| 摘 要： | 为了明确蓖麻不同部位水提物和醇提物对韭菜迟眼蕈蚊的杀虫活性,采用浸虫法测定了蓖麻茎、叶、籽壳、籽粕水提物和醇提物对韭菜迟眼蕈蚊3龄幼虫的室内毒力,为采用蓖麻提取物防治韭菜迟眼蕈蚊提供理论依据。结果显示,蓖麻不同部位水提物和醇提物对韭菜迟眼蕈蚊3龄幼虫均有较高毒力,校正死亡率与提取物质量浓度和作用时间呈正相关;用质量浓度为1 g/m L的蓖麻茎、叶、籽壳、籽粕水提物和醇提物处理72 h,3龄幼虫的校正死亡率分别为59.88%、52.84%、88.51%、68.77%和56.67%、53.33%、83.33%、65.56%。提取物毒力大小顺序为籽壳水提物籽粕水提物籽壳醇提物茎水提物籽粕醇提物茎醇提物叶水提物叶醇提物。

| Abstract: | In order to clear the insecticidal activity of the water extract and alcohol extract of different parts of Ricinus communis on Bradysia odoriphaga, the toxicity of water extract and alcohol extract of stem,leaf,seed shell and caster cake of Ricinus communis against 3th instar larvae of Bradysia odoriphaga was tested with dipping-insect method in the laboratory,to provide a theoretical basis for controlling Bra-dysia odoriphaga using the extract of Ricinus communis. The result showed that both water extract and al-cohol extract of different parts of Ricinus communis had high toxicity against 3 th instar larvae of Bradysia odoriphaga. Meanwhile, the adjusted mortality rates rose with the increase of extract concentration and treatment time. The adjusted mortalities of 3th instar larvae were 59. 88%,52. 84%,88. 51%,68. 77%and 56. 67%,53. 33%,83. 33%,65. 56%,respectively after treatment of water and alcohol extracts of stem,leaf,seed shell and caster cake at 1 g/mL for 72 h. The order of toxicity was as follows: water ex-tract of seed shell＞water extract of caster cake＞alcohol extract of seed shell＞water extract of stem＞al-cohol extract of caster cake＞alcohol extract of stem＞water extract of leaf＞alcohol extract of leaf. |
