A simple, precise and economic method was developed to evaluate the residual toxicity of a pesticide to natural enemies. The highest commercial dose recommended by the manufacturer was sprayed on Petri dishes using a Potter tower or immersing the dishes in a diluted solution of the pesticide. The relative toxicity of a pesticide was compared using mean lethal time (TL 50 's) in 4 categories. The first category comprised the most toxic responses between 0h< TL 50 < 2h, and included: Azinphosmethyl on Neoseiulus chilenensis (Dosse) and Phytoseiulus persimilis Athias-Henriot; Chlorfenvinphos on Amitus spiniferus (Br\ue8thes), Lysiphlebus testaceipes (Cresson), Pauridia peregrina Timberlake and Scutellista caerulea (Fonscolombe); Chlorpyr...
