“…Interestingly, within a given fruit, the largest clutch sizes were registered in the albedo, the most favourable region for embryo development. The presence of eggs in the albedo was recorded for C. capitata in sweet orange, bitter orange, and lemon ), for A. ludens in grapefruit (Birke et al, 2006) and lemon (Mangan & Moreno, 2012), for Anastrepha obliqua (Macquart) in grapefruit (Mangan et al, 2011a), and for Anastrepha serpentina (Wiedemann) in grapefruit and sweet orange (Mangan et al, 2011b). The capacity of females to reach this area of the peel has been linked to the length of the ovipositor (Birke et al, 2006).…”

“…Although recent studies argue that the best approach is to work under field conditions (Aluja & Mangan, 2008), laboratory tests are useful when their aim is to determine the mechanisms involved in host resistance to pest infestation. In addition, laboratory tests are useful to explore if the resistance offered by the plant is lost by chemical and physical changes after harvest (Salvatore et al, 2004;Mangan & Moreno, 2012).…”

Citrus peel physicochemical attributes are considered the main components conferring partial or even total resistance to fruit fly (Diptera: Tephritidae) infestation. Fruit fly females adapt their ovipositional strategies to overcome such resistance. Here, we explored the effects of citrus species (Rutaceae) on the ovipositional behaviour of the South American fruit fly, Anastrepha fraterculus (Wiedemann), and on its immature development. Particularly, we investigated the effects of (1) citrus species on oviposition behaviour and immature development, (2) citrus species on oviposition preference and on the location of the eggs at different depth in the citrus peel, and (3) harvest season and post‐harvest storage time on oviposition behaviour and immature development in lemon. Citrus species influenced ovipositional behaviour and affected survival of immature stages. Females laid eggs in lemon [Citrus limon (L.) Burm.], orange [Citrus sinensis (L.) Osbeck], and grapefruit (Citrus paradisi Macfadyen). In orange and lemon, larvae were found dead close to the oviposition areas, suggesting chemically mediated resistance mechanisms. Under choice conditions, females preferred grapefruit over lemon and bigger clutches were found in the layers where embryonic development is favoured. Unsuitability of lemon as a medium to complete development was neither affected by harvest season nor by storage time of the fruit after harvest. The physical and chemical characteristics of the peel were distinctive to each citrus species and may have affected the specific levels of resistance of these citrus species to infestation by A. fraterculus.
