Utilize the new method and usage of amblyseius cucumeris oudeman as predation acarid control bamboo grove evil mite
Technical field: the present invention relates to a kind of operation technique that can be used for replacing the harmful mite natural enemy predation mite of chemical pesticide, particularly a kind of new method and usage that utilizes amblyseius cucumeris oudeman as predation acarid control bamboo grove evil mite.
At present, the generally generation of various agricultural crops evil mites (as two spotted spider mite, blister mite, tarsonemid, various flour mites etc.), the rampant big problem that become international that endangers, early tetranychid (two spotted spider mite) and trypetid, black peach aphid, rice borer, armored scale are classified as five major pests in the world, prevent and treat the target of administering with agricultural synthesis as the natural enemy of international joint research.Small worm becomes terrible disaster, be China in recent years in the rural area after the development trend, particularly China joined WTO of many insect pests, agricultural will be to be subjected to impacting one of maximum industry, agricultural byproducts will be faced with significant challenge, and wherein residue of pesticide are one of problem demanding prompt solutions.Produce pollution-free food, reduce environmental pollution, improve the ecological environment, caused the pay attention to day by day of various countries (at different levels) government and scientific research popularizing department.Insect of the present crops of China and evil mite still endanger seriously, but China tackles various harmful mites at present still based on chemical control, per season medication number of times such as strawberry, cotton, various booth vegetable, flowers, tea place, mushroom, white fungus, mushroom reach 5-8 time, the year medication number of times that has reaches 10-20 time, not only cause the severe contamination of atmosphere, waters or local area ecological, evil mite pesticide resistance also increases severely, and almost reaches the condition that pasts medical help.Utilizing useful mite class for natural enemy control pest mite class, is the optimal path of the current mite of control evil in the world.Wherein have abroad and mainly be used in the natural enemy of greenhouse as insect one thrips of control cucumber, capsicum as the amblyseius cucumeris oudeman (Amblyseius cucumeris) of preying on one of mite, generation and outburst with the prevention thrips, report as the harm of many food tarsonemids and Tetranychus urticae on the strawberry in effective control greenhouse, the report that harm takes place as the big Tanaka's of natural enemy control and prevention thrips is also arranged, but do not see amblyseius cucumeris oudeman as control and the report of preventing and treating the natural enemy application facet of multiple harmful mite on (hair) bamboo grove.In addition: well-known; bamboo, particularly mao bamboon are the important forest resources in southern china province; occupy very important effect in protection ecology, increase national income, Fujian Province is China mao bamboon main producing region, and mao bamboon and bamboo shoots are the important points of economic increase in mountain area, Fujian Province.Yet, the harmful mite kind of mao bamboo woods is many, along with the increase of people to mao bamboon development and use intensity, a large amount of mixed forests are transformed into pure bamboo grove, ground is cultivated multiple, applying pesticides etc., evil mite pesticide resistance increases severely, cause mao bamboon evil mite generally to be taken place, local even cause disaster, because the evil mite is got food harm at blade, destroyed the normal physiological and biochemical activity of mao bamboon, influence the accumulation of mao bamboon available nutrient, cause Zhushan County to decay, to local economy, ecology produces serious influence, thereby the research of biology of mao bamboon and other bamboo grove tetranychids and integrated control technique tackling key problem has caused the great attention of governments at all levels and functional department.
Because above reason; the purpose of this invention is to provide a kind of new method and usage that utilizes amblyseius cucumeris oudeman as predation acarid control bamboo grove evil mite; make and to have that control efficiency is good, the continuous and effective time long, can significantly reduce medication number of times and drug cost; reduce residue of pesticide; significantly improve output and the quality of (hair) bamboo output and bamboo shoots, favourable preserving the ecological environment.
The present invention realizes with following technical scheme: observe according to investigation and find, the harmful mite kind that comprises the bamboo grove of mao bamboon has multiple, comprise Nanjing Schizotetranychus, SchizotetranychusnanjingensisMaetYuan, Phyllostachys pubscens Mazel, bamboo thorn goitre mite and narrow nest Schizotetranychus etc., the applicant is through for many years arduous exploration, utilize spreading, spread and endangering of amblyseius cucumeris oudeman control (hair) bamboo grove evil mite, sum up the effective comprehensive control measures of a cover.What be worth emphasizing is: introduced the kind mite from external as the amblyseius cucumeris oudeman of one of predation mite first by the applicant, and artificial feed prescription of this predation mite and large scale artificial breeding's raising method (having applied for Chinese patent) have been succeeded in developing through arduous exploration for many years, through observational study, carry out the specification requirement that " controlling mite with mite " meets the biology integrated control of mao bamboon tetranychid in Zhushan County, because mao bamboon evil mite kind is many, kind Zhushan County's utilization predation mite must be easy to the large scale artificial breeding, this is one of important prerequisite, secondly, selected predation mite kind must be able to be climbed up the bamboo bar and be arrived the leaf of bamboo (comprising the bamboo hat top leaf of bamboo), could effectively control the harm of multiple harmful mite like this.For this reason, characteristics of the present invention be we be bold in innovation work out utilization at present in enormous quantities the amblyseius cucumeris oudeman produced of batch production promptly utilize amblyseius cucumeris oudeman (Amblyseiuscucumeris) to control and prevent and treat that multiple harmful mites such as Nanjing Schizotetranychus, SchizotetranychusnanjingensisMaetYuan, Phyllostachys pubscens Mazel, bamboo thorn goitre mite and narrow nest Schizotetranychus in (hair) bamboo grove endanger controls the new purposes of mite with mite as natural enemy as the new method and usage of predation acarid control bamboo grove evil mite.
Compared with the prior art, main innovate point of the present invention is to use amblyseius cucumeris oudeman to carry out " controlling mite with mite " first in bamboo grove, and this is new trial on the inside and outside biological control history of mao bamboon mountain country.Through constantly courageously research exploration for many years, obtain a large amount of experimental datas of five kinds of harmful mites of amblyseius cucumeris oudeman and mao bamboon predation reaction, autologous density functional response, disturbance reponse, numerical response etc. under different temperatures, damp condition, shown that amblyseius cucumeris oudeman is effective predator of mao bamboon evil mite.Carrying out mao bamboon tree crown test on the amblyseius cucumeris oudeman in Zhushan County, the result shows: discharging amblyseius cucumeris oudeman on the mao bamboon after 15-20 hour, this predation mite can be climbed up 12 meters high bamboo hat from 1 meter high bamboo bar, has proved that amblyseius cucumeris oudeman can spread in mao bamboo woods voluntarily.We once surplus Fujian Province 10 more than 10,000 mu of Zhushan County of a counties and cities discharge on a large scale the amblyseius cucumeris oudeman effect significantly, swept area reach 10 surplus ten thousand mu.Control mao bamboon evil mite effect reaches 85-95%, directly increases Hsinchu 97-110 ten thousand strains, increases by ten thousand kilograms of new bamboo shoot 269-300, directly increases by ten thousand yuan of output value 659-700.Compare experiment demonstration area and check plot " to control mite with mite "; discharge amblyseius cucumeris oudeman and can effectively control the population density of mao bamboon evil mite; reduced the harmfulness of harmful mite significantly; experiment Hsinchu, demonstration area output and eyebrow enclose and have significantly than the check plot that raising, strain rate of damage, blade rate of damage descend significantly; the continuous and effective time is long; medication number of times and cost have significantly been reduced; residue of pesticide have been reduced; significantly improved output and the quality (persticide residue minimizing) of upright bamboo amount of mao bamboon and bamboo shoots, also helped improvement and preserve the ecological environment.
Below in conjunction with concrete application example the present invention is described in further detail.The present invention also has following some technical characterictic when specifically practicing:
One, utilize amblyseius cucumeris oudeman as the harm of natural enemy control bamboo grove evil mite control the new purposes of mite with mite the time, the method step of its use comprises that (being that the mite evil breaks out early stage) takes place early stage the harmful mite in annual June to August in release period (time) grasp, the position that discharges amblyseius cucumeris oudeman is selected at overhead on (as 1.5 meters) the mao bamboon mobile jib more than 1 meter (can adopt the dedicated slow release to discharge), and the burst size grasp of every strain (hair) bamboo is at 300-500.
Two, utilize amblyseius cucumeris oudeman as the harm of natural enemy control bamboo grove evil mite control the new purposes of mite with mite the time, note carrying out chemoprevention (chemical control) integrated control, promptly in the heavy calamity generating region of (hair) bamboo grove evil mite, should use medicine on bamboo cavity injection chemical agent, ground, fertile measure relief evil mite population density just discharges amblyseius cucumeris oudeman when significantly descending and is advisable.
Three, utilize amblyseius cucumeris oudeman as natural enemy control bamboo grove evil mite control the new purposes of mite with mite the time, should reduce in the bamboo district that discharges the predation mite as far as possible and to cultivate multiple weeding number of times, keep shallow root system weeds, applying organic manure, and can suitably in pure bamboo grove, mix and hand over some forests, make the predation mite that good survive the winter summer place and bridging species be arranged, allow (hair) bamboo grove be in towards the sustainable eucyclic state of ecology.
