“…Low pressure atmosphere, in which a partial vacuum is maintained, can be insecticidal if the oxygen level is sufÞciently low for a critical period of time (Liu 2003), or if the temperature is high enough to induce dehydration (Mbata and Phillips 2004). Insect mortality during low pressure treatment is generally believed to be a result of low O 2 concentration affecting critical metabolic functions rather than any direct physical effects on the insect as suggested by Lagunas-Solar et al (2006).…”

Metabolic stress disinfection and disinfestation (MSDD) is a postharvest treatment designed to control pathogens and arthropod pests on commodities that combines short cycles of low pressure/vacuum and high CO2 with ethanol vapor. Experiments were conducted to evaluate the effect of MSDD treatment on various life stages of Ceratitis capitata (Wiedemann), Mediterranean fruit fly; Bactrocera dorsalis Hendel, oriental fruit fly; and Bactrocera cucurbitae Coquillett, melon fly, in petri dishes and in papaya, Carica papaya L., fruit. In some experiments, the ethanol vapor phase was withheld to separate the effects of the physical (low pressure/ambient pressure cycles) and chemical (ethanol vapor plus low pressure) phases of treatment. In the experiments with tephritid fruit fly larvae and adults in petri dishes, mortality was generally high when insects were exposed to ethanol and low when ethanol was withheld during MSDD treatment, suggesting that ethanol vapor is highly lethal but that fruit flies are quite tolerant of short periods of low pressure treatment alone. When papaya fruit infested with fruit fly eggs or larvae were treated by MSDD, they produced fewer pupae than untreated control fruit, but a substantial number of individuals developed nonetheless. This suggests that internally feeding insects in fruit may be partially protected from the toxic effects of the ethanol because the vapor does not easily penetrate the fruit pericarp and pulp. MSDD treatment using the atmospheric conditions tested has limited potential as a disinfestation treatment for internal-feeding quarantine pests such as fruit flies infesting perishable commodities.

La eficiencia encontrada en los tratamientos en estudio no es tan alta como la indicada en los estudios anteriormente citados, sin embargo para Liriomyza langei, con 6% de CO2, a 50 mbar y 5 °C durante 4 días, consiguió una mortandad superior al 96%.…”

ResumenEste documento describe la historia de la tecnología de atmósferas controladas, sus avances tecnológicos y sus aplicaciones, proporcionando perspectivas de investigaciones en distintos campos de estudio. Para ello se ha desarrollado una revisión de información, sobre los distintos campos donde la tecnología ha sido aplicada y su eficiencia como alternativa de tratamiento. Los estudios relacionados con este campo generados hasta la fecha, están asociados con el efecto que produce la tecnología en las características organolépticas y funcionales de determinadas frutas (aroma, calidad, potencial antioxidante, polifenoles, etc.) y en la automatización de la tecnología (adaptaciones, monitoreo computarizado), así como el efecto en el campo de la electrónica. En la mayoría de los casos la tecnología ha mostrado una mayor eficiencia que en los métodos tradicionales. Se puede concluir que debido a la amplia alternativa de aplicación y la eficiencia de la de la tecnología de atmósferas controladas, se pueden generar estudios adicionales para complementar su desarrollo futuro.

A Review AbstractThis document seeks to describe the history of the technology of controlled atmospheres, its technological advances and applications, providing research perspectives in different fields of study. For this purpose, a review of information has been developed, about the different fields where this technology has been applied and its efficiency as an alternative method. The studies related to this field generated until today are associated with the effect that the technology produces on the organoleptic and functional characteristics of certain fruits (aroma, quality, antirust potential, polyphenols) as well as the automation of the technology (adjustments, computerized monitoring), and their applications in the field of electronics. In most cases the technology has shown higher efficiency than the traditional methods. It is possible to conclude that due to the wide alternatives of applications of the technology, additional studies can be generated to complement its future development.

“…Controlled atmosphere (CA) is one of the potential alternatives that has been studied for postharvest control of insects on perishable agricultural commodities, including lettuce (Ke and Kader 1992, Whiting et al 1992, Carpenter and Potter 1994, Mitcham et al 2001, Liu 2003. CA treatments usually use elevated CO 2 .…”

The aphid Nasonovia ribisnigri (Mosley) is a common pest of lettuce in the United States. It hinders export of U.S. lettuce to the overseas market such as Japan where it is a quarantined pest. Ultralow oxygen treatments were studied for control of the insect on iceberg lettuce. Small-scale ultralow oxygen treatments in plastic jars were conducted at 1, 5, and 10 degrees C for different durations to determine effective treatment against nymphs and alates of N. ribisnigri. At oxygen levels of 0.015-0.025%, N. ribisnigri can be controlled in 3 d at 1 degrees C, 2 d at 5 degrees C, and 1 d at 10 degrees C. Large-scale ultralow oxygen treatments were conducted in bulk container treatment chambers with commercial iceberg lettuce heads for 2 d at 6 degrees C with oxygen levels of 0.015 and 0.025% and for 3 d at 3 degrees C with oxygen level of 0.015%. All treatments achieved complete control of N. ribisnigri. No negative impact on lettuce quality was detected after 2 wk of posttreatment storage. Therefore, the selected treatments have potential to be commercially developed for postharvest control of N. ribisnigri on iceberg lettuce.
