Slow release fruit fly attractant and application thereof

Abstract

The invention relates to a slow release fruit fly attractant and application thereof, belonging to the field of pest control. The slow release fruit fly attractant comprises the following main components in percentage by weight: 1-20% of carbohydrate, 5-40% of protein source materials, 0.5-20% of plant allelochemicals, 0.01-10% of toxic components, 0.5-5% of emulsifying agent, 1-15% of moisture regulator and 0.1-5% of preservative. By adding water to the components to 100% and fully and uniformly stirring, a semisolid ointment slow release attractant is obtained to be applicable to the prevention and treatment of fruit flies. The slow release attractant of the invention exists in a semisolid ointment state, can be directly scrawled in a fruit fly attracting bottle, can be mixed with waterfor local spraying, and has the characteristics of very convenient operation, male-female attraction, favorable attraction effect, long duration and safety for the crop.

Description

A slow-release attractant for fruit flies and its use technical field The invention belongs to the field of pest control, and in particular relates to a slow-release attractant for fruit flies and its application. Background technique Drosophila pests belong to the order Diptera and the family Drosophilidae, and are distributed worldwide. So far, there are more than 2,500 known species, which belong to 57 genera of Drosophila subfamily and Drosophila subfamily; So far, more than 180 species of 17 genera have been recorded in China. Drosophila melanogaster, Drosophila melanogaster, Drosophila takahashii and Drosophila imi are more common and widely distributed in various regions of the country. The adult fruit flies feed on plant sap, and it is the larvae that are most damaging. Adult female fruit flies burrow holes in the skin of fruits and vegetables and lay eggs. After the eggs hatch, their larvae grow rapidly and feed on the pulp. Soon, the ravaged fruit falls to the...

AI Technical Summary

Problems solved by technology

Drosophila can attack almost all vegetables and fruits, such as apples, peaches, pears, mangoes, bayberry, litchi, pomegranate, strawberries, grapes, citrus, loquats, peppers, various vegetables, edible fungi and other economic crops, and the damaged fruits are uneven , juice spillage and fruit drop, the yield will decrease, the quality will deteriorate, affecting fresh sales, storage, processing and commodity prices, thus causing serious economic losses

At present, the methods used to prevent and control fruit flies in China mainly include: 1. Chemical control. Because the larvae of fruit flies are generally in the fruit, coupled with factors such as strong flying ability of adults, strong fecundity, and easy generation of drug resistance, chemical pesticide control It is necessary to increase the dose or increase the concentration, and there are serious environmental and food safety hazards. At the same time, the labor intensity is high when the whole plant is sprayed into pieces, and the control effect is not ideal.

2. Artificial fruit bagging, this method not only affects the quality of the fruit, but also takes up a lot of labor and the cost is high

3. Add a certain amount of poison to the mixture of sweet and sour wine, and put it in a lure bottle to lure and kill. The problem with this method is that the lure effect is not ideal, the duration of the effect is not long, and the prevention and control of harm cannot be achieved.
