Fruit fly attractant, and preparation method and using method thereof

Abstract

The invention discloses a fruit fly attractant, and a preparation method and a using method thereof. The preparation method comprises the following steps: taking disease-and-pest-free ripe fresh leaves of strong grown red raspberry, adding the leaves into water, boiling the water, and cooling the water after the water and the leaves are boiled for 10-12 min in order to prepare a solvent for lateruse; and uniformly mixing brown sugar, vinegar, Chinese liquor and the solvent in proportion to prepare the attractant. The prepared fruit fly attractant is sub-packaged in 1-2 L small barrels; and after the attractant is prepared, the small barrels are immediately hung on orchard supports or branches, have a distance of 0.5-0.7 m to the ground, and is placed in a ventilating and direct sunlight-avoiding place, and 1-2 small barrels are hung every 10-12 m. The components of the prepared attractant are edible substances, so the attractant has the advantages of no side effects, safety, effectiveness, no pollution to the environment, no influences on the quality of red berry fruits, and realization of quality guaranteeing, quality ensuring, high yield and stable production of the orchard.

Description

technical field [0001] The invention relates to the field of pest control, in particular to a fruit fly attractant and its preparation method and application method. Background technique [0002] As people pay more attention to dietary health and safety, green and organic fruits are more and more respected by the public. In addition to harming raspberries, spotted wing Drosophila can also harm multiple fruits such as cherries, grapes, raspberries, blueberries, and blackberries, seriously affecting the quality of fruits and the economic income of fruit farmers. [0003] The methods of preventing and controlling fruit flies currently used in production mainly include chemical control and physical control, and the effects are different. At present, the main chemical control is cherry fruit fly, which is fast and effective, but at the same time, the fruit is polluted by chemical agents, and the safety problem is also very prominent, such as patent 201410222524.5, which uses alk...

Problems solved by technology

At present, the main chemical control is cherry fruit fly, which is fast and effective, but at the same time, the fruit is polluted by chemical agents, and the safety problem is also very prominent, such as patent 201410222524.5, which uses alkaloids, attractant substances, preservatives, auxiliary agents, although The purpose of preventing and controlling fruit flies is achieved, but preservatives, alkaloids and auxiliary agents will affect the quality of the fruit, and are not easy to degrade and pollute the environment; while patent 201510416263.5 uses fruit and vegetable food, beverages, yeast, vinegar, sweeteners, etc. Many green raw materials, but it also uses pesticides and other hormones that pollute the fruit and the environment

Although physical prevention has been the main research direction in China in recent years, mainly focusing on physical and biochemical prevention and development of biological pesticides, the existing physical prevention effects are still relatively poor.
