Efficient low-cost drosophila melanogaster attractant and preparation method thereof

Abstract

The invention discloses an efficient low-cost drosophila melanogaster attractant and a preparation method thereof. The efficient low-cost drosophila melanogaster attractant is prepared from, by weight, 10-30 parts of fruit fermentation liquor, 70-90 parts of clear water, 0.1-0.5 part of alkaloid and 0.1-0.5 part of sodium benzoate. The preparation method comprises the following steps of (1) crushing fruits, putting the crushed fruits into a fermentation container, performing natural fermentation at 25-30 DEG C for 36-48h, and then performing extrusion and filtration so as to obtain fruit fermentation liquid; (2) adding clear water into the fruit fermentation liquid obtained in the step (1) for dilution to obtain a diluent; and (3) adding alkaloid and sodium benzoate into the diluent obtained in the step (2), and uniformly stirring to obtain the drosophila melanogaster attractant. The attractant provided by the invention has the characteristics of strong attraction capability, long validity period, organic environmental protection, low cost and simple preparation method.

Description

technical field [0001] The invention relates to a fruit fly trap and a production method thereof, in particular to a high-efficiency and low-cost fruit fly trap and a production method thereof. Background technique [0002] Drosophila (drosophilid or drosophilidfly), sometimes called fruitfly, is an insect belonging to the order Diptera, Brachycera, Drosophilidae, and the genus Drosophila. [0003] As a common pest in agriculture, fruit flies often need to be killed during agricultural production. The most adopted method at present is the method of pesticide killing, which has quick effect and long-lasting effect. However, there are many problems in the killing of pesticides. First of all, manual spraying is required, which is time-consuming and labor-intensive. At the same time, pesticides have become a major hazard to modern human health. Fruits and vegetables that are not suitable for washing and direct consumption. Therefore, reducing the use of pesticides has become ...

AI Technical Summary

Problems solved by technology

Although fruit fly traps have been widely studied, there are still many problems in the current common fruit fly traps, such as patent CN201510416263.5 which discloses a fruit fly trap and its preparation method. and vegetables and other leftovers, the mixture of vinegar and sweetener is used as an attractant, and insecticide is added therein as an insecticidal component to trap and kill fruit flies; however, it still does not solve the problem of pesticide residues. The problem is that the pesticides are still harmful components that are harmful to health, and in this technology, its induction ability is insufficient. The applicant found that the reason is that the fermented products are made of fruits, food processing waste and vegetables. Fermented raw materials, and due to defects in the preparation process and ratio, the fermented product obtained is not very attractive to fruit flies, and even contains ingredients to repel fruit flies, although it adds sweeteners and vinegar to the formula , however, the applicant found that its ability to attract fruit flies is still limited

And although the patent CN201410222524.5 discloses a fruit fly trap and its preparation method, and specifically discloses the use of alkaloids instead of traditional insecticides, which reduces environmental pollution and human health hazards, but its The specific attractant substance is not disclosed, and the attracting ability of fruit flies is unknown
