| 中文摘要: |
| 测定并比较3种植物对狭胸散白蚁Reticulitermesangustatus 的毒杀效果，为应用防治狭胸散白蚁提供理论基础。本文采用闹羊花 Rhododendron molle、博落回Macleaya cordata、除虫菊Pyrethrum cinerariifolium 3种常见植物为药源，选取其药用部位打成粉末，以玉米芯粉为对照，以狭胸散白蚁为靶标，测试其毒杀作用、传毒效果和趋避效果。结果表明：对狭胸散白蚁的毒杀效果以除虫菊和闹羊花为最好，当药粉质量分数达到80 %，实验第7天时闹羊花和除虫菊白蚁处理组校正死亡率达到100 %。传毒效果以除虫菊相对最好。随着染毒时间延长和中毒白蚁数量的增加，传毒效率也相应提高。3种植物均有一定的驱避效果，且以博落回的趋避作用最小。因此，这3种植物可用于防治狭胸散白蚁。 |
| 英文摘要: |
| To determine the toxic effects of three plants to termite Reticulitermes angustatus in order to provide basic data for using the herbs to its control. Take the medicinal parts of the three plants, Rhododendron molle, Macleaya cordata,Pyrethrum cinerariifolium, were ground into powder and then were used to test their toxicity toR.angustatus, the toxic transmission in the termite population, and the termite repellency to the plants.The results indicated that P.cinerariifolium andR.molle were effectively leathal to the termite workers. At the 7th day after treatment with the powder mass fraction of 80%, the corrected mortalities of the workers reached to 100% In toxicity of P.cinerariifolium was the most transmissive, and the toxic transmission efficiency increased with the time extension and the increase of poisoned termites. The termites showed certain aversion to the three plants, and repellent effects of M.cordata on the termites was relatively weak. The three plants can be used to control R.angustatus. |
