The following insecticides were mixed with industrialized dog food: Phoxim, Chlorphoxim, Themephos (Abate), Decamethrin, Lindane, and DDT. The insecticidal effect in the blood was tested with Triatoma infestans nymphs and adults. Positive results were obtained with Phoxim and Themephos. Chlorphoxim and Lindane at efficient levels became unpalatable. Decamethrin and DDT had no lethal effect upon the insects at the levels of concentration tolerated by the dogs.
