toxic or more easily excreted, or both. The most important enzyme systems involved in insecticide resistance include the groups a) mixed function oxidases, b) glutathione S-transferases and c) esterases. Resistance resulting from enhanced activity of one or more of these enzyme groups has been found in several insect species.
[0019] Insect detoxifying enzyme systems can be studied either in vivo by conventional bioassays, or in vitro by biochemical assays. In conventional bioassays, there is widespread employment of synergists such as DEF (S,S,S-tributyl phosphorothioate) and TPP (O,O,O-triphenyl phosphate). These are compounds that significantly enhance the toxicity of an insecticide, although they may be virtually non-toxic when used alone. Insecticide synergists act by inhibiting metabolic enzymes. Mortality differences in a bioassay, using a pesticide in the presence or absence of a synergist, should indicate whether a putative metabolic enzyme is involved in resistance.
[0020] Some embodiments provided herein relate to formulations containing a 2-pyrone molecule which include the compounds represented by the general Formula (I)

[0021] In some embodiments, the compositions further include at least one insecticide and/or at least one enzyme inhibitor that may be referred to as a synergist. Some embodiments provided herein relate to methods of making the compositions. Some embodiments provide herein relate to methods of applying the compositions, wherein the compositions kill invertebrates, including, for example, insects, arachnids, and/or their larvae and has minimal effects on other species, such as mammals, fish, or fowl. In some embodiments, the compositions are applied at relatively low concentrations, which is effective over a comparatively long period of time such as at least 24 hours.
[0022] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. The use of the term including as well as other forms, such as include, includes, and included, is not limiting. The use of the term having as well as other forms, such as have, has, and had, is not limiting. As used in this specification, whether in a transitional phrase or in the body of the claim, the terms comprise(s) and comprising are to be interpreted as having an open-ended meaning. That is, the above terms are to be interpreted synonymously with the phrases having at least or including at least. For example, when used in the context of a process, the term comprising means that the process includes at least the recited steps, but may include additional steps. When used in the context of a compound, composition, or device, the term comprising means that the compound, composition, or device includes at least the recited features or components, but may also include additional features or components.
[0023] As used herein, any R group(s) represent substituents that can be attached to the indicated atom. R groups as described herein with respect to the pyrone compound (including the compound as set forth in Formula (I)), are defined with the symbols V, W, X, Y, and Z. The description of R groups applies to these groups defined in the compounds described herein. An R group may be substituted or unsubstituted. If two R groups are described as together with the atoms to which they are attached forming a ring or ring system, it means that the collective unit of the atoms, intervening bonds and the two R groups are the recited ring. For example,
[0024] It is to be understood that certain radical naming conventions can include either a mono-radical or a di-radical, depending on the context. For example, where a substituent requires two points of attachment to the rest of the molecule, it is understood that the substituent is a di-radical. For example, a substituent identified as alkyl that requires two points of attachment includes di-radicals such as CH.sub.2, CH.sub.2CH.sub.2, CH.sub.2CH(CH.sub.3) CH.sub.2, and the like. Other radical naming conventions clearly indicate that the radical is a di-radical such as alkylene or alkenylene.
[0025] The term halogen or halo, as used herein, means any one of the radio-stable atoms of column 7 of the Periodic Table of the Elements, including, for example, fluorine, chlorine, bromine, or iodine.
[0026] As used herein, C.sub.a to C.sub.b in which a and b are integers refer to the number of carbon atoms in an alkyl, alkenyl or alkynyl group, or the number of ring atoms of a cycloalkyl or aryl group. That is, the alkyl, the alkenyl, the alkynyl, the ring of the cycloalkyl, and ring of the aryl can contain from a to b, inclusive, carbon atoms.

Example 6
[0097] Spatial repellency of pogostone was assessed on pyrethroid-susceptible (Orlando) and pyrethroid-resistant (Puerto Rico) strains of Aedes aegypti female adult mosquitoes. Repellency bioassays were performed using a static air repellency chamber, which has been described previously (Schultz, 2006; Peterson, 2018). Briefly, the repellency chamber consists of a clear glass cylinder 600 mm in length with an inner diameter of roughly 85 mm laying horizontally. One end of the cylinder is capped with an untreated 90-mm filter paper (Whatman No. 1) contained in a 90-mm inner diameter glass petri dish, and sealed with tape to remain closed. The other end is capped in the same manner, except the filter paper has been treated with 1 mL of a 0.5% (w/v) solution of a monoterpenoid ester in acetone, resulting in 78.6 g/cm.sup.2 of repellent on the filter paper. The solution was added to the filter paper evenly and at a rate such that the evaporation of acetone prevents loss of compound from dripping, and the acetone was allowed to evaporate at room temperature for a further 10 minutes before use for the short-term repellency assay, or for an additional five hours under open air in ambient conditions in the case of long-term repellency studies. Shortly after placing the filter papers on the end of the tube, twenty (not blood fed) female Culex pipiens mosquitoes were anesthetized with carbon dioxide, and placed into the tube via a 20-mm hole halfway down the length of the tube, and the hole was sealed. This process is performed with as little disturbance to the air in the tube as possible. The distribution of mosquitoes between the treated and untreated sides was then noted at 15, 30, 60, 90, 120, and 150 minutes after placement into the tube. Repellency ratio of Orlando or Puerto Rico mosquitoes was recorded as a proportion of the number of mosquitoes on the treated side of the tube compared to the whole tube [number of treated side/total number throughout entire tube] at 1 hour after introducing the treated filter papers.

[0101] In the foregoing description, specific details are given to provide a thorough understanding of the examples. However, it will be understood by one of ordinary skill in the art that the examples may be practiced without these specific details.
[0102] In at least some of the described embodiments, one or more elements used in an embodiment can interchangeably be used in another embodiment unless such a replacement is not technically feasible. It will be appreciated by those skilled in the art that various other omissions, additions and modifications may be made to the methods and structures described above without departing from the scope of the claimed subject matter. All such modifications and changes are intended to fall within the scope of the subject matter, as defined by the appended claims.
[0103] With respect to the use of substantially any plural or singular terms herein, those having skill in the art can translate from the plural to the singular or from the singular to the plural as is appropriate to the context or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
[0104] The embodiments illustratively described herein suitably may be practiced in the absence of any element(s) not specifically disclosed herein. Thus, for example, in each instance herein any of the terms comprising, consisting essentially of, and consisting of may be replaced with either of the other two terms. The terms and expressions which have been employed are used as terms of description and not of limitation, and use of such terms and expressions do not exclude any equivalents of the features shown and described or portions thereof, and various modifications are possible within the scope of the technology claimed. The term a or an can refer to one of or a plurality of the elements it modifies (e.g., a reagent can mean one or more reagents) unless it is contextually clear either one of the elements or more than one of the elements is described. The term about as used herein refers to a value within 10% of the underlying parameter, and use of the term about at the beginning of a string of values modifies each of the values. For example, a weight of about 100 grams can include weights between 90 grams and 110 grams. Further, when a listing of values is described herein (e.g., about 50%, 60%, 70%, 80%, 85% or 86%) the listing includes all intermediate and fractional values thereof (e.g., 54%, 85.4%). Thus, it should be understood that although the present technology has been specifically disclosed by representative embodiments and optional features, modification and variation of the concepts herein disclosed may be resorted to by those skilled in the art, and such modifications and variations are considered within the scope of the embodiments.
[0105] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
[0106] As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible sub-ranges and combinations of sub-ranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as up to, at least, greater than, less than, and the like include the number recited and refer to ranges which can be subsequently broken down into sub-ranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 articles refers to groups having 1, 2, or 3 articles. Similarly, a group having 1-5 articles refers to groups having 1, 2, 3, 4, or 5 articles, and so forth.
[0107] While preferred embodiments described herein have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the description. It should be understood that various alternatives to the embodiments described herein may be employed in practicing the embodiments. It is intended that the following claims define the scope of embodiments provided herein and that methods and structures within the scope of these claims and their equivalents be covered thereby.
