technical field

The invention relates to the field of horticultural science research, more specifically to a method for preventing and controlling citrus longhorn beetle, and also relates to a device (Fangniubao) for preventing and controlling citrus longhorn beetle.

Background technique

The citrus longicorn is the main pest that harms citrus trees, and it brings serious harm to the production of citrus. Although the occurrence of longicorn beetle can be reduced through pesticide control, it consumes a lot of pesticides and wastes manpower and financial resources. At the same time, my country is vigorously carrying out crop reduction. Therefore, it is of great significance to establish a set of green and environmental protection prevention and control technology for increasing the yield of citrus, improving the quality of citrus and reducing the use of pesticides. The citrus longhorn is a typical branch pest. It mainly damages the root and neck. It eats the trunk with larvae, penetrates into the xylem, and bores outwards to ventilate the defecation holes, forming tunnels. There are dung debris, which weakens the tree vigor. The trunk is often riddled with holes.

Contents of the invention

B. Determination of the use time of Fangniubao: Every year when the adult beetles are not active, wrap the trunk with Fangniubao. The adult citrus beetles in Hunan generally begin to appear at the end of April and early May. Before mid-April, Use Fangniubao to prevent and control the damage of citrus beetles;

C. Determination of the use position of anti-niubao: Fangniubao is used in the trunk 0-50 cm above the ground. The survey found that longhorn beetle eggs are mostly produced at the base of the trunk within 50 cm from the ground, and a few can be as high as 30-60 cm. Bao is mainly used for citrus trunks within 50 cm from the ground;

D. Treatment of citrus trees before using Fangniubao: Before using Fangniubao, carefully check whether longhorn beetle larvae exist in the tree, and use a wire hook to hook out the larvae and kill them. Beetles have become the main pests faced by citrus trees. Although there are many chemical and physical control methods to reduce the damage of citrus beetles, it is inevitable that some fruit trees in citrus orchards will suffer from long beetles. Therefore, the first use of Fangniubao citrus In the orchard, it is necessary to check whether there are beetle larvae in the tree body. For the tree body with larvae, use a wire hook to hook out the larvae and kill them. By adopting this technical measure, it can prevent the beetle larvae that have entered the citrus tree from being damaged. Anti-Niu Bao;

E. How to use Anti-Niubao: before the star ox lays eggs, use Anti-Niubao to wrap around the base of the trunk for 2-3 turns. When winding, the hook side of the devil sticks outward, and then sticks the hook with the hairy side of the devil for a circle. , and cultivate soil to the bandage to prevent the lower base from being exposed;

F. After using the anti-niubao, check once a month whether the used anti-niubao is intact: repair and replace the damaged anti-niubao. The nylon mesh of the model is sewed and repaired, and the anti-niubao with a large degree of damage is replaced with a new anti-niubao;

G. After using Fangniubao, check whether there are beetle larvae in the tree once a month: For trees that still have longicorn larvae in the trunk after using Fangniubao, use a wire hook to hook the larvae after removing the Fangniubao Take out, kill, and replace with a new anti-cow treasure.

By adopting the above-mentioned technical measures, the difficult problem of large-scale use of pesticides in the prevention and control of citrus longhorn beetles has been changed. The above technical measures can effectively prevent the damage of citrus longicorns to citrus trees, control the incidence of citrus longicorns below 0.1%, effectively prevent the trunks of citrus longicorns from being harmed by longicorn beetles, increase the fruit bearing capacity of citrus trees and prevent windbreaks The ability to increase the yield of citrus by about 5%-10%.

A device for preventing and controlling citrus beetles (anti-niubao), which consists of three parts, including a nylon net, a hook surface with a devil and a hair surface with a devil. The hook side faces up, and there is a devil stick hook surface in the middle and bottom of the nylon net, and three devil stick hair sides of a certain length for use. Spawnable space. The effect of sewing the hook surface of the Velcro on the nylon net is that when the nylon net is wrapped on the trunk of the citrus tree, the hook surface of the Velcro can be used to fix the nylon net on the trunk of the citrus tree by using the wool surface of the Velcro.

A method for preventing and controlling citrus beetle, the steps are:

A. Determine the time to use Fangniubao: Every year when the adult beetles are not active, wrap the trunk with Fangniubao. The adult citrus beetles in Hunan usually begin to appear at the end of April and early May. Before mid-April, use Fangniubao prevents and controls the damage of citrus beetles;

B. Determine the location where the anti-niubao is used: the anti-niubao is used when the trunk is 0 or 10 or 20 or 30 or 40 or 50 centimeters from the ground (the anti-niubao wraps the trunk 0-50 centimeters from the ground). The eggs are mostly produced at the base of the trunk within 50 cm from the ground, and a few can be as high as 60 cm. Fangniubao is mainly used for citrus trunks within 50 cm from the ground;

C. Treatment of citrus trees before using Fangniubao: before using Fangniubao, carefully check whether there are beetle larvae in the tree body. For the tree body with larvae, use a wire hook to hook out the larvae and kill them. The beetle has become a citrus tree. The main pests we face, although there are many chemical and physical control methods can reduce the damage of citrus longicorns, but some fruit trees in citrus orchards are inevitably damaged by longicorn beetles. Check whether longicorn larvae already exist in the tree body. For the tree body with existing larvae, use a wire hook to hook out the larvae and kill them. By adopting this technical measure, it can prevent the longicorn larvae that have entered the citrus tree body from damaging Fangniubao;

D. How to use Anti-Niubao: Before Xingtianniu lays eggs, use Anti-Niubao to wrap around the base of the trunk for 2-3 turns. When winding, the hook side of the devil sticks outward, and then sticks the hook with the hairy side of the devil for 1 turn. , and cultivate soil to the bandage to prevent the lower base from being exposed;

E. After using the anti-niubao, check once a month whether the anti-niubao is in good condition: repair and replace the damaged anti-niubao. For small damage, you can remove the protective cover, and use the same type of nylon mesh to sew and repair; for the more damaged protective cover, replace it with a new one;

F. After using Fangniubao, check whether there are beetle larvae in the tree once a month: after using Fangniubao, there are still longicorn larvae in the tree trunk. Hook it out, kill it, and replace it with a new anti-cow treasure.

This technology uses physical control to block the spawning environment of the citrus longhorn beetle from the source. Compared with the use of chemicals to control the citrus star beetle, it can achieve zero pesticide use. Simultaneously, adopting the present invention can control the incidence rate of citrus longicorn beetle below 0.1%, can effectively prevent citrus trunks from being harmed by longicorn beetle, increase the capacity of citrus trees to bear fruit and prevent wind-damaged plants, and increase the yield of citrus by 5%-10%. about.
