Fruit fly food source attractant and preparation method thereof

Abstract

The invention relates to fruit fly food source attractant. The fruit fly food source attractant is characterized in that the essential component of the attractant adopts bananas; the mass percent of the bananas to the attractant is 80 to 99 percent; preferably, the mass ratio of bananas to yeast to casein peptone is 8-10:0.01-0.03:0.9-1.1; bananas, yeast and casein peptone are mixed according to the mass ratio of 8-10:0.01-0.03:0.9-1.1, appropriate water is added to the bananas, yeast and casein, then soft material is obtained after stirring, sifting pelletization is performed so as to ensure that the granular sizes are uniform, the granular size reaches 16 to 18 meshes, the granules are pressed into flake through a pelleting press, and then finished products are obtained after drying through an oven. The fruit fly food source attractant has the characteristics that the attractant is safe and reliable to use, nonhazardous and pollution-free, and has a good attractive effect on fruit flies, and the persistent period of the attractive effect is long, and the fruit fly food source attractant is particularly applicable to strategies of fly prevention of Chinese bayberry.

Description

Technical field [0001] The invention belongs to the field of pest control, and specifically relates to a fruit fly food attractant and a preparation method thereof. Background technique [0002] Bayberry is native to Zhejiang Province, my country, in East China And Hunan, Guangdong , Guangxi, Guizhou It is distributed in other regions and is an important economic product of our country. Drosophila, as an important pest that harms bayberry fruit trees, causes huge losses to bayberry fruits. At present, the control of fruit flies basically completely relies on chemical pesticides, except for the early weeding of the bayberry gardens, the sorting out of the physiological fruit drop before the bayberry maturity and the rotted fruit during the mature harvest period. However, the use of chemical agents for prevention and control has poisoned fruit flies, but also poisoned natural enemies. At the same time, there are still pesticide residues, which poses serious environmental and food...

AI Technical Summary

Problems solved by technology

Compared with the traditional chemical control, this attractant has been greatly improved in terms of environmental friendliness, but it still has a small amount of toxic components in its composition

As red bayberries are gradually being exported to foreign countries, the problem of pesticide residues caused by the use of chemical pesticides is difficult to overcome the green trade barriers in exports
