“…Cages are kept in rooms at 24 °C and 60% RH. The temperature is adjusted to 20 °C during the winter season for better acclimation to outdoor conditions [ 22 ]. Adults develop under these conditions until they are released in the field, 48 h after achieving 50% of emerged pupae.…”

The Mediterranean fruit fly, Ceratitis capitata (Wied.), is an endemic pest in fruit-growing areas of the Spanish Mediterranean coast. In the Valencian Community, it represents a serious problem in the cultivation of citrus and numerous species of fruit, such as peach, cherry, apricot, persimmon, etc. For over 50 years, the Department of Agriculture of Valencia has led, promoted, and carried out a C. capitata control programme to protect crops, especially citrus fruits, because this community is the largest national producer and the leading region for fresh citrus exports in the world. Traditionally, pest control has been based on the use of insecticides. However, a reduction of more than 90% of a target wild population was achieved in the frame of a pilot integrated pest management (IPM) project based on the sterile insect technique (SIT), which was implemented from 2003 to 2006. Based on this successful result, in 2007 the Department of Agriculture of Valencia initiated an area-wide integrated pest management (AW-IPM) programme for the suppression of C. capitata, using the SIT as the primary control method. Complementary activities are implemented periodically in hotspots and during different time periods depending on the pest population dynamics. As a result, there has been a reduction of more than 90% in the use of insecticides by aerial means to control C. capitata, as well as a growth trend in exports of citrus and fresh fruits from the Valencian Community in recent years. This paper provides a historical review of the Valencian programme and briefly describes how technological innovations and decision-making tools have contributed to programme efficiency.

“…In the former, most matings occurred during the early part of the night (18:00 h) while in the latter, peak mating was attained only 2 h later (20:00 h), and there were significantly fewer matings. Mating behavior characteristics of massreared and sterile insects in a natural environment may be influenced by acclimatization to outdoor conditions (Pereira et al 2007). For example, Judd & Gardiner (2006) state that temperature and light transitions are common in the field as the night progresses and hence may be responsible for differences in response of mass-reared and sterile strains to these changes when released into the field.…”

“…They further state that mass-rearing could possibly affect temperature thresholds for general activity or dispersal from release locations. Pereira et al (2007) reported that intense selection pressures imposed by rearing conditions lead to shift the sequence and timing of mating away from that which is normally exhibited in the wild. The significantly early mating and large number of matings for both non-irradiated laboratory and irradiated laboratory adults in the laboratory compared with the field are indicative of adaptation to laboratory conditions, where emphasis is on high reproduction rate, earlier and shorter mating (Iwahashi 1996;Matos et al 2000).…”

“…Estos resultados son similares a los obtenidos en C. capitata, donde machos de cría mantenidos por 0, 1 y 3 días que no mostraron un incremento en su desempeño sexual (Pereira et al 2007). Sin embargo, en esta investigación se menciono la necesidad de estudiar periodos de tiempo más largos como los evaluados en este estudio.…”

“…En algunas especies, para un mejor desempeño sexual, los insectos de cría son previamente aclimatados a campo. Si bien para A. ludens (Meza y Díaz 2006) y A. obliqua (Meza et al 2002) se reporta una aclimatación de dos días antes de la prueba, existe escasa información sobre el efecto de esta medida, mientras que para Ceratitis capitata (Wiedemann) pruebas preliminares reportan que la aclimatación de machos a 0, 1 y 3 días no confiere ventaja en su comportamiento sexual (Pereira et al 2007). En esta investigación evaluamos el desempeño sexual de machos de cría estériles de A. obliqua mantenidos bajo condiciones de campo durante varios periodos de tiempo.…”

Dávila. 2011. Desempeño sexual de machos de laboratorio estériles de Anastrepha obliqua aclimatados bajo condiciones de campo. Acta Zool. Mex. (n. s.), 27(1): 17-23. RESUMEN. Se evaluó por medio de pruebas estándar de control de calidad el desempeño sexual de machos de cría estériles de Anastrepha obliqua aclimatados bajo condiciones de campo. Machos esté-riles de cría de laboratorio fueron mantenidos en un huerto de mango en jaulas de madera durante 0, 2, 4, 6 y 8 días antes de competir con machos silvestres por hembras silvestres en pruebas de desempeño sexual. Los machos de laboratorio fueron evaluados con 8 días de edad mientras los silvestres con 15 días. Este estudio fue conducido para confirmar si los insectos mantenidos lo más cerca posible a las condiciones naturales, obtienen una ventaja en su desempeño sexual con respecto a machos mantenidos en condiciones artificiales. Los resultados del estudio indicaron que la proporción de apareamientos en la prueba fue satisfactoria y los valores del índice de esterilidad relativa no muestran diferencias significativas entre los distintos tratamientos. En conclusión los datos indican que el pre-acondicionamiento de machos de A. obliqua a condiciones de campo no confiere una ventaja en el desempeño sexual con hembras silvestres en jaulas de campo, lo cual es ideal para los programas de liberación donde la técnica del insecto estéril es aplicada. Palabras clave: A. obliqua, cría masiva, aclimatación, desempeño sexual. ABSTRACT. Standard quality control tests were carried out to evaluate the sexual performance of laboratory sterile Anastrepha obliqua males acclimated under field conditions. Laboratory sterile males were maintained in a mango orchard in wooden cages for 0, 2, 4, 6 and 8 days before competing with wild males for matings with wild females in sexual performance tests. Laboratory males were evaluated at 8 days of age while wild males were 15 days old. This study was conducted to confirm whether insects kept as close as possible to natural conditions, obtain an advantage in their sexual performance Quintero
