The estimated median lethal dose of acid lead arsenate for the Colorado potato beetle, Leptinotarsa decemlineata, larva of about 0.144 gram weight is 0.30 milligram per gram of body weight. The median lethal dose of Paris green was not closely estimated but is evidently less than one-third this amount. The consumption of food by the larva is less and the feeding time is shorter on poisoned than on normal food.
