THE ADVANCE FOR SCIENCE AND TECHNOLOGY ON FORECAST OF FOREST INSECT PESTS IN CHINA

Since 1980s,the advance of science and technology on forecast of forest insect pests in China has been made rapidly. The published reports on this area are more than 576. They can be classified sreveral fields as follows:1.The resarch on the general investigation and fauna of forest insects.2.The resarch on the technological measures of forecast of forest insect pests. The technological measures of forecast of 108 species of forest pests have been researched.3.The research on the application of advanced science and technology to forecast of forest insect pests, The computer has been successfully applied to establishing forecast databanks, expert systems, forecast systems and mangement systems; the satellite remote sence to monitoring damages of Den-drolimus punctatus; the radar to moniring adult moving trace of D. punctatus and the soft X-ray perspective photography, radiosotope marking and other technologies to forecasting forest insect pests.4. The research on the models of space distribution and the methods of sampling forest insect pests.5. The research on the methods for examining the amount of forest insect pests on high and big trees, Some methods,including counting the amount of larva's feces and yellow leaf clumps damaged by larva, vibrating trees by vibrator and so on ,to examine the amount of pests are quite effective.6. The development and application of life table of forest insect pests.7. The research on mathematical statistic forecast of forest insect pests. The study on applying widely the successive regressive analyses,grey system, topological theories and others on forecast of forest insect pests.8. The research on forecasting with trap lamps. In China, there are at least 8 orders, 83 families, 773 species of forest insect pests with phototaxis. Among them, the 558 species have middle or more phototaxis, and they may be forecast by means of trap lamps.9. The research on applying pheromone to forecast of forest insect pests. Applications of sex pheromone of Dendrolimus punctatus and other 32 species, aggregative pheromone of Ips subelonglus and trace pheromone of Coptotermes formosanus and other species to forecast for forest insect pests have been researched.10. The research on the basic theories about forecast of forest insect pests.
