Problems solved by technology

[0003] At present, the prevention and control of pine weevil larvae is mainly based on poisoning, which mainly includes cutting down the damaged wood and burning it, and fumigation of diseased and dead wood. This is generally time-consuming and laborious, and is not conducive to large-scale control of forest farms.
For the prevention and control of pine weevil adults, there are mainly trapping and killing methods such as flying control, black light and traps. The use of flying control methods is likely to cause large-scale spread of pesticides, killing pine weevils and threatening the survival of its natural enemies, and the price is relatively high. High is not conducive to promotion, black light and other traps need a lot of manpower and material resources, while traps are cumbersome to operate, high in price, and easy to be destroyed

Embodiment 1

[0017] Preparation: (+) α-pinene: 1.6 parts, (-) β-pinene: 1.2 parts, camphene: 0.4 parts, myrcene: 0.8 parts, ethanol: 0.8 parts, polyisobutylene: 5 parts, thiacloprid microcapsules : 0.1 part, antioxidant BHT (2,6-di-tert-butyl-p-cresol): 0.1 part.

[0018] The pine tumor trapping agent obtained in Example 1 has good viscosity, high durability, and is not easily deformed by wind, sun, and rain, and its practical application in the field can reach more than three months. In Zengcheng forest farm experiment of South China Agricultural University, glue was sprayed on pine trees with poor growth and less rosin secretion (pine nodules generally lay eggs on poor pine trees) or traps were sprayed on pine twigs (pine nodules) Adult elephants need to feed further to develop). Because the decoy agent also has the attractant ingredient of pine tumors, it has a certain attracting effect. Examples show that: a small number of pine tumors are adhered to the tree trunk sprayed with traps...

Embodiment 2

[0020] Preparation: (+) α-pinene: 1.6 parts, (-) β-pinene: 0.8 parts, camphene: 0.3 parts, myrcene: 0.8 parts, ethanol: 1.0 parts, polyisobutylene: 5 parts, bifenthrin micro Capsule: 0.3 parts, anti-aging agent AW: 0.2 parts.

[0021] The pine tumor trap obtained in Example 2 has high insecticidal effect, is resistant to ultraviolet radiation, and is not easily denatured at high temperature. It can be used in the field for more than three months and is suitable for application in high temperature seasons. Examples show that the peak period of pine tumor activity is from June to July, and the temperature is in the season of rising. In the experiment of Wuhua Forest Farm in Meizhou, spraying the trap on the surface of the trapping device for pine tumors can significantly increase the trapping capacity of the trapping device. Statistics show that the trapping capacity is 30% higher than that of the trapping device for pine tumors without spraying traps, and The effect lasts for ...

Abstract

The invention relates to an attractive toxicant for Sipalus gigas. The attractive toxicant for Sipalus gigas is prepared by mixing 1.6 to 2.2 parts of (+)-alpha-pinene, 0.8 to 1.4 parts of (-)-beta-pinene, 0.3 to 0.5 part of camphene, 0.6 to 1.0 part of laurene, 0.8 to 1.0 part of ethanol, 5 to 6 parts of polyisobutylene, 0.1 to 0.3 part of an insecticidal microcapsule and 0.05 to 0.2 part of an antioxidant. The attractive toxicant for Sipalus gigas has the characteristics of viscosity, long action time, no proneness to denaturation under any weather condition, etc. The attractive toxicant is highly attractive to Sipalus gigas and simple to use; a spraying apparatus is used for spraying the attractive toxicant for Sipalus gigas to a pine forest in an affected area; the attractive toxicant can attract and poison Sipalus gigas, and escaped Sipalus gigas is poisoned due to adherence onto a spraying agent containing a thiacloprid microcapsule; and the attractive toxicant is convenient to produce, low in production cost and suitable for promotion and application in a forest farm and a scenic region, and has wide development prospect.

Description

technical field [0001] The invention relates to a pine weevil attractant. Background technique [0002] Pine weevil (Hyposipalus gigus Linnaeus) is one of the main trunk-boring pests of pine trees in my country. It mainly harms weakened and felled trees of Pinus massoniana, especially large-diameter pine trees. The damaged wood is bored into holes, and the holes are as deep as the xylem, and can even penetrate the wood, causing the pine tree to die, and the wood completely loses its technological value, causing greater economic losses. Therefore, the effective control of the population and growth trend of Pine Tulip will help to protect the economic pine forest and landscape pine forest. [0003] At present, the prevention and control of pine weevil larvae is mainly based on poisoning, which mainly includes cutting down the damaged wood and burning it, and fumigation of diseased and dead wood, which is generally time-consuming and laborious, and is not conducive to large-sc...
