--- In 2000, Animal and Plant Health Inspection Service (APHIS) notified the detection of infected fresh Peruvian asparagus shipments with eggs an larvae of Copitarsia sp., due to this, it was a phytosanitary requirement to fumigate with methyl bromide the fresh Peruvian asparagus shipments before their admission in the United States. In the present research, it is propose the use of gamma irradiation in asparagus as an alternative quarantine treatment with the purpose of assure the no emergency of adults of Copitarsia sp. in 100 %. Here, was identified was identified the species Copitarsia decolora in the Ica, Cañete and Lurin valleys; the identification was based in the genitalia extracted from adult males obtained from collected material of asparagus crops. Done the identifications, was established a breeding of C. decolora with the purpose of obtain second instar larvae to the irradiation tests. Previously to the irradiations, the Fricke dosimetry was done on larvae II of C. decolora, with the purpose of determine the absorbed dose. The Fricke dosimetry can determine low doses between 0.04 – 0.4 KGy and due to this, is chosen as a better option against chemical dosimetries. The C. decolora’s larvae II were exposed to a dose of 30Gy – 100 Gy, in this preliminary stage was determinated the minimum effective dose that assure no emergency of adults, and this was 100 Gy. Determinated the minimum effective dose a confirmatory test was done, it consisted in 10 replicas each one with 1000 larvae on second instar, obtained a mortality of 100%. The irradiation effect of C. decolora is reflected with a high mortality in the moulting process and at the same time present a lag in the biological cycle of larvae treated with irradiation. Is demonstrated that irradiation is a good alternative of quarantine treatment besides Methyl bromide.
