Botanical products are encouraged for mosquito control because of their
low cost, rapid degradation, and low toxicity. The hexane extracts of
Cinnamomum cassia (C) and Zingiber officinale (Z) were assessed alone or
in combination on the 3rd instar of Culex pipiens. The LC50 values of C.
cassia and Z. officinale against Cx. pipiens were 317.61 and 269.4 μg mL-1,
respectively. The Z75%: C25% ratio was the most promising among the
different combinations tested, with IC50 value of 251.76 μg mL-1. The
histological sections of extract-treated larvae (C25%: Z75%) induced
degeneration of epithelial cells, degradation of microvilli, and loss of
nuclei. Antioxidant activity and phenolic content of Z. officinale hexane
extract showed a linear relationship. Z. officinale extract at 60.5 μg mL-1
possessed the highest hemolytic activity (73.9 ± 0.5%). Our results revealed
that the combined hexane extracts of C. cassia and Z. officinale provided
promising larvicidal action against Cx. pipiens.
