Trapping and killing method for blueberry fruit flies and trapping and killing equipment

Abstract

The invention relates to the technical field of blueberry planting, and discloses a trapping and killing method for blueberry fruit flies, which comprises the following steps: S1, taking blueberries, and crushing the blueberries to obtain blueberry juice; S2, mixing white granulated sugar with the blueberry juice, and performing stirring and dissolving, wherein the mass ratio of the white granulated sugar to the blueberries is 0.03-0.1; S3, fermenting the dissolved liquid for 20-30 days, wherein stirring is conducted once after the dissolved liquid makes contact with air every 5-7 days in the fermentation process, and sealed fermentation is conducted in other time; S4, dissolving brown sugar and C4H8Cl3O4P crystals in the fermented liquid obtained in the S3, conducting full stirring for dissolution to obtain a trapping and killing liquid, wherein the dosage of the brown sugar in each liter of the fermented liquid is 50-100 g, and the dosage of the C4H8Cl3O4P crystals in each liter of the fermented liquid is 1.5-2.5 g; and S5, putting the prepared trapping and killing liquid into containers with openings, and hanging the containers in a blueberry field, wherein the height of the containers from the ground is 0.8-1.2 m, and 10-20 containers are evenly placed per mu. The fruit flies can be effectively prevented and controlled by using the trapping and killing method.

Description

technical field [0001] The invention relates to the technical field of blueberry planting, in particular to a method for trapping and killing blueberry fruit flies and a trapping and killing device thereof. Background technique [0002] The scientific name of blueberry is lingonberry, which belongs to the plant of the genus Vaccinium in the Ericaceae family. Flavonoid nutrition and health ingredients, the content of anthocyanins in the fruit is as high as 150 mg / 100 g of fresh fruit, which is several times or even dozens of times that of apples and grapes. Blueberry anthocyanins, as a natural nutritional and health-care ingredient, have obvious protective effects on human eyes, brain, liver, urinary and digestive systems. Therefore, as an emerging small fruit, blueberry is loved by consumers, has a large market demand, high price and broad development prospects. [0003] Blueberry Drosophila is a global quarantine pest. Its adults lay eggs under the skin of nearly mature b...
