Title: Insecticide
Issue Date: Apr-2005
Publisher: CSIR
Abstract: Various biologically active molecules have been isolated from marine flora and fauna, which have applications in pharmaceuticals, nutritional supplements, cosmetics, agrochemicals, molecular probes and fine chemicals. The extracts of the marine organisms have been reported to be lethal for the larvae of marine fouling organisms including barnacles (Arthropoda). In view of this it is possible that marine organisms could provide entirely new avenues for mosquito control. Thakur and others investigated the larvicidal potential of two marine organisms like prawn and sea cucumber extracts against mosquito Culex pipens fatigans. This mosquito species is one of the important vectors of filarial nematode, Wuchereria bancrofii and reported to be highly prevalent in Mumbai region, as it breeds mainly in polluted waters. The non-polar petroleum ether extract of prawn, Nematopalaemon tenuipes and polar methanol extract of sea cucumber, Holothuria scabra body wall were found to be effective against mosquito larvae.
