Abstract

The larvicidal efficacy of the acetone extract of the thalli of Caulerpa scalpelliformis var. denticulata was determined against late 2nd to early 3rd instars of Culex pipiens at concentrations ranging from 100 to 2,000 parts per million (ppm). At 1,200 ppm, the extract caused >70% larval mortality at 24-, 48-, and 72-h exposure. The LC50 (lethal concentration) and LC90 values of C. scalpelliformis were 338.91 and 1,891.31 ppm, respectively. Our data showed that this species of seaweed contains components with larvicidal properties against mosquitoes.

摘要

测定了锯齿羽藻叶状体丙酮提取物对致倦库蚊二龄晚期至三龄早期幼虫的杀幼虫效力，浓度范围为百万分之100至2000（ppm）。在1200 ppm时，提取物在暴露24小时、48小时和72小时时导致幼虫死亡率>70%。锯齿羽藻的LC50（致死浓度）和LC90值分别为338.91 ppm和1891.31 ppm。我们的数据表明，这种海藻含有对蚊子具有杀幼虫特性的成分。
