Large-scale special effects weapons against pine caterpillars, cotton bollworms, and corn borers, such as virus “bio-missilesâ€, have recently completed product testing and passed expert acceptance. The Chinese Ministry of Science and Technology, Peng Huiyin, a researcher at Wuhan Institute of Virology, and other scientific and technical personnel, have used the egg parasitoid (Trichogramma) as a medium to transmit viruses and prevent forests. New technology for crop pests. This technique makes full use of the dual characteristics of egg parasitoids and viruses, develops techniques for controlling parasitic insects by transmitting viruses to control pests, and changes traditional pest control methods. Its characteristics are that it simplifies the method of application, reduces the cost, shortens the time for killing insects, and improves the work efficiency. It can be widely used for the control of plant pests such as agriculture, forestry, fruits, vegetables, and tea. In recent years, scientists and technicians have used the "bio-missile" technology to carry out application and promotion in Hubei, Hunan, Anhui, Sichuan, Guangxi, Yunnan, Guizhou, and Liaoning provinces, accumulatively using an area of ​​100,000 mu. The experimental results show that the use of the virus "biological missile", the average pest control efficiency of 81% or more, 40 times more efficient than traditional chemical pesticides to control pests, so that the ecological environment has been protected. Experts believe that the pilot production process of the project is mature; after 19 demonstration zones, the control effect is significant, and obvious economic, ecological and social benefits are achieved; all quality indicators meet or exceed the contract requirements.
