For half a century, issues such as food safety, environmental protection, and biodiversity have prompted governments around the world to increase efforts to restrict the use of chemical pesticides. The World Conference on Environment and Development in 1992 explicitly called for the global control of the sale and use of chemical pesticides, and the use of biological pesticides should gradually reach 60% in recent years. In 1993, the US government issued a decree to reduce pesticide use. Sweden has successfully implemented a plan to reduce pesticide use by 50%, while Denmark and the Netherlands have developed "action plans" and "long-term crop protection plans" to reduce pesticide use by 50% from 1997 to 2000, respectively. China's "green food and biopesticides" have been listed as a priority development agenda for the 21st century by the government, and regulations have been formulated to restrict the use of some highly toxic pesticides and the residue levels of pesticides in food and feed. The market demand for green and pollution-free agricultural products has led to an increasing emphasis on natural enemy insects as a special resource. The research and utilization of natural enemy insects have been industrialized in developed countries such as Europe, the United States, and Japan.

Enemy insects are a type of parasitic or predatory insects that control the development and spread of pests in farmland, forest areas, and pastures. By developing large-scale production technology for natural enemy insects, adopting indoor mass breeding methods and large-scale release techniques, the initial population of natural enemies in the field can be increased. Combined with biological pesticides and ecological technologies, a relatively complete pest and disease control technology system can be formed, replacing or reducing the frequency and dosage of chemical pesticides, protecting the environment and biodiversity, and ensuring the safety of agricultural product production.

Ningbo Jiangnan Instrument Factory has developed a biological control cultivation box for natural enemy insects to address this issue, effectively solving the problem of cultivating natural enemy insects and gaining recognition from the industry.
