Citrus fruit fly adult trapping and killing agent and using method thereof

Abstract

The invention discloses a citrus fruit fly adult trapping and killing agent. 100 ml of the trapping and killing agent is prepared from 5-25 g of brown sugar, 3-8 ml of acetic acid, 1-5 ml of ethanol, 4-8 ml of ethyl acetate, 0.5-2.0 ml of D-limonene, 0.1-0.3 g of citric acid, 4-6 ml of citrus juice or 4-6 ml of orange juice or 1-3 ml of sweet orange flavored essential oil, 0.10-0.35 ml of 10% efficient cyhalothrin emulsion in water and the balance water. A using method of the citrus fruit fly adult trapping and killing agent comprises the following steps that a colorless transparent plastic bottle with the diameter of 55-75 mm is selected, an opening is formed in the positions, 80-120 mm away from the bottom, of the two walls of the bottle respectively through shearing, and the plastic pieces obtained through shearing are opened along the upper edges to cover the openings like eaves. When the citrus fruit fly adult trapping and killing agent is used, the agent is added into the transparent plastic bottle, and the transparent plastic bottle is hung at the shady and cool ventilated position of a citrus tree. The citrus fruit fly adult trapping and killing agent is convenient to use, low in cost, stale in control and extremely high in trapping and killing efficiency and is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of agricultural fruit trees, and more specifically relates to a trapping and killing agent for Bactrocera citrus adults and a method for using the same. Background technique [0002] Citrus fruit fly Bactroceraminax (Enderlein), commonly known as "citrus maggot", belongs to Diptera (Diptera) Tephritidae (Tephritidae), is a destructive pest of citrus, and is a plant quarantine pest at home and abroad. Bactrocera citrus mainly affects citrus plants such as lime, lemon, grapefruit, citron, sweet orange, bergamot, tangerine and grapefruit. The range of harm is particularly wide, including most of the citrus producing areas in my country. [0003] There is one generation of Bactrocera citrus per year, which emerges from April to May, and then flies into the woods near the citrus orchard to feed and supplement nutrition, and then flies into the citrus orchard from June to July to lay eggs on citrus. Hatch from A...

Problems solved by technology

Chinese patent document 201010196027.4 discloses a Bactrocera citrus protein bait and its preparation and use method, which is prepared from 10-20% of brewer's yeast hydrolyzate, 0.2-1% of ammonium acetate, 5% of brown sugar and 5% of orange juice, but The preparation of beer yeast hydrolyzate is cumbersome and requires a series of steps such as inactivation, filtration, heating and concentration, proteolysis, and termination reaction, and the operation is cumbersome

This method coats the solid attractant on the inner wall above the opening of the transparent plastic bottle. Although it has a certain luring effect on B. Insecticide 0.25~0.3wt% trichlorfon is placed at the bottom of the bottle, and the separation of its attractant and insecticide is not conducive to the trapping and killing of Bactrocera citrus

This method hangs the plastic bottle at a height of 1.3-1.8m from the ground in the citrus orchard. In fact, some citrus trees are not 1.3m high enough, and hanging at a height of 1.3-1.8m will have an impact on the overall trapping and killing effect of Bactrocera citrus.

In addition, the length of the rectangular mouth in the opening of the transparent plastic bottle used in this method is 20-25 mm, and the opening is slightly smaller, which is not conducive to the entry of Bactrocera citrus.

The above methods can trap Bactrocera citrus to a certain extent, but the trapping effect is not ideal, and some production methods are cumbersome, which is not conducive to the use in production practice
