Investigation of the Larvicidal Potential of Silver Nanoparticles against Culex quinquefasciatus: A Case of a Ubiquitous Weed as a Useful Bioresource

Table 1

Larvicidal activity of CAgNPs against different instar of C. quinquefasciatus.

Concentration (ppm)	Larva instar % mortality			LC50 (ppm) (LCL–UCL)	LC90 (ppm) (LCL–UCL)	Slope	(df = 3)
	I	II	III & IV
Control			0.00 ± 0.00
2.5			58.0 ± 16.43
5.0			76.1 ± 13.42	4.43 (3.65–5.16)	8.37 (7.84–8.90)	4.629	1.76
7.5			84.3 ± 11.40
10.0			94.5 ± 8.94

100% mortality; LC₅₀ lethal concentration that kills 50% of the exposed larvae; LC₉₀ lethal concentration that kills 90% of the exposed larvae; percent cumulative mortality values are mean ± SD.
