With the deepening of human understanding of nature, the research on the utilization of insects has been developing, especially the industrialization research and development and utilization of insect resources in recent years, which has greatly promoted the research on resource insects.
The industrialization of insect resources is expanding in depth and breadth at an unprecedented speed-a large number of professional insect farmers have emerged all over the country, which has promoted the development of related industries. At present, the breeding of Tenebrio molitor has formed a mature industrial chain. In this environment, locust breeding came into being and will soon become the second Tenebrio molitor.
There are many kinds of grasshoppers, about 1000 in China, which is one of the most common insects. Humans are closely related to locusts. Locust is not only a big pest in agriculture and forestry production, but also a traditional edible insect. In recent years, locusts have become a delicacy in high-end restaurants in Japan, Thailand, France and Shandong. Japanese import hundreds of tons of frozen Chinese grasshoppers from China every year. In Thailand, fried locusts with the reputation of "fried flying shrimp" have become popular health food favored by local people. As an insect food resource, locusts also have the advantages of short growth cycle and high food conversion rate, and their development prospects are quite broad.
Locust is not only a food resource for insects, but also a source of feed protein. In recent years, the comprehensive production capacity of animal husbandry has been continuously improved, the growth mode of animal husbandry has been further changed, the quality and benefit of animal husbandry have been further improved, and the continuous development of animal husbandry has been accompanied by the continuous reduction of feed, forming a certain Mao Dun. Since the beginning of this year, the feed prices in protein, which are mainly fish meal and bone meal, have soared. Although the depression of aquaculture is temporary, in the long run, the high price of conventional protein feed will still hinder the rapid development of animal husbandry. At this time, what to replace the conventional protein feed was put on the agenda, which pointed out a way for insects to provide a lot of animal protein. Tenebrio molitor as animal protein feed has been successful, and locusts as animal protein feed have also been applied to several fields, and the effect is quite good.
According to Professor Liu Yusheng, Chairman of Shandong Insect Industry Association and Shandong Agricultural University, large-scale industrialized breeding of locusts can make use of courtyards, front and back houses and idle land. It is especially suitable for large-scale centralized farming in the wild. Its breeding technology is simple and easy to learn, with the characteristics of small investment and great benefit. It is a good way to get rich in rural areas.
According to Zhao Zhanfa, a farmer in Langfang, Hebei Province, the supply of breeding locusts is in short supply, and the locusts in several greenhouses he raised have always been hot items. Lao Zhao calculated an account for us. According to the purchase of 65,438+00,000 breeding eggs, the first batch is reserved for breeding and the second batch is sold. Each batch can produce 150 kg adults, generally three batches can be produced a year, that is, 300 kg adults can be sold in the first year. According to the current market price of 20 yuan per kilogram 18 yuan, the minimum profit in the first year is 50.
