Abstract: The present invention discloses an egg collecting device for black soldier flies and its oviposition plate set, comprising at least two oviposition plates which can be reused; the oviposition plates are positioned in an overlapping manner, and a gap is provided between surfaces of adjacent oviposition plates for the oviposition of black soldier flies. The egg collecting device for black soldier flies comprises a box containing oviposition-inducing material, a screen board, and the oviposition plate mentioned above; the box containing oviposition-inducing material is covered with the screen board, and the oviposition plate set is provided on the screen board. The present invention could simulate an oviposition environment according to the oviposition habits of black soldier flies, and it better induces of the oviposition of black soldier flies, providing a good foundation for large-scale, commercial oviposition of black soldier flies.

Abstract: The present invention discloses a large-scale and multi-span breeding greenhouse for adult black soldier flies, comprising greenhouse bodies. Each greenhouse body comprises a pupae room and a mating and oviposition room; a partition wall is provided between the pupae room and the mating and oviposition room, the partition wall is provided with a door hole communicating the pupae room and the mating and oviposition room; the pupae room is opaque; the greenhouse body further comprises a light guiding device which introduces sunlight into the mating and oviposition room. The present invention provides a suitable growth and breeding environment, ensures a high reproduction rate, and can achieve large-scale captive breeding of black soldier flies. The greenhouse has a high level of automation and can be easily cleaned and maintained. Little human interference takes place in the breeding process, no random oviposition is observed, and the egg collection rate is high.

Abstract: The present invention provides a fly repellent which comprises a by-product of breeding black soldier flies; the by-product comprises one or more of a pupal case of a black soldier fly, a corpse of an adult black soldier fly, and excrement of a black soldier fly. The fly repellent targets one or more types of flies including houseflies, anthomyiidae, blow flies, or flesh flies. In the present invention, a number of by-products produced during the breeding of black soldier flies are used to repel flies. The active ingredient in these by-products is fly-repelling pheromones, which could significantly decrease the lingering, foraging or ovipositioning of flies on livestock excrement, feeds or foods. The fly repellent made from the by-product of breeding black soldier flies or methods developed by using the by-product could be used in a farm environment, an animal body, a human living environment or a food processing factory.
