摘要
应用"十二齿小蠹引诱剂"开展松十二齿小蠹成虫种群数量变化的研究。结果表明:松十二齿小蠹成虫种群数量总体呈下降趋势,雌雄比稳定,种群还可能继续下降。在研究分析成虫羽化规律的基础上,提出相应的防控建议。
The population dynamics of lps sexdentatus Boerne adult were studied with attractant. The result showed the population of lps sexdentatus Boerne decreased and the sex ratio was steady in the past 4 years, which indicated the population may continue to decrease. The control methods were suggested based on the analysis of the emergence regularity of the adults.
