First, technical measures
(1) The time of trapping and control of the poplars through the prevention and control techniques: In a representative woodland, early trapping observation is performed. When the first male moth was induced, a large area of ​​control began.
Trapping method: Apply dry nail wicking method. In the woods, traps are set at a checkerboard level of 0.2 to 0.3 hectares, and forest margins are set appropriately. In the forest for forest protection, 150-200 meters is set up with a trap site, which is lined up at equal distances. The core of the lure is nailed in the middle of the plastic surface and is fixed on the sunny side of the tree trunk 1.3 to 1.5 meters. The trap was coated twice with 20 grams each time. In the nursery and young forest, make a sign and apply rubber cores.
(II) Prevention and Control Measures of Yang Gan Xiang Jia
1. According to the principle of timely early prevention, prevention of leakage, light treatment, minor treatment, and control of insect source wood, the organic coordination among counties and counties, townships, and townships shall be organically coordinated. One, gradually expanding the protected area, shrinking the epidemic area.
2. Divide the types of disasters and classify policies. The plots that are designed to prevent and control are to be kept in forests that are small in age and are lightly damaged (the age of the trees is less than 6-8 years old, and the damage rate is less than 10%); the old forest belts, isolated woods, and forests that were heavily damaged are lumps. Distribution should be given priority to the design of cutting, cleaning insect source wood.
3. Planting wood traps, concentrated treatment.
4 chemical control, the use of insecticidal superior solution, or omethoate 50 times liquid, smear wormholes. The prevention and treatment time begins with larvae infestation and begins to discharge wood chips in the intrusion hole. If necessary, secondary control is performed.
(III) Prevention and Control Measures of Cattle Breeds
1. Afforestation measures, optimization of tree structure, construction of mixed forests, and the formation of forest structures with certain self-control abilities.
For those old-aged trees with no prevention and control value in the hardest-hit areas, priority will be given to cutting and updating. After the middle-aged and young-aged trees are removed, they can be regenerated or renewed.
(2) Physical measures: Artificial trees or high-dry truncations can be carried out on the damaged trees, and the insects can be cut and burned.
3. Chemical control, the use of insecticidal superior, omethoate dots coated wormholes or adult emergence of spraying control of adult insects.
Second, organization and management measures
1. Vigorously publicize and implement the Regulations on Forest Pests and Diseases. Based on the principle of “prevention first, comprehensive management†and the principle of early, small, and minimal governance, implement the responsibility system of “who manages and who controlsâ€.
(2) Sign the responsibility system for prevention and control at all levels, integrate the prevention and control tasks into the targets of the leadership at all levels, implement responsibilities, and sign prevention and control contracts at all levels, with awards and penalties. Where the prevention and control task has not been completed or the prevention and control standards have not been met, the notification system for the removal of pollutants within the time limit shall be implemented. Economic sanctions shall be imposed if there is no prevention or control within the time limit or if the prevention and control standards are not met.
