水稻二化螟性诱测报技术研究

Study on forecast techniques of Chilo suppressalis by using sex pheromone

多年系统调查和应用结果表明,二化螟性诱剂具有较强的诱蛾能力,其诱蛾量与测报灯的诱蛾效果相当或略高,且诱蛾量受环境影响较小。诱测结果能够反映出二化螟在1年中发生的实际情况,可在实际测报中应用。性诱、灯诱、田间虫量剥查结合,将明显提高水稻二化螟监测预报水平。

The systemic investigations in many years revealed that sex pheromone of Chilo suppressalis could strongly attract its moths. The number of moths entrapped by sex pheromone equal to, even larger than that by forecasting light trap, so the results of the sex pheromone trapping reflected actual trends of Chilo suppressalis. Surveillances by using sex pheromone, together with other surveillance methods such as forecasting light traps and field surveillances could improve accurate levels of forecasting the occurrences of Chilo suppressalis.
