Black Soldier Fly Farming: Profit and Cost Analysis and Uses Introduction

AbstractBlack soldier fly farming profit and cost: the farming cost is about 5,000 yuan. Based on a farming area of 200 sq m per household, using the combined conversion treatment method of black soldier fly and microorganisms, about 20 tons of dried protein feed raw material powder and about 100 tons of microbial fertilizer can be produced, and a profit of about 100,000 yuan can be obtained. Uses of the black soldier fly: it can produce organic fertilizer and feed, can treat organic waste, can be used to treat burns, and can produce biodiesel.

I. Black Soldier Fly Farming Profit and Cost

1. The rearing method of the black soldier fly is relatively simple. Generally, greenhouses or idle houses can be used for rearing, and farming can be carried out in both the north and the south. The rearing cycle is short, the return on investment is quick, and one investment can bring returns for many years. The farming cost is about 5,000 yuan. A female lays about 800 eggs each time, and the cycle is only 7-10 days. It has relatively strong vitality and at the same time there is no risk of epidemic infection.

2. Now, as the country's requirements for manure treatment at farms continue to increase, using black soldier fly to treat manure has become a better choice for farmers. Every year, black soldier fly larvae are snapped up early by farmers and feed mills in the local area and even in other counties and cities. Based on a farming area of 200 m² per household, using the combined conversion treatment method of black soldier fly and microorganisms, about 20 tons of dried protein feed raw material powder and about 100 tons of microbial fertilizer can be produced, and a profit of about 100,000 yuan can be obtained.

II. Uses of the Black Soldier Fly 

1. It can produce organic fertilizer and feed  

Scientific research has shown that manure treated by black soldier fly can become high-quality organic fertilizer. Compared with other protein feeds, harmful bacteria such as Salmonella can hardly be detected in the body of the black soldier fly, so adding black soldier fly to feed can effectively improve feed quality. However, when the black soldier fly is used as feed, it still must undergo sterilization treatment before it can be put on the market.  

2. It can treat organic waste

(1) The black soldier fly likes to feed on poultry manure and household waste, and likes to live in relatively humid environments. Therefore, the black soldier fly can be used to treat organic waste. Moreover, research has shown that in livestock manure treated by black soldier fly, the content and types of harmful bacteria present are significantly reduced.

(2) At the same time, the content of organic matter present in the pollutants is directly proportional to the index of waste reduction by the black soldier fly. Manure treated by the black soldier fly becomes soft in texture and odorless, and can generally be used as organic fertilizer. Therefore, the black soldier fly can treat organic waste and at the same time turn it into something useful for reuse.

2. It can be used to treat burns

The black soldier fly also has wide applications in medicine. The larvae of the black soldier fly can be used to treat burns and post-wound wound healing, and also have anti-inflammatory and analgesic effects. It is a medical resource and a medicinal insect.

3. It can produce biodiesel

The body of the black soldier fly contains relatively abundant fat and is a high-quality raw material for producing biodiesel. China is a major energy-using country. If the black soldier fly is used to produce biodiesel, then the problem of China's energy shortage can be effectively solved, providing a reliable method for China's energy development.
