"Bio-Missile" New Technology for Pest Control
Peng Huiyin, a researcher at the Wuhan Institute of Viral Diseases, Chinese Academy of Sciences, recently demonstrated a new technology for preventing and controlling agricultural and forest pests - "biological missiles" - during the participation of academicians and experts in the "Western Going to the Countryside in Science and Technology in the Countryside". This technology is applied to mountains, hills, and water sources. The lack of pest control in the region has broad application prospects.
The "bio-missile" technology for the prevention and control of agricultural and forest pests is abbreviated as BGWM. It is based on the epidemiological theory of insect viruses and uses the egg parasitoids as vectors to spread the virus, resulting in beneficial viruses forming epidemics in host insect populations. Control the effect of the target pest. Compared with traditional prevention and control measures, this technology is safe to use, has good control effect, has a long effective period, does not harm natural natural enemies, and its control costs are 2.2 times lower than chemical pesticides, and its working efficiency is 40 times higher than conventional spraying methods. Control area can reach 100 acres.
At present, this technology has three national invention patents and is a national key promotion project issued by the State Science and Technology Commission. It is understood that China has a long history of using viruses to prevent and control agricultural and forest pests, but due to lack of understanding of its pest control laws and methods of applying chemical pesticides, the waste of beneficial viruses is quite serious (more than 90%), and the production of beneficial viruses The cost remains high. For this reason, how to reduce the cost of useful virus insecticides, simplify the application of drugs, and shorten the time of killing insects have been valued by scientists in various countries. How to spread the beneficial virus into the natural world to make the target insects get sick, domestic and foreign scholars have made some attempts, but they have not achieved the desired results. Therefore, this technology uses the egg parasitoid to deliver beneficial viruses to control the pests and solve the problems that have not been solved for many years.
