通过使用不同浓度的番石榴抽提物处理九里香枝条上的叶片,比较柑橘木虱停留在试验组与对照组之间的数量差异,分析番石榴抽提物的驱避作用。结果表明,用高于7.5 g/L番石榴抽提物处理叶片,可观察出番石榴抽提物对柑橘木虱有驱避效果。而用15 g/L和20 g/L番石榴抽提物处理叶片,对木虱有显著的驱避作用。
The repellent effect of guava extract was analyzed by using the different concentrations of guava extracts to treat leaves on nine branches of Liriomyces, comparing the difference in the number of citrus psyllids staying between the experimental and control groups. The results showed that treatment of leaves with higher than 7.5 g / L guava extract showed that the guava extract had a repellent effect on citrus psyllid. However, the leaves were treated with 15 g / L and 20 g / L guava extract, which had a significant repellent effect on psyllids.
