The following work arises from the need to experiment and observe the residual effect of chemical applications of insecticides such as Spinosad, Imidaclorip, Dimethoate, Chlorpyrifos, Methamidophos, Cypermethrin and Methomyl and also of products that act by suffocation on the beneficial fauna that develops in crops, such as asparagus. It was carried out in the Irrigation Research Unit of the Department of Soils and the Toxicology laboratory of the Entomology area of the Universidad Nacional Agraria La Molina. The observations were made in march 2000, having made the foliar applications of the treatments to asparagus from March 14 to 30, the leaves or infested foliage were collected and deposited in petri dishes. The results show that there are significant differences in three of the nine treatments (3 insecticides cause death in insects due to their residual effect). However, these statistical differences disappear after 48 hours, from which all insecticides behave homogeneously without causing mortality in insects. Insecticides that behave causing lethal damage to Chrysoperla larvae due to their residual effect after being in contact 24 hours with the foliage applied with them, are Methomyl, Methamidophos and Chlorpyrifos. Insecticides that do not cause the lethal effect on larvae are Spinosad, Imidacloprid, Dimethoate, Cypermethrin and Sulfur.
