Comprehensive citrus fruit fly control method based on PUSH-PULL strategy

Abstract

Provided is a comprehensive citrus fruit fly control method based on a PUSH-PULL strategy. The method comprises the control measures of two links of the adult stage and the larval stage; in the adult state, adults are rejected from entering a citrus orchard to lay eggs by adopts the Push-Pull strategy, and the adults are killed outside the citrus orchard; in the larval stage, wormed fruits (maggot fruits) are removed, picked up and treated for killing insects. The method particularly comprises the steps that in the adult emergence and egg laying period, repellent is sprayed in the citrus orchard, an odor barrier is set up for avoiding the adults, the adults are blocked from entering the citrus orchard to lay eggs, and the adults are induced by food attractant to gather around the citrus orchard to be killed; for the larval stage, in the stage that the wormed fruits are yellowed before the fruits are ripe, the wormed fruits yellowed in advance in trees are removed, dropped fruits on the ground are picked up ad collected, centralized treatment is effectively conducted, and larva are killed. The method is green and environmentally friendly, the raw materials are easy to obtain, the cost is low, the control effect is stable, the killing efficiency is high, the wormed fruit treatment method is easy and convenient to implement and is not limited by environmental conditions, and damage of fruit flies to citruses is effectively controlled.

Description

technical field [0001] The invention relates to a method for comprehensive prevention and control of citrus fruit flies based on a PUSH-PULL strategy. Background technique [0002] Bactrocera citrus Bactrocera minax (Enderlein), Bactrocera citrus Tetradacus tsuneonis , Bactrocera citrus Bactrocera dorsalis (Hendel) all belong to Diptera (Diptera) Tephritidae (Tephritidae), are destructive pests of citrus. Among them, two species of Bactrocera medulla have one generation per year and are specialized in harming citrus fruits. Bactrocera dorsalis has multiple generations per year and can harm more than 250 kinds of fruit trees and vegetable fruits including citrus. The adults of these species of fruit flies lay eggs in the citrus fruit, and the larvae bore into the citrus fruit and feed on the pulp of the tangerine petals, causing the fruit to fall off and rot early before it is ripe, and lose its edible value. The general loss rate of the fruit is about 20-30% , if measu...

Problems solved by technology

However, since the adults do not emerge at the same time, the lure is sprayed on the orange orchard plants, and the adults in the egg-laying period still have the opportunity to choose to lay eggs on the orange orchard, which is an important reason why the control effect is still not ideal; moreover , for the treatment of picking insects and fruits, the public plan uses biogas digesters, and the effect is very good, but not all fruit farmers have biogas digesters, and some biogas cement ponds have not been used for a long time and cracked and cannot meet the basic requirements for handling insects and fruits. The timely and effective treatment of the results, therefore, the scope of application of its technical solutions is limited
