Description
Technical field
The utility model belongs to agricultural technology field, specifically, is related to a kind of controlled-release device for being sustained volatile materials,
It can allow volatile materials to be discharged completely with even speed, it is possible to substantially completely discharge volatile materials therein.
Background technology
It is well known that the volatile chemical of low molecule amount is agriculturally not only having there is many purposes, there is also potential
Purposes, including using volatile chemical as the attractant and repellant for insect.In insect attractant
Sex pheromone is a kind of volatile chemical signal for being used to attract each other and send between the similar opposite sex, and insect polymerization letter
Breath element is typically then to be produced by the insect of a certain sex, plays a part of aggregation, aggregation pheromone can attract similar simultaneously
Male and female insects.In addition, also have other volatile materials such as methyl eugenol, raspberry ketone, zingiberone in insect attractant,
And these volatile materials are produced by plant originally, but it can attract using it for the male fruit fly eaten, and by this letter
Breath element, which is passed, to be changed to the attractive material of female fruit fly.
In addition, there is the volatile materials with avoidance effect, these volatile materials are included such as gaultherolin, it
While walking quickly and keeping away the insect brown paddy plant hopper on paddy rice, it is also equipped with luring its natural enemy i.e. effect of egg parasitoidses Anagrus nilaparvatae.
In addition, historically, be taken from plant or some volatile chemicals similar to plant, when being discharged into air
When middle, there is good avoidance effect to mosquito.These volatile materials include but is not limited to citronellal, linalool, geraniol.
Thus, some important insect pests are controlled using the volatile materials of safety have become it is a kind of highly effective
Means, it is more and more important for environment and the producer.
Exchanged in addition, between plant chemical signal can be discharged by the volatile compound with bioactivity,
Such as plant can secrete the activity of methyl jasmonate early warning other crops on insect on plant, and these chemical signals are around
A kind of chemical defence is established between plant, some chemical substances for being unfavorable for insect digestion are secreted.Furthermore, these are planted
Chemical signal is also possible to influence the growth result of some crops between thing, for example, the chemical substance of certain plants secretion can strengthen
The bright-coloured degree of apple color.
However, due to volatile chemical easily rapid volatilization in atmosphere, so a kind of controlled release must be placed it in
Volatilized in device, it is permanently effective to ensure their slow releases in a long time.
It is well known in the prior art to have solid kind controlled-release device, i.e. volatile chemical is blended in by wax or high score
In the solid kind controlled-release device that sub- polymeric material is made, the lure that such as wax stone or glue head are done, this kind of product makes very simple
It is single, but rate of release it cannot be guaranteed that, its rate of release and the speed and concentration of the volatile chemical volatilization in controlled-release device
There are much relations, when the volatile species concentration reduction in wax stone or glue head lure, rate of volatilization can also be reduced therewith, be entered
And impact effect.Although this controlled-release device is simple, the significant wastage of volatile chemical is caused.Because waving at the beginning
Volatile material release ground is too fast too many, and remaining volatilizable chemical substance just becomes very little because of concentration step-down quickly.This feelings
It is not good that shape causes the effect reached.Especially reached when using a large amount of expensive insect sex pheromones by Insect pest suppression technology
When preventing and treating purpose, this kind of volatile compound is expensive, and the waste of early stage causes cost very high.
In addition, containing the glue head lure of sex pheromone as the controlled-release device for the purpose of luring, lure release concentration mistake
During high sex pheromone, targeted insect may be played a part of walking quickly and keeping away rather than attracted；And concentration it is too low when, then can not be to mesh
Mark insect has enough attracting abilities.Thus, both of which is not suitable for trapping and killing as purpose practical application.Such control
Release device can not be precisely controlled to the volatile concentrations and speed of volatile materials.
It is well known in the prior art to also have storage class controlled-release device in addition to foregoing solid kind controlled-release device.Generally and
Speech, the control device that contained volatile materials can be discharged into close to zero is referred to as storing class controlled-release device.Existing difference
Some in the storage class controlled-release device of type have been commercialized.
A kind of extrusion tubulose controlled-release device is disclosed in United States Patent (USP) US No.4,600,146.Wherein, one is disclosed to squeeze
Go out the capillary release of formula, extruder injects pheromones while capillary is extruded, then cut-out sealing.The pipe of capillary
Chamber is narrow (diameter is usually 1 to 3 millimeter), if it is desired to filling capillary sky with pheromones again after normal temperature state, extrusion capillary
The frictional resistance produced during pipe can be very high, so that thinking that the way for being filled up completely with these full capillaries again after the extrusion can not be in life
Realized in production.In the production of actual industrial metaplasia, the injection of the extrusion and pheromones of capillary is to carry out simultaneously, is then carried out again
Cutting and sealing, filling information element means that pheromones have been exposed at a high temperature of molten plastic while capillary is extruded,
And to realize that the production process accurately filled is costly and troublesome poeration while extrusion.In addition, there is many hosts
Plant volatile or similar compound cannot be used for filling such capillary, because many of which Herbivore
The boiling point of compound is near or below the fusing point of plastics.Meanwhile, this capillary release cavity volume is limited.Host plant is waved
The use of hair property compound is generally more than the consumption of insect pheromone, thus this kind of compound is not suitable for hot filled capillary pipe.
United States Patent (USP) US No.4, disclose a kind of packed controlled-release device in 923,119, it use one and simply may be used
The packed release of release pheromone.The advantage of this release is low manufacture cost.In fact, they are to be adapted to be filled up completely with
Type.The shortcoming of this release is that wall is very thin, in general wall thickness about 0.01mm.Although this packed release is indoors
Show good in the laboratory environment of temperature control, but this kind of packed release containing pheromones easily goes out in the high environment of temperature
Existing pheromones largely promptly discharge, and thereby result in waste, influence its efficiency.
United States Patent (USP) US No.5, disclose a kind of capsule controlled-release device in 316,148, it specifically discloses a kind of vacuum
Capsule release.One side of the release is impermeable, and another side is that a kind of very thin film is constituted, releasably
Pheromones.This film used on orchestration of releasing inevitably runs into bag-shaped controlled-release device described above asking equally
Topic.
In addition, disclosing a kind of controlled-release device in German patent DE 3640880, it is equally blow-molded, and heat is filled out
Fill and be tightly connected.The composition of the controlled-release device is that one or two thin-walled capsule is arranged at top, and bottom also has one to contain information
The reserved cavity of element, upper thickness is 0.02-0.15 millimeters, passes through its upper film release pheromone.But because of bottom wall thickness,
This part of bottom pheromones can not be caused largely to remain in bottom and reserve chamber according to the predetermined normal release pheromone of speed
Body causes to waste.In addition the manufacturing cost of this release is higher.
In addition, foregoing lure is also that targeted insect is monitored and observed and predicted with pheromones, this technology
Existing history for many years.The purpose of monitoring, which is mainly, gathers certain insect in the generation in field, algebraically and population active situation.It is logical
Monitoring Data is crossed, farmer can understand target insect pest in time, and a situation arises, takes prophylactico-therapeutic measures in time when needed.Typically
In the case of, the quantity that monitoring lure is used is very little, for example：Using 1/10-20 mus, in this case, lure is only in prison
Play a part of luring in survey, the population quantity of target insect pest can't be influenceed and a situation arises.
However, in practical application, many insects can be reached anti-using a large amount of methods trapped and killed using aggregation pheromone
The effect controlled.But the pheromone dispenser used during trapping possesses the function of slow release long-acting, this point is actual for commercialization field
Using being all very important, otherwise frequently change lure and the substantial amounts of labour cost that causes can allow this trapping method because
The too high peasant of expense can not bear and can only rest on the stage observed and predicted.
Some important moth worms can also be prevented and treated with the method for trapping.Such as corn borer (Ostrinia
Furnacalis) and rice-stem borer (Chilo suppressalis), compared with above-mentioned large-scale insect, these moth worms
Only needing to seldom pheromones can just play a part of luring, and each lure only needs to the pheromones less than 0.2mg, and these
Pheromones are often sex pheromone.These sex pheromones have volatilization, and volatilization can attract similar male, allow this in atmosphere
A little sex pheromones, which can continue long-acting release, then to be needed sex pheromone being placed in the release for possess slow releasing function and could rise
To effect.
In general, the pheromones of small-sized moth worm are all the lures made by small rubber head to carry, though this method
So it has been used many years but still has had significant limitation.First, the lure being made of small rubber head carrying information element
Evaporation rate is unstable, equally at 25 DEG C, after half pheromones are released, the burst size meeting of pheromones in daily lure
Original half is reduced to, this means that the burst size of beginning is too high, and burst size below is inadequate, causes to waste.Its
Secondary, in addition to burst size is unstable, effective efficiency time of Rubber end lure is very short, is usually no more than one month, so
At least need every month to change once, then for insects such as preventing and treating striped rice borer, a Growing Season of Crops is accomplished by changing at least
6-7 times, not only increase cost, labour cost also can be very expensive, be completely unsuitable for commercially use and promote.Rubber end lure
The pheromones amount that limitation is also embodied in a Rubber end and can carried is very limited amount of, is volatilized when needing a large amount of other of mixing
During attraction of the property compound to strengthen main compound, the pheromones amount that Rubber end can be carried but because can not be effectively increased and
It is restricted.
Therefore, in the prior art in the urgent need to one kind can solve the problem that foregoing problems, both having realized makes volatile materials with complete
Uniform speed, which discharge and can reached, finally makes its controlled-release device remained that cannot not volatilize surplusly completely, and the controlled-release device again may be used
