| 摘 要： | 测试了自制的12.5%马缨丹乳油对黄曲条跳甲成虫拒食活性、持效性及其与7.5%鱼藤酮乳油、1.5%除虫菊水乳剂、0.3%印楝乳油混配的联合活性。该乳油1000倍液处理菜心叶片后48h对黄曲条跳甲成虫具有40%的拒食率,随着浓度升高,拒食活性增强;200、400和600倍液处理120h后对黄曲条跳甲成虫的累计拒食率分别达到76%、68%和43%。12.5%马缨丹乳油与7.5%鱼藤酮乳油以5∶5比例混配使用时,增效作用最为明显,拒食中浓度AFC50为5.25μg.ml-1,共毒系数CTC为213;与1.5%除虫菊水乳剂以1∶9比例混配使用时的增效作用次之,共毒系数CTC为149;与0.3%印楝乳油以9∶1、7∶3、5∶5、3∶7和1∶9比例混配使用时,其共毒系数CTC均100,表现为相互拮抗作用。结果表明:12.5%马缨丹乳油对黄曲条跳甲成虫具有强烈的拒食活性,其200倍液和400倍液拒食持效性好,且该乳油可与7.5%鱼藤酮乳油混配使用。

| Abstract: | In this paper, the feeding-deterrent and persistent activities of 12.5% Lantana camara EC and its mixtures with 7.5% rotenone EC, 1.5% pyrethrum EW, or 0.3% azadirachtin EC against Phyllotreta striolata adults were tested. After treated with 1000-fold dilution of 12.5% L. camara EC for 48 h, the antifeedant rate against P. striolata was 40%, and, with increasing concentration of L. camara EC, the antifeedant rate was increased. After treated with 200-, 400-, and 600-fold dilution of 12.5% L. camara EC for 1... |
