A kind of as predation mite--the rearing method of-amblyseius cucumeris oudeman
Technical field
The present invention relates to a kind of breeding technology that does harm to the natural enemy predation mite of mite, especially a kind of rearing method (comprising artificial feed prescription and industrialized producing technology flow process) as the amblyseius cucumeris oudeman of preying on mite.
Background technology
At present, the generally generation of various farmings, woods crop evil mite (comprising two spotted spider mite, blister mite, tarsonemid, flour mite), the harm that runs wild have become worldwide big problem, in nineteen sixty-five International Biological Programme (IBP) meeting held of Rome, ITA, tetranychid (two spotted spider mite) and trypetid, black peach aphid, rice borer, armored scale are classified as five major pests, as the natural enemy of international joint research and the target of agricultural synthesis improvement.It has been China's development trend of insect in the agricultural and forestry production in recent years that small worm becomes terrible disaster, for example the evil of the two spotted spider mite on cotton mite has risen to primary pest, national wheat belt is popularized in wheat red mite harm, the harm of paddy rice tarsonemid causes underproduction 30-60%, citrus red mite, blister mite are the important harmful mites in China citrus producing region, have a strong impact on the yield and quality of citrus, and annual agricultural chemicals access times in order to control are many, evil mite pesticide resistance increases severely, and has reached the condition that pasts medical help.The harmful mite kind of edible mushrooms such as mushroom, white fungus, mushroom is many, as flour mite, Pu mite, tarsonemid, not only gets the food mycelium, can also get the infanticide entity, causes crushing losses such as mashed bed, mashed kind; North matrimony vine, Chinese pine, southern bamboo grove, pine tree, city trees and shrubs, flowers, tea place, booth vegetable all are subjected to the harm of mite class in various degree.China crops evil mite is still based on chemical control at present.Strawberry, cotton, apple citrus, matrimony vine year medication number of times compete to reach 10-20 time, some edible mushrooms such as mushroom eat, white fungus, the per season medication of mushroom number of times reach 5-8 time, city trees and shrubs 5-6 time causes the severe contamination of atmosphere, waters, food, also has a strong impact on the yield and quality of product.China's tealeaves exports again and again in recent years and is obstructed, and major reason is exactly the dicofol severe overweight.Eliminating residue of pesticide, producing pollution-free food, reduce environmental pollution, improve environment for human survival is one of governments at all levels, the anxious problem to be solved of scientific research personnel.Therefore, use the biological control strategy, wherein to utilize useful mite class (predation mite) control pest mite class be the optimal path of the current mite of control evil in the world harm.China in the 70-80 age in Beijing, Jiangxi, Guangdong, provinces and cities utilize the predation mite (west is blind walk mite surplus the Shanghai etc. ten, the De Shi genus amblyseius berlese, the Nissl genus amblyseius berlese) control citrus, apple, cotton, two spotted spider mite on the crops such as eggplant, yellow tea mite obtains certain success on the tealeaves, but traditional predation mite artificial propagation method expense costliness, be chemical control 10-20 doubly, can not large-scale industrial production, its common method is to adopt pollen or plantation certain plants to raise two spotted spider mite, and then make feed with two spotted spider mite and raise the predation mite, a large amount of production difficulty are big, above-mentioned pollen cultivation and predation mite bag cultivating are supported method (two spotted spider mite breeding method) expense height, the worker employed in a plant nursery is big, cycle is long, can't need provide adequate prod by producing, China does not pass a test because of preying on mite artificial feed and propagation technique, therefore after entering the nineties, control mite biological control work with mite and still be difficult to carry out smoothly always.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of predation mite--rearing method (being artificial feed prescription and commercialization production technology) of-amblyseius cucumeris oudeman that is applicable to is provided.Make the predation mite a large amount of breedings of batch production to provide as required, have the cycle short, the worker employed in a plant nursery is few, expense is low, help producing nuisanceless agricultural byproducts and preserve the ecological environment and bio-diversity the sustainable development of favourable agricultural production.
Raising method of the present invention is realized with following technical scheme: this rearing method is characterised in that it is to utilize the flour mite of artificial culture (to comprise Lepidogtyphusdestructor, tyrophagus putrescentiae, kind of flour mite surplus the Acarus siro etc. 10), and when cultivating flour mite the offcuts of selecting grain processing for use as wheat bran as being that the artificial feed (mite) of this predation mite of amblyseius cucumeris oudeman (Amblyseius cucumeris) carry out batch production and breed in enormous quantities to cultivate and form, rice bran, various coarse food grains or cereal crops straw: comprise big, wheat straw, the rice bar, the composts or fertilisers of cultivating that the crushed material of jowar corn straw straw is bred as flour mite.The technological process of manually breeding in enormous quantities as amblyseius cucumeris oudeman comprises following (operation) step in regular turn: the flour mite artificial feed are got the raw materials ready and the processing-flour mite in early stage of feed (referring to the flour mite feed) is cultivated-and cultivate in batches as production of hybrid seeds cultivation (cultivation)-amblyseius cucumeris oudeman batch production of the amblyseius cucumeris oudeman of preying on mite and breed-examination and test of products-packed products.When the present invention implements in concrete use said method step, wherein:
One, described carry out flour mite artificial feed procedure for preparation be meant with the offcuts of grain processing or straw pulverize after 60 ℃ of-100 ℃ of high temperature oven dry sterilization in 3-6 hour is standby down.
Two, describedly carry out flour mite and cultivate operation and be meant the composts or fertilisers of cultivating such as above-mentioned wheat bran of sterilizing are packed in the culture vessel, the composts or fertilisers of cultivating water content is 5-12%, also can add an amount of yeast (also can not adding), adding flour mite (kind) back vessel port seals with paper or cloth, in case mite flight or in invade, be adjusted under the 70-95% condition 15 ℃ of-35 ℃ of temperature, relative moisture (RH) and cultivated 10-30 days, standby after the flour mite amount reaches 50-500 density of every gram in the composts or fertilisers of cultivating.
Three, the described production of hybrid seeds of carrying out amblyseius cucumeris oudeman is cultivated operation and be meant the composts or fertilisers of cultivating as the flour mite feed such as the wheat bran of sterilizing of packing into, rice bran in culture vessel, in composts or fertilisers of cultivating, throw in amblyseius cucumeris oudeman (kind) and flour mite, the ratio that both throw in is 1: 20-100, the composts or fertilisers of cultivating water content is controlled to be 5-12%, vessel port is tight with paper or fabric width, cultivated under 15 ℃ of-35 ℃ of temperature, relative moisture 70-95% (RH) condition 30-50 days, it is standby after 10-30 density range to reach in every gram composts or fertilisers of cultivating amblyseius cucumeris oudeman quantity.
Four, the described amblyseius cucumeris oudeman that carries out is cultivated in batches and is bred operation and be meant and at first carry out feeding room, the disinfection of culturing rack and culture vessel, reach and do not contain other pollution of mite classes and living contaminantses, next the composts or fertilisers of cultivating that will sterilize (as the flour mite feed with) in the culture vessel of packing into, the composts or fertilisers of cultivating water content is controlled to be 5-12%, thereafter add as the amblyseius cucumeris oudeman kind of predation mite with as the flour mite of its forage mites, both are in 1: the ratio input of 20-100, vessel port is still with cloth or paper sealing (sealing), 15 ℃ of-35 ℃ of temperature, cultivated 30-50 days under relative moisture (RH) the 70-95% condition, after amblyseius cucumeris oudeman quantity reached 20-40 density range in every gram composts or fertilisers of cultivating, can pack became the natural enemy commodity production application is provided.
