| Abstract: | Out of 16 plant species tested for mosquito larvicidal activity, the extract of
4 plants could induce 100% mortality of larvae. The results also show that the
extract of Lantana camera 1 (pink and yellow coloured flower),
L. camera 2 (red flowered), Coriandrum
sativum and Eryngium foetidum were the most
toxic extracts against the larvae. L. camera 1 and C.
sativum showed its pronounced activity after 6 hrs. of treatment where
as E. foetidum showed its activity after 24 hrs. and
L. camera 2 after 48 hrs of treatment. Though highly aromatic
Hyptis suaveolens extract has least activity, which is only 10%
after 48hrs. The extract of Triumfetta rhoimboidea has no activity
against the larvae |
