Embodiment Construction

[0038] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0039] This example discloses a method for cultivating Drosophila larvae using a liquid medium and collecting, separating, and obtaining a large number of Drosophila larvae and pupae, and provides devices required for applying the method. Specifically include: prepare liquid medium and save it for later use, use fruit fly cages to raise and grow flies; make a ventilated rearing tank for raising fruit fly larvae, add liquid medium to the breeding tank and lay gauze on the culture medium, put the breeding tank Put them into fly cages and replace them regularly to obtain fruit fly eggs; raise them until the fruit fly larvae are mature, wash them with water and filter to collect the mature larvae, and put them in a food preservation bag; after the fruit fly larvae pupate, use scissors to remo...

Abstract

The invention relates to a method and a device for propagating fruit flies by utilizing a liquid culture medium. The method comprises the following steps that (1) the liquid culture medium is prepared; (2) a fruit fly cage mode is used for feeding adult fries; (3) larvae are fed, and flyblows are obtained: (3-1) a feeding tank for feeding fruit fly larvae is manufactured; (3-2) the liquid culture medium is added into the feeding tank; (3-3) the feeding tank is put into a fly cage; (3-4) fruit flyblows are obtained; (4) after the fruit fly larvae are fed to the aging state, old and mature larvae are eluted and filtered; (5) the larvae are placed in a bag, after the fruit fly larvae are pupated, fruit fly pupae are cut off together with the bag, and undamaged fruit fly pupae are obtained. The method and the device have the advantages that various insect states, particularly older larvae and fruit fly larvae, can be easily obtained, the surfaces of the older larvae and the pupae of the obtained fruit flies are clean, and the pupa body is complete and is not damaged.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a method and a device for breeding fruit flies using a liquid medium. Background technique [0002] Drosophila belongs to the Drosophilidae insects of the Drosophila family; this kind of insects is saprophytic, widely distributed in temperate and tropical climate zones around the world, and is a common insect in life; among them Drosophila melanogaster, Drosophila Suzukii and Hyde Drosophila D.hydei etc. are important pests on fruits such as cherries and red bayberries. In orchards, fruit flies harm mature or rotten fruits. Adults lay eggs on the surface of the fruit or under the peel. After the eggs hatch, they are eaten by larvae. As the larvae eat, the fruit gradually softens, turns brown, rots and falls off. . The harm of fruit flies affects the output of related fruits; at the same time, fruit flies also affect the fresh sales of related fruits, and the existence of fr...
