Abstract: Persistence of three pyrethroids (decis, permethrin and phenothrin) in three types of Jamaican soils - Chudleigh clay loam (CCL) Sydenham clay loam (SCI.) and Marvelly sandy loam (MSL) at three moisture levels (5, 10 and 15%) was assayed with adult Triholium conEusum. The LT50 values of LC50x4 doses of the insecticide in CCL, SCL and MSL and at 15% moisture level were respectively, 2.56, 2.25, and 3.10 for phenothrin, 3.86, 3.11 and A.09 for permethrin and 3.18, 3.98 and 3.83 for decis. The LT50 values for LC50x2 doses were generally lower than that of the higher dose being 2.49, 1.60 and 2.62 for phenothrin, 2.89, 2.56, 3.50 for permethrin and 2.06, 3.77 and 3.26 for decis, respectively.
