Description
Technical Field
The invention relates to the technical field of forestry disease and pest control, in particular to a monochamus alternatus trapping agent and a preparation method thereof.
Background
Monochamus alternatus is a large pest in forestry and mainly harms red pine, Chinese red pine, fir, spruce, cedar, larch and the like. The monochamus alternatus hope mainly invades after trees are weakened to cause withering and death of a large number of trees, and the monochamus alternatus hope can also carry and spread the pine wood nematode disease to cause death of a large number of trees. Therefore, the prevention and treatment of Monochamus alternatus is especially necessary.
At present, the physical prevention and control, the biological prevention and control and the like are mainly used for preventing and controlling the monochamus alternatus disease, a monochamus alternatus trapping device is arranged, natural enemies of monochamus alternatus are put in the monochamus alternatus trapping device, and researches on monochamus alternatus trapping agents are few. In the current research, on one hand, host particles are mainly adopted for extraction, and extracts are made into attractants for attracting and catching, but the attractants are mainly induced into the catching by utilizing the fragrance components favored by Monochamus alternatus, the attractants depend on a trapping device seriously, and great device equipment is consumed, so that the disease and pest control in forest areas is difficult to popularize, on the other hand, the attractants with attracting and killing effects are also prepared by mixing pesticides and attracting components together, but the odor of the attractants can be influenced by the odor of the pesticides after the compounds are simply mixed, so that the attracting effect is poor. Therefore, it is important to design a trapping and killing dual-purpose trapping agent.
Disclosure of Invention
The invention overcomes the technical problems that the trapping agent in the prior art depends heavily on a trapping device, needs great equipment and has poor trapping effect of the trapping and killing combined trapping agent, and provides the Monochamus alternatus trapping agent and the preparation method thereof.
In order to solve the problems, the invention adopts the following technical scheme:
the monochamus alternatus trapping agent comprises a trapping core and a trapping layer; the trapping and killing core is coated with a film; an attracting layer is arranged on the film; the trapping core is prepared from the following raw materials in parts by mass: 100 parts of pine powder, 0.01-0.1 part of pesticide, 1-2 parts of rosin and 10-20 parts of 60% ethanol aqueous solution; the attraction layer is prepared from the following raw materials: 1-3 parts of pine cone extract, 10-20 parts of ethanol, 1-5 parts of acetone powder and 10-20 parts of pine fermentation product.
Further, the pine cone extract is prepared by the following method: crushing the pine cones, putting the crushed pine cones into a distillation kettle, introducing steam for heating, distilling at 120-140 ℃, distilling essential oil of the pine cones and the steam together, condensing and separating to obtain crude extract of the pine cones, dissolving the crude extract of the pine cones with ethanol, and drying with anhydrous sodium sulfate to obtain the pine cone extract.
Further, the pine tree powder is sieved by a 200-mesh sieve.
Further, the film is prepared from the following raw materials in parts by mass: corn starch 5%, glycerin 4%, sorbitol 1%, xylitol 1%, and the balance water.
Further, the pesticide is imidacloprid or thiacloprid.
Further, the pine powder is prepared from wood of the affected part of Monochamus alternatus.
Further, the pine wood fermentation product is prepared by the following method: pulverizing pine, adjusting the water content to 15-20%, adding one or more of Paecilomyces strains, Fusarium strains and erythrorhizobium strains, and fermenting for 3-5 days.
The invention also aims to protect the preparation method of the monochamus alternatus trapping agent, which comprises the following steps:
s1 preparation of the trapping core: dissolving rosin in 60% ethanol water solution, adding into pine tree powder, stirring, pressing into pine tree granule, diluting pesticide, and spraying into pine tree granule; the dilution times of the pesticide are determined according to different drug requirements;
s2 coating: preparing corn starch and water into a mixed solution according to a certain proportion, heating for pre-gelatinization, adding glycerol, sorbitol and xylitol according to a certain proportion, uniformly stirring to form a slurry, mixing and stirring the slurry and the pine tree particles obtained in S1 to uniformly coat a layer of slurry on the surfaces of the pine tree particles, drying to form a film on the surfaces of the pine tree particles, and mixing and stirring the dried pine tree particles and the slurry twice to coat a layer of slurry on the pine tree particles for later use;
s3: dissolving the strobilus Pini extract in ethanol and acetone, adding the fermented product of pine, and stirring; and mixing the pine tree particles obtained in the step S2 with the pine tree fermentation product in proportion, and drying at 60 ℃ to prepare the trapping agent.
Compared with the prior art, the invention has the following beneficial effects:
(1) in the existing researches, the parts invaded by monochamus alternatus hope are mainly tree trunks, and the researched trapping agent is also obtained from pine branches, but the inventor finds that monochamus alternatus hope does not invade pine cones in the daily cultivation and management process, and unexpectedly finds that the extract obtained by the extraction of the application has a trapping effect on monochamus alternatus hope, and the trapping effect is outstanding and higher than that of some existing chemical attractants when the research and the utilization of pine cones are carried out.
(2) The trapping agent comprises a trapping core, a trapping layer and a film; the attraction layer contains pine fermentation products and pine cone extracts, wherein acetone and ethanol are auxiliary agents, the pine fermentation products can be used as pine cone extract carriers to delay volatilization of the pine cone extracts and prolong attraction time, on the other hand, the pine fermentation products can be used as monochamus alternatus hosts, the monochamus alternatus inhabits on an attractant after being attracted by the attraction layer, in the lodging process, when the monochamus alternatus further eats the attraction agent, the thin film is damaged, and the attraction core can kill the monochamus alternatus.
(3) The film is made of starch, so that the attracting layer and the attracting and killing core can be isolated, the odor of the insecticide is prevented from interfering with the attracting components, and the effect of attracting the monochamus alternatus hope is further influenced.

Forest attraction experiment:
the test land is arranged in a stand-alone stand forest land of a seven-slope forest land in south-ning-Guangxi city, 750 mu of masson pine is planted in the forest land, the density is 65 plants/mu, and the test time is 5 months and 1 day in 2021 year to 6 months and 1 day in 2021 year. Examples 1-3 and controls 1-8 each experimental group was provided with 40 traps spaced 50 meters apart in the same experimental group, with the traps spaced more than 500 meters apart in different experimental groups to avoid the attractant interaction between the different experimental groups. The traps were hung with iron wires from a trunk having a height of 120cm, and were grouped according to the test, and the traps were filled with the trapping agents of examples 1 to 3 and controls 1 to 7, respectively. The condition of the adults in the traps was counted every 5 days, and the attracting results of each trap were averaged as shown in the following table 1.
Description of the test:
1. in the test, the pine-related raw materials such as pine and pine cone used in examples 1 to 3 and control groups 1 to 7 were obtained from pinus massoniana planted in the stand-alone forest of the heptaslope forest of south-China, Guangxi.
2. In order to avoid the trapping effect of the trap on the monochamus alternatus, the traps adopted in the test have no trapping effect, namely the light source of the existing traps is turned off.
TABLE 1
(Note: the "others" in Table 1 indicate pests of the family Carniidae other than Monochamus alternatus)
As is clear from Table 1, the trapping agent of examples 1 to 3 had the best trapping effect, and the technical effect of the present application was best described. On the other hand, the effect of the control group 1 was found to be that pine had a certain attracting effect to Monochamus alternatus after fermentation, but the effect was not good. As is clear from comparison of the control group 2 with the example 2, the pine cone added with the Paecilomyces sp, the Fusarium sp and the erythromyces sp does not have the luring effect on monochamus alternatus after being fermented for 3 days. The effect of the control group 3 shows that the pine cone extract also has a good attracting effect, but when used alone, the attracting time is not long and the attracting effect is poor. The attracting effect of the control group 4 and the control group 5 was not as good as that of the control group 3, and was not as good as that of examples 1 to 3, and it was found that the effect of extraction of the strobilus Pini extract obtained by distillation at different temperatures was different, and this was probably due to the preference of the volatile component extracted by Monochamus alternatus of the present application. The control group 6 had a certain attracting effect, although the effect was not as good as that of example 1, the control group 6 also had a certain attracting effect, indicating that the substance obtained by the same method also had a good attracting effect, but the effect was significantly different, probably because the ingredients of pine and pine cone were different, and even if the same method was used, the extracted ingredients were different, and the effect was different. In contrast, in the control group 7, the ultrasonic extraction was performed using an 80% ethanol solution as a solvent, and the extracted components may not be favored by Monochamus alternatus, so that the attracting effect was poor. The control group 8 is an attractant in the prior art, and the effect of the attractants in the embodiments 1 to 3 is better than that of the control group 8, which shows that the attractant of the application has better attraction effect than that of the attractant of the chemical formula in the prior art.
The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
