Description

Technical Field

[0001] The invention relates to the technical field of insect attractants, and in particular to a mosquito and fly bait and a preparation method thereof. Background Art

[0002] Mosquitoes and flies spread diseases. In order to repel and kill mosquitoes and flies, people have developed various products, such as various insecticides, mosquito repellents, fly medicines, mosquito coils, electric mosquito killers, etc., which are widely used on the market. However, it is found in use that the wide variety of products for repelling and killing mosquitoes and flies always have many shortcomings. For example, insecticides have a good killing effect on mosquitoes and flies, but have some side effects that are harmful to the human body and the environment, and mosquitoes and flies are prone to develop drug resistance after long-term use of insecticides. The common effect of various mosquito repellents, fly medicines, mosquito coils, etc. is to repel mosquitoes, which is a temporary solution but not a fundamental solution. Various electric mosquito and fly killers used indoors and outdoors use light sources to trap mosquitoes and flies, which have poor temptation and unsatisfactory effects.

[0003] The Chinese invention patent with application number 200410060897.3 discloses an additive for trapping flies and mosquitoes, and a fly trap containing the additive. The additive is prepared by mixing 500-1000 parts of grain, 0.1-4 parts of distiller's yeast, 0.1-4 parts of root mold, 0.1-1 parts of spices, and 2-20 parts of water, and then fermenting the mixture. The additive has the advantages of being safe, hygienic, harmless, pollution-free, having a long storage time, and being easy to use. However, the fly trap produced in the patent is prepared by fermenting grain, distiller's yeast, root mold, and spices. The grain produces a certain amount of alcohol after fermentation by distiller's yeast. The alcohol has a pungent smell, which is not a smell that flies like, and is therefore not conducive to trapping flies.

[0004] The Chinese invention patent with application number 201410172163.8 discloses a fly attractant and also discloses its preparation method. The fly attractant is made of component A, component B, component C and component D, and the weight ratio of component A, component B, component C and component D is: component A: component B: component C: component D = 180: (10-500): (10-300): (0-10). The raw materials used in the fly attractant are all food-grade raw materials, without environmental pollution and no toxic side effects. The fly attractant provided by the present invention overcomes the shortcomings of traditional food-grade attractants, can attract flies for a long time and efficiently, has good attracting effect and long duration. The present invention also overcomes the shortcomings of traditional chemical attractants, and significantly improves the attracting effect of the attractant on saprophagous and omnivorous flies without adding skatole. However, the patent uses agar as a carrier, and only the upper surface can attract flies, and the effect is poor. Summary of the invention

[0005] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a mosquito and fly bait and a preparation method thereof.

[0006] The object of the present invention is achieved through the following technical solution: a mosquito and fly bait, the mosquito and fly bait comprises the following raw materials in parts by weight:

[0007]

[0008]

[0009] The mosquito and fly bait of the present invention adopts brown sugar, which is preferred by flies, and adds starch and yeast extract. After fermentation, a sour smell is generated, which can attract mosquitoes and flies. Skatole can attract the smell, ethanol can assist in volatilization, and fresh fish skin can attract the smell and provide a carrier, thereby increasing the bait adhesion area and better luring the bait. Potassium sorbate can prevent rot and mildew. The obtained mosquito and fly bait has a strong attraction to mosquitoes and flies. When mosquitoes and flies smell the smell of the mosquito and fly bait, they will directly fly to the mosquito and fly bait to eat. The mosquito and fly bait has no environmental pollution, no toxic side effects, can attract mosquitoes and flies for a long time and efficiently, and has a good attraction effect and a long duration.

[0010] Preferably, the mosquito and fly bait comprises the following raw materials in parts by weight:

[0011]

[0012] More preferably, the mosquito and fly bait comprises the following raw materials in parts by weight:

[0013]

[0014] Preferably, the mosquito and fly bait also includes 1-3 parts of ethyl maltol. Ethyl maltol is a food flavor additive that can increase the attraction to mosquitoes and flies.

[0015] Preferably, the mosquito and fly bait also includes 1.5-2.5 parts of palmitic acid. Palmitic acid can provide a special aroma and taste in the mosquito and fly bait, and this characteristic may attract mosquitoes and flies.

[0016] Preferably, the mosquito and fly bait also includes 0.4-0.8 parts of xanthan gum. Xanthan gum can increase the viscosity and volatility of the bait, making the smell of the bait easier to emit and attract mosquitoes and flies, thereby improving the trapping effect. At the same time, xanthan gum can also help the bait maintain an appropriate viscosity, making it easier for mosquitoes and flies to contact and adhere.

[0017] Preferably, the mosquito and fly bait further comprises 0.6-1.0 parts of dipotassium hydrogen phosphate, which is used as a stabilizer.

[0018] Preferably, the mosquito and fly bait further comprises 0.5-1.5 parts of entebbene, which has a strong attraction to mosquitoes and flies.

[0019] Preferably, the mosquito and fly bait also includes 0.1-0.5 parts of deltamethrin and 0.1-0.5 parts of piperonyl butoxide. Deltamethrin has a good insecticidal effect on mosquitoes and flies. Piperonyl butoxide can be used as a synergist of deltamethrin to improve the insecticidal effect of the bait.

[0020] Another object of the present invention is achieved through the following technical scheme: a method for preparing mosquito and fly bait, comprising mixing brown sugar, starch and yeast extract and fermenting the mixture at room temperature for 3 days to obtain a fermented product; cutting raw fish skin into 1cm*1cm sizes, mixing the fermented product and the fermented products of other materials evenly to obtain a mosquito and fly bait.

[0021] The beneficial effects of the present invention are as follows: the mosquito and fly bait of the present invention adopts brown sugar, which is preferred by flies, and adds starch and yeast extract, so that a sour smell is generated after fermentation, which can attract mosquitoes and flies; skatole can attract by smell; ethanol can assist in volatilization; fresh fish skin can attract by smell and provide a carrier, so that the adhesion area of ​​the bait is increased, and mosquitoes and flies can be better attracted; potassium sorbate can prevent rot and mildew; the obtained mosquito and fly bait has a strong attraction to mosquitoes and flies; when mosquitoes and flies smell the smell of the mosquito and fly bait, they will directly fly to the mosquito and fly bait to eat; the mosquito and fly bait has no environmental pollution, no toxic side effects, can attract mosquitoes and flies for a long time and efficiently, and has a good attracting effect and a long duration.
