(1): 对蚜虫的杀虫活性
蚜虫属于同翅目害虫, 具有剌吸口器, 是一种常见的农作物害虫。 以豆蚜 ( /^ craccivora) 测试对象, 米用浸渍、法测试。
操作过程:准确称量各种样品,分别加入 N,N-二甲基甲酰胺配制成 10g/L母液, 实验时用含 0.2mL/L Triton X- 100的水溶液将其稀释至 500 ug/mL的浓度。 待无翅 成蚜在豆芽上稳定吸食后, 连同豆芽一起浸入浓度为 500 ug/mL的药液中, 5s后取 出, 用吸水纸吸去多余药液, 移入干净器皿中于 23 °C恒温饲养。 每浓度设 3次重 复, 对照组为含 0.2 mL/L Triton X- 100的水溶液。 处理 24小时后, 统计试蚜的死 亡虫数, 并计算死亡率(%)。
死亡率(%)= (对照活虫数 -处理活虫数 )/对照活虫数 X 100%
(2): 对粘虫的杀虫活性
采用浸叶饲喂法。 将新鲜的玉米叶片在上述溶液中浸渍 3秒, 然后在室温下凉 干, 供试虫取食, 24h后检查并 计算试虫的死亡率(%)(公式同上), 每处理使用 10 试虫, 设 3次重复。 以清水处理作空白对照, 并计算死亡率(%)。 结果见表 1。
