On 6 June, Prof. Li Shiyou from Stefen F. Austin State University, Texas, U.S., was invited to visit Research Institute of Tropical Forestry for academic exchanges. He made a presentation titled Endocide theories and application.

Prof. Li Shiyou stated that research should aim at new content and practicability, and translate new theories into new science. This should be the philosophical idea. He listed a large number of research and application examples including plant bioactive substances and their products’ research and application, cultivation of new species and control of invasive species. He proposed the endocide theories, which can be used to induce mutation and control the growth, development and reproduction of parents of fauna and flora in a selective manner. He also elaborated on the role of endocide (which is a biochemical-like compound, and a natural substance which controls specific bio-parents through toxic mechanisms), and analyzed its application advantages and market potential. After the presentation, Prof. Li discussed with the researchers on cooperation in endocide or plant chemistry in forest resources cultivation.

Prof. Li Shiyou is the Director of National Center for Pharmaceutical Crops of the U.S. Since 1993, he has conducted research on bioactive substances in fauna and flora in the U.S., involving R&D of anti-cancer plant drugs and invasive species. His research results were reported on TV. In the past 30 years, Prof. Li and his team have aimed at R&D of new anti-cancer drugs, and have separated more than 2000 natural products, including 186 new compounds, endemic or alien in southeastern U.S. They discovered metabolic adjustment functions of endocide in plant parents and proposed the endocide or endogenous biocide theories, which provide a new method to induce mutation and control the growth, development and reproduction of parents of fauna and flora in a selective manner. The application of endocide led to R&D of 6 high-yield pharmaceutical crops and several ideal arbor and herbal dwarf species. The endocide technologies also revealed large market potential, which can be used to control over 120 invasive fauna and flora species in laboratories, greenhouses and field experiments. Prof. Li published 4 books and 71 articles. He has 15 patents, and discovered more than 20 new varieties, mutations or/and species of plants. (Zhong Chonglu, Research Institute of Tropical Forestry)
