Persistence of toxicity of nine different insecticidal treatments as foliar spray against the sucking pests of chillies viz., Aphis gossypii G., Scirtothrips dorsalis H., and Hemitarsonemus latus Banks was studied. The results revealed that monocrotophos 0.1% and pirimicarb 0.1% persisted upto 21 days of treatment and recorded high percentage mortality of aphids and thrips. For mites, phosalone 0.07% and monocrotophos O.1% recorded higher percentage mortality and persistance was noticed upto 21 days after treatment.
