Evaluation of Field Dispersal and Survival Capacity of the Genetic Sexing Strain Tapachula-7 ofAnastrepha ludens(Diptera: Tephritidae)

“…However, Barry et al (2007) reported that the ability of the sterile flies to locate and feed on protein and carbohydrate sources in the field may be more important for survival than the type of food supplied before the release. Survival times in the field after release for A. ludens have been reported to be 4.7 d (Utges et al 2011) and 5.7 d (Hernández et al 2007), which are within the range reported in this study for both strains. For C. capitata, Gavriel et al (2012) reported that released adults rarely survived more than 5 d. These survival times are the minimum amount of time needed for the sterile males to reach sexual maturity, and the ability of sterile flies to survive until sexual maturity under field conditions is important for the successful use of the SIT (Thomas & LoeraGallardo 1998;Gómez-Cendra et al 2007).…”

“…For recapture of sterile flies, 64 Multilure® traps (1 trap per hectare) baited with Biolure® (ammonium acetate + putrescine) and water + propylene glycol (10%, as a preserving agent) were distributed 100 m apart in an 8 lines ´ 8 rows "grid" design with the release point at the center of the grid, as described in Hernández et al (2007) .…”

“…Recapture curves were compared by using a log rank test adjusted to an exponential regression. The life expectancy on the release day (e 0 ) for each strain was calculated by using formulas from the life table (Carey 1989;Hernández et al 2007). This method is based on the following two assumptions: 1) All ages have the same probability of being captured, and 2) flies remain in the trap area.…”

Review of Dispersal, Survival, and Establishment ofBactrocera tryoni(Diptera: Tephritidae) for Quarantine Purposes

“…After the release of 38.8 million Mediterranean fruit ßy ßiers, Meats and Smallridge (2007) found 90% of 7,863 recaptured sterile Mediterranean fruit ßy remained within Ϸ400 Ð700 m of the release point. For Rhagoletis cerasi L., 90% of ßies were trapped within 400 m of the release point (Leski 1969) and Ϸ100 Ð250 m for A. ludens and Anastrepha obliqua (Macquart) (Hernandez et al 2007). Kovaleski et al (1999) found 94.7% of Anastrepha fraterculus (Wiedemann) remained within 200 m of the release point, whereas Fletcher and Kapatos (1981) reported Bactrocera oleae (Gmelin) dispersed a mean distance of 400 m from a release point in 1 wk.…”

Efecto de las altas presiones hidrostáticas en la fisiología postcosecha del mango ‘Ataulfo’

“…Esto es importante porque se sabe que los mangos verdes de las variedades Florida presentan cambios mı´nimos externos cuando se someten a 100 MPa por 5 min (Candelario-Rodrı´guez et al, 2009). Por otra parte, la mosca de la fruta mexicana (A. ludens) y de la India occidental (A. oblicua) son las dos plagas ma´s importantes que infectan frutas en Me´xico, incluyendo los mangos destinados a exportacio´n (Camargo, Odell, & Jiro´n, 1996;Herna´ndez, Orozco, Breceda, & Domı´nguez, 2007).…”
