Embodiment 1

[0047] The method that Drosophila melanogaster replaces Drosophila suzuki to breed the horned horn beetle comprises the following steps:

[0048] 1) the acquisition of Drosophila melanogaster pupae;

[0049] 1-1) Use 100-mesh nylon net to make the main body of a cubic fly cage with a side length of 55×55×55 cm. A round hole with a diameter of 15 cm is opened on the side of the main body of the fly cage, and a hole with a diameter of 15 cm is closely connected to the round hole. 50cm nylon mesh sleeve, the edge of the nylon mesh sleeve and the edge of the round hole are sewn together to form a fly cage. The connected sleeve is convenient for taking and placing the fly feed and prevents Drosophila melanogaster from escaping. It is inside the main body of the fly cage Place 4 glass petri dishes with an inner diameter of 20 cm, place 150 ml of Drosophila melanogaster medium in each petri dish, and put 1000 Drosophila melanogaster adults into the fly cage. The placed culture mediu...

Abstract

The invention provides a method for breeding trichopria drosophilae Perkins by drosophila melanogaster replacing drosophila suzukii Matsumura. The method includes the steps: firstly, winding one ringof plastics on the inner wall of an open container with drosophila melanogaster pupae; secondly, feeding the drosophila melanogaster pupae until larvae are pupated on the inner wall of the plastics; finally, inoculating the drosophila melanogaster pupae into the trichopria drosophilae Perkins, and breeding the trichopria drosophilae Perkins. Compared with the prior art, according to the method forbreeding the trichopria drosophilae Perkins by the drosophila melanogaster replacing the drosophila suzukii Matsumura, the drosophila melanogaster pupae are easily acquired as compared drosophila suzukii Matsumura phase pupae, feeding cost is low, and drosophila melanogaster pupae are more simply fed. The drosophila melanogaster replaces the drosophila suzukii Matsumura to breed the trichopria drosophilae Perkins, the progeny emergence rate of parasitic wasps is higher, the intrinsic increase rate of the parasitic wasps is higher, and the parasitic wasps are longer in life.

Description

technical field [0001] The invention belongs to the breeding technology of natural enemies of pests, and in particular relates to a method for breeding Drosophila melanogaster instead of Drosophila suzukii to breed the beetle. Background technique [0002] Drosophila suzuki (Drosophila suzuki) is a major pest of soft and thin-skinned fruits such as cherries, blueberries, blackberries, raspberries and strawberries. Most fruit flies only attack rotting fruit, such as the common species Drosophila melanogaster. But unlike most other fruit flies, D. suzukii females lay eggs in ripe fruit by cutting the fruit skin with a serrated ovipositor, and the larvae then feed on the pulp, which renders the fruit unmarketable and reduces crop yield. Drosophila suzuki causes huge economic losses worldwide. [0003] At present, the control methods of fruit flies in the blueberry orchard mainly contain the following approaches: first, chemical control methods, including the preparation of t...
