Method: 125, 250, 500 and 1000 ppm methanol extracts of the leaves, stem and flower of L. camara were prepared and tested for their insecticidal activities against the fourth instars larva of Ae. aegypti larvae.

Results: All plant extracts showed moderate effects after 24 h of exposure; however, the LC50 of the leaves and stem methanol extracts of L. camara were 22.548 and 1695.510 ppm respectively and the flower methanol extract showed no activity. But in synergistic combination with the stem extract had the LC50 of 2175.56 ppm, while the stem and leaf methanol extract gave the LC50 of 28486.99 ppm and the flower and leaf methanol extract had the LC50 of 66419.62 ppm.

Conclusion: The plant could be used as an alternative source for mosquitocidal agents due to several plants having secondary metabolites, cost-effective, easily available and less toxic to human health.
