For the management of , botanical extracts have been used to reduce the environmental impacts of synthetic chemical pesticides. In the present investigation, the insecticidal activity of the acetonic and methanolic extracts of (Asteraceae) and of the main compound 7-hydroxy-3,4-dihydrocadalene on this pest as well as its ecotoxicological effect on were evaluated. A greater insecticidal response was obtained from the acetonic extracts than from the methanolic extracts, with LC values of 730.4 ppm and 711.7 ppm for samples 1 and 2, respectively. Similarly, there was a lethal effect on 50% of the population at low concentrations in the acetonic extract compared to the methanolic extract. The sesquiterpene 7-hydroxy-3,4-dihydrocadalene has greater insecticidal activity by presenting an LC of 44.36 ppm; however, it is classified as moderately toxic for guppy fish.
为了进行管理，植物提取物已被用于减少合成化学农药对环境的影响。在本研究中，评估了菊科植物的丙酮提取物和甲醇提取物以及主要化合物7-羟基-3,4-二氢卡达烯对该害虫的杀虫活性及其对孔雀鱼的生态毒理学效应。丙酮提取物比甲醇提取物获得了更大的杀虫反应，样品1和样品2的LC值分别为730.4 ppm和711.7 ppm。同样，与甲醇提取物相比，丙酮提取物在低浓度下对50%的孔雀鱼种群有致死作用。倍半萜7-羟基-3,4-二氢卡达烯具有更高的杀虫活性，其LC值为44.36 ppm；然而，它对孔雀鱼被归类为中等毒性。
