Abstract
The invention relates to a method for simply and efficiently utilizing predatory mites to prevent and control strawberry tetranychus mites. The method for preventing and controlling strawberry tetranychus mites through combining polyphagous predatory mites and phyoseiulus persimilis is specifically characterized in that the polyphagous predatory mites and the phyoseiulus persimilis are released for continuous 3 months or 4 months during 4 months from December of the current year to March of the next year. The invention provides the method for utilizing polyphagous predatory mites and phyoseiulus persimilis continuously in each month for the first time; a characteristic that the hunting capacity of the polyphagous predatory mites is stronger than that of the phyoseiulus persimilis at a low temperature condition is effectively combined with high efficiency of preventing and controlling the tetranychus mites by the phyoseiulus persimilis, so that relatively good prevention and control effects are realized, and a condition that the strawberry tetranychus mites cannot be prevented and controlled through independently utilizing the polyphagous predatory mites or the phyoseiulus persimilis can be solved; and the method is also simple to operate, is easily accepted by farmers and can achieve the effect of efficiently preventing and controlling the strawberry tetranychus mites without the need of investigating conditions of the tetranychus mites in advance and mechanically and continuously utilizing the predatory mites.
Description
Technical field
The present invention relates to a kind of method that utilization Predatory Mites simply efficiently prevent and treat strawberry tetranychid, belong to the life of modern agriculture insect
Thing prevention and control field.
Technical background
Predatory Mites are the Important Natural Enemies of preventing and treating strawberry tetranychid.
Personnel's overwhelming majority of domestic plantation strawberry is all the elderly at present, and in these people, the overwhelming majority does not see leaf again
A situation arises or be unable to the good tetranychid of accurate assurance a situation arises for mite, thus can not accurately the suitable time, with suitable amount and
Control of Pest Mites is gone down by suitable kind.Here particularly to should be mentioned that existing prevention and controls are all partial to suit the remedy to the case anti-
Control method, a situation arises if plant personnel is not easy to find in time tetranychid just easily misses the preventing and treating time, even results in total crop failure.
In actual production, strawberry tetranychid has a lot of influence factors, has plenty of Strawberry Seedlings and carries, has plenty of soil
In, being also possible to of having be anthropochory or extraneous incoming etc., concrete time of origin is not fixed.Sometimes in November or December or
January does not just find the generation of tetranychid at all, but but breaks out suddenly 2 months or March or April；In this case traditional
Preventative release cannot solve problem, need to carry out the release of preventing and treating property, good preventing and treating property release is it is necessary to investigate with sufficient
It is foundation, or even the complicated factor such as combination temperature, illumination, this is to be difficult to hold, especially very for strawberry cultivating person
In the case that many people are not easily seen tetranychid.And existing prevention and controls are less demanding to continuous release Predatory Mites, do not connect
Continuous release will do different releases according to the different situations of tetranychid, hold bad degree, be still the problem that can't resolve, cannot realize
Preferably prevention effect, even if continuously release Predatory Mites also tend to be the release of single variety, this is difficult to reach preferably prevents
Effect.
To sum up, the existing method using predation acarid control strawberry leaves mite, to the tetranychid investigation that a situation arises and grasp, leaf
Mite quantity requires compare high, very difficult power of a test with release tech with the control of amount with distribution, the selection of Predatory Mites, when grasping bad
Between not only cost can increase but also be unable to reach the expected purpose controlling tetranychid with amount.In addition, the erratic behavior, very that tetranychid occurs
Many growers are not easy to find that tetranychid leads to difficulty of prevention and cure to increase earlier.Further, existing tradition prevention and controls are to suit the remedy to the case,
Do different countermeasures according to different situations, but a situation arises, misses the preventing and treating time if tetranychid is not known in grasp, is extremely difficult to
Expected purpose, but actually existing numerous growers spray investigation out of question tetranychid is but very difficult, often do not see or
Invisible.
Based on existing Predatory Mites method for releasing to associated specifications height, need to carry out the work such as investigation release, and plant
Plant person does not possess this condition or ability it is therefore desirable to one kind is simple, efficient, grower is easy-to-use preys on acarid control strawberry
The method of tetranychid.
Content of the invention
It is an object of the invention to provide a kind of simple, efficient, method of peasant household predation acarid control strawberry leaves mite easily,
Present method solves most growers are not easy to investigate a difficult problem for Predatory Mites, solve peasant household's assurance bad preventing and treating opportunity
Problem, regardless of whether investigation, accurately whether, preventive effect is more than 90%, and under the conditions of equal consumption, appoints than being used alone for investigation
A kind of what Predatory Mites preventive effect is all good.
Method one：Prevent and treat the method for operating of strawberry tetranychid, tool using polyphagy Predatory Mites, Phyloseiulus nersimilis combined continuous
Body refers to before November conventionally to prevent or preventing and treating strawberry red spider, has crossed drug effect safe period or previous medication at least
Mortal injury will not be produced to the polyphagy Predatory Mites on 50% or Phyloseiulus nersimilis, from November backward to March in the coming year
5 months strawberry cultivating phases in, not only continuous 4 months or 5 months monthly at least release polyphagy Predatory Mites of 1 time, Er Qielian
The Phyloseiulus nersimilis monthly at least discharging 1 time in continuous 2 months or 3 months or 4 months or 5 months；Have or not before release and carry out tetranychid
Investigation or whether be found tetranychid or whether can distinguish tetranychid occur serious, all can use this method；Polyphagy is preyed on
Mite and Phyloseiulus nersimilis separate Different Package release or both discharge together with a packaging；Monthly polyphagy Predatory Mites
Consumption is 2.5 ten thousand/mu -25 ten thousand/mu, between preferably 100,000/mu -15 ten thousand/mu, the using method of polyphagy Predatory Mites
It is every row or every furrow strawberry is intended to be discharged into, described polyphagy Predatory Mites refer to the other Phytoseiidaes in addition to Phyloseiulus nersimilis
In mite class；Various polyphagy Predatory Mites are used alone or two kinds and combination of the above use, preferably small new neoseiulus californicus or California
The group of newly little peaceful mite and other Predatory Mites be combined in 3 months strawberry cultivating phases in January in November to the coming year then at least using 1 time plus
The newly little peaceful mite in state, small new neoseiulus californicus and other polyphagy Predatory Mites separately pack or together with pack；Monthly Chilean little plant
The consumption of peaceful mite is 1000/mu -2.5 ten thousand/mu, preferably 2000/mu -1 ten thousand/mu, the user of Phyloseiulus nersimilis
Method is preferentially to be discharged into the region being found tetranychid, has been discharged into tetranychid region without discovery tetranychid or Phyloseiulus nersimilis
Still there is residue afterwards, then dispersion is discharged on strawberry, preferably every 1-10 furrow or row strawberry at least discharge the little plant of Chile of 1 point
Peaceful mite；Monthly polyphagy Predatory Mites and the total volume of Phyloseiulus nersimilis are less than 37.5 ten thousand/mu；Polyphagy Predatory Mites with
Whether Phyloseiulus nersimilis release time is on the same day, both release time intervals be less than front or rear 30 days, preferably not
More than 15 days.
The innovative point of this method is：This method proposes one kind first and simply efficiently prevents and treats in greenhouse, booth, spring and autumn canopy
The method of strawberry tetranychid, the method focus on continuous release, continuous prevent and treat, tetranychid that Strawberry Seedlings carry can not only be solved and can also
Prevention or the unexpected tetranychid occurring of preventing and treating, thus be prevented effectively from because not finding in time to prevent and treat the loss that tetranychid brings in time.?
The strawberry cultivating phase of continuous 5 months, popularization and application this method prevents and treats strawberry tetranychid, and not only comparing other any methods all more has
Effect, and compare and be used alone polyphagy Predatory Mites or Phyloseiulus nersimilis, more can ensure that different situations, zones of different, difference
Preventive effect under the tetranychid extent of injury, different temperatures, this is because some situations individually be can't resolve with California, individually with Chile
Can't resolve, both combine and are more beneficial for solving.
Compared with existing tradition prevention and controls, this method does not differentiate between preventative release or slight hazard or serious harm feelings
Release under condition, but continuously use polyphagy Predatory Mites and Phytoseiulus Persimilis strawberry tetranychid, to numerous growers
Speech, the probability ratio not only reaching preferable preventive effect is used alone Phyloseiulus nersimilis or polyphagy Predatory Mites are high, and no matter has or not
Carry out tetranychid investigation, whether be found tetranychid, whether can distinguish tetranychid occur serious, apply this method be attained by very
Good preventive effect, it is to avoid can not find in time to prevent and treat the risk of tetranychid in time.
Polyphagy Predatory Mites and the use in conjunction of Phyloseiulus nersimilis, are more suitable for China's strawberry cultivating climatic environment, are us
State prevents and treats the optimal and the most efficient prevention and controls of strawberry leaves mite, is also all at present sides using predation acarid control strawberry leaves mite
In method, grower is easiest to the method operating and reaching more preferable preventive effect, and preventive effect is more more longlasting than individually with a certain kind.
From March in November then to the coming year, the strawberry cultivating phase of 5 months, strawberry will experience prolonged cold long term high temperature, drastically
Low temperature drastically high temperature, day and night temperature big, continuously cloudy day or haze sky, residues of pesticides because weather reason extend the problems such as, polyphagy
Predatory Mites and the use in conjunction of Phyloseiulus nersimilis, can be complementary, and applicant has been surprisingly found that polyphagy Predatory Mites, and (for example California is new
Little peaceful mite, the newly little peaceful mite of Pasteur, Tianjin river amblyseius as predatory mite, Si Shi amblyseius as predatory mite, amblyseius cucumeris oudeman) in 10 DEG C or 9 DEG C or 8 DEG C of morning and evening low temperature
Or 7 DEG C or 6 DEG C or less than 5 DEG C also movable predation tetranychids, or stronger than Phyloseiulus nersimilis prey ability under cryogenic conditions, this
Point just compensate for the defect of less predation under Phyloseiulus nersimilis low temperature, and polyphagy Predatory Mites can be caught under cryogenic
Food, the state reducing tetranychid population number or keeping no tetranychid, thus being conducive to the prevention and control of tetranychid, and under the conditions of 18 DEG C -28 DEG C,
Phyloseiulus nersimilis are active by force, compare polyphagy Predatory Mites spreads soon, and therefore both are more preferable with reference to effect meeting.In addition, in prey
Under the conditions of shortage, Phyloseiulus nersimilis are alternatively arranged as polyphagy Predatory Mites food, more in beneficial to polyphagy Predatory Mites colonize with
The prevention and control of tetranychid.
Compared with number of patent application 201610139789.8, the present invention is monthly lower using Predatory Mites total amount, and preventive effect is more
Good, more than 90%, and continuous 4 months or 5 months every monthly release polyphagy Predatory Mites, continuous 3 months or 4 months or 5
All discharge Phyloseiulus nersimilis within individual month, according to documents Predatory Mites release conditions, documents are to start to use from October, though
It is so 4 months, but to January cut-off, and this patent is then to end to 2 months, and at least pacified using little plant of Chile of 1 month
Mite, preferably January in November then to the coming year 3 months strawberry cultivating phases at least using the small new neoseiulus californicus of 1 time.
To sum up, although this method uses the amount of Predatory Mites higher, preventative release need not be distinguished or slight hazard is released
Put or serious harm release, a situation arises and distribution just can reach more preferable preventive effect, especially also can to investigate tetranychid in advance
Small new neoseiulus californicus and the combining of Phyloseiulus nersimilis, if according to this method can effective control strawberry tetranychid generation,
Preventive effect more than 90%, more accurately suit the remedy to the case and continuously use, then prevent by the distribution in conjunction with the investigation of tetranychid, grasp tetranychid
Efficiency reaches 100%.
Method two：It is to combine preventing and treating greenhouse, booth, spring using bayesian Olympic mite, small new neoseiulus californicus, Phyloseiulus nersimilis
The method of autumn canopy strawberry tetranychid, method of operating specifically refers to conventionally prevent before November or preventing and treating strawberry spider
Spider, has crossed drug effect safe period or previous medication and at least the small new neoseiulus californicus on 50% or Phyloseiulus nersimilis will not have been produced and cause
During life injury, from November backward within 5 months strawberry cultivating phases in March in the coming year, not only continuous 3 months or 4 months or 5
The moon monthly at least the release bayesian Olympic mite of 1 time and small new neoseiulus californicus, and continuous 3 months or 4 months or 5 months monthly extremely
Discharge the Phyloseiulus nersimilis of 1 time less；Have or not before release and carry out tetranychid investigation or whether be found tetranychid or whether can distinguish leaf
Mite generation is serious, all can use this method；Bayesian Olympic mite, small new neoseiulus californicus, Phyloseiulus nersimilis separately difference
Packaging discharges or discharges together in a packaging；Monthly consumption >=1 of bayesian Olympic mite/mu, preferably >=50,000/mu；Plus
The consumption of the newly little peaceful mite in state be 50,000/mu -25 ten thousand/mu, between preferably 100,000/mu -15 ten thousand/mu, bayesian Olympic mite with
The using method of small new neoseiulus californicus is every row or every furrow strawberry is intended to be discharged into；Small new neoseiulus californicus be used alone or with other
Predatory Mites breed combination uses；Monthly the consumption of Phyloseiulus nersimilis is 1000/mu -3 ten thousand/mu, preferably 2000/mu -1
Ten thousand/mu, the using method of Phyloseiulus nersimilis is preferentially to be discharged into the region being found tetranychid, without find tetranychid or
Phyloseiulus nersimilis still have residue after being discharged into tetranychid region, then dispersion is discharged on strawberry, preferably every 1-10 furrow or
Row strawberry at least discharges the Phyloseiulus nersimilis of 1 point；Monthly the total volume of small new neoseiulus californicus and Phyloseiulus nersimilis is not
More than 350,000/mu；Whether small new neoseiulus californicus and Phyloseiulus nersimilis release time are on the same day, both release times
Interval was less than front or rear 30 days, preferably more than 15 days.
In addition to innovative point described in method one, another innovative point is this method：No matter air humidity be less than 50% or etc.
In or be higher than 50%, it is numerous that the addition of bayesian Olympic mite can be conducive to population in strawberry for the small new neoseiulus californicus to colonize expansion,
From March in November to the coming year, especially northern winter air humidity is low, and in the case that air humidity is low, small new neoseiulus californicus take food shellfish
Family name Olympic mite, is conducive to small new neoseiulus californicus to spend the adverse circumstance phase, the survival of small new neoseiulus californicus is conducive to it under optimum conditions
Play the effect preferably preventing and treating strawberry tetranychid, thus the expansion not only contributing under small new neoseiulus californicus low temperature is numerous, also help
Reduce tetranychid worm radix, be conducive to the prevention and control of whole strawberry cultivating phase；It is new that the addition of bayesian Olympic mite also helps minimizing California
The predation to Phyloseiulus nersimilis under low temperature or normal temperature or high temperature of little peaceful mite, in the case of Phyloseiulus nersimilis starvation, bayesian is difficult to understand
Woods mite is alternatively arranged as supplements, thus being conducive to the preventing and treating to strawberry tetranychid.
In addition, the unexpected addition finding bayesian Olympic mite, also help mitigation strawberry brown spot, bud blight, anthrax
Disease, droop, gray mold must endanger, and the addition of therefore bayesian Olympic mite not only contributes to tetranychid prevention and control and also can cure the disease, many at one stroke
Effect.
