摘要
通过田间试验,研究不同密度性诱剂诱捕器对烟草虫害的诱捕效果。结果表明,随着诱捕器密度的增加,单诱捕器的诱蛾量随之减少,而单位面积的诱蛾量随之增加,且单位面积诱蛾总量的增加幅度大于单诱捕器诱蛾量的减少幅度,虫口减退率和烟株受损率均呈下降趋势,但差异不明显。建议在兼顾诱蛾效果及生产成本的情况下,田间诱捕器密度以1个/667m2为宜。
Field experiment was conducted to study the control effects of setting different density sex attractant on tobacco pests. The results showed that with the increase of trap density, the catches of single trap reduced, while the catches per unit area increased, and the total increase rate of catches per unit area was greater than the reduction rate of the catches in single trap. Insects decline rate and the damage rate of tobacco plant were both decline, but the differences were not obvious. Therefore, in the case of both control effects and production cost, trap density in field with one per 667 m2 is more suitable.
