Description

[Technical field]

[0001] The present invention relates to arthropod control compositions, methods and uses for controlling arthropods, and arthropod control articles containing same. [Background technology]

[0002] Many mammals, including humans, are plagued by arthropod activity. Some arthropods, such as mosquitoes and ticks, are undesirable to vertebrates, such as mammals and especially human subjects, because they bite and can result in itching, disease and / or bacterial transmission, or cause other diseases and / or symptoms. Similarly, other pests indirectly affect human activities or society by eating, infesting, or destroying plant materials used as food, feed, or raw materials. Still further, pests are also responsible for destroying or weakening furniture or structures used or built by humans. The damage can be directly attributable to the arthropods or due to their ability to spread bacteria that cause such problems.

[0003] Arthropod control compositions contain active materials that, when applied to skin, clothing, or other surfaces, can prevent arthropods from landing or climbing on the surface. Arthropod control agents help prevent and control outbreaks of arthropod-borne diseases, such as malaria.

[0004] However, some of the known arthropod control agents and compositions have certain drawbacks because they may have poor effectiveness, i.e. poor olfactory properties, e.g. odorless or bad odor, or only weak arthropod control properties, especially arthropod repellent properties. Summary of the Invention [Problem to be solved by the invention]

[0005] There is a need to provide arthropod control compositions that have both good olfactory properties, i.e. good hedonic effect, and good arthropod control properties, especially arthropod repellent properties.

[0006] The prior art does not disclose or suggest the arthropod control compositions according to the present invention. [Means for solving the problem]

[0032] "Mint oil" includes mint oils defined by CAS numbers 8006-90-4, 68917-18-0, and 8008-79-5, and mixtures of mint oils defined by those CAS numbers.

[0033] "Orange oil" includes orange oils as defined by CAS numbers 8007-80-5, 8016-38-4, 68647-72-3, 68514-75-0, 68606-94-0, and 68916-04-1, and mixtures of orange oils as defined by those CAS numbers.

[0034] "Cinnamon oil" includes cinnamon oil as defined by CAS numbers 8007-80-5 and 8015-91-6, and mixtures of cinnamon oils defined by those CAS numbers.

[0035] In a preferred embodiment of the present invention, the arthropod control composition has a good hedonic profile.

[0036] The inventors have appreciated that it may be desirable for an arthropod control composition to have an acceptable hedonic profile, since the composition may be used in proximity to a consumer and, understandably, an unpleasant hedonic profile may prevent use of the composition.

[0037] The term "arthropod" has its usual meaning to those skilled in the art. Arthropods include invertebrates with segmented bodies and articulated limbs, such as insects, arachnids, and crustaceans. Arthropods typically have a chitinous exoskeleton that is occasionally molted, and a dorsal forebrain connected to a ventral ganglion chain.

[0038] Arthropods in the understanding of the present invention refer to undesirable arthropods, meaning that their presence in the air, on the surface of objects, on the surface of plants, or on the surface of vertebrates, such as human subjects or other mammals, preferably human subjects, is undesirable. Preferably, undesirable arthropods are pest arthropods affecting plants and animals, such as thrips, aphids, beetles, moths, mealybugs, scale insects, etc., more preferably pest arthropods affecting animals, such as ants, termites, cockroaches, flies, etc., even more preferably blood-sucking arthropods affecting vertebrates, such as stable flies, bedbugs, assassin bugs, fleas, lice, mosquitoes and mites, even more preferably mosquitoes and mites.

[0039] Reasons why the presence of arthropods is undesirable include the fact that their presence in the air is unpleasant to the subject, that contact of arthropods on items may transfer disease and / or bacteria, or that arthropods sting the organisms causing itching, transmission of disease and / or bacteria, or that feeding on arthropods may cause other diseases and / or symptoms.

[0040] In a particular embodiment, the arthropod is an insect or an arachnid, preferably an insect.

[0041] The term "insect" has its ordinary understanding by those of ordinary skill in the art. Insects are described by a distinct head, thorax and abdomen, only three pairs of legs, and typically one or two pairs of wings.

[0042] In certain embodiments, the insect is a mosquito, stable fly, bedbug, assassin bug, flea, lice, ant, termite, cockroach, fly, aphid, beetle, thrips, moth, mealybug or scale insect, more preferably a mosquito.

[0043] The term "arachnid" has its usual understanding by those skilled in the art. Arachnids are described as having a segmented body divided into two regions, the front of which has four pairs of legs but no antennae.

[0044] In certain embodiments, the arachnid is a tick, mite, chigger or spider, more preferably a mite.

[0045] Expressions such as "control", "arthropod control", "insect control" or "arachnid control" have their usual meaning to the person skilled in the art.

[0046] "Control" in the context of the present invention defines the ability of the arthropod control composition according to the present invention to attract, deter, kill or repel arthropods, preferably to deter or repel arthropods, and even more preferably to repel arthropods.

[0047] "Attraction" according to the present invention defines the ability of an arthropod attractant composition according to the present invention to increase or promote the contact or presence of arthropods at an arthropod attractant source, such as in the air, on the surface of an article, or on the surface of a vertebrate, such as a human subject or other mammal, preferably at an article, such as a trapping device, to which the arthropod attractant compound or composition has been applied.

[0048] "Repellency" according to the present invention defines the ability of an arthropod repellent composition according to the present invention to minimize, reduce, prevent or prevent the approach or presence of arthropods from an arthropod repellent source, such as in the air, on the surface of an article, or on the surface of a vertebrate, such as a human subject or other mammal, preferably a human subject, to which the arthropod repellent compound or composition is applied.

[0049] "Deterrence" according to the present invention defines the ability of an arthropod deterrent composition according to the present invention to minimize, reduce, prevent, or prevent arthropod contact or presence with an arthropod deterrent source, such as in the air, on the surface of an article, or on the surface of a vertebrate, such as a human subject or other mammal, preferably a human subject, to which the arthropod deterrent compound or composition is applied. Typically, a deterrent effect is demonstrated when used as a feeding deterrent and prevents the pest from continuing to ingest food or lay eggs or make physical contact after an initial feeding of the arthropod deterrent compound or composition.

[0050] "Spatial repellency" according to the present invention defines the ability of the arthropod repellent composition according to the present invention to minimize, reduce, prevent or prevent the approach or presence of arthropods to the arthropod repellent source, such as in the air, on the surface of an article, or on the surface of a vertebrate, such as a human subject or other mammal, preferably a human subject, to which the arthropod repellent compound or composition is applied.Typically, spatial repellency is demonstrated when the spatial repellent compound or composition released, sprayed, scattered or diffused in the air or liquid prevents pests from entering the area where the spatial repellent compound or composition is present.Thus, repellency occurs at a distance, and pests do not necessarily come into direct contact with the treated article or the organism to be protected.

[0051] "Killing" according to the present invention defines the ability of an arthropodicidal composition according to the present invention to kill arthropods in an arthropodicidal source, such as in the air, on the surface of an article, or on the surface of a vertebrate, such as a human subject or other mammal, preferably a human subject, to which the arthropodicidal compound or composition is applied. When the arthropodicidal composition is applied to a plant, animal, or human subject, it is applied in an amount that kills arthropods but does not kill the subject.

[0052] In certain embodiments, the arthropod control composition is an arthropod repellent composition, preferably an insect repellent composition, more preferably a mosquito repellent composition.

[0053] In certain embodiments, the arthropod control source is the surface and / or air surrounding an article, preferably a candle, coil, electric diffuser, wristband, patch, collar, ear tag, clothing, fabric, paper, biochar, cardboard, cellulose pad, mosquito net, screen, curtain, furniture, wall, ground or paint, or the surface of a subject, preferably a vertebrate, such as a human subject or other mammal, preferably a human subject, i.e., the skin of a human subject treated with a product such as a spray, aerosol, cream, roll-on, wristband, lotion, soap, shampoo, sunscreen or patch, or fabric treated with a product such as a laundry powder, liquid detergent, spray, lotion, powder, etc.

[0054] Arthropod control efficacy according to the present invention is determined in mosquitoes using an adapted warm body assay as defined in Kroeber T, Kessler S, Frei J, Bourquin M, Guerin PM. An in vitro assay for testing mosquito controlling compounds employing a warm body and carbon dioxide as a behavioral activator. J Am Mosq Control Assoc. 2010; 26:381-386. Further information is provided in the accompanying examples.

[0055] The control effect, repellency and spatial repellency of the present invention are identified by testing the warm-body assay against the yellow fever mosquito, Aedes aegypti Rockefeller strain. Aedes aegypti is a model organism for control testing and one of the model organisms recommended by the World Health Organization (WHO), because it is a highly aggressive and anthropophilic mosquito species and generally shows low sensitivity to arthropod control compounds.

[0056] Control efficacy observations were performed on host-seeking females of uniform age 5-10 days selected as mentioned in the aforementioned literature. Fasted females tested had access to a 10% sugar solution but no blood feed. Further information is provided in the accompanying examples.

[0057] The published protocol was adapted to automatically count landing mosquitoes using automated counting software instead of manually counting, the number of mosquitoes placed in the test cages was reduced due to size differences by switching from Anopheles gambiae to Aedes aegypti (i.e. 30 mosquitoes instead of 50), and lighting was increased since Aedes aegypti is a diurnal mosquito (i.e. 150 lux instead of 4 lux). Further information is provided in the accompanying examples.

[0058] The control, repellency and spatial repellency of the present invention are also determined by the arm-in-box method adapted from the WHO guidelines for testing mosquito repellency efficacy on human skin (WHO / CDS / NTD / WHOPES / 2009.4). The readiness of 100 hungry female mosquitoes Aedes aegypti to the test substance is evaluated by comparing the results of an untreated arm to a treated arm when inserted three times for 30 seconds (negative control) into a cage (40 x 40 x 40 cm). Further information is provided in the accompanying examples.

[0059] Activity against arachnids, e.g., tick repellents, can be evaluated using the in-vitro hot plate assay protocol defined in Kroeber T, Bourquin M, Guerin PM. 2013. A standardized in vivo and in vitro test method for evaluating tick repellents. Pestic. Biochem. Phys. 107(2):160-168.

[0060] In certain embodiments, the amount and selection of the agent is such that it contributes to, enhances or improves both the arthropod control activity and the hedonic properties of the composition.

[0061] In one embodiment, the arthropod control composition may further comprise an arthropod control co-ingredient. By "arthropod control co-ingredient" is meant an ingredient that can provide additional arthropod control benefits to the arthropod control effect of the compositions described herein.

[0062] In one embodiment, the substances described herein can modify, enhance or improve the arthropod control effect of the arthropod control co-ingredient, for example by reducing the amount of the arthropod control co-ingredient in the composition. This can be particularly beneficial when the arthropod control co-ingredient is harmful to human subjects at a particular dose, or when the arthropod control co-ingredient has poor olfactory properties at a particular dose.

[0068] In one embodiment, the arthropod control composition can further comprise a fragrance component.It is understood that the fragrance component contributes to, modifies, enhances or improves the olfactory properties of the composition, but does not contribute to, enhance or improve the arthropod control effect of the composition.The fragrance components that provide such a hedonic effect and are suitable for use in the composition of the present invention are known in the art and can be easily identified by those skilled in the art.

[0069] The arthropod control composition may further comprise a carrier. By "carrier" is understood a material with which the active compound is mixed or formulated to facilitate its application to the location to be treated or other object, or its storage, transport and / or handling. The carrier may be inorganic or organic, or synthetic, natural. The carrier may be liquid or solid.

[0070] The liquid carrier can be, as a non-limiting example, an emulsifying system, i.e., a solvent and surfactant system, or a solvent that is generally used in perfumery.Normally, a detailed description of the nature and type of the solvent cannot be exhaustive.However, as a non-limiting example, it can be mentioned solvents such as butylene or propylene glycol, glycerol, dipropylene glycol and its monoethers, 1,2,3-propanetriyl triacetate, dimethyl glutarate, dimethyl adipate, 1,3-diacetyloxypropan-2-yl acetate, diethyl phthalate, isopropyl myristate, benzyl benzoate, benzyl alcohol, 2-(2-ethoxyethoxy)-1-ethanol, triethyl citrate, 2-methylprop-1-ene and 2-(2-ethoxyethoxy)ethanol or mixtures thereof, and dipropylene glycol, 2-methylprop-1-ene and 2-(2-ethoxyethoxy)ethanol and mixtures thereof are particularly suitable.

[0071] For compositions comprising a carrier, suitable carriers other than those specified above can also be ethanol, water / ethanol mixtures, limonene or other terpenes, isoparaffins such as those known under the trademark Isopar® (manufacturer: Exxon Chemical), or glycol ethers and glycol ether esters such as those known under the trademark Dowanol® (manufacturer: Dow Chemical Company), for example Dowanol™ DPMA (glycol ether acetate), or Augeo® Clean Multi (isopropylidene glycerol; manufacturer: Solvay), or hydrogenated castor oil such as those known under the trademark Cremophor® RH 40 (manufacturer: BASF).

[0072] Solid carrier is meant to refer to a material to which the arthropod control composition or some elements of the arthropod control composition can be chemically or physically bound. Generally, such solid carriers are used either to stabilize the composition or to control the evaporation rate of the composition or some components. The use of solid carriers is currently used in the art, and it is known to those skilled in the art how to achieve the desired effect. However, non-limiting examples of solid carriers can include absorbent rubber or polymer or inorganic materials, such as porous polymers, cyclodextrins, wood-based materials, organic or inorganic gels, clays, gypsum talc, or zeolites.

[0073] Other non-limiting examples of solid carriers can include encapsulation materials. Examples of such materials can include wall-forming and plasticizing materials, such as mono-, di- or trisaccharides, natural or modified starches, hydrocolloids, cellulose derivatives, polyvinyl acetate, polyvinyl alcohol, proteins or pectins, or other such materials. Encapsulation is a method well known to those skilled in the art and can be carried out by using techniques such as spray drying, agglomeration or even extrusion, or by using techniques consisting of coating encapsulation, including coacervation and complex coacervation techniques.

[0074] As non-limiting examples of solid supports, one may mention in particular core-shell capsules using resins of the aminoplast, polyamide, polyester, polyurea or polyurethane type, or mixtures thereof (all said resins are well known to those skilled in the art), using techniques such as phase separation methods induced by polymerization, interfacial polymerization, coacervation, or the like (all said techniques are described in the prior art), optionally in the presence of polymeric stabilizers or cationic copolymers.

[0075] The resins can be prepared by polycondensation of aldehydes (such as formaldehyde, 2,2-dimethoxyethanal, glyoxal, glyoxylic acid or glycolaldehyde and mixtures thereof) with amines, such as urea, benzoguanamine, glycoluril, melamine, methylolmelamine, methylated methylolmelamine, guanazolo, and mixtures thereof. Alternatively, preformed resins of alkylolated polyamines can be used, such as those available commercially under the trade names Urac® (manufacturer: Cytec Technology Corp.), Cymel® (manufacturer: Cytec Technology Corp.), Urecoll® or Luracoll® (manufacturer: BASF).

[0076] Other resins are those produced by polycondensation of polyols, such as glycerol, and polyisocyanates, such as the trimer of hexamethylene diisocyanate, the trimer of isophorone diisocyanate or xylylene diisocyanate, or the biuret of hexamethylene diisocyanate, or the trimer of xylylene diisocyanate and trimethylolpropane (known under the trade name Takenate®, manufacturer: Mitsui Chemicals Inc.), among others the trimer of xylylene diisocyanate and trimethylolpropane, and the biuret of hexamethylene diisocyanate.

[0077] There are many published articles on encapsulation by polycondensation of amino resins, i.e. melamine-based resins with aldehydes, which already describe the various parameters influencing the production of such core-shell microcapsules, and which are known to those skilled in the art and whose contents are used in the field of the present invention.

[0090] The present invention is further illustrated by the following non-limiting examples. EXAMPLES

[0091] 1. Description of the Arthropod Control Assay Arthropod repellency is tested using the small-scale assay described within this application.

[0092] Warm-body assay for insects, e.g., mosquitoes: Aedes aegypti is a model organism for control testing, and one of the model organisms recommended by the World Health Organization (WHO), because it is a highly aggressive and anthropophilic mosquito species and generally shows low sensitivity to arthropod control compounds.

[0093] The arthropod control efficacy of the compositions according to the invention was evaluated using an adapted warm body assay as defined in Kroeber T, Kessler S, Frei J, Bourquin M, Guerin PM.2010, An in vitro assay for testing mosquito controlling compounds employing a warm body and carbon dioxide as a behavioral activator. J Am Mosq Control Assoc. 26:381-386. In this in-vitro assay, the number of mosquitoes landing on a warm body that mimics an attractant host treated with a test stimulant was measured to evaluate the repellency.

[0094] Published protocols were adapted to count landed mosquitoes using automated counting software instead of manual counting, the number of mosquitoes placed in the test cages was reduced due to size differences by switching from Anopheles gambiae to Aedes aegypti (i.e. 30 mosquitoes instead of 50), and lighting was increased as Aedes aegypti is a diurnal mosquito (i.e. 150 lux instead of 4 lux).

[0095] Fasted females aged 10-12 days with ad libitum access to a 10% sugar solution but no blood feeding were selected for the assay as described in Kroeber et al. (2010). For each substance tested, at least three concentrations ranging from 0.0016% to 1% in ethanol were evaluated for the evaluation of deterrent and repellent properties.

[0096] The hot plate was placed on a sandblasted glass Petri dish (28.3 cm 2), 100 μL of the composition diluted in 3 to 9 different concentrations in ethanol was applied. A control test was performed by applying 100 mL of pure ethanol. For each stimulus, the number of mosquitoes landing on the warm body was counted. The number of mosquitoes landing on pure ethanol was used to normalize the repellency of the other stimuli, i.e., the number of mosquitoes landing during the control is 0% repellency.

[0097] 2. Evaluation of the arthropod control effect of the present invention Preparation of the Fragrance Composition of the Present Invention The inventors prepared fragrance compositions to be tested for arthropod repellency. The fragrance compositions are shown below. Each fragrance was made up to 100% with additional ingredients that contribute to the hedonic profile of the individual fragrance.

[0098] [Table 1]

[0099] [Table 2]

[0100] [Table 3]

[0101] Results of the warm-body assay for insects, e.g., mosquitoes: All six compositions were able to repel more than 95% of mosquitoes when applied at 1% on the attractant (Table 4). Already composition A3 was able to reduce the number of landing mosquitoes by more than 60% when applied at 0.04% on the attractant (Table 4). Even better, at the same dose of 0.04%, compositions A5 and A6 were already able to repel more than 90% of mosquitoes (Table 4).

[0102] Table 4. Repellent efficacy of six compositions against Aedes aegypti in the warm-body assay. Each composition was tested at three different doses applied on the attractant stimulus. The landing number during each control was used as a reference to normalize and calculate the percentage of repellency at the three different doses. As an index, a mean ± SD of 60 ± 12.3 mosquitoes landed on the unprotected attractant stimulus during the 2-minute control test period.

[0103] [Table 4]

[0104] All four compositions were able to repel more than 95% of mosquitoes when applied at 1% on the attractant (Table 5).Already composition B2 was able to reduce the number of landing mosquitoes by more than 50% when applied at 0.04% on the attractant (Table 5).

[0105] Table 5. Repellent efficacy of four compositions against Aedes aegypti in warm body assay. Each composition was tested at three different doses applied on the attractant stimulus. The landing number during each control was used as a reference to normalize and calculate the percentage of repellency at the three different doses. As an index, a mean ± SD of 52 ± 9.2 mosquitoes landed on the unprotected attractant stimulus during the 2-minute control test period.

[0106] [Table 5]

[0107] All five compositions were able to repel more than 95% of mosquitoes when applied at 1% on the attractant stimuli (Table 6). Already composition C3 was able to reduce the number of landing mosquitoes by 60% when applied at 0.04% on the attractant stimuli (Table 6). Even better, at the same dose of 0.04%, compositions C1, C2, C4 and C5 were already able to repel more than 80% of mosquitoes, and composition C4 did not land at all (Table 6).

[0108] Table 6. Repellent efficacy of five compositions against Aedes aegypti in warm body assay. Each composition was tested at three different doses applied on the attractant stimulus. The landing number during each control was used as a reference to normalize and calculate the percentage of repellency at the three different doses. As an index, a mean ± SD of 66 ± 8.5 mosquitoes landed on the unprotected attractant stimulus during the 2-minute control test period.

[0109] [Table 6]

[0110] All five compositions were able to repel more than 95% of mosquitoes when applied at 1% on the attractant stimulus (Table 7). A level of repellency of more than 90% started already at a concentration of 0.2% for composition C2 and 0.089% for composition B4 (Table 7). Even better, no mosquitoes landed on the attractant stimulus when lured with more than 0.04% of composition C4 (Table 7).

[0111] Table 7. Repellent efficacy of five compositions against Aedes aegypti in warm body assay. Each composition was tested at nine different doses applied on the attractant stimulus. The landing number during each control was used as a reference to normalize and calculate the percentage of repellency at all different doses. As an index, a mean ± SD of 59 ± 3.6 mosquitoes landed on the unprotected attractant stimulus during the 2-minute control test period.
