| Abstract | ||
| On searching for bioinsecticides virulent to mosquito larvae; Culex pipiens, nine seaweeds species were screened. In this study, different dried seaweeds were applied into the mosquito larvae rearing jars. The effect of these seaweeds on the survival, larval development and growth rate of the mosquito Culex pipiens larvae was measured. The percentage of dead larvae fed with seaweeds species after 10 and 15 days were 50%, 90% respectively. Delayed pupation and body size reduction of the mosquitoes larvae fed with seaweeds were observed. The study showed that Caulerpa prolifera, Caulerpa serrulata, Jania rubens, Nitophyllum punctatum, Cystoseira myrica and Padina pavonica have potential to be used as larvicidal agents acting mainly to increase life cycle intervals and pupation delay. | ||
