Comparative example 6 LU503695

Mixing avermectin and sawdust according to the mass ratio of 1: 7 to obtain a first mixture, and drying the first mixture in a drying box (ensuring that the water content of the first mixture is less than or equal to 1%); the first mixture and brown sugar water are fully stirred to ensure that the termite bait is in a state of "holding it into a ball and dispersing it when gently squeezed", thus forming the termite bait.

Comparative example 7

Mixing avermectin and sawdust according to the mass ratio of 1: 8 to obtain a first mixture, and drying the first mixture in a drying box (ensuring that the water content of the first mixture is less than or equal to 1%); the first mixture and brown sugar water are fully stirred to ensure that the termite bait is in a state of "holding it into a ball and dispersing it when gently squeezed", thus forming the termite bait.

In the implementation of the invention and the comparative example, the number of termites used is 100, and they are randomly assigned to each group by being arrested in the ant nest, so as to ensure that only the control is different and other conditions are the same. Specifically, the termite baits prepared in Example 1 and Comparative Example 1 and Comparative Example 7 were placed in different areas of the field forest, and 100 termites in each area were placed at a distance of 2 meters from the sample, and the number of termites tending to the termite baits and the number of deaths were observed.

The results are shown in Table 1.

Table 1 LU503695

Trend (number) | Death (number) Mortality rate

Comparative 50 42 84.00% example 1

Comparative 32 80.00% example 2

Comparative 93 96.77% example 3

Comparative 87 83 95.40% example 4

Comparative 83 79 95.18% example 5

Comparative 96.97% example 6

Comparative 100 98.00% example 7

As can be seen from Table 1, the mortality rate in the example is the highest, indicating that its trapping and killing effect is the best, and its trend effect on termites is also the best; in addition, comparing Comparative Example 1 and Comparative Example 2 with Example 1, it can be seen that the trend effect on termites is obviously greatly reduced. In Comparative Example 1, brown sugar water is replaced by water, and pine sawdust is replaced by flour in Comparative Example 2, so it can be known that pine sawdust and brown sugar will stimulate termites to eat. Comparative example 3-7 is to adjust the mass ratio of pesticide (avermectin) and pine sawdust to further determine its optimum mass ratio. The data show that the trapping and killing effect is the best when the mass ratio of pesticide (avermectin) and pine sawdust is 1: 6.

To sum up, the invention gives full play to the double temptations of brown sugäH503695 water and pine sawdust, and stimulates termites to feed to the maximum extent. With a small amount of chemicals as the guide, under the premise of ensuring no harm to the environment and human beings, the worker ants transport the sawdust with termite bait to other termites’ holes to eat, thus causing a long-term and remarkable trapping and killing effect on termites, combining chemical control with physical control, giving full play to its synergistic effect and achieving good control effect; the raw materials used are safe for people and livestock, do not pollute the environment, and have the characteristics of long-acting, non-toxic, environment-friendly and low cost; the above components cooperate and promote each other, so that the obtained termite bait has a good contact killing effect on termites and does not produce drug resistance; the method of the invention can further improve the trapping effect by controlling the proportion of raw materials, and the preparation process is simple.

The above-mentioned embodiments only describe the preferred mode of the invention, and do not limit the scope of the invention. Under the premise of not departing from the design spirit of the invention, various modifications and improvements made by ordinary technicians in the field to the technical scheme of the invention shall fall within the protection scope determined by the claims of the invention.
