In recent years, the pine wood nematode disease presents new characteristics, and the occurrence area breaks through a theoretical north suitable habitat and spreads to Liaoning areas and other areas; the susceptible tree species are expanded from the original black pine, pinus massoniana and the like to almost all the Pinaceae plants, and the prevention and treatment situation is very severe. In Japan and China, monochamus alternatus is the main transmission medium of the pine wilt disease, and after the monochamus alternatus emerges, the body carries a large number of nematodes to transmit the pine wilt disease in the stages of nutrition supplement and egg laying. Research shows that each monochamus alternatus hope can cause 4.06 masson pines with the average age of 18 years to infect the pine wilt disease to die in the nutrition supplementing stage.

The solar light source trap consists of a solar panel, a rain cover, 4400mA and 3.7V lithium batteries, a light sensing controller, an LED light source, a cross plate, a funnel and a collecting cup, and can continuously work in 7 rainy days. 5 traps are arranged in each treatment and are randomly distributed, and the interval between every two traps is 30-40 m. Traps were tested every 4-5 days, starting in 2019 at month 5 and continuing until month 8 ends. This time was just the major period of monochamus alternatus imago activity, and the number of monochamus alternatus lured per trap was recorded. The specific embodiment scheme is as follows.

Table 1 different band solar energy embodiments (zhejiang linan, 2019, 5.10-5.24, N ═ 5)

The results of example 1 show that the number a trap was the highest reaching 68, significantly higher than the other numbered bands, where the number a trap was 2.62 times that of number E and 3.09 times that of number D.

Example 2:

The result of example 2 shows that the trapping amount of 365-.

Example 3:

table 3 different light source power and solar panel power embodiments (zhejiang lian, 2019, 6.8-6.22, N ═ 5)

The results of example 3 show that different powers of the LED light source and the solar panel power both have a significant effect on monochamus alternatus trapping. The trapping amount is larger as the power of the LED light source is higher under the condition that the power of the solar panel is the same, wherein the number C5W LED light source is 2.23 times of the trapping amount of the number A and 1.57 times of the trapping amount of the number B. In addition, under the condition of the same power of the LED light source, the trapping amount of the solar panel is larger as the power of the solar panel is higher, wherein the trapping amount of the 22W solar panel of the number E is improved by 10.3 percent compared with the number C and is improved by 82.9 percent compared with the number D.

Example 4:

the Monochamus alternatus attractant part of the trapping embodiment is prepared by mixing plant source pheromones (a-pinene, turpentine, ethanol, guaiacol and the like) according to a certain proportion, putting the mixture into a slow release bottle (low-density polyethylene), and then putting aggregation pheromone (2-undecyloxy-1-ethanol) of the Monochamus alternatus into a slow release bag (low-density polyethylene), wherein the specific method refers to the patent of 'a Monochamus alternatus attractant and a using method thereof' (patent grant number: ZL 201610905301.8). Other embodiments are as above.

Table 4 monochamus alternatus attractant and solar light source examples (zhejiang linan, 2019, 7.1-7.14, N ═ 5)

The results of example 4 show that the combination of monochamus alternatus attractant and solar light source is more significant than the attractant alone or the solar light source alone. Wherein the number C is that the attractant is used together with the 365-370nm light source, the trapping effect is improved by 40.70 percent compared with that of the sole attractant of the number A, and the trapping effect is improved by 4.48 times compared with that of the 365-370nm light source of the number B. In addition, it is noted that the attractant used in combination with the light source shows a different rule from the individual light source test examples, wherein the attractant with the number E has the highest trapping amount at 380-.

Example 5

Trapping tests were conducted on a new town and a cave-bridge town in Fuyang city, Zhejiang province. Plant source pheromones (a-pinene, turpentine, ethanol, guaiacol and the like) are mixed according to a certain proportion and then put into a slow release bottle (low-density polyethylene), and then monochamus alternatus gathering pheromone (2-undecyloxy-1-ethanol) is put into a slow release bag (low-density polyethylene). 5 traps are arranged in each formula and are randomly distributed, and the interval between every two traps is 30-40 m. The trapping results were tested weekly starting at the beginning of 5 months in 2015 and 2016 and continuing until the end of 8 months. This time was just the major period of monochamus alternatus imago activity, and the number of monochamus alternatus lured per trap was recorded. The following test methods were the same as above.

Table 5 different dose trials of aggregation pheromones (zhejiang rich yang xindeng 2015, 5.10-6.14, N ═ 5)

The results of example 5 show that different additive amounts of aggregation pheromone 2-undecyloxy-1-ethanol have a significant effect on the trapping results, wherein the trapping effect of formula 4 with the content of 50 μ l is the highest, and then formula 5 with the content of 100 μ l is the lowest, and the difference is very significant, which shows that aggregation pheromone is a very important substance in Monochamus alternatus attractant, and the trapping effect can be significantly increased under a certain additive amount.

Example 6

TABLE 6 different terpene materials and burn material tests (Zhejiang Fuyang Xinden 2015,6.16-7.21, N ═ 5)

In the patent of Dengjiayu, etc., the adult Monochamus alternatus attractant and the use thereof (patent number: ZL201210557269.0), the invention discloses the Monochamus alternatus attractant comprises the following components of α -pinene 66.625-76.25%, β -pinene 3.75-13.375% and 20% of absolute ethyl alcohol by volume percentage of a plant-derived attractant, and the dosage of aggregation pheromone 2-undecyloxy-1-ethyl alcohol is 20 mg/induced core.

Zhang Fei Lianna et al patent entitled adult monochamus alternatus attractant (patent number: ZL201110269468.7) discloses that the attractant consists of aggregation pheromone and turpentine with the volume ratio of 1: 200-. The plant source pheromone and the monochamus alternatus gathering pheromone are mixed, a plastic slow-release bag releasing technology is adopted, an effective synergist is not available in the formula, the trapping effect is influenced, the gathering pheromone and turpentine are mixed together and released through the slow-release bag, small molecular substances are volatilized firstly, large molecular substances are volatilized later, the proportion of the formula at the later stage is easy to be seriously unbalanced, and the trapping effect is reduced; in addition, the lasting period of the technology is too short, and is only about 15 days.

The results of example 6 show that, firstly, in formulations 2 and 3, terpene substances such as β -pinene and camphene were added to α -pinene in formulation 1, respectively, but the results inhibited the trapping effect of monochamus alternatus hope, so α -pinene was the most preferable terpene substance and no other pinene substance should be added.

Secondly, a certain amount of guaiacol and 4-methyl guaiacol are added into the formulas 5,6, 7 and 8 respectively based on the formulas 1 and 2, and the trapping result shows that after the guaiacol and the 4-methyl guaiacol are added, the increase rate is remarkably improved compared with the original formula, and reaches 9.3% -18.8%, wherein the increase rate of the formula 6 based on the original formula 4 is 15.8%, and the highest trapping effect is shown. Guaiacol and 4-methyl guaiacol are volatile substances generated after burning of pine trees, which shows that the burning substances have good synergistic effect on original terpene substances and fermentation substances and are important synergistic substances.

Finally, both formula 5 containing turpentine and a fire material and formula 6 containing α -pinene and a fire material showed the best trapping effect, with formula 6 being slightly better than formula 5.

Example 7

TABLE 7 different dosage test of terpenes and fermented substances (Zhejiang Fuyang Kongqiao 2015, 5.10-6.14, N ═ 5)

The results of example 7 show that different dosages of terpene materials and fermentation materials have a significant effect on the trapping results, wherein the trapping effect is the highest when the ratio of the turpentine and ethanol in formula 3 is 3:1, and the worst when the ratio is 1:1, but the trapping effects of formulas 1-5 with ethanol are significantly higher than that of formula 6 without ethanol by 2.5 times, and the difference is significant, so that ethanol is an important synergistic material, and the optimal ratio of the turpentine to ethanol is 3: 1.

Example 8

Table 8 sustained release material tests of different thicknesses (zhejiang fuyang tunnel, 2016,6.10-7.23, N ═ 5)

Remarking: the attractant is prepared from 135ml of turpentine, 45ml of ethanol, 10ml of guaiacol, 10ml of 4-methyl guaiacol and 50 mul of 2-undecyloxy-1-ethanol.

The results of example 8 show that different thickness of the slow release bottle and the slow release bag have a significant effect on the trapping results, with the treatment 2 of the slow release bottle with a wall thickness of 0.40mm and the slow release bag with a wall thickness of 0.08mm having the highest trapping effect, significantly higher than the other formulations.

Example 9

TABLE 9 different kinds of sustained release technical test (Zhejiang Fuyang Xinden, 2016,6.19-8.17, N ═ 5, head/trap)

Remarking: the attractant is prepared from 135ml of turpentine, 45ml of ethanol, 10ml of guaiacol, 10ml of 4-methyl guaiacol and 50 mul of 2-undecyloxy-1-ethanol. The width of the slow release bottle is 6cm, and the height of the slow release bottle is 12 cm; the width of the slow release bag is 8cm, and the height of the slow release bag is 10 cm; the bottle cap is internally provided with a radial raised line with the width of 0.6mm and the height of 0.6 mm.

The results of example 9 show that treatment 4 with radial caps showed the highest trapping effect, which is 1.52 times that of treatment 3 without radial caps, because the radial lines with protrusions are designed at the bottom of the radial caps, which can regulate the airflow and the volatilization amount of pheromone, thereby improving the trapping effect. The trapping effects of the treatment 1 of releasing the aggregation pheromone by using a rubber plug, the treatment 2 of only using a sustained-release bag and the formula 5 of a common plastic bottle (high-density polyethylene) are remarkably lower than those of the treatment 3 and the treatment 4 of using the sustained-release bottle and the sustained-release bag.

From the lasting period, the treatment 4 with the radial bottle cap, the treatment 3 with the slow release bottle and the slow release bag and the treatment 1 with the slow release bottle and the rubber plug all show relatively stable lasting period which basically reaches about 2 months; the trapping effect was significantly reduced at week 5 in treatment 5 with the slow release bag using a common plastic bottle, and particularly, the treatment 2 with the slow release bag alone showed a tendency of a reduction in effect at week 4, so that the release from the common plastic bottle through the orifice and the release from the slow release bag alone could not reach a stable 2-month duration.
