Description

Device for collecting aged larvae and pupae of drosophila melanogaster

Technical Field

The utility model relates to an insect feeding field is a device of collection black belly fruit fly mature larva and pupa.

Background

Fruit flies (including Drosophila melanogaster, Immigrans, Dermata maculata D Suzukii, etc.) are important agricultural pests for a variety of melon, fruit and vegetables. In the biological control of fruit flies, a large number of fruit flies are required to be raised as hosts for artificially breeding fruit fly parasitic wasps. The collection of the drosophila pupae is a key technical link in the artificial breeding of the parasitic wasps in the pupal stage of the drosophila. At present, the artificial culture medium is generally used for breeding a large amount of drosophila melanogaster, Drosophila haidenbergii or Drosophila melanogaster, and collecting pupae of the drosophila melanogaster and the Drosophila melanogaster. The drosophila melanogaster is a long-term model insect in genetic research, is best researched and most easily bred, and is often used as a host of drosophila parasitism. At present, by utilizing the characteristics that the black drosophila melanogaster likes dry and hard pupation places, and the like, after the aged larvae of the black drosophila melanogaster climb up to the wall of a hard plastic container from a wet culture medium, the pupae on the wall of the plastic container are washed and collected, but the mode needs to manually collect and clean the drosophila melanogaster pupae by a brush, a pair of tweezers, a water spray, a filter screen and the like, so that the time and the labor are wasted, and the method is not suitable for the requirement of mass production; moreover, the method is difficult to ensure that the pupae are consistent in day age and the pupae are very critical to parasitic wasps; furthermore, manual operations directed at pupae can damage the drosophila pupae.

In the figure: the insect collecting cabinet comprises a paper funnel, 2 square boxes, 3 insect collecting seams, 4 light gradient layers, 5 insect collecting layers, 6 cleaning layers, 7 insect collecting drawers, 8 insect collecting grooves, 9 insect collecting paper, 10 outer eaves, 11 round holes, 12 insect collecting funnels and 13 drawer cabinets.

Detailed Description

In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1~3, a device of collection black abdomen fruit fly mature larva and pupa, including vertical square box 2 of arranging paper funnel 1 in, the square box is the plastics material, the paper funnel lower extreme extends to a drawer cabinet 13 interior top, and the paper funnel is the taper, and square box lower extreme and paper funnel inner wall contact department form arcuation's collection worm seam 3, be provided with the three-layer in the drawer cabinet, top-down is light gradient layer 4 respectively and two album worm layer 5, the clearance layer 6 that all have the drawer, and light gradient layer link up from top to bottom, and the bottom has set firmly album worm groove 8 in the collection worm drawer 7 on collection worm layer, and this album worm inslot pad is equipped with album worm paper 9, collection worm seam is because square box lower extreme four corners supports in the paper funnel, the clearance that bottom four sides and paper formed.
