Description

Climb the indoor scale cultural method of sandworm larva and pupa
Technical field
The present invention relates to cultured insect technology, more particularly to a kind of indoor scale cultivation side for climbing sandworm larva and pupa Method.
Background technology
It is Megaloptera Chi Ling sections insect to climb sandworm(Mainly huge tooth sandfly belongs to and the large-scale tooth sandfly category in part)Larva be commonly called as or It is referred to as, there is important medicinal and edible value, the good reputation for having " animal ginseng ", except having long usage history in Japan Outside, the important nourishing food of very expensive and well sold and in short supply medicine-food two-purpose is become on Sichuan, Yunnan, Guizhou and other places, not only The delicious dish for climbing sandworm can be had in big cafe, sand is also climbed in treatment children's enuresis nocturna and old man's frequent micturition etc. The contribution of worm, and have great potential of the exploitation into health products.
The stock number that nature climbs sandworm is huge, but due to environmental pollution and it is artificial the reason such as excessively capture, in recent years but drastically Decline, the sandworm that climbs in many areas is on the verge of or has become extinct.With people's diet variation and field quantity drastically reduction, Climbing sandworm is just becoming that the delicacy increasingly sold well is delicious and panacea good recipe, its commercial value and scientific research value also result in enterpriser and It is extremely urgent to climb sandworm for the concern of researcher, manually efficient cultivation.
In terms of sandworm is climbed in artificial breeding, many experts and common people did trial and explored, but substantially all with failure Come to an end, main cause is to climb the basic data of sandworm very little, and many basic Biological Knowledges are not all grasped, or even some moneys Material is wrong, and the cycle is grown in more than 1 year along with sandworm is climbed, and has four worm states, and the habit of each worm state and cultivation side Method is all completely different, so, cultivation difficulty is very big.
Since huge tooth sandfly is mainly distributed on Asia, so, it is external(Especially American-European countries)Substantially sandworm is climbed in no feeding Custom, more without research climb sandworm artificial breeding expert, even in climb sandworm culture and utilize Japan more prevailing, Only expert very a small number of Fumio Hayashi etc. carried out the cultivation that some species climb sandworm to do scientific experiment, but All without cultivating successfully, the data such as the paper of artificial culture technology are not more delivered.At home, for climbing manually supporting for sandworm Grow, the mainly Shi Zhixiong of Xichang College and Wang Fubin, Liu Yusheng of Shandong Agricultural University have delivered relevant paper.Shi Zhixiong In Xichang College's journal(Natural science edition)(2008,22(1):72-75)Paper《Seat kind water is climbed based on computer control Biology --- climb the research of sandworm artificial breeding》In propose and utilize singlechip technology, Computer Control Technology, sensor skill Art and electronic technology, the exploitation cultivation of manual simulation's natural environment climbs sandworm, but is theoretic imagination mostly, substantially to artificial breeding It is nonsensical.Shi Zhixiong is also in Xichang College's journal(Natural science edition)(2011,25(3):48-51,57)Paper《It is based on STC12C5A60S2 microcontrollers climb sandworm automatic breeding technical research》Give automatic breeding system facility method for building up With the design circuit diagram and technical parameter of control device, article also illustrates so-called " cultural technique ", but in fact very much All it is excessively general, most contents are not suitable for cultivating, more unsuitable indoor artificial breeding.In addition, this article majority content The paper delivered with Wang Fubin and Liu Yusheng《Climb the production cultural technique of sandworm》(Agricultural knowledge, 2009 (8):40-41)Repeat, This two articles give the cultural technique for climbing sandworm, but are not indoor cultures, and most technologies are general, breeding efficiency Low, many key technologies do not refer to, generally speaking, technology is immature, and practicality is not strong.
Climbing sandworm all one's life has 4 ovum, larva, pupa, adult worm states, the growth cycle of larva about one year or so, the growth of pupa About or so January in cycle, both growth cycles account for the overwhelming majority for climbing the whole growth cycle of sandworm, are the weights for climbing sandworm cultivation Point and key link or worm state, along with present and in the market in future be mainly larva and pupa various products, therefore, larva with The artificial culture technology of pupa seems extremely important.

Embodiment
A kind of indoor scale cultural method for climbing sandworm larva and pupa, includes the following steps:
(1)The construction of breeding facility
Climb the construction of sandworm culturing chamber and do not unify rigid requirement, can be but certain it is noted that following with adaptation to local conditions Key element:
1)It is as far as possible warming:Especially to winter temperature lower ground area, if culturing chamber can be warming, it can significantly improve and climb sand The survival rate and the speed of growth of worm, it is therefore desirable to built with sandwich foam plate material, can be warming, moreover it is possible to save material, apply Work also convenient quickly.
2)Result of ventilating heat dissipation is good:Especially in summer, if temperature rises sharply or ventilate bad, can be caused greatly to climbing sandworm Infringement, therefore, culturing chamber have to open big window, and pay attention to the ingehious design of window position and shape, formed good Cross-ventilation, contributes to air-dispersing of divulging information, meanwhile, also by setting multilayer sunshade net on roof top or it is set in roof portion The modes such as his heat dissipation equipment, be about to begin heat dissipation when temperature reaches more than 35 DEG C indoors, keeps indoor temperature all the time at 35 DEG C Even less than 30 DEG C.
3)Culturing chamber daylighting will be got well:Growth of the illumination to any insect is all critically important, and therefore, the structure on roof can be with Variation, but the transparent material of material, facilitate printing opacity, keep indoor lighting to work well.
4)Culturing chamber area is sufficiently large:Due to consideration that culturing chamber is also the laying coop of adult in future at the same time, it is at the same time Raising cultivation scale and benefit, can also facilitate operational administrative, so, the area of culturing chamber is the bigger the better in principle, general feelings The culturing chamber of one unit of condition is advisable at 80-120 square metres or so, simultaneously as climbing, sandworm adult build is huge, and circling in the air needs Enough height and space are wanted, so, to pay special attention to the height of culturing chamber, best wall is more than 4 meters, more than 5 meters of roof.
5)Indoor design and finishing require:In order to facilitate management and the life of suitable each worm state, side or four in culturing chamber Week will reserve the pond of 1-1.5 meters or so width, for planting the plants such as various shrubs or arbor, facilitate adult to circle in the air and stop And oviposition;Whole culturing chamber will divide some culturing areas according to the size of each frame for cultivating 7, be about 0.5 meter with width, deep The small ditch of about 0.4 meter of degree isolates each culturing area;Wall is nature dark white, is not too fancy or too bright-coloured, with Exempt to impact the adult for climbing sandworm;It is aquatic insect due to climbing sandworm, with substantial amounts of water in breeding process, so, ground Face is desirable to harden, and facilitates operational administrative.
6)Other facilities:According to indoor daylighting situation and area, in the place's suspension of more than 2.5 meters of cultivation indoor distances ground Some lighting installations, easy to night management and light filling, and are equipped with several ventilation fans, easy to assist air circulation and heat dissipation, but Will be in ventilation fan towards indoor side gauze cover, to prevent that adult from circling in the air when, which pierces, wherein escapes or is hanged; The mini-plants such as some Hygrothermographs are equipped with again, aid in scientific culture.
One frame for cultivating 7 for being used to place breeding box 4, the hard material such as iron pipe of frame for cultivating 7 are set in each culturing area Material makees stent, welds or has assembled a square frame, size is generally 1-1.5(It is wide)×4—5(It is long)×2—2.5(It is high) M, can be divided into 3-5 layers of three-dimensional culture, and every layer cultivates unit or a breeding box 4, the four walls height one of breeding box 4 for one As be 20-30cm, be separated by 50-60cm between every two layers of bottom, breeding box 4 makes of PVC or plastics or glass material With, it is desirable to waterproof and firm.Breeding box 4 is more slightly higher than other side along the side of the longitudinal axis(Specific height regard concrete condition and It is fixed), i.e. the left end of upper strata breeding box 4 tilts down, then lower floor's breeding box 4 is tilted down with regard to right end, can thus form one A gradient and be conducive to the flowing of water, the both ends of breeding box 4 are respectively arranged with water filling port and water outlet 5, and water filling port is positioned at slightly higher One end, water outlet 5 is located at lower slightly one end, and the quantity of water outlet 5 is at least 2, its diameter is about 5cm.On water outlet 5 The hose 6 with valve is connected with, the length about 10-15cm of hose 6, flows to next breeding box 4 by water guiding, realize following for water Ring utilizes.Wherein, Simple filter sieve is provided between water outlet 5 and hose 6, filter screen has the filter opening of larger aperture, Not only it can prevent that climbing sandworm enters lower floor's breeding box 4, but also easy to food with water circulation.Hose 6 is used for thorough cleaning breeding box 4 When, export the waste water for washing breeding box 4.
Frame for cultivating 7 is overall be placed on increase 50cm more each than its length and width or so, be highly 40-50cm cistern 1 in, Substantially full water is stored in pond, and the food input of sandworm will be climbed wherein.The filling pipe of the external belt switch in one end of cistern 1 10, other end bottom sets the osculum 11 of a belt switch, can thoroughly arrange sewage and swill every a period of time Go out, then replace fresh water and food.One small pump 3 is placed in cistern 1, and by water inlet pipe 2 by water pump 3 with it is most upper Layer breeding box 4 connects, and after energization, water pump 3 will pump fresh water and food in small, broken bits to the higher by one of the superiors' breeding box 4 End, water and food can be given just along longitudinal axis trickling in whole breeding box 4 and climb sandworm offer fresh water and oxygen, moreover it is possible to from Dynamic feeding, has saved largely manually, has greatly improved breeding efficiency.Current and food flow to relatively low one end of breeding box 4, will Following one layer of breeding box 4 is flowed into along water outlet 5.The corresponding one end of outlet pipe on upper strata is the higher one end of lower floor's breeding box 4, So since the gradient of breeding box 4 is conducive to the flowing of water and food, so move in circles, last water and the food not utilized It will be flowed in cistern 1 by the outlet pipe of last layer of breeding box 4, then be pumped again by water pump 3 to first layer breeding box 4, in this way, realizing the full automation circulation stereo artificial breeding of flowing water and food.4 bottom of breeding box that one layer of bottom will be away from From more than the water surface 20cm of cistern 1, it is impossible under water.In each layer of breeding box 4, sandy soil can not be put(It is so favourable In the cleaning for keeping water), but to put some latticed spacers, it is desirable to there should be some grids, be climbed with farthest isolating Sandworm, also weight and will cannot be close to 4 bottom of breeding box very much as cobblestone, just be bored to enter because climbing sandworm like that, can not Hide, but can not be too light, otherwise with regard to washed away or float, do not have the effect to climb sandworm shading and hiding.
Wherein, the top of water inlet pipe 2 bends downward and is entered by water filling port in the superiors' breeding box 4, the end after bending Portion is vertically connected with branch pipe 8, and the branch pipe 8 is parallel to the ground, and multiple through holes 9 are further opened with branch pipe 8, and the diameter 1cm of through hole 9 is left The right side, for slowing down the flow velocity of water, avoiding drenching cultivation equipment and food evenly distributes.
(2)The cultivation of larva
The cultivation of larva is segmented into two stages:One be 1-3 instar larvaes cultivation, this is very crucial one Link is, it is necessary to special and meticulous treatment and management, and especially for 1 instar larvae, the survival rate in field only has 5% or so, manually In the case of cultivation, often all dead, to after 3 ages, larva grows more healthy and strong, tides over fragile sensitive periods substantially;It Afterwards, another stage is put into, all larvas of 4 ages and afterwards age, cultivation and management method are essentially identical.Here, first Illustrate the cultural method of 1-3 instar larvaes:
Why 1 instar larvae, which is very difficult to, cultivates, and reason is mainly that the density of 1 instar larvae is very big, phenomenon of killing each other It is extremely serious, so, have to isolate in time, another reason is exactly the mouthpart very little of 1 instar larvae, can only feeding some are non- Often small protozoan is as open-mouthed bait.So for above-mentioned biological property, be in ovum when 1 instar larvae is cultivated Before hatching, the protozoans such as the wheel animalcule of sufficient amount are just cultivated in advance as bait, meanwhile, it is every being put into advance in breeding box 4 A unit sizes are about 2cm(It is long)×2cm(It is wide)×3cm(It is high)Inner wall smooth and surrounding aperture of gathering are about 1-5mm(Climb sand Worm age is bigger, and the size of groove is bigger, and cell wall aperture is bigger)Isolation channel, isolation channel for single head raise, small holes incoming Dynamic water and food, or extensive point, are directly placed into the common gauze of the serious somewhat hard of fold or the sponge of many holes of stamp Deng spacer is used as, to prevent 1 instar larvae is serious from killing each other.The hatching of ovum is paid close attention to, after egg hatching, shortest In time, 1 instar larvae is put into each isolation channel of breeding box 4 by head with the soft thing such as writing brush, or directly general 50-300 Head/square metre(Age is bigger, and density is smaller)Ground is put on the gauze for being layered on breeding box 4 or sponge.Wheel animalcule etc. is very micro- Small food is with current automatic feeding, or artificial feeding daily is once.The general ratio of feeding amount is:Every 1 instar larvae is every Its about 1-2 wheel animalcules of feeding or other similar foods, every 2 instar larvaes about feeding 2-3 wheel animalcules or similar daily Other foods, every 3 instar larvaes about 3-5 wheel animalcules of feeding or other similar foods daily.
When it grows to 4 ages and its age afterwards, larva gradually grows healthy and strong, and survival rate is gradually stablized, and food ingestion increases Greatly.The main cultivation of this period and management main points are:One is to ensure that enough optimal food, it is obtained enough battalion Support;Second, to keep the flowing of water, sufficient oxygen can be so kept, and abundant food can be brought with water, can also be in time Various discarded objects are taken away, ensure the good of water quality;It is properly isolated from, prevents third, sandworm will be climbed with certain utensil or method It is only excessive to kill each other.
The larva in this period can with feeding chironomus larvas, water earthworm, yellow meal worm, small shrimp etc., can also feeding chopping Livestock and poultry offal even man-made feeds.Can be with direct labor's feeding, can also into the water, with water automatic feeding.The bait fed Wide variety is answered, fresh and alive, no causal organism, no poisonous and harmful substance pollution.Feeding should not excessive overfrequency, food is remained according to next day Situation and the amount and number for determining feeding, or allow the food of live body to survive in water, constantly allow food to be fed with water.Food Have to it is enough, especially in the linal-instar larvae phase, due to the generation of nutrition relationship to ovum, so, climb at this time sandworm feeding and Nutrition is particularly important.Generally in dusk feeding, because larva is mostly to come out feeding at night.Swill is cleared up in time, Ensure water quality and living environment cleaning, otherwise can be easy to catch an illness.
It is typical aquatic insect to climb sandworm, and larval phase is all spent in water, therefore, cultivation of the water quality to larva to pass It is important.Clear brook water is preferred in water source, as needed to be exposed to the sun if tap water 2-3 days, it is necessary to ensure that cleaning.To keep supporting The quality for using water and oxygen content etc. are grown, the current in breeding box 4 will often be flowed according to actual conditions, general each in the morning, afternoon and evening daily Once, every time 5-10 minutes, flow velocity was about 1-1.5m/s.
It is obvious to climb the phenomenon of killing each other of sandworm, has to control cultivation density, great loss otherwise occurs.One As in the case of, if being calculated with linal-instar larvae, non-isolated groove cultivate in the case of, cultivation density control on a 50/square metre left sides The right side, certainly, age are smaller, and cultivation density can be increased suitably.Kill each other to control, except controlling cultivation density, also Suitably add some stones or water plant or other clathrate objects etc. more and be used as spacer, or simply cultivated using single head Technology cultivates.
In addition, when water temperature is too low, the measures such as heating rod can be used, water temperature is maintained at more than 20 DEG C, All the time can fast speed growth and development this ensures that climbing sandworm.
(3)The management in pupa time
Pupa time management most critical key element be exactly:Sandy soil ratio, disinfection and the humidity of sandy soil mixture needed for pupating, then just It is to prevent natural enemy from invading.
When climbing sandworm with the cultivation of above-mentioned breeding box 4, it can be used when linal-instar larvae will debark in breeding box 4 The objects such as brick do base block, put that several length differ, width is about 4 width 2/ of breeding box above the place of the water surface 3 disk 13 of pupating, surrounding about 10cm high, each side one length of snapping be pupate utensil length half plastics it is porous Butt strip 12 is taken from 13 side wall top of disk of pupating and is reached in cassette bottom water, be so conveniently intended to debark pupate climb sandworm and can climb to disk of pupating Pupate in 13 sandy soil mixture.Sandy soil mixture mainly uses thin river sand and loam, and general ratio is 1:1, it is sufficiently mixed It is placed on afterwards in 100 DEG C of drying box and is dried and sterilizes, water spray makes its humidity be 70% or so afterwards.Then sandy soil are mixed More densely covered on thing about 12 × 12cm thin tile or cobblestone or other similar to covering, easy to pupate.If More efficiently make to climb sandworm and pupate, can also be put in disk 13 of pupating by the sub-box group of size about 12 × 12 × 12cm Into isolation grid, the sandy soil mixtures of about 8cm depths is put into grid, then manually will ride up the mature larva to be pupated of bank by Bar is put into the sandy soil mixture of each grid, is finally close to grid above isolation grid again(Ensure no gap, climb sandworm It can not escape)Porous attachment strap is inserted into as covering from both sides, and the porous attachment strap of insertion is apart from sandy soil mixture about 2-4cm(Stay Go out space and pupate in order to climb sandworm activity and burrow), to pupating, the later stage can remove porous attachment strap, and native plumage is bored to facilitate Change, this ensures that the mature larva that will be pupated will not mutually fight or even massacre when burrowing, pupa will not be destroyed Room, influences to pupate, and also can adequately and reasonably utilize space, improves efficiency of pupating, simultaneously as sandy soil mixture thickness is moderate, Pupa will not beat very deep hole and pupate, convenient to find in the future and take out pupa.Further, since disk 13 of pupating is all by water segregation or remote Ground, so, the invasion of the natural enemies such as ant is not had, substantially will not be by feeding.To be kept by modes such as continuous appropriate atomized water sprays The suitable humidity of sandy soil mixture, otherwise, either it is thirst, or cause to mildew and dead due to overly wet, if finding the disease to mildew Pupa, will in time sort out and discard, in case sprawling infects.It often not renovate besides and check and pupate, otherwise can often bother, it is unfavorable In pupating.
