12, after hatching larva, larva put in a suitable place to breed on the potted plant host plant put free choice feeding before 3 ages in a suitable place to breed.After same batch of larva got into for 3 ages, larva changed in the indoor cage and raises, and pupating to go through the phase is 20 days, and strong pupa rate can reach more than 95%, raised insect density at 600-800 bar square metre.
13, emergence generally is arranged in mid-June to mid-October naturally, gets final product with natural normal temperature.Supply and the butterfly of regulating pupa if desired view and admire live the butterfly time of letting fly away in the garden can be with the pupa low temperature storage of a dead leaf a kind of butterfly harmful to crop plants, temperature is controlled at about 12 ℃, preserves in 10 days, eclosion rate is more than 85%.
Embodiment
1, the geographical position that suits: the northern area of China refers to that this method can be implemented in northeast, northwest, North China and the area to the north of the Changjiang river of China.
2, select nature temperature-15~35 ℃, relative moisture 55~75% is below the height above sea level 700m; The sunshine time annual reaches the area without shade more than 1650 hours; Fertile soil is loose, has good bio-diversity, and the ecotope of suitable planting host plant is built a dead leaf a kind of butterfly harmful to crop plants and cultured the garden.
3, the host plant of a northern area plantation breed dead leaf a kind of butterfly harmful to crop plants is: acanthaceous indigo Strobilanthes cusia (Nees) Ktze.
4, the nectariferous plant first-selection of a northern area plantation breed dead leaf a kind of butterfly harmful to crop plants is: lantana Lantana camaraLinn; Next is: horsepower muscle JasAsclepias curassavica.
5, dead leaf a kind of butterfly harmful to crop plants culturing net garden area is advisable with 50-200 square metre.Single dead leaf a kind of butterfly harmful to crop plants culturing net garden quantity is not limit, and can a plurality ofly unite the breed garden that becomes to meet the papilio xuthus Linnaeus life habit of building.Spacing distance between net garden and net garden are mutual is at least more than 10 meters, and the good plant of plantation shaded effects makes the hedgerow band.Net garden height is 4 meters, and the top is provided with rolling type 30% sunshade net, is 30% sunshade net all around, and the phototaxis that reduces because of butterfly rests on bright place, strengthens the activity of dancing in the air of butterfly.
6, to effectively sterilizing with room, soil, article, utensil.Employ prevention is that main measure has: the inside and outside ground of 200mg/L ClO 2 solution spray booth, and every cubic metre of cultivation nutrient soil is for use after 48 hours with 0.2% formalin 100ml sprinkling and the sterilization of hybrid reactor envelope; Article, utensil are in order to following a kind of: 0.1% liquor potassic permanganate, 0.1% bromogeramine or 100mg/L ClO 2 solution spray disinfectant or washing; After reaching use before use with room especially receptacle, emergence chamber in the garden, with ultraviolet ray by every cubic metre of 1.5W sterilization.
7, the acanthaceous indigo growth adaptability is extremely wide, happiness warm moist, sun-drenched climatic environment.Suit in the place growth that water resource is abundant, soil is deep, soil property is fertile; Move into the net garden after can be potted plant in the northern area net garden; Host's class plant that need survive the winter and nectar source class plant; Should have the greenhouse, room temperature needs to impel the leafy luxuriant situation of formation branch, the collection of favourable ovum and larva according to the habit of growth setting of overwintering plant; Fruit is plucked in defloration in time, increases the output of leaf.Potted plant host plant supplies larva to search for food to carry out spray disinfectant with 100mg/L chlorine dioxide concentration solution in preceding 4 hours moving into the larva raising chamber.Host's class plant that need survive the winter and nectar source class plant should have the greenhouse, and room temperature can be according to the habit of growth setting of overwintering plant: the lantana temperature of surviving the winter is more than 8 ℃, and the lantana bud can not open when temperature was lower than 10 ℃
8, dead leaf a kind of butterfly harmful to crop plants adult has strong taxis to ethanol; So the honeybee sugar aqueous solution+5% ethanol mixing water with 10%-20% attracts the imago feeding best results; Half rotten Lee's effect is taken second place, when honeybee sugar concentration is reduced to 5% below and 30% when above, the growth of ovum is under some influence.
9, the greenhouse of laying eggs of breeding is set.Its function is at low temperature season, keeps the suitable temperature of kind of butterfly, impels kind of butterfly to continue breeding, forms generation overlap.Breeding is laid eggs greenhouse suitable mid-October to next year using mid-June, and indoor temperature is 20-30 ℃, and relative moisture is that the 55-65% breeding greenhouse of laying eggs is one of important hardware of this method.
10, every batch of ovum that collection is produced on the same day, unified carrying out disinfection is with the 25mg/L ClO 2 solution; 22 ℃ of solution temperatures soak the 2min sterilization to ovum, put into sterilization hatching ware after drying; In incubator, hatch, temperature is 28 ℃, and relative moisture is 65%.
11, larva raising chamber, emergence chamber will have anti-natural enemy measure, and 30 order screen doors, screen window are set, and isolate tank, the well-ventilated, and temperature is 20-30 ℃, relative moisture is 60-65%; Before using with use the back with disinfection by ultraviolet light 1 hour.Raise for every batch and finish to re-use after vacant three days.
12, after ovum hatches larva, in time the hatching ware is moved into the larva raising chamber, be suspended to the hatching ware on the host plant, larva can climb to free choice feeding on the host plant voluntarily.Can avoid like this causing mechanical wounding to larva.During this time, when a basin host plant when having searched for food, in time change the host plant that next basin had been sterilized, continue the confession larva and search for food to 3 ages.After same batch of larva got into for 3 ages, gather and move into raising the cage of pupa account bottom from potted plant host plant, the manual picking host plant continues to supply larva to search for food to pupating.Larva changes in the indoor cage and raises, and pupating to go through the phase is 20 days, and strong pupa rate can reach more than 95%, raises insect density at 600-800 bar square metre.Treat that taking off chrysalis after puparium hardens puts emergence chamber.Write down the label of pupating, be transferred to emergence chamber with this batch pupa.The pupa account is dismountable, and material is terylene gauze, plastics or stainless (steel) wire, is beneficial to sterilization.
13, emergence generally is arranged in mid-June to mid-October naturally, gets final product with natural normal temperature, and relative moisture is 60-90%.As the chrysalis of controlled emergence, need to move into refrigerating chamber in puparium sclerosis back, temperature is that 12 ℃, relative moisture are 60-90%, and the storing time is 10 days, when needing to sprout wings, moves in the greenhouse and sprouts wings, and temperature is 26-28 ℃, and relative moisture is 60-90%.Preserve in 10 days, eclosion rate is more than 85%.Temperature of refrigerating chamber reduces and the storage time prolongation can reduce eclosion rate greatly.
