Abstract
The invention relates to a preparing method for slow release pill grain agent of porous farina bristletail attractant. The method includes the steps of: (1) making the porous farina adsorbing bristletail attractant into different sized pill grains; (2) putting the prepared pill grains into high molecular compound solution of which the weight percentage is 5-10 percent and which can form polymer membrane, and soaking the pill grains in the cross linking agent saturated solution for 0-12 minutes to ensure that the polymer membrane is solidified fully, then taking the grains out for airing naturally. The method is easy to produce with low cost, and is applicable for industrially producing the bristletail attractant slow release agent which can effectively control the release speed.
Description
Technical field
The invention belongs to the preparation field of slowly-releasing pill preparation, particularly relate to the preparation of stephanoporate starch bark beetle attractant slow release ball granule preparion.
Background technology
Bark beetle has been one of injurious forest-insect of tool harm in the forest ecosystem in the global range, and in recent years along with the rapid increase of China's imported timber quantity, external bark beetle also enters China thereupon.Be the harm that prevents that bark beetle from bringing, the staff takes the means of trapping and killing on the one hand in forest, improve the quarantine effect of bark beetle on the other hand, stops external bark beetle to enter.
The trapping bark beetle is taked methods such as trapper release, trunk sprinkling and airplane spray mostly in the forest at present, target bark beetle epideictic pheromone, aggregation pheromone analog and aggregation pheromone inhibitor etc. are released in the forest ecosystem, but, in use increased the weight of the live load that sprays because this type of material has volatility; In addition, the attractant sample that in the forest bark beetle trapping occasion different, needs to have different rates of release, but the still incompetent at present spacetabs type bark beetle attractant commodity that satisfy under above-mentioned two kinds of occasion service conditions with the timber quarantine.
Summary of the invention
The invention provides a kind of preparation method of stephanoporate starch bark beetle attractant slow release ball granule preparion, but this method is produced the effectively bark beetle attractant slow release preparation of sustained release speed of simple and easy, with low cost suitability for industrialized production.
The preparation method of a kind of stephanoporate starch bark beetle attractant slow release ball granule preparion of the present invention may further comprise the steps:
(1) porous-starch is adsorbed the bark beetle attractant, make the pill of different sizes;
(2) pill that makes is put in the macromolecular compound solution of formed polymeric membrane that mass percent is 5%-10%; soaking 0-12min then in the crosslinking agent saturated solution fully solidifies polymeric membrane; take out, dry naturally to make bark beetle attractant pill sustained release preparation.
The pill of described different sizes, its diameter is 1.0cm, 1.5cm, 1.8cm.
Described macromolecular compound (as: polyvinyl alcohol), nontoxic, membrance casting condition is simple, and molecular backbone has more pendant hydroxyl groups.
Described crosslinking agent is inorganic acid (as: boric acid), can form polymer complex with the hydroxyl dehydration of macromolecular compound.
Porous-starch of the present invention has extraordinary absorption property, and inwall is had protective effect; These article wide material sources, cheap and easy to get; Process safety, nontoxic; Biodegradable, be widely used.
The present invention is by changing the preparation technology and the polymer complex membrane wrapping thickness of porous-starch bark beetle attractant pill sustained release preparation, can effectively regulate the rate of release of sustained release preparation, both can be used for forest trapping bark beetle, also can be used for the occasion of forest and timber quarantine; Process safety is nontoxic in addition, is widely used, and adaptability is strong.

Embodiment
The invention will be further elaborated below in conjunction with specific embodiment, should be understood that these embodiment only are used to the present invention is described and are not used in to limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalences fall within the application's appended claims institute restricted portion equally.
Embodiment 1
Make the pill that diameter is 1.0cm, 1.5cm, 1.8cm respectively after the bark beetle attractant of 150 order porous-starch and capacity evenly mixed, make bark beetle attractant pill individual layer sustained release preparation.
Embodiment 2
Make the pill that diameter is respectively 1.0cm, 1.5cm, 1.8cm after the bark beetle attractant of 150 order porous-starch and capacity evenly mixed, it is 5% can form in macromolecular compound (as: polyvinyl alcohol) solution of polymeric membrane that the pill that makes is put into mass percent concentration, soaking 10min then in crosslinking agent (as: boric acid) saturated solution fully solidifies polymeric membrane, take out, dry naturally to make the two sustained release preparations of bark beetle attractant pill.
Make the pill that diameter is respectively 1.0cm, 1.5cm, 1.8cm after the bark beetle attractant of 150 order porous-starch and capacity evenly mixed, it is 10% can form in macromolecular compound (as: polyvinyl alcohol) solution of polymeric membrane that the pill that makes is put into mass percent concentration, soaking 10min then in crosslinking agent (as: boric acid) saturated solution fully solidifies polymeric membrane, take out, dry naturally to make the two sustained release preparations of bark beetle attractant pill.
Embodiment 4
Make the pill that diameter is 1.5cm after the bark beetle attractant of 150 order porous-starch and capacity evenly mixed, it is 5% can form in macromolecular compound (as: polyvinyl alcohol) solution of polymeric membrane that the pill that makes is put into mass percent concentration, soaking 10min then in crosslinking agent (as: boric acid) saturated solution fully solidifies polymeric membrane, take out, dry naturally to make the two sustained release preparations of bark beetle attractant pill.On the Ba Xincai of test region yard trapper is set, the pill placement is lured be suspended on trapper top in the core ball, trapper discharges 120h continuously, and every 12h checks once, writes down the borer population of traping, and bark beetle is taken out.
Embodiment 5
Embodiment 1, embodiment 2, embodiment 3 prepared spacetabs type bark beetle attractant samples are carried out the release performance test under the unlimited condition of room temperature, the result as shown in Figure 1, 2, 3.Test result shows: bark beetle attractant pill sustained release preparation increases with pellet diameters, and its slow release effect increases; Increase with the macromolecular compound solution concentration that can form polymeric membrane, its slow release effect also increases.
Under the natural environment, the bark beetle attractant effect result of the test of carrying out on the Ba Xincai of test region yard as shown in Figure 4.The result shows that the two sustained release preparation trap effects within 1d of porous-starch bark beetle attractant pill are extremely remarkable, the sustainable 2d of excellent trap effect of this sustained release preparation.
