Abstract:
【Objective】 Reviewing the domestic and foreign research progress on sex pheromone identification, comprehensive prevention and control and application of Asian corn borer in recent years, in order to provide an important reference for the monitoring, early warning and green prevention and control of Asian corn borer in my country.
【Methods】 Statistical methods were used to collect literature data, and the progress of domestic and foreign literature on the research and application of sex pheromone control technology of Asian corn borer was analyzed.
【Results】 The Asian corn borer is distributed in China, South Korea, Japan, the Philippines, etc. Females release sex pheromones to attract males and then mate;The main sex pheromone components of the Asian corn borer were identified at home and abroad as cis/trans-12 tetradecanol acetate (Z/E-12-14:Ac) and n-tetradecyl acetate (14:Ac). The effects of each component were different, and there were geographical population differences in the proportion of components; At present, the sex pheromone products of the Asian corn borer have been widely used in monitoring, mass trapping and mating interference, and the integrated technology combined with other control technologies also has significant control effects; There are many factors affecting the trapping efficiency of sex pheromone lures during the application process, including sex pheromone dosage, trap type, placement height, color and environment, etc.
【Conclusion】 The Asian corn borer is distributed in the corn planting areas of many countries. There are geographical population differences in the proportion of sex pheromone of the Asian corn borer. The best component system of sex pheromone, combined with various factors affecting the trapping efficiency of sex pheromones, has achieved good results in field prevention and control of the Asian corn borer. China has assembled and integrated a set of green control technology based on sex pheromone to prevent and control the Asian corn borer.
