Larvicidal Activity of the Extract of Seaweed, Caulerpa scalpelliformis, Against Culex pipiens

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… Show more

“…For instance, the acetone extract of Caulerpa scalpelliformis var. denticulata was effective against II-III instar larvae of Culex pipiens with LC 50 of 338.91 ppm (Cetin et al, 2010). Later on, Khanavi et al (2011) reported the larvicidal potential of Chondria dasyphylla and Sargassum swartzii ethanolic extracts against late III and early IV instar larvae of the malaria vector Anopheles stephensi, reporting LC 50 values ranging from 10.62 to 56.39 ppm.…”

“…Some earlier researchers have found that the acetone extracts of the marine seaweeds; Caulerpa scapelliformis, Dictyota dichotoma, Enteromorpha clathrata, E. intestinalis, and U. lactuca showed good activity against 4th instar larvae of A. aegypti with the following LC 50 values (lg/ml): 53.70, 61.65, 85.11, 67.70, and 91.20, respectively (Thangam and Kathiresan 1991). The larvicidal activity of acetone extracts of seaweed, C. scalpelliformis against 2nd and 3rd instar larvae of Culex pipiens with the following LC 50 and LC 90 values (lg/ml): 338.91 and 1891.31, respectively (Cetin et al 2010). Recent report also confirms the larvicidal efficacy of seaweed; Caulerpa scalpelliformis mediated AgNPs that showed maximum LC 50 and LC 90 values (lg/ml) of 5.86 and 12.38, respectively, for the 4th instar mosquito larvae of C. quinquefasciatus .…”

“…The larvicidal activity of the seaweed might be due to that seaweed contains effective components (i.e. alkaloids, flavonoids, terpenoids, saponins, and steroids) with larvicidal properties against mosquitoes (Cetin et al, 2010, Kalimuthu et al, 2014and Yu et al, 2014. Also, the response of mosquito larvae could depend on the type of extract and its effective concentrations.…”
