Pyrethrins, a mixture of insecticidal compounds derived from the Chrysanthemum flower, demonstrate efficacy against C. fatigans mosquitoes at a concentration of 200 mg/ft^2, either alone or when combined with piperonyl butoxide on glass, wood, or mud panels, maintaining effectiveness for 3-4 weeks. This compound exhibits toxicity through oral administration and inhalation in rats (LC50s = 700 and 1,030 mg/kg for females and males, respectively; LD50= 3.4 mg/L) and to rainbow trout (LC50= 52.2 µg/L), highlighting its broad-spectrum insecticidal capabilities. Pyrethrins are utilized in agricultural and horticultural insect control formulations. Designed solely for research and analytical applications, this product is restricted to controlled laboratory environments and is not available in bulk sizes.
