Abstract
The present invention provides a kind of flaking method of microexamination Aphytis, is handled by Tissue lysates, alcohol, caryophyllus oil etc., after dissection, after the fixed drying of canada balsam, completes film-making.The method of the present invention can either guarantee that Aphytis sample can be obviously observed the prominent microstructure of median segment rear fan-shaped, and carry out identification of taking pictures, and can guarantee the slide sample persistence of production.
Description
Technical field
The invention belongs to aphid chalcid fly (parasitic wasp) microexamination technical fields, and in particular to microexamination Aphytis is (outstanding
It is that median segment rear fan-shaped is prominent) flaking method.
Background technique
Aphytis (Aphytis) it is subordinate to Hymenoptera (Hymenoptera) aphid Chalcididae (Aphelinidae), it is shell
The important parasitic wasp of worm, plays a significant role in biological control of insect pests.But Aphytis individual is small, needs to make slide
Sample carries out microexamination and taxonomic identification.The prominent shape of Aphytis median segment rear fan-shaped, arrangement are category classification mirror
Fixed most important feature, this feature need the microexamination of high quality that could obtain.And at present in relation to Aphytis slide mark
This main two kinds of production method:
1. conventional neutral gum mounting method: first sample being placed in 5% potassium hydroxide (or 5% sodium hydroxide) solution and is impregnated, so
After wash 20-30min, by the various concentrations dehydration of alcohol such as 50%, 70%, 95%, 100%, move into caryophyllus oil in case film-making.Film-making
When the sample in caryophyllus oil is chosen on coverslip (be inverted, i.e. the outside of belly upward), and drip a little caryophyllus oil, inhaled after dissection, whole appearance
Dry caryophyllus oil adds neutral gum mounting.The deficiency of conventional neutral gum mounting method: the sample of neutral gum mounting can be permanent
It saves, but unfortunately sample is easily deformed or shrinkage during dehydration, clarity and transparency are not ideal enough, almost very
Difficulty sees the prominent microstructure of Aphytis median segment rear fan-shaped clearly.
2. He Shi liquid method of tableting: sample first passes through the immersion liquid of acetic acid lactic acid phenol, and (lactic acid: it is molten that lactic acid phenol is made in crystalline phenol=10:5
Liquid, then lactic acid phenol solution: glacial acetic acid=5:7 is mixed) processing 6-24h, moved on to when polypide is transparent dissection on coverslip,
Whole appearance, then with He Shi liquid, (12g gum arabic, 20ml water-solubleization, add 20-40g chloraldurate and 10-20g glycerol is mixed
Close) mounting.The deficiency of He Shi liquid method of tableting: although slide sample clarity is preferable, the slide sample being fabricated to due to
He Shi liquid category water-soluble glue, easily moisture absorption are got damp, and the sample of institute's mounting cannot make persistence.
Summary of the invention
The purpose of the present invention is to provide a kind of flaking methods of microexamination Aphytis, solve and deposit in the prior art
It is easily deformed or shrinkage in product sample, clarity and transparency are not ideal enough, are difficult to see Aphytis median segment rear clearly
The disadvantages of prominent microstructure of fan-shaped, easily moisture absorption are got damp, and the sample of institute's mounting cannot make persistence.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of flaking method of microexamination Aphytis, described method includes following steps:
(1) 100% alcohol impregnates, cleans fresh Aphytis sample；
(2) Aphytis sample is put into 1.5ml centrifuge tube, 90ul Tissue lysates and 10ul Proteinase K is added, is put into 56
DEG C water-bath in, overnight；
(3) solution after staying overnight is sopped up, retains Aphytis sample, it is rear that 200ul100% alcohol is added；
(4) a spill glass slide is taken, Aphytis sample is drawn onto glass slide recess together with alcohol, it is clean simultaneously to alcohol volatilization
10ul pure water is added, sample back is upward；
(5) when the volatilization of Aphytis sample back skin pure water is clean, sample is placed in microscopic photography under microscope and is fanned
Shape lug structure；
(6) after shooting, extra pure water is sopped up, drop 20ul caryophyllus oil floods Aphytis sample；
(7) a common glass slide is taken, Aphytis sample is moved on on common glass slide together together with caryophyllus oil, is dissected, carefully
Head, feeler and wing are removed, the whole appearance of polypide is left；
(8) extra caryophyllus oil is sopped up with filter paper, adds a thin layer canada balsam, fix head, feeler, wing and polypide；
(9) it is dried 24 hours using 40 DEG C of baking piece machines；
(10) sample of above-mentioned drying is taken, is successively added canada balsam 2-3 times, head, feeler, wing and polypide difference are finally made
It is buried in canada balsam；
(11) before canada balsam does not solidify completely, round coverslip mounting is taken；
(12) it is dried 2 weeks using 40 DEG C of piece machine of baking until drying, to effectively remove the bubble in glue；
(13) sample after drying is placed in microscopically observation, shooting.
The Tissue lysates are 10 mM Tris-HCl, 100mM EDTA, 1wt.% SDS, pH 8.0.
The present invention has the advantages that
The application motion can either guarantee that Aphytis sample can be obviously observed prominent microcosmic of median segment rear fan-shaped
Structure, and identification of taking pictures is carried out, and can guarantee the slide sample persistence of production.

Specific embodiment
Embodiment 1
1. 100% alcohol impregnates, cleans fresh Aphytis sample；
2. Aphytis sample is put into 1.5ml centrifuge tube, addition 90ul Tissue lysates (10 mM Tris-HCl,
100mM EDTA, 1% SDS, pH 8.0) and 10 ul Proteinase Ks, it is put into 56 DEG C of water-bath, overnight；
3. the solution after overnight is sopped up, retain Aphytis sample, it is rear that 200ul100% alcohol is added；
4. taking a spill glass slide, Aphytis sample is drawn onto glass slide recess together with a small amount of alcohol, simultaneously to alcohol volatilization
10ul pure water is added, sample back is upward；
5. sample is placed in Nikon microscope (Eclipse when the volatilization of Aphytis sample back skin pure water is clean
Ni-U microscopic photography fan-shaped lug structure under)；

7. taking a common glass slide, Aphytis sample is moved on on common glass slide together together with caryophyllus oil, is dissected, carefully
Remove head, feeler and wing, the remaining whole appearance of polypide；
8. sopping up extra caryophyllus oil with filter paper, add a thin layer canada balsam, fixes head, feeler, wing and polypide；
9. being dried 24 hours using drying (40 DEG C) of piece machine；
10. taking the sample of above-mentioned drying, successively add canada balsam 2-3 times, finally makes head, feeler, wing and polypide difference
It is buried in canada balsam.Since wing and feeler thickness are small, a small amount of canada balsam of addition, 2 times；Head and
Polypide thickness is larger, to be successively added canada balsam 3 times, is buried in it completely clear when observing in natural gum to improve
Degree.
11. taking round coverslip (diameter 0.6cm) mounting before canada balsam is not completely dried；
