                          Breeding technology of black water fly

                          Select the suitable breeding place, collect the eggs for hatching, separate and feed the larvae after hatching. 1 Breeding site selection of black water fly The establishment of breeding places for black water fly should be far away from residential areas, and the place with a large amount of livestock manure and domestic waste is the best choice. For example, farms, rural vegetable markets, distilleries and other places can get a lot of cheap feed nearby, which will not cause environmental disharmony. 2 Egg collection of black water fly First of all, we should set up a trap basin outside to collect the eggs as the source of insects. Generally, the width of the gap is not more than 2 mm and the depth is not less than 7 mm. In the outdoor, choose a place with shading and rain proof, and place the lure basin. In the basin, place chicken manure, fermented bran and other odor substances. A porous egg collecting plate placed on a basin. Two days later, the cardboard with eggs was put on the feed culture box, and the hatched larvae crawled into the feed automatically. Paperboard can also be replaced by other pieces with gaps. For example, two pieces of wood are stacked together. Because the wood is naturally bent to form a gap, the black water fly can lay eggs in the gap between the boards. 3 Rearing and isolation of black water fly larvae 1. It takes 2-4 days for the eggs to hatch, and the hatching larvae crawl into the feed automatically. In the process of raising, the eggs of black water fly should be raised together with the eggs laid in one day. In this way, the larvae grow regularly and are easy to manage. At the early stage of the larva, the bran fermented for more than one day was used as the feed, and the humidity of the feed should be controlled by hand. Three to four days later, according to the density of insects in the basin, it can be fed in boxes. After this period, the larvae can choose to feed with other feeds. 2. In order to reduce the influence of odor on the environment, it is necessary to isolate the environment in the process of breeding water fly larvae. Therefore, black water fly should be cultured indoors. 4 Breeding methods of black water fly Box maintenance is a relatively simple method, suitable for indoor maintenance in small space, easy to manage. Pond culture generally adopts single layer or double layer feeding, and large area factory or simple shed is needed for production. Pond culture is extensive, and it doesn't need too much manpower input. Chicken manure and pig manure are used for breeding. The breeding cost is low, and it is suitable for promotion in rural areas. 5 Management of larva, prepupae and pupae If the black water fly is reared on a large scale, it needs a large number of eggs to ensure the continuous and large-scale production. Therefore, it is very important to cultivate the seed insects, collect and preserve the pre pupae and pupae, and to mate and collect the eggs. The basic method is to add enough and diversified feed to produce large prepupae. It can also be used in large-scale production to select prepupae with large size and strong activity ability.
