Insect sex pheromones are widely used in the occurrence, occurrence, occurrence range, control effect of prevention and control, detection of quarantine pests, and identification of forest pest species.

(1) Forecasting of the occurrence period. It is based on the sex pheromone trap to induce the peak period of adult pests, and the period of growth and development period to predict the peak period of a certain state of the future.
(2) Measurement of the amount of occurrence. In general, the number of insects trapped by sex pheromone traps is positively related to the number of pests in the forest. Therefore, the sex pheromone priming results can be used to predict the occurrence. The number of male adults was induced by sex pheromone traps, and the future population was predicted by conversion.
(3) The measurement report of the occurrence range. In a large-scale forest area, a sex pheromone trap is uniformly disposed, and depending on whether the trap catches pests and the number of pests, the distribution area of ​​the pests and the spread range can be determined.
(4) Monitoring of control effects. After taking control measures against pests, in order to investigate the control effect, a certain number of traps can be set up in the forest land where the control measures have been taken. If a certain number of adults are still attracted, the control effect is not good. Otherwise, the explanation Good control effect.
(5) Monitoring of quarantine pests. Due to the small number of quarantine pests introduced from outside, it is difficult to monitor by general methods. For quarantine pests with sex pheromone characteristics, sex pheromone traps can be installed at quarantine sites such as ports, airports, highways, and forest areas.
(6) Identification of forest pest species. Because different insects have different sex pheromones, they can be used to identify and distinguish pest species. For example, in China, we used the crude extract of sex pheromone from the female adult of Pinus sylvestris to prove that the Japanese pine sorghum in Liaoning, Shandong, Zhejiang, Shanghai and other areas (Mr. Tang Fangde identified as Matsucoccus liaoningensis Tang) belongs to the same species.
