Abstract
Six pyrethrin esters were separated from whole pyrethrum by using high performance liquid chromatography on a silica column. Dilutions of individual esters were applied topically to house flies (Musca domestica L.) and compared to whole pyrethrum and transpermethrin. LD50's averaged from two significant dosage-mortality regressions per chemical were in ascending toxicity: Cinerin I (1.77 μjg/fly), jasmolin I (1.28 μjg/fly), pyrethrin II (0.49 μg/fly), jasmolin II (0.46 μg/fy). cinerin II (0.43 μg/fly), pyrethrin I (0.20 μg/fly)> 25% pyrethrin extract (0.11 μg/fly) and trans-permethrin (0.0072 μg/fly).
