蓖麻水提物和醇提物对韭菜迟眼蕈蚊的杀虫活性
Insecticidal Activity of Water Extract and Alcohol Extract of Ricinus communis on Bradysia odoriphaga
摘要
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.关键词
