景宁县茭白二化螟性诱剂应用于测报的技术探讨

Primary Study on the Forecast of Chilo Suppressalis in Zizania latifolia by Sex Pheromone in Jinning

对浙江景宁县茭白二化螟的发生情况及应用性诱剂进行测报研究,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,将明显提高茭白二化螟监测预报水平。

The status of Chilo Suppressalis in Jinning was forecasted by sex pheromone. After investigation for 1 a, the result showed that the sex pheromone has a strong ability to induce moth, the moth number induced by sex pheromone was same or slighly more than that by pest forecast lamp, and it was almost not affected by the environment. Induced measurement results could reflect the borer at 1 a occurred in the actual situation and could be applied in the actual monitoring. Sex pheromone, inducing light, the volume of stripping search field pest combination will significantly improve monitoring and forecasting Chilo Suppressalis in Zizania latifolia.
