Treating Mexican grapefruit with gibberellic acid (GA3) before color break, significantly delayed peel color change and increased peel puncture resistance, but it did not reduce grapefruit susceptibility to Mexican fruit fly, Anastrepha ludens (Loew) attack under natural conditions. Despite GA3 treatments, larval infestation levels increased with higher fruit fly populations, which also increased as the season progressed. Late in the season, infestation levels were even higher in GA3-treated… Expand
Interplay between foraging behaviour, adult density and fruit ripeness determines the effectiveness of gibberellic acid and host-marking pheromone in reducing susceptibility of grapefruit to infestation by the Mexican fruit-fly, Anastrepha ludens
TLDR
It is found that the presence of pheromone, with or without GA3, reduced infestation to nearly zero and the findings in the context of the interplay between oviposition behaviour, fly density and fruit ripeness and the complexities involved in the design of biorational fruit-fly management schemes.

Interaction Among Peel Hardness, Fruit-Age and Gibberellic Acid on Infestation Susceptibility of Citrus Fruits by Peach Fruit Fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae)
TLDR
There is clear evidence that exogenous application of GA3 could be incorporated in IPM programmes for citrus to decrease the infestation rates by PFF, with significant differences between host types, as well as among GA3 concentrations. Expand
Effect of Resin Ducts and Sap Content on Infestation and Development of Immature Stages of Anastrepha obliqua and Anastrepha ludens (Diptera: Tephritidae) in Four Mango (Sapindales: Anacardiaceae) Cultivars
TLDR
Sap content and the number, size, and distribution of resin ducts as well as firmness in mango fruit exocarp are all involved in the resistance of mango to A. ludens and A. obliqua attack. Expand
Survival and Development of Immature Stages of the Mediterranean Fruit Fly (Diptera: Tephritidae) in Citrus Fruit
TLDR
Fruit peel was the most critical parameter for larval development and survival, drastically affecting larval survival (inducing very high mortality rates), and pulp chemical properties had rather small effects on larval and pupal survival and developmental time. Expand
Oviposition behaviour and larval development of Anastrepha fraterculus from Argentina in citrus
TLDR
Citrus peel physicochemical attributes are considered the main components conferring partial or even total resistance to fruit fly infestation and may have affected the specific levels of resistance of these citrus species to infestation by A. fraterculus. Expand
Sexual Competitiveness of Anastrepha ludens (Diptera: Tephritidae) Males Exposed to Citrus aurantium and Citrus paradisi Essential Oils
TLDR
The possibility that the positive effect of grapefruit essential oils on wildish male competitiveness may have been linked to exposure of females to grapefruit as a larval food, which may have imprinted them with grapefruit odors during pupal eclosion and biased their response as adults to odors of their maternal host. Expand
The functional significance of fruit exocarp on host selection and oviposition by Queensland fruit fly, Bactrocera tryoni (Froggatt) (Tephritidae: Diptera)
TLDR
Results showed that flies selected fruit based on their suitability for offspring survival, not because of the softness or hardness of fruit peel, which offers insights into the evolution of host use by fruit flies and their sustainable management. Expand
Application of Feces Extracts and Synthetic Analogues of the Host Marking Pheromone of Anastrepha ludens Significantly Reduces Fruit Infestation by A. obliqua in Tropical Plum and Mango Backyard Orchards
TLDR
The results confirm previous findings indicating that there is interspecific crossrecognition of the HMP in two of the most pestiferous Anastrepha species and open the door for the development of a highly selective, biorational Anastsrepha management scheme. Expand
Toxic effect of citrus peel constituents on Anastrepha fraterculus Wiedemann and Ceratitis capitata Wiedemann immature stages.
TLDR
Evidence of chemical resistance mechanisms that could account for the nonhost condition of lemon for Anastrepha fraterculus and larvae is provided. Expand
Determination of the Host Status of the ‘Persian’ Lime (Citrus latifolia Tanaka) for Anastrepha ludens (Loew) (Diptera: Tephritidae)
TLDR
Field and laboratory no-choice oviposition tests demonstrate that A. ludens, under forced infestation conditions, oviposit on limes and also on control fruit, and despite the fact that few of the immatures reached adulthood, the females obtained from limes were as fecund and fertile as those obtained from mangoes.

TLDR
It is concluded that human urine is a viable, low-tech alternative Anastrepha bait for subsistence or low income, small-scale fruit growers in rural Latin America and supports the notion that there is no “universal” AnastRepha bait. Expand

TLDR
Using fruit firmness as an indicator of fruit quality, Anastrepha ludens Loew females vary the number of eggs per clutch every time they reach an oviposition decision, and Maximising offspring survival with respect to either unripe or ripe fruit requires placing large clutch in firm fruit and smaller clutches in soft fruit.
