Problems solved by technology

[0003] At present, there are few studies on the control of Chestnut beetle, and the control methods for Chestnut beetle are mainly artificial capture of adults, use of black light to trap and kill adults, and release of natural enemies in the larval stage, etc.
[0004] Since most oak forests are located in mountainous areas without electricity, conventional black lights are inconvenient to use at present; the current special black light uses batteries, but needs to be charged every day, and it is also inconvenient to use in some forest areas with deep mountains and deep ditches.

specific Embodiment approach

[0016] The special attractant for trapping and killing adults of Chestnut beetle beetle of the present invention, its preferred embodiment is:

[0017] The special attractant includes a mixture of the following substances in the following mass ratios:

[0018] Sugars: acids: related compounds: purified water = 30:10:1:59;

[0019] The related compounds are formulated according to the nutritional components in the bark sap of tree species harmed by Chestnut beetle.

[0020] The tree species endangered by the Chestnut beetle include Quercus liaotungensis and / or Quercus mongolica.

[0021] The special-purpose trapping and killing agent for trapping and killing the adult beetle beetle of the present invention, its preferred embodiment is:

[0022] Add 1% mass ratio of deltamethrin stock solution to the above-mentioned special attractant.

[0023] The forest application method of trapping and killing adults of Lishan longhorn beetle of the present invention, its preferred embodi...

specific example 1

[0032] Concrete example 1, indoor test screens the attractant that attracts the adult beetle beetle.

[0033] Collect the sap from the wounds of oak trees where the adult Chestnut beetle provided nutrition, and bring them back to the room, and analyze and test the main chemical substances and the ratio of each substance with LC / MS instrument.

[0034] According to the main chemical substances in the sap, buy the corresponding chemicals. Experiments were carried out in the forest farm of Daxicha Town, Kuandian County, Liaoning Province. During the eclosion period of adults of Chestnut beetle, black light was used to lure or artificially capture adults, and a certain number of newly emerged adults of Chestnut longhorn beetle were collected for indoor experiments. Select 100 adult insects and place them in a sarong of 3.5m×3.5m×3m. Put 10 pieces of Quercus liaotungensis about 1m in length and diameter greater than 20cm in the cage. The branches and leaves of common tree species ...

specific example 2

[0036] Concrete example two, the optimal attractant that lures the chestnut beetle adult is screened in the forest.

[0037] In the forest, 30 Quercus liaotungensis, which were seriously damaged by the Chestnut longhorn beetle, were randomly selected, and each tree was released with one attractant and one device screened out by laboratory tests. Observe the trapping effect at 18:00-22:00 during the peak activity period of Lishan longhorn beetle adults in the forest, and record the number of lures. If the adults who come to feed are found, they are captured and bottled. The sucking action is used as the standard for feeding , and finally record the total number of Lishan longhorn beetle adults attracted by each attraction point, calculate the average value, and perform statistical analysis.

Abstract

The invention discloses a special attractant for trapping and killing adults of Chestnut beetle, the attractant and its application method in the forest. The special attractant includes sugars:acids:related compounds:purified water=30:10:1:59 mass ratio The mixture of related compounds is formulated according to the nutrients in the bark sap of the species of Chestnut longhorn beetle. The special attractant is to add 1% mass ratio deltamethrin stock solution to the above special attractant. Applying this method in the forests of Mongolian oak forest, Liaodong oak forest or other tree species endangered by Chestnut beetle can not only attract a large number of Chestnut beetle adults, but also effectively kill them. It has low cost, easy to use, and is environmentally safe. The advantages.

Description

technical field [0001] The invention relates to a prevention and control technology for trapping and killing adults of Chestnut beetle, in particular to a special attractant and trap for trapping and killing adults of Chestnut beetle and its application method in forests. Background technique [0002] Chestnut beetle mainly harms oak trees (Quercus mogolica and Quercus liaotungensis) in the forest areas of Northeast China. In recent years, it has caused disasters in Jilin, Liaoning Province and Chifeng City, Inner Mongolia, with an area of ​​102,000 hectares. It is still spreading , has caused a major threat to the natural forest dominated by oak trees in the forest region of Northeast China. Chestnut beetle feeds on tree trunks with larvae. In severely damaged forests, the trunks of the damaged trees are riddled with holes, and some even die. [0003] At present, there are few studies on the control of Chestnut beetle, and the control methods for Chestnut beetle are mainly...
