preparation example Construction

[0060] The preparation method of the monochamus alternatus luring device of this embodiment comprises the following steps:

[0061] Step 1: Mix turpentine, ethanol, and acetaldehyde according to the above-mentioned volume percentages to form a plant-derived pheromone liquid, and put a set amount of cotton 22 in the second slow-release bag 21, and pour it into the second slow-release bag Add a set amount of plant-derived pheromone liquid to 21, so that the plant-derived pheromone liquid is absorbed in the cotton 22, and then seal the mouth of the second slow-release bag 21 to obtain the second slow-release body 2;

[0062] Step 2: Encapsulate the aggregated pheromone in the capsule shell to make a capsule 14 through microcapsule embedding technology, absorb a plurality of the capsules 14 on the cotton core 13, and then place the cotton core 13 is installed in the plastic tube 12 that one end is open, and then the plastic tube 12 is packed in the first slow-release bag 11, and t...

Embodiment 1

[0069] Embodiment 1, make a kind of plant source pheromone according to table 1, its component and volume ratio remain unchanged, plant source pheromone is made up of following components by volume percentage: turpentine 36ml, ethanol 18ml, acetaldehyde 6ml, Then the three components are mixed to form a plant-derived pheromone liquid, and then encapsulated in the second slow-release body according to the preparation method of the above-mentioned attracting device, and ten second slow-release bodies are made in the same way. One of the second slow-release bodies is not paired with the following first slow-release body, and the other nine are all paired with one of the following first slow-release bodies.

[0070]Prepare an aggregation pheromone according to A2-A5 of Table 1, and its component is 2-undecyloxy-1-ethanol. And divided into four different volumes: 0.04ml, 0.06ml, 0.08ml, 0.1ml, and then encapsulated in the above-mentioned first slow-release body according to the abo...

Embodiment 2

[0079] Example 2. According to the formulations B1-B7 in Table 2, plant-derived pheromones are made, with the same components and different volume ratios, and then the three components are mixed to form plant-derived pheromone liquids, and then according to the preparation method of the above-mentioned attracting device Encapsulated in the second sustained-release body, forming seven different second sustained-release bodies. Each second sustained release body is paired with one of the first sustained release bodies described below.

[0080] According to the composition and volume ratio of formula B8 in Table 2, plant-derived pheromones are prepared, and then encapsulated in the second slow-release body according to the preparation method of the above-mentioned attracting device to form the eighth second slow-release body, and the eighth second slow-release body. The release body is paired with one of the primary sustained release bodies described below.

[0081] According to...

Abstract

The present invention relates to a monochamus alternatus attractant, its attracting device and the preparation method and application of the attracting device. The monochamus alternatus attractant includes plant source pheromone and aggregation pheromone, and the plant source pheromone and the The aggregation pheromones interact synergistically to attract Monochamus alternatus; the plant source pheromones are composed of the following components by volume percentage: turpentine 50-80%, ethanol 10-40%, acetaldehyde 5-10% ; The aggregation pheromone is 2-undecyloxy-1-ethanol. The monochamus alternata attractant of the invention has good attracting effect. The attracting device includes a first slow-release body and a second slow-release body, and the first slow-release body and the second slow-release body are simultaneously installed on the Monochamus alternatus trap to gather pheromone and plant source information hormone release. The lure device is easy to use, has good slow-release effect and long drug effect period, can greatly reduce the population density of Monochamus alternatus, and curb the spread and transmission of pine wood nematode disease.

Description

technical field [0001] The invention relates to the technical field of insect control, in particular to a monochamus alternatus attractant, an attracting device, a preparation method and application of the attracting device. Background technique [0002] Monochamus alternatus Hope (Monlchamus alternatus Hope), belongs to the order Coleoptera, Cyceropteridae, subfamily Alchamus alternatus, and the genus Monlchamus. Monochamus alternata not only damages weaker trees with larva borers, but also destroys the xylem and phloem of trees, resulting in insufficient or interrupted water and nutrient transport, seriously affecting the growth of pine trees, and even causing pine trees to die in patches. What's more serious is that the adult pine beetle is also the main carrier of the devastating disease of pine trees - Bursaphelenchus xylophilus, which is called "the cancer of pine trees" by researchers all over the world. In Japan, pine wood nematode was first discovered in Nagasaki C...
