Description

A kind of synergistic coating material for monochamus trap and preparation method thereof

technical field

The invention relates to a synergistic coating for an insect trap, and more particularly relates to a synergistic coating material for a monochamus trap and a preparation method thereof.

Background technique

Pine wood nematode disease, also known as "pine cancer", is a devastating disease of pine trees, which can cause the affected pine trees to wither and die quickly within 1 to 2 months. According to statistics, since 1982, the direct economic loss caused by pine wood nematode in my country has exceeded 50 billion yuan. So far, pine wood nematode disease has caused serious harm in the Yangtze River Basin and most provinces south of my country, and it is spreading rapidly, posing a huge threat to the safety of my country's forest ecological environment.

Monochamus monochamus is the main vector insect of pine wood nematode disease in my country, also known as monochamus alternatus, which mainly transmits pine wood nematode disease through behaviors such as feeding with pine wood nematodes by adults. So far, controlling the monochamus and cutting off the transmission route of the disease is still one of the most effective methods for controlling pine wood nematode in my country. Installing the lure core with attracting activity on the adult pine brown monochamus on the trap, and hanging it in the pine forest to trap the adult pine brown monochamus, can effectively prevent and control the pine brown monochamus, and inhibit the development of pine wood nematode disease. Diffusion spread.

In the trapping control of Monochamus alternatus, in addition to the lure core with attracting activity, the trap is also an important factor affecting the trapping effect. When used in conjunction with the same lure core, there were significant differences in the trapping efficiency of different types of traps for Monochamus alternatus. At present, a variety of monochamus traps have been used in production practice, such as: "Monchachamus trap" (patent application number: 200920111229.7) and "a monochamus trap" (patent application number : 201320321116.6), etc. Most of these traps are made of polypropylene or tinplate, and their structures are similar. The core lures the adult pine beetle to fly to the trap, and when the adult beetle hits the insect baffle, it falls into the insect collection bottle through the insect catcher, thereby achieving the effect of trapping and preventing.

However, field observations have found that some monochamus adults can stay on the baffle plate of the trap, and use the baffle plate as a force point to take off and escape; on the traps, and escaped with the catchers as the focus; the escape of these pine nuts seriously affected the effect of trapping and control, resulting in an increase in the number of adults around the traps, and a large number of pine trees were infected with pine trees. Concentrated death due to wood nematode disease.

Contents of the invention

In order to solve the above problems and prevent or reduce the escape of the monochamus alternatus, the invention provides a synergistic coating material for the monochamus trap and a preparation method thereof. The coating material is simple in composition, easy to manufacture and low in cost, and the coating material on the trap can effectively prevent the escape of the monochamus alternatus and significantly improve the trapping efficiency of the trap.

In order to achieve the above object, the technical scheme that the present invention takes is as follows:

The synergistic coating material of the monochamus trap of the present invention contains turpentine, sliced paraffin, molybdenum disulfide and melamine cyanurate; further, calculated according to parts by weight, the raw material of the synergistic coating consists of : 10 parts of turpentine, 3 to 4 parts of sliced paraffin, 1 to 3 parts of molybdenum disulfide and 1 to 3 parts of melamine cyanurate; preferably, the quality of molybdenum disulfide and melamine cyanurate in the raw materials of the material The ratio is: 1:2~2:1; more preferably, the mass ratio of molybdenum disulfide and melamine cyanurate in the raw material of the material is: 1:1.

The mass fraction of the turpentine is more than 90%, the particle size of the molybdenum disulfide is 1-50 microns, and the particle size of the melamine cyanurate is 1-25 microns.

The specific preparation method of the synergistic coating material is:

Put the sliced paraffin into a beaker, then add turpentine, gradually heat to 50-60°C until the paraffin is completely dissolved, slowly add melamine cyanurate under stirring at 50-100 rpm, and then slowly add 1-3 parts of Molybdenum disulfide, keep stirring at 50-60°C for 10 minutes to obtain the synergistic coating material for the trap of the monochamus.

A kind of application of the synergistic coating material of the monochamus trap made by the above-mentioned preparation method: brush the synergistic coating material on the surface of the insect retaining plate and the insect catcher of the trap, and let it dry in the air. Dry, to aid in the trapping of Monochamus alternatus.

The beneficial effects of the present invention are:

(1) The composition of the synergistic coating material of the present invention is simple, the production cost is low, the operation is simple, safe and environmentally friendly, and the use effect is good. The paraffin itself has a lubricating effect, and other lubricating materials can be evenly fixed on the insect trap and the contact plate of the trap. On the surface of insects, melamine cyanurate and molybdenum disulfide are used in combination, which can not only increase the dispersion of lubricating materials in the medium, but also reduce the friction coefficient, which has obvious advantages;

(2) Brushing the synergistic coating of the present invention on the surface of the insect trap of the monochamus trap and the inner surface of the insect catcher with a soft brush can effectively reduce the escape of monochamus adults and significantly increase The insect-catching efficiency of the monochamus trap improves the effect of trapping and controlling the monochamus, reduces the number of dead pine trees in the epidemic area, and inhibits the spread of pine wood nematode disease.

Detailed ways

There are three kinds of traps used in field tests, namely: (1) SYY-4075A white iron baffle trap (manufactured by Nanjing Shengxing Biotechnology Co., Ltd.); (2) polypropylene funnel trap (Zhangzhou Yingge Er Agricultural Technology Co., Ltd.); (3) ZM-60 polypropylene baffle trap (Xiamen Sanyong Biotechnology Co., Ltd.). In the field test, the three kinds of traps were treated with synergistic coating and control without synergistic coating. For various traps with synergistic coating treatment, the synergistic coating of the made monochamus trap is evenly brushed on each surface of the insect retaining board and the inner surface of the insect catcher with a soft brush. Allow to dry for 24 hours before use.

Field tests were carried out in Quanzhou, Fujian (May 2-30, 2014) and Xiamen, Fujian (June 4-25, 2014). The experiment was repeated in 5 spaces, each treatment was randomly sorted, the interval between adjacent traps was 80-100 meters, and the lures were replaced every 7 days, and the number of Altsia monochamus captured by each trap was collected and counted. The test results of the two places are shown in Table 1 and Table 2 respectively.

Both Table 1 and Table 2 show that when the same trap is used to trap Monochamus alternatus, the traps coated with synergistic coating can capture significantly more Monochamus alternatus than the traps without synergistic coating, The synergistic coating prepared by the invention has a significant synergistic effect on the trapping of the monochamus.
