Method for integrated control of citrus fruit flies

Abstract

The invention discloses a method for integrated control of citrus fruit flies and belongs to fruit insect attack prevention methods. The citrus fruit fly control method is low in labor cost and can turn waste into wealth. According to the method, biological killing and physical cutting off of the insect source are combined; biological killing comprises the step of spraying a food trapping agent in the middle emergence period before massive coupling and oviposition, one third of plants in an orchard are sprayed with the food trapping agent, one third of the total area of each plant is sprayed with the food trapping agent, and spraying is conducted five times continuously; the food trapping agent is prepared from, by weight, 5% of Chinese rice wine, 5% of protolysate, 5% of vinegar and 85% of 90% crystal trichlorphon 500 times liquid; physical cutting off of the insect source comprises the steps of picking, maggoty fruit picking, and sinking into a biogas digester for insect killing. By the adoption of the method for integrated control of citrus fruit flies, the fruit-drop rate is reduced to 15% or less from the original 85% or more, and the control effect is quite remarkable.

Description

technical field [0001] The invention relates to a method for preventing and controlling citrus insect pests, in particular to a method for preventing and controlling citrus fruit fly, which belongs to the method for preventing and controlling fruit insect pests. Background technique [0002] The citrus fruit fly [Bactroceraminax (Enderlein)] belongs to Diptera, Tephritidae. Also known as orange eating fly, citrus fruit fly. The victimized fruit is called "maggot fruit" and "maggot orange". Bacteralis citrus can cause a large number of citrus fruit drop, the worst case reaches more than 90%, or even no harvest; it is one of the pests that do great harm to the citrus industry. [0003] The female adults of Bactrocera citrus use a needle-like ovipositor to pierce under the fruit skin to lay eggs. The damaged fruit will turn yellow when it is not ripe, and then turn green in the yellow. Because the adults have strong flying ability and the larvae hide in the fruit, it is diff...

AI Technical Summary

Problems solved by technology

At present, food traps for Bactrocera citrus mainly include sweet and sour wine mixture and hydrolyzed protein, but the attracting effects of these two types of drugs are not ideal enough to achieve the purpose of pest control

In addition, physical methods to isolate insect sources mainly use deep burial, scalding, incineration, exposure to the sun, etc., which not only have defects such as troublesome operation and high labor costs, but also cannot realize waste utilization and turn waste into treasure, resulting in waste of resources
