Cultivator of house fly larvae with your own hands
Devices for rearing fly larvae and separating them from the processed substrate
Fly larvae are reared in a special rearing device. incubator, the design of which plays an important role in their development.
House Fly Maggot ( for protein in Animal Feed, Poultry Pigs and Fish, done in Zambia Commercially.
An incubator for rearing fly larvae must be easy to use, with a large output while occupying a small space.
A rearing device includes several tray cultivators, which are inserted into a single frame. The size and quantity of the trays should match the daily output of poultry droppings. A must. the height of the sides of the tray should not be lower than 17 cm. Such cultivators are convenient to use, easy to transport, compact and productive.
After cleaning the poultry houses, the fresh poultry manure from the cesspools goes into the first substrate enrichment zone. In special tanks-mixers malted sprouts or sawdust with blood, or sugarcane pulp, or simply fine sawdust of any tree species is added to the bird droppings in an amount of 10%.
After stirring all the obtained substrate is loaded into the trays-cultivators, small fly larvae that have hatched from eggs are put into the substrate, and then the trays are inserted into a rearing container.
Next zone is a zone for receiving room fly eggs. This room contains an insectarium for holding the fruiting females of the laboratory fly population. They are kept in special cages, which are equipped with light and heat sources and bactericidal irradiators. In insectarium the certain temperature and humidity parameters which parameters should be optimum for fertility of flies and their vital activity is supported.
Larval rearing containers consist of several trays-cultivators. The frame of each container is made of metal, the walls of plastic or wood. The troughs have a horizontal design and are made of galvanized sheet metal or other chemically resistant material.
A supply of fresh air is brought to the bottom of each hatchery. And in its upper part there is a suction pipe. Each exhaust duct is connected to form the main exhaust duct, at the end of which there is a biofilter. Constant extraction of accumulated thermophilic gases from the poultry manure through the chimney.
After the trays-cultivators are installed, the container is hermetically sealed and rolled to the larval rearing area, where they are connected to the ventilation duct. In this zone air temperature is constantly maintained at 30 C and fresh ventilation air at a temperature of (28 30) C is supplied to each container.
In this unit, the fly grows in horizontal troughs-cultivators, and their separation from the processed substrate is ensured by the action of high temperatures on the fly larvae. The cultivator trays have different sizes. With the same length of each tray, their width is different. All sides of the trays have closed walls along their entire length. They are mounted on the frame of the device, so that the width of the trays increases from bottom to top.
The bottom of each tray is equipped with a heat source. The thermostat on the frame is adjusted so that the heat source heats the substrate gradually and slowly in 45 minutes, and at the end of this time to create a temperature of 45°C, at which the separation of larvae from the substrate will be complete.
Such mode of operation contributes not only to a more complete separation of the fly larvae from the processed substrate, but the cost of the technological process of separating larvae and obtaining biomass will be the lowest compared with other known methods.
Studies have shown that when optimal temperature and humidity of the substrate is maintained, larval development is completed within 3.1 to 3.4 days. After this period, the container with mature, already separated from the substrate, fly larvae is rolled to the next area of the larvae removal and packing of fertilizer. Fertilizer is transported to the storehouse and the larvae to the drying area or laid to pupation, or to the refrigeration units.
Everybody can successfully cultivate fish and get sufficient income and personal benefit. Possibility to organize such garden ponds in small and big rivers, reservoirs and ponds is given by the following factors: good food resources of water reservoirs, as well as favorable hydrochemical conditions. For breeding commercial fish, you can install as many cages as the area of the pond can allow.
Such bags are attached to a floating wooden frame with a thickness of 30-40 mm. Next, the frame is fastened with the help of the shell of a metal angle (its dimensions 45x45x5 mm), already attached to her floats, which are metal drums empty volume of 100-200 liters. The number of barrels depends on the area of the frame; the bigger it is, the more barrels are necessary. The most optimal size of the frame is considered 6x4x2.5
Prepared cages for rearing fish are lowered into the water and stocked with yearlings of carp weighing no more than 25 grams. Per square meter.м. The maximum size of a fish stocking is 200 fish.
Fly larvae elimination
Few people realize that the larvae that hatch from the eggs the flies lay are very harmful to the organism. Take green meat flies, for example, which like to live in places where meat or fish are processed and sold. They lay eggs in these foods, and after 8 hours a larva emerges from them, which can live in this stage for up to 2 weeks, staying in this environment and eating spoiled food. One or two of them can not harm a man, but their large number causes parasitic diseases of entomoses group. Getting into the intestines with food, from laundry, in the ear or nose, these organisms contribute to intestinal, urogenital, nasal, ear myiasis, they affect the eyes, tissues and other organs. over, if the eggs of the insect will be deposited on the body in the area of abrasions, wounds or sores, the hatchlings can not only eat dead tissue, but also penetrate into the undamaged skin, which leads to its defects. Such as “ogres” are not found in our regions, but you can meet them on vacation in South and Central America, Africa, Brazil.
“Is it possible to kill fly larvae?”. you ask. Of course you can, today there are quite effective means to combat this infestation. Let’s look at the most popular of them.
