First, the technology for the extraction and purification of jellyfish toxin was established for the first time, and the biological activity of jellyfish toxin was studied. The results of the insecticidal activity showed that the mortality rate of pear nettles reached 97.9% at 48 hours, and it had certain activity on Spirulina, peach aphid, and alfalfa; it could inhibit the growth of newly hatched larvae of Helicoverpa armigera and had more significant killing. Insect activity, and deep processing of jellyfish to develop JMT insecticides. Toxicological tests have shown that: According to China's acute toxicity classification criteria for pesticides, JMT belongs to low-toxic pesticides, and has broad prospects for development and application.
The second is that for the first time it was found that the jellyfish toxin has antioxidant activity and provides a new way for the development of new, highly effective, natural antioxidants and anti-aging drugs. The appraisal committee believes that the development of JMT, a novel marine bio-pesticide, has laid a foundation for the high-value utilization of sea bream resources and opened up new avenues for the research of new bio-sourced pesticides.
Advances in research on new marine biological pesticides in Shandong Province
Recently, Li Pengcheng, a researcher at the Institute of Oceanography, Chinese Academy of Sciences, undertook the project of “Development and Application of Novel Marine Biological Pesticide JMT†and passed expert appraisal in Shandong. The topic achieved the following innovations:
