Problems solved by technology

One is to release the lure liquid directly into a polypropylene bottle or metal bottle with an opening. This release method has the following defects: (1) Because the bottle mouth is open, rainwater easily flows into the bottle through the bottle mouth and mixes with the attractant to change the attractant. The composition and ratio of the attractant will reduce the effect of attracting insects; (2) The attractant liquid is exposed to direct sunlight and directly exposed to the air, and the active ingredients of the attractant are easily oxidized and deteriorated, which will affect the effect of field use; (3) In the wild, the trap is affected by wind and other factors, and the trap with the attractant falls to the ground from time to time, resulting in the loss of the attractant liquid, which needs to be added again, resulting in waste; (4) The amount of lure liquid used Large, generally more than 300ml, it is not convenient to transport, carry and install in the field
The second release method is to directly encapsulate and release the lure with polyethylene film. The disadvantage of this method is that the release rate of the attractant is high, and the lure core has a short duration, generally no more than 2 weeks, and the lure core needs to be replaced frequently. High manpower and material costs

Embodiment 1

[0022] 1. Preparation of attractant lure cores for adult monochamus alternatus

[0023] The attractant liquid of the adult monochamus alternatus is produced according to the invention patent "A kind of attractant of monochamus adult (publication number: CN102986739A)".

[0024] Specifically prepare the following lures:

[0025] (1) Polyethylene film (PE) packaging: put a small amount of absorbent cotton into a PE bag (film thickness 70 microns), add 20g of attractant liquid, and heat seal until airtight;

[0026] (2) Cast polypropylene film (CPP) packaging: put a small amount of absorbent cotton into a CPP bag (film thickness 70 microns), add 20g of attractant liquid, and heat seal until airtight;

[0027] (3) High-temperature-resistant polyester-polyethylene co-extrusion film (PET / PE) packaging: put a small amount of absorbent cotton into a PET / PE bag (film thickness 70 microns), add 20g of attractant liquid, and heat seal until airtight;

[0028] (4) Polyvinyl chloride-p...

Embodiment 2

[0038] Field Test of Lures Prepared by PA / PE Films with Different Thicknesses

[0039] Lure core preparation: put a small amount of absorbent cotton into PA / PE co-extruded film bags (film thicknesses are 30, 50, 70, 100, 150, 200 microns respectively), and cut one on each side of the bag with a diameter of 0.5 cm Open the hole, then add 20g of attractant liquid, heat seal, and then use PE bag (film thickness 70 microns) to heat seal the PA / PE co-extruded film bag containing attractant liquid until airtight; use the above prepared The lure cores were tested in the field (Table 2).

[0040] The field test was carried out in Taining, Fujian Province (May 26, 2014-July 21, 2014). The trap used was made according to the patent "A Trapper for Monochamus alternatus" (public number: CN203313934U); The space was repeated, each treatment was sorted randomly, and the interval between adjacent traps was 80-100 meters. The number of monochamus captured by each trap was collected and cou...

Embodiment 3

[0045] Field test of lures prepared by secondary packaging with PE films of different thicknesses

[0046]Lure core preparation: put a small amount of absorbent cotton into a PA / PE co-extrusion film bag (film thickness 70 microns), and cut a hole with a diameter of 0.5 cm on each side of the bag, and then add 20g of attractant liquid, Heat-sealing, and then heat-sealing the PA / PE co-extruded film bag containing the attractant liquid with a PE bag (film thicknesses of 30, 50, 70, 100, 150, and 200 microns respectively) until airtight; The lure cores were tested in the field (Table 3).

[0047] The field test was carried out in Taining, Fujian Province (May 26, 2014-July 21, 2014), and the trap used was made according to the patent "A Trapper for Monochamus alternatus" (public number: CN203313934U); The space was repeated, each treatment was sorted randomly, and the interval between adjacent traps was 80-100 meters. The number of Alchachata raptors captured by each trap was c...

Abstract

The invention provides a preparation method of an attracting core of insect attractant, in particular to an attracting core of monochamus alternatus hope adult attractant and a preparation method thereof. The preparation method comprises steps of putting little absorbent cotton into a PA/PE co-extrusion membrane bag with membrane thickness of 30-200 micrometers; cutting 1-1.5 holes with diameter of 0.5 cm in two sides of the bag; adding 20-250 g attractant liquid and performing heat sealing; and performing heat sealing on the PA/PE co-extrusion bag containing the attractant liquid until by use of a PE bag with membrane thickness of 30-200 micrometers until the bag is tightly sealed. In this way, lasting period of the attracting core in the wild can be extended to less than 8 weeks; the attractant liquid is arranged in the PE bag, so the attracting core is small in size and easy to transport, carry and install in the wild, and material resources and labor cost for attraction and capturing of monochamus alternatus hope are greatly reduced.

Description

technical field [0001] The invention belongs to a preparation method of an insect attractant lure core, and more particularly relates to an adult montina monochamus attractant lure core and a preparation method thereof. Background technique [0002] 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. [0003] 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 ...
