Abstract

The utility model discloses a kind of drosophila larvae and collect raising device.It is made up of glass culture dish, plastic bottle closure, cone shaped opening body, circular opening, solid culture medium, sealed membrane.Solid culture medium is prepared in the raising for drosophila larvae in glass culture dish, and cone shaped opening body vertically inserts in solid culture medium and combines closely with it, adds that the gap between sealed membrane shutoff plastic bottle closure and body just forms enclosure space.Circular opening on body is so that fruit bat breathes, in anti-locking apparatus, fruit bat escape and the outer fruit bat of device fly into, rotatable bottle cap facilitates fruit bat adult to let fly away, and device space size is suitable for the life of fruit bat adult and lays eggs, and glass culture dish bore is little to be beneficial to and to carry out in laboratory conditions observing and the selecting of different larval instar larva, device materials easily obtains, structure is simple, is easy to operation possibility strong, and the efficiency of collecting larva is high, cost is low, is suitable for using in scientific research.

Description

A kind of drosophila larvae collects raising device

Technical field

The utility model relates to biological technical field, is specifically related to a kind of drosophila larvae and collects raising device.

Background technology

Fruit bat is diptera Drosophila insect.The features such as a kind of model organism, fruit bat is because of its strong adaptability, and the history of life is short, and breeding is fast, and easily raise, mutation type is many, and individuality is little, in the historical floods of life science development, play very important role, a lot of scientific researches all be unable to do without fruit bat.

In genetic development research, often utilize fruit bat mating to breed and produce a large amount of filial generation, then fruit bat is grown, the test experience in life-span.In toxicologic study, fruit bat is often utilized to carry out the experiments such as the detection of beta galactose aldehydic acid and SABC.These take fruit bat as the experiment that object carries out, all related to the collection of drosophila larvae with select.Fruit bat adult individuality is small, and female polypide is long is often 2.5 millimeters, and male worm is than little, and fruit bat ovum and early instar larvae are more not easily observed for adult under naked eyes, and this gives in laboratory to observe to select and brings difficulty.

At present, in society, existing other types larvae collection device is applicable to the larger larva of Lepidoptera build, and it often utilizes reticulated cell, funnel, square set is collected larva, and it utilizes larva build and mesh to match, screen out the interference of other irrelevant factors, reach the object of collection.And because of the individual less reason of fruit bat, this kind of device, in collection drosophila larvae, cannot play effective help, and existing drosophila larvae gathering unit, the collection being used for extensive fruit bat adult and pupa is raised, the collection not being suitable for laboratory small-scale fruit bat adult and larva is raised, and is unfavorable for selecting of fruit bat first-instar young, and more complicated in making, not easily assemble, operation inconvenience, there is limitation in material source, cost is high.

Summary of the invention

The small-scale collection raising in laboratory is unsuitable in order to overcome existing drosophila larvae collection raising device, more complicated in making, not easily assemble, operation inconvenience, there is limitation in material source, cost is high, and is unfavorable for the shortcoming selected of fruit bat instar larvae morning, and the utility model provides a kind of drosophila larvae and collects raising device.

The utility model solves the technical scheme that its technical problem adopts: select the glass culture dish that caliber size is suitable, inwardly add solid culture medium.Select the empty plastic bottle that capacity is suitable, cutting is carried out to plastic bottle, the body of resulting tape bottle cap is vertically inserted in medium, shutoff is carried out by sealed membrane in gap after bottle cap screws on, in addition, body is also less than the hole of fruit bat build with multiple bore, the drosophila larvae that namely formation one is complete collects raising device.Wherein, because glass culture dish can be equipped with solid culture medium that fruit bat eats to be beneficial to fruit bat raising as food.Solid culture medium and the body be inserted therein are combined closely and are made body not easily slippage, reduce the use of this part sealed membrane.Plastics spout carries rotatable bottle cap, and the gap place after bottle cap screws on is by sealed membrane shutoff, therefore collection raising device defines seamless closed mode.Body, with circular opening, can be breathed for fruit bat, and small aperture is less than fruit bat and becomes polypide long, therefore can prevent adult escape and the outer fruit bat of device from piercing.Rotatable bottle cap can be convenient to let fruit bat adult fly away, and sealed membrane is readily removable to be removed and can reuse, cost-saving.Body and glass culture dish can quick separating, and swift to operate, the glass culture dish after separation carries out the observation of larva under being also easy to be placed on stereomicroscope and selects.

The beneficial effects of the utility model are, collection can be carried out to drosophila larvae easily in laboratory conditions to raise, be beneficial to selecting of fruit bat first-instar young, and make simple, be easy to assembling, disassembling section is convenient, material source is extensive, decrease body be connected with glassware needed for sealed membrane, reduce costs, practical.

Accompanying drawing explanation

Fig. 1 is structure chart of the present utility model.

In figure, 1. plastic bottle closure, 2. cone shaped opening body, 3. glass culture dish, 4. circular opening, 5. solid culture medium.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

The solid culture medium (5) of feeding required by fruit bat adult and larva is poured bore into and is greater than 7cm and is less than in the glass culture dish (3) of 10cm, after solid culture medium (5) cooled and solidified, cone shaped opening body (2) with plastic bottle closure (1) is vertically inserted in solid culture medium (5), both are combined closely, cone shaped opening body (2) pricks hole, the circular opening (4) that aperture is less than 2mm must be arrived, plastic bottle closure (1) is outwarded winding and imports fruit bat adult, then bottle cap (1) is screwed, with sealed membrane shutoff gap, fruit bat adult is laid eggs in gathering unit, after egg laying amount reaches necessary requirement, to tear plastic bottle closure (1) gap place sealed membrane, adult in device is let fly away by plastic bottle closure (1) of outwarding winding, then plastic bottle closure (1) is screwed on.

According to the length of time of required larva, can manual separation cone shaped opening body (2) and solid culture medium (5), glass culture dish (3) voluntarily, after removing cone shaped opening body (2), under glass culture dish (3) being placed in stereomicroscope mirror, selecting of larva can be carried out.

Claims
