【摘要】 以闹羊花素-Ⅲ点滴亚洲玉米螟成虫,确定其亚致死剂量为0．02μg／头;用该剂量闹羊花素-Ⅲ点滴亚洲玉米螟成虫后,离体检测其触角电位(EAG)反应值。结果表明,药剂处理的亚洲玉米螟成虫与未用药剂处理的正常试虫相比,EAG值增高,EAG反应有向增高方向漂移的现象,且随叶醇浓度增高EAG反应漂移越明显。更多还原

【Abstract】 The sub-lethal dose of rhodojaponin-Ⅲagainst Asiatic corn borer adults was 0. 02 ;μg per adult. The effects of sub-lethal rhodojaponin-Ⅲon the electroantennogram (EAG) to Asiatic corn borer adults were studied in vitro. The EAG values of Asiatic corn borer adults treated topically with sub-lethal rhodojaponin-Ⅲto cis-3-hexen-l-ol were higher than that of CK’s,and the EAG values increased significantly with the increase of the cis-3-hexen-l-ol concentrations.更多还原
