Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insect attractant, in particular to a mosquito and fly bait and a preparation method thereof. BACKGROUND

[0002] Mosquitoes and flies spread diseases, in order to drive and kill mosquitoes and flies, people have developed a variety of products, such as the currently widely used various insecticides, mosquito and fly repellent, mosquito incense, electric mosquito killer, etc., but in use, it is found that the various drive and kill mosquitoes and flies products always have many shortcomings; such as insecticides have good killing effect on mosquitoes and flies, but have some side effects on the human body and the environment, and long-term use of insecticides, mosquitoes and flies are prone to drug resistance; the common effect of various mosquito and fly repellents, mosquito incense, etc. is to drive mosquitoes, which is a temporary solution; and various indoor and outdoor electric mosquito and fly killers use light sources to capture mosquitoes and flies, which has poor attraction and unsatisfactory effect.

[0003] A Chinese patent application with the application number 200410060897.3 discloses an additive for trapping flies and mosquitoes, and a firefly device added with the additive. It is made by mixing raw materials of grain 500-1000, wine starter 0.1-4, root mold 0.1-4, spices 0.1-1, and water 2-20, and then fermenting. It has the advantages of safety and health, no harm, no pollution, long storage time, and convenient use. However, the main raw materials of the fly trapping agent produced by the patent are grain, wine starter, root mold, and spices, which are fermented to produce a certain amount of alcohol. The alcohol has a pungent smell, which is not the smell that mosquitoes and flies like, so it is not conducive to trapping mosquitoes and flies.

[0004] A Chinese patent application with the application number 201410172163.8 discloses a fly attractant and a preparation method thereof. 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, which have no environmental pollution and no toxic side effects. The fly attractant provided by the present application overcomes the shortcomings of traditional food-grade attractants, can long-term and efficiently attract flies, has good attraction effect and long duration, and also overcomes the shortcomings of traditional chemical attractants, significantly improves the attraction effect of the attractant on saprophagous and omnivorous flies without adding skatole. SUMMARY

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

[0006] The purpose of the present application is achieved by the following technical solution: a mosquito fly bait comprising the following raw materials by weight:

[0007]

[0008]

[0009] The mosquito fly bait of the present application can attract mosquitoes and flies by using brown sugar preferred by flies, adding starch and yeast extract, producing a sour taste after fermentation, odor attraction of skatole, and volatile assistance of ethanol. Fresh fish skin can attract mosquitoes and flies by odor and provide a carrier, increasing the adhesion area of the bait, better attracting mosquitoes and flies, and potassium sorbate can prevent long-term mold and odor. The obtained mosquito fly bait has strong attraction to mosquitoes and flies, and when mosquitoes and flies smell the odor of the mosquito fly bait, they will directly fly to the mosquito fly bait to feed, without environmental pollution and toxic side effects, and can long-term and efficiently attract mosquitoes and flies, with good attraction effect and long duration.

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

[0011]

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

[0013]

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

[0015] Preferably, the mosquito fly bait further comprises palmitic acid 1.5-2.5 parts. Palmitic acid can provide a special aroma and taste in the mosquito fly bait, which may have an attractive effect on mosquitoes and flies.

[0016] Preferably, the mosquito fly bait further comprises xanthan gum 0.4-0.8 parts. Xanthan gum can increase the stickiness and volatility of the bait, making the odor of the bait more easily spread and attract mosquitoes and flies, thereby improving the trapping effect. At the same time, xanthan gum can also help the bait maintain appropriate viscosity, facilitating the contact and adhesion of mosquitoes and flies.

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

[0018] Preferably, the mosquito fly bait further comprises 0.5-1.5 parts of Muscimyl. Muscimyl (cis-9-tricosene) has strong attraction to mosquitoes and flies.

[0019] Preferably, the mosquito fly bait further comprises 0.1-0.5 parts of deltamethrin and 0.1-0.5 parts of piperonyl butoxide. Delthamethrin has 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 application is achieved by the following technical solution: a preparation method of a mosquito fly bait, wherein brown sugar, starch and yeast extract are mixed and fermented at room temperature for 3 days to obtain a fermentation product; fresh fish skin is cut into 1cm*1cm, the fermentation product and the remaining materials are added and stirred uniformly to prepare the mosquito fly bait.

[0021] The mosquito fly bait of the present application has the following advantages: the mosquito fly bait of the present application uses brown sugar which is preferred by flies, and adds starch and yeast extract, and produces sour taste after fermentation, which can attract mosquitoes and flies, skatole can attract mosquitoes and flies by smell, ethanol can assist volatilization, fresh fish skin can attract mosquitoes and flies by smell and provide a carrier, which increases the adhesion area of the bait, so that mosquitoes and flies can be better attracted, potassium sorbate can prevent long-term mold and odor, the obtained mosquito fly bait has strong attraction to mosquitoes and flies, when mosquitoes and flies smell the smell of the mosquito fly bait, they will directly fly to the mosquito fly bait to feed, and the mosquito fly bait has no environmental pollution and no toxic side effects, can long-term and efficiently attract mosquitoes and flies, has good attraction effect and long duration.
