不同生草粗提物对柑橘木虱幼虫驱避作用的研究

本文以柠檬薄荷、薄荷、柠檬罗勒、藿香蓟、北京接骨草、陕西接骨草、菊苣、三叶草和黑麦草9种生草为试验材料,通过研究不同种类和不同浓度生草粗提物对柑橘木虱幼虫的驱避作用。研究结果显示,以九里香和砂糖橘嫩梢为柑橘木虱幼虫寄主植物,9种生草均对柑橘木虱幼虫均有一定的驱避作用。我们根据结果可知,薄荷、藿香蓟、柠檬薄荷对柑橘木虱幼虫的趋避效果较好。本试验研究结果将为橘园生草种植在防控柑橘木虱中的应用提供理论依据。

Study on the Repellent Effect of Crude Extracts of Different Raw Grasses on the Larvae of Diaphorina citri Kuwayama

In this paper, nine kinds of raw grasses, namely Mentha citrata, Mentha haplocalyx, Ocimum americanum L, Ageratum conyzoides L., Sambuces Williamsii Hance of Beijing, Sambuces Williamsii Hance of Shanxi, Cichorium intybus L,Trifolium repens and Lolium perenne, were used as experimental materials to study the citrus by different kinds and concentrations of crude grass extracts used as repellent effect on larvae of Diaphorina citri Kuwayama.The results showed that the primroses of citrus hibiscus larvae were the main shoots of Murraya paniculata and citrus reticulate blanco cv. shatangju, and all of the nine grasses had certain repellent effects on larvae of Diaphorina citri Kuwayama. According to the results, we can see that Mentha haplocalyx, Ageratum conyzoides L. and Mentha citrata have better avoidance effects on larvae of Diaphorina citri Kuwayama. The results of this experiment will provide a theoretical basis for the application of orange grass planting in the prevention and control of citrus hibiscus.
