Description

TECHNICAL FIELD

[0001] The utility model relates to a device for removing impurities, in particular to a device for removing adult flies in the breeding of parasitic wasps using housefly pupae as hosts. BACKGROUND

[0002] As a companion pest in livestock and poultry feeding, houseflies pose a serious threat to the efficient and healthy production of livestock and poultry industry through infestation and transmission. To reduce the chemical control of fly pests in livestock and poultry industry, biological control methods have become an important means of fly pest control.

[0003] In the application of parasitic natural enemies, the use of original hosts for natural enemy production can avoid the negative effects of reduced control efficiency due to host switching. Therefore, using the pest itself as the breeding host is an effective way to ensure the effectiveness of control. As we all know, the parasitization rate in the breeding of parasitic natural enemies cannot reach 100%, so removing non-parasitized individuals is a necessary step in the production of natural enemy products. Housefly pupae, as a specific breeding material, maintaining the activity of host pupae is one of the key factors to ensure the normal development of parasitic wasps and the quality of parasitic wasps.

[0004] Although houseflies are a serious threat to livestock and human daily life safety as a worldwide health pest, they are also an important resource insect due to their high protein content in larvae, which is widely used in aquaculture and poultry breeding. Currently, fly maggot breeding technology is mature and the production cost is not high. Therefore, using housefly pupae as intermediate hosts for factory production of parasitic wasps is a good choice. As we all know, the parasitization rate in the breeding of parasitic natural enemies cannot reach 100%, so removing non-parasitized individuals is a necessary step in the production of natural enemy products. Housefly pupae, as a specific breeding material, maintaining the activity of host pupae is one of the key factors to ensure the normal development of parasitic wasps and the quality of parasitic wasps. Therefore, in the breeding of parasitic wasps using housefly pupae as intermediate hosts, non-parasitized individuals will emerge as flies. Houseflies have strong environmental pollution and disease transmission ability, and if they cannot be quickly cleaned up, not only will they pollute the surface of parasitic pupae, but also will pose a risk of potential viral contamination of parasitic wasps, and as a health pest, they will also seriously pollute the environment.

[0005] Therefore, in the breeding of parasitic wasps using housefly pupae as intermediate hosts, non-parasitized individuals will emerge as flies. Houseflies have strong environmental pollution and disease transmission ability, and if they cannot be quickly cleaned up, not only will they pollute the surface of parasitic pupae, but also will pose a risk of potential viral contamination of parasitic wasps, and as a health pest, they will also seriously pollute the environment.
