Definitions

  • the present invention relates to insecticidal and acaricide formulations of particular interest in practice and application owing to their low environmental impact.
  • insects such as for example mosquitoes
  • chemical means such as Pyriproxyfen and Diflubenzuron (nitro-organic) (I.G.R. - Growth Regulator - juvenile antihormones, growth inhibitors), Temephos (a phosphoric ester which is about to be taken off the market), Triclorphon and Fenitrothion (phospho-organic), or biological means, essentially Bacillus thuringiensis .
  • the aim of the present invention is to provide an insecticidal and acaricide formulation which has a substantially negligible toxicity for animals and for man.
  • Another object of the present invention is to provide an insecticidal and acaricide formulation which is adapted for optimizing the use of known substances by utilizing any synergistic effects thereof.
  • Another object of the present invention is to provide an insecticidal and acaricide formulation which has a low cost, is relatively simple to provide in practice and safe in application.
  • This aim and these and other objects which will become better apparent hereinafter are achieved by the following insecticidal and acaricide formulation, characterized in that it comprises, in proportions which can vary from approximately 0% to approximately 100%, salicylic acid, optionally present as any derivative thereof, even in combination with appropriate solvents and essential oils, and in that the remainder of the composition, where necessary, is optionally constituted by at least one excipient.
  • the essential oils that are present in the formulation according to the invention comprise essential oil of Mentha piperita.
  • the essential oils comprise, in proportions which can vary from approximately 0% to approximately 100%, essential oil of Melaleuca alternifolia, known commercially as tree oil, lemon essential oil, camphor essential oil, patchouli essential oil, and oregano essential oil.
  • the derivatives of salicylic acid can be respective salts or esters thereof which can be hydrolyzed in water: the choice of one derivative with respect to the other or with respect to the pure substance is dictated solely by production- or use-related requirements. It should in fact be clarified that if the processing of certain substances entails problems of various kinds
  • Two main practical embodiments of the invention are possible: 1) a solution whose action affects, both on the surface and in depth, the liquid medium that contains the immature stages of the Diptera to be suppressed. 2) A solution whose action affects the liquid medium only on the surface and acts only when the larvae or pupae of Diptera try to breathe.
  • the first case is a very powerful shock action, which depending on the depth of the body of water to be treated can cause the death of the larvae of mosquitoes and also of other kinds of insect that are present, such as for example chironomids, which live on the bottom of the body of water in the mud.
  • the second case is instead a less swift action which, however, is equally effective over time and does not affect organisms that live in the liquid medium but suppresses only organisms that need to breathe atmospheric oxygen and therefore must travel to the surface.
  • Both preparations are completely harmless for fish, especially if Mentha piperita essential oil is used.
  • Examples of the first embodiment are the use of salicylic acid and/or acetylsalicylic acid dissolved in pure alcohol, with Mentha piperita essential oil.
  • the quantity of the various components can vary in relation to the surface, the volume to be treated and the effectiveness, in terms of shock strength, to be achieved (for example in sewers and dung-heaps).
  • An effective formulation which reaches deeply into the liquid medium can be constituted by 4% of an alcohol solution of ethyl alcohol and salicylic acid (1%), 0.01% of Mentha piperita essential oil and 95.99% water, added at the time of use.
  • the presence of the alcohol in proportions which can vary according to requirements, ensures the formation of an extremely thin film on the surface of the liquid and the formation of a larvicidal cloud within the liquid medium.
  • Examples of the second embodiment are the use of salicylic acid dissolved to saturation or near saturation in Mentha piperita essential oil.
  • This second embodiment is by far more usable on an environmental level, since its impact is much lower on fauna and flora at the dilutions given hereafter: a) 14 g of salicylic acid dissolved in 100 ml of Mentha piperita essential oil are sufficient to treat 150 square meters. This solution, upon use, must be diluted beforehand in at least 1-10 liters of water, shaken well and poured, or still better, atomized, onto the surface to be treated. This concentration yields 100% mortality of mosquito larvae and pupae in 1 hour. The concentration of salicylic acid in Mentha piperita essential oil is 0.14 g/ml. 1 ml of undiluted solution contains 40 drops. Thus, one drop contains approximately 0.0035 g of salicylic acid.
  • a more concentrated solution composed of 17 g of salicylic acid dissolved in 100 ml of Mentha piperita essential oil, to treat 150 square meters with a swifter larvae suppressing action.
  • the solution upon use, must be diluted beforehand in at least 1-10 liters of water, shaken well and poured or better still atomized onto the surface to be treated. This concentration yields 100% mortality of mosquito larvae and pupae in 1 hour.
  • the concentration of salicylic acid in Mentha piperita essential oil is 0.17 g/ml.
  • 1 ml of undiluted solution includes 40 drops. Thus, in this case, one drop contains approximately 0.00425 g of salicylic acid.
  • Solutions containing less than 14 g of salicylic acid/ 100 ml of Mentha piperita essential oil do not achieve 100% effectiveness on pupae.
  • the solution constituted by 13 g of salicylic acid dissolved in 100 ml of Mentha piperita essential oil achieves 100% larvae mortality already after 30 minutes but only 20% pupae mortality even after 1.3 hours.
  • the concentration of 0.13 g of salicylic acid/1 ml of Mentha piperita essential oil is insufficient to suppress all the immature stages of mosquitoes. Therefore, the amount of 0.00325 g of salicylic acid that is present in one drop of said solution is not sufficient for total suppression of these insects.
  • the Mentha piperita essential oil must be saturated, or near-saturated, with salicylic acid: at this point, the resulting mixture can be, at the time of use, suitably diluted beforehand in appropriate amounts of water.
  • salicylic acid derivatives is understood to reference derivatives such as for example salts or esters which can be hydrolyzed in water, obtained by reaction with acids and alcohols, since salicylic acid contains both the OH group and the COOH group, which thus can give rise to the corresponding esters.
  • esters obtained by reaction from the hydroxyl group with acetic acid acetylsalicylic acid
  • esters obtained by reaction of the carboxyl group with various alcohols, such as for example methyl ester, ethyl ester, propionyl ester, phenyl ester, menthyl ester, et cetera.
  • alcohol or non-alcohol concentrated extracts containing salicylic acid or correlated compounds such as Spirea ulmaria or bark of willow tree or other plants such as horsetail, nettle, Achillea, Gaultheria, primrose, plantain, spear grass rhizome, hyacinth, et cetera.
  • the insecticidal formulations can comprise, in addition to said salicylic acid, also acetylsalicylic acid or derivatives thereof.
  • natural oil references an oily extract of plants or herbs which, due to its characteristics of viscosity, density and thixotropy, is capable of forming on the surface of the water (or other liquid which cannot mix with it) a continuous and thin film.
  • This compound of course will be used preferably for formulations which also act on the surface of the water or of other liquids which host the larvae to be destroyed.
  • the active ingredients will be dissolved, in the chosen proportions, in suitable solvents, optionally with heat, for example: alcohols, such as for example ethyl alcohol, phenoxyethanol, glycerin; dimethyl sulfoxide; Tween 20; vegetable oils
  • oils used in the formulated compound as active ingredients can be dissolved therein or added as such when the preparation is used or can be added to the formulated compound in microencapsulated form.
  • ingredients thus mixed other additives (for example effervescent products and acidity correctors, such as bicarbonate) suitable for application in particular environments or conditions or applications, or other compatible substances which have a synergistic action or not.
  • additives for example effervescent products and acidity correctors, such as bicarbonate
  • composition can be active both within and on the surface of the liquid on which it may be dispersed.
  • the insecticidal formulations according to the present invention allow to kill all the developmental stages of mosquitoes; this entails that the treated area will not produce new mosquitoes until new eggs are laid. Therefore, if the formulations according to the invention are used first and then the adults are killed within 1-2 days, which is very easy with the most common adulticides currently commercially available, one achieves substantially complete elimination of mosquitoes from an area, and since these insects do not have a substantial flying range, one can expect a clearing performed in this manner to solve rather well, with reasonable effectiveness, the problem of mosquitoes in a given area.
  • salicylic acid with essential oil can be considered an effective contact insecticide (which can also be formulated in/with microencapsulated form) against terrestrial insects (e.g., larvae of phlebotomes, culicoids, infestants, et cetera) or parasites (e.g.
  • Pediculus or Pthirus or an effective acaricide against ectoparasitic mites (in which it can reduce the ability to lay eggs, such as for example in ticks), such as for example Sarcoptes scabiei, a causal agent of scabies, or Demodex, and can be formulated differently according to the intended use.
  • Formulations comprising salicylic acid with essential oil further have an effective antibacterial action in liquids and in soil.
  • the insecticidal formulations according to the invention are useful for combating not only mosquitoes but also other insects which occupy a similar habitat or have a similar development cycle (in particular those with a development stage which takes place in water), such as for example larvae of the Diptera chironomids, chaoborids, dixids, et cetera.
  • the formulation (salicylic acid and Mentha piperita essential oil) will be isolated inside a containment receptacle of a closure of an appropriate bottle: once squeezed, the receptacle will open toward the inside of the bottle (at the time of use) and the solution will thus be poured into water.
  • the amount of water shall be determined in relation to the toxicity (and therefore the dilution to be obtained) and to the surface to be treated. This does not change what was stated earlier, that quantity of 14-17 g of salicylic acid and 100 ml of Mentha piperita essential oil is preferably used for 150 m 2 .
