Green oriental fruit moth prevention and control method

Abstract

The invention relates to a green oriental fruit moth prevention and control method, belongs to the field of insect prevention, and aims to overcome the current shortcoming that a large amount of chemical pesticide product is required to be sprayed to kill oriental fruit moths greatly harmful for fruit trees but human health is jeopardized by pesticides remaining in fruits. The method comprises the following steps of adding juice and a sugar and vinegar solution into carbonized fruit branches for air-drying, placing the air-dried fruit branches into an insect culture medium to culture oriental fruit moths, spraying cis-8-dodecenyl-1-acetate, taking the fruit branches out of the insect culture medium, adding a mixed solution prepared from fructus cnidii, stemona and frankincense for impregnation, air-drying the fruit branches, supporting yellow phosphor, and spraying the yellow phosphor onto the surfaces of the fruit branches. According to the method, the yellow phosphor is used for trapping and killing adult oriental fruit moths to reduce the using amount of chemical pesticides, control the damage degree of the chemical pesticides and fulfill the aims of timely and effectively destroying oriental fruit moths and controlling pesticide residuals from the source.

Description

technical field [0001] The invention relates to a green method for preventing and controlling the small pear borer, belonging to the field of insect control. Background technique [0002] The small pear borer is a kind of insect of the genus small borer in the family Toriidae of Lepidoptera. Distributed in Northeast, North China, Northwest and other places. Hosts include pears, apricots, cherries, peaches, pears and other plants. Among them, pears suffer the most. The larvae are harmful to the fruit. Before the fruit is bored, they often spin silk on the fruit surface and form a net. They live under the net and start to eat the fruit skin and eat into the fruit. The early fruit hole is black, and insect feces are discharged after a few days. Fruits with large bean grains are very easy to fall off in large quantities, and the damaged fruit will flow out a large amount of water bead-shaped pectin drops in the fruit-entry hole later. After entering the fruit, the nuts will ...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: in view of the fact that the small pear borer is very harmful to fruit trees at present, it is necessary to spray a large amount of chemical pesticide products to eliminate it, and at the same time, the pesticide will remain in the fruit and endanger human health, and a green control pear worm is provided. The method of the small borer, the method is to add the charred fruit tree branch into fruit tree juice, sweet and sour liquid, put it into the insect culture medium after air-drying, cultivate the small pear borer, and spray cis-8-dodecen-1-yl acetate , the fruit tree branches are taken out from the insect culture medium, soaked in the mixed solution made of A. chinensis, Libu and frankincense, and then loaded with yellow fluorescent powder and sprayed on the surface of the fruit tree branches after air-drying. This method uses yellow fluorescent powder to trap and kill the small pear borer adults, to reduce the amount of chemical pesticides used, control the degree of harm, and achieve the goal of timely and effectively eradicating small pear borer moths and controlling pesticide residues from the source
