Effects of Deltamethrin and Endosulfan on the Population Growth of Brachionus calyciflorus at Different Algal (Scenedesmus obliquus) Densities

Abstract

Deltamethrin is a pyrethroid insecticide used extensively in China for the control of mosquitoes and invertebrate pests on a variety of crops and turf grasses. Since deltamethrin showed low toxicity to mammals and birds and limited persistence in soils, it was considered safe and has been increasingly used during the last two decades [1-2]. Endosulfan is a persistent organochlorine pesticide (OCP) used widely to protect important corps. It not only showed high persistence and slow degradation processes in environments, but also caused pesticide poisoning in many countries [3-4]. Although the Chinese government

“…Organochlorine pesticides (OCPs) are broad spectrum insecticides with high toxicity and long residual periods [1]. They have been widely used in the control of agricultural pests, antisepsis in industrial production and the treatment of human diseases, such as malaria [2]. However, they have a long half-life and bioaccumulate in the food chain [3], thus cause serious harm to human health and ecological environment [4][5][6][7].…”
