Description

Technical Field

[0001] The present invention relates to the technical field of biological pesticides, and particularly relates to a spinosad cockroach bait and a preparation method thereof. Background Art

[0002] Cockroaches are common household insects with strong reproductive ability and complex food intake varieties. When cockroaches eat, they eat, vomit, and excrete at the same time, resulting in food contamination and disease transmission. Therefore, the prevention and control of cockroaches cannot be relaxed. The insecticidal components of commercially available cockroach control drugs generally include imidacloprid, acephate, fipronil, hydramethylnon, chlorpyrifos, dinotefuran, pyrethroids, boric acid, and PFDNV insect virus, etc. A considerable number of varieties have developed resistance. To protect public health, it is imperative to develop new varieties of cockroach control agents.

[0003] The technical problems that need to be overcome by cockroach control agents are high efficiency and low toxicity, and they cannot cause unpleasant odors and high pesticide residues in the living room; at the same time, they need to have sufficient attraction to cockroaches, ensure an appropriate feeding rate, and ensure that there is enough dose of the active pharmaceutical ingredient to kill cockroaches after entering the cockroach body.

[0004] Spinosad, also known as spinosad, is a macrolide non-polluting and highly effective biological insecticide extracted from the fermentation broth of Saccharopolyspora spinosa. Because of its broad insecticidal spectrum, high insecticidal activity, biodegradability, and safety for beneficial insects and mammals compared with other pesticides, it has been gradually developed and used in the pesticide industry. However, when using it to prepare cockroach bait, due to its musty earthy smell, it is not liked by cockroaches. Therefore, it is crucial to develop a spinosad cockroach bait and a preparation method thereof that can attract cockroaches to eat spinosad. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects of the prior art, and provides a spinosad cockroach bait and a preparation method thereof, which are green, environmentally friendly, biodegradable, not easy to absorb moisture and cake, and can induce cockroaches to eat.

[0006] In order to achieve the above purpose, the technical solutions adopted by the present invention are as follows:

[0007] Technical Solution 1:

[0008] A spinosad cockroach bait includes spinosad, sugars, taste additives, flavors, and fillers; further, the sugar is preferably aspartame.

[0009] Further, a spinosad cockroach bait includes the following raw materials in percentage by content:

[0010]

[0011] Further, the taste additive includes one or more of talcum powder and mono- and diglycerol fatty acid esters; preferably, the taste additive is selected from talcum powder, mono- and diglycerol fatty acid esters or a combination thereof; more preferably, the taste additive is selected from the combination of talcum powder and mono- and diglycerol fatty acid esters, and the mass ratio of talcum powder to mono- and diglycerol fatty acid esters is 1525:1.

[0012] Further, the essence is a milk flavor essence.

[0013] Further, the filler is roasted soybean cake powder.

[0014] Further, a spinosad cockroach bait includes the following raw materials in percentage by weight:

[0015]

[0016] Technical solution two:

[0017] A preparation method of the spinosad cockroach bait includes the following steps:

[0018] Weigh each component in proportion, mix and stir evenly, then place it in an ultrafine air flow pulverizer for pulverization. After discharging, continue to stir until evenly mixed, and optionally sieve to obtain the spinosad cockroach bait.

[0019] Further, it is pulverized to a particle size less than or equal to 3 microns by an ultrafine air flow pulverizer.

[0020] Compared with the prior art, the beneficial effects obtained by the present invention are as follows:

[0021] The present invention uses spinosad as an effective drug component for killing cockroaches, which has a broad insecticidal spectrum, high insecticidal activity, and is degradable, and is safer for beneficial insects and mammals compared with other pesticides; the present invention uses aspartame instead of traditional sugars, making the cockroach bait not easy to absorb moisture and agglomerate.

[0022] Talcum powder and mono- and diglycerol fatty acid esters are mainly used as lubricants in the food and pharmaceutical fields. The present invention adds talcum powder to increase the smooth feeling of the cockroach bait in the mouth, and adds mono- and diglycerol fatty acid esters to improve its taste.

[0023] The present invention makes the cockroach bait have a strong milk fragrance by using a milk flavor essence, which can cover up the stale earthy smell of spinosad itself. The present invention uses roasted soybean cake as a filler, and the fragrance it emits is liked by most animals, which can improve the feeding rate of cockroaches. Specific embodiments
