Deltamethrin is a synthetic pyrethroid pesticide that kills insects through dermal contact and digestion. It is applied for a range of commercial crops and recreational uses, and by extension controls a variety of pests. Synthetic pyrethroids, such as deltamethrin, are toxic substances that lead to generation of reactive oxygen species, which harm living organisms. The present study was carried out to know the effect of commercial product of deltamethrin, decis on parameter involving percentage of mortality during development in zebrafish embryos, Danio rerio. Studies shows increased mortality with increase in concentration and time. Our work illustrates that usefulness of zebrafish as a model to probe and identify the windows sensitive to toxicants, in our case decis.
