Larvicidal Activity of Silver Nanoparticles Synthesized Using Extracts of Ambrosia arborescens (Asteraceae) to Control Aedes aegypti L. (Diptera: Culicidae)

Table 2

Probit values of plant aqueous extracts and silver nanoparticles synthesized using leaves of Ambrosia arborescens against Aedes aegypti third instar larvae.

Treatment	LC50 (ppm)	95% fiducial limits (LCL–UCL)	LC90 (ppm)	95% fiducial limits (LCL–UCL)	χ^2
Plant aqueous extract	1844.61	1489.16–2146.46	6043.95	5031.51–7970.18	2.01^NS
AgNPs	0.28	0.26–0.29	0.43	0.41–0.48	0.9^NS

LC₅₀: lethal concentration that kills 50% of the exposed larvae; LC₉₀: lethal concentration that kills 90% of the exposed larvae; LCL: lower confidence limit; UCL: upper confidence limit; χ²: chi-square test; ^NSnot significant at level.
