Description
Technical Field
The present disclosure relates to a surfactant composition for controlling or controlling insects and methods of use thereof.
Background
Cockroaches are omnivorous insects with hundreds of millions of years of evolution history, which are highly productive and harbor bacteria on themselves, and are therefore widely recognized as a pest. Ants may harm crops and protect pests, for example, solenopsis invicta may bite with big jaws and secrete formic acid (formic acid) from the abdomen end to stimulate the bite wound, resulting in red swelling and pain of affected parts. Longicorn is a coleopteran insect whose larvae feed under the bark and, after the age increases, dig into and eat the wood, causing decay of the woods and wooden building, thus causing harm to the human living environment. The scarab beetles are the general name of insects of the family scarab beetle, and adults eat tender buds, new leaves and flowers of fruit trees, which cause economic losses of planted or recuperated flowers, fruit trees and crops.
In addition, mosquitoes transmit diseases (such as dengue fever, malaria, yellow fever, zkarst virus, filariasis, japanese encephalitis, west nile virus, chikungunya fever, etc.) from one host to another during ingestion, so about 7 million people are infected with the mosquitoes each year, and 1 person per 17 people die of the diseases transmitted by the mosquitoes, so mosquitoes are rated as one of the most dangerous animals worldwide. Wasps wake up from hibernation in spring, often bite people around their nest, and because their venom can trigger the nervous system of the person being bitten, skin allergic reactions such as swelling, pain and itching of affected parts are caused. Fleas are small, wing-free and jumping parasitic insects, and parasitic on the human body often cause allergic dermatitis and biting dermatitis, so that human skin generates pimples with different sizes and difficult itching. Spiders are of the amputation phylum, not strictly insects, but a large number of spiders have poison glands, which may affect the health of humans, and a small number of spiders have a more fatal risk.
Secondly, the locust is an insect with considerable harm, and the locust clusters fly fast to cause damage to large-area crops, so that crop resources and grains are affected. Recent research published in Nature journal 584, p.584-588, 2020, states that the factor triggering locust bunching is known as the pheromone (pheomone) of 4-vinyl anisole "4-vinylanisole" (4 VA), and that only 4-5 locust bunches are required to produce and release 4VA, which specifically causes an alkalinity sensory response on the locust antenna, attracting surrounding locust bunches. Recent research publications in journal of scientific Advances (Science Advances, jan.23, 2019) indicate that, by chemical analysis, benzyl cyanide (PAN) can be detected in all tissues and fluids of the group locust, but is not present in the solitary locust, so the group locust reduces predation of birds by PAN and serves as an olfactory characteristic signal in locust defense.
It is known that insects may have many effects on human life safety, food resources or living environment, but conventional chemical pesticides or pesticides and other harmful substances are widely applied to insects in various places for a long time, and some insects have been resistant to the harmful substances, so that the effects after application are greatly reduced. In addition, conventional chemical pesticides or insecticides often contain a large amount of volatile chemicals/organic solvents for rapid contact with insect surfaces, are prone to environmental pollution, and may also be hazardous to human and poultry health, and are therefore difficult and impossible to apply in large amounts to insects living or flying in groups.
Accordingly, in order to solve the above problems, there is a need to develop a surfactant composition for controlling or preventing insects and a method of using the same, so as to eliminate or alleviate the above problems.
Disclosure of Invention
In view of this, the present disclosure proposes a surfactant composition for controlling or controlling insects, which may be free of toxic substances, free of volatile chemical/organic solvents, free of any fluorine-, silicon-or phosphorus-based compounds or free of any aromatic compounds, or environmentally friendly and human and animal safe, and has a broad spectrum of properties against harmful insects.
To achieve the above object, according to one aspect of the present disclosure, there is provided a surfactant composition for controlling or preventing insects, comprising 0.01 to 5 weight percent of alkyl sulfosuccinate, 0.01 to 1 weight percent of humectant, and the balance being water. Here, the water used is not particularly limited, and is preferably purified water, distilled water, deionized water, or ultrapure water.
In the surfactant composition of the present disclosure, the alkyl sulfosuccinate may be a mono-alkyl sulfosuccinate, a di-alkyl sulfosuccinate, a poly-alkyl sulfosuccinate, or a combination thereof, wherein the mono-alkyl sulfosuccinate may have from 1 to 18 carbon chain alkyl groups, preferably from 4 to 18 carbon chain alkyl groups, more preferably from 4 to 12 carbon chain alkyl groups, most preferably from 6 to 8 carbon chain alkyl groups; the dialkyl sulfosuccinates may have two identical or different 1 to 18 carbon chain alkyl groups, preferably 4 to 18 carbon chain alkyl groups, more preferably 4 to 12 carbon chain alkyl groups, most preferably 6 to 8 carbon chain alkyl groups; and the polyalkylsulfosuccinate may have a plurality of identical or different 1 to 18 carbon chain alkyl groups, preferably 4 to 18 carbon chain alkyl groups, more preferably 4 to 12 carbon chain alkyl groups, and most preferably 6 to 8 carbon chain alkyl groups, but the disclosure is not limited thereto.
In the surfactant composition of the present disclosure, the alkyl sulfosuccinate may be an alkyl sulfosuccinate having the following chemical formula:
wherein R1 and R2 may be an alkyl group, respectively, but the disclosure is not limited thereto. Further, R1 and R2 may each be 1 to 18 carbon chain alkyl groups, preferably 4 to 18 carbon chain alkyl groups, more preferably 4 to 12 carbon chain alkyl groups, and most preferably 6 to 8 carbon chain alkyl groups, but the present disclosure is not limited thereto. Furthermore, R1 and R2 may be the same or different alkyl groups, and are preferably the same alkyl groups.
In the surfactant composition of the present disclosure, the humectant may be an alkyl monol, an alkyl diol, an alkyl polyol, or a combination thereof, wherein the alkyl group may be 1 to 18 carbon chain alkyl groups, preferably 4 to 18 carbon chain alkyl groups, more preferably 4 to 12 carbon chain alkyl groups, and most preferably 6 to 8 carbon chain alkyl groups, but the present disclosure is not limited thereto.
In the surfactant composition of the present disclosure, the surfactant composition may be free of any volatile compound organic solvent, free of any fluorine, silicon or phosphorus-based compound, free of any aromatic compound or free of conventional pesticides or insecticides, but the present disclosure is not limited thereto.
According to another aspect of the present disclosure, there is provided a method of using an insect surfactant composition for controlling or preventing, comprising the steps of: (a) formulating a surfactant composition as described above; and (b) applying the surfactant composition obtained in (a) to an insect. Through the excellent solvency of the surfactant compositions of the present disclosure, the transmission of volatile compounds pheromones of insects can be eliminated and blocked to reduce or prevent insect population or swarm flight.
In addition, since most insects breathe with the tracheal system in the body, the tracheal system is spread throughout the body and vented to the atmosphere by the air valve (air valve), through which air is diffused into the trachea (trachia), the bronchi and the micro-bronchi (trachele) branching stepwise, and finally into the tissue cells. Thus, if the opening and closing of the air valve on the insect body can be affected, the respiratory system of the insect can be affected. If the insect respiratory system can be affected, the insect's flight can be controlled and even its survival can be affected. Thus, insects may also be moistened by applying the surfactant composition of the present disclosure to the insects, causing the insects to breathe hard or increase in weight, to reduce their mobility or flying ability.
In the method of the present disclosure, the insect may be any insect having an air hole, an air pipe, an air bag, or a combination thereof forming a respiratory system, for example, may be a locust, a fly, a longhorn beetle, a spider, a wasp, a winged insect, a fly, a cockroach, or a pillworm (a tide), etc., but the present disclosure is not limited thereto.
In the methods of the present disclosure, the insects may be any crawling or flying insects, either static or dynamic, but the present disclosure is not limited thereto.
In the method of the present disclosure, the insects may be any insects that are scattered or colonised, but the present disclosure is not limited thereto.
In the methods of the present disclosure, wherein such methods may be applied to prevent or contain the aforementioned insect population or swarm fly, the present disclosure is not limited thereto.
In the methods of the present disclosure, wherein such methods are useful for controlling or controlling eggs, larvae, or adults of insects, the disclosure is not limited thereto.
In the methods of the present disclosure, the aforementioned surfactant compositions may be applied directly to the aforementioned insects using spray, foam, aerosol, spread, cover, pour-on, or combinations thereof, but the present disclosure is not limited thereto.
Other objects, advantages and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the drawings.
