摘要
研究了毒绳对萧氏松茎象的防治效果，结果表明：毒绳对防治萧氏松茎象有明显的作用。各试验区的有虫株率都呈下降趋势，平均下降了41％，平均相对防治效果达52．3％。防治前有虫株率试验区和对照区没有差异，防治后试验区和对照区差异极显著。3—4月防治平均相对防治效果达68．1％，6月只有31．4％，两个不同防治时间对萧氏松茎象的防治效果差异达到了显著水平。另外，对试验样地的长期监测表明：试验区有虫株率四年下降了60％，对照区上升了13％。
The effect of the poisoned stripes was measured in slash pine.Results showed that the ratio of infested trees decreased 41.3% on average in the experimental stands. Relative control effect was achieved by 68.1% which occurred in 3-4 month, and 31.4% in 6 month. A long-time observation showed that the ratio of infested trees decreased 60% after 4 years in the experimental stands.
