Bionomics and Management of Anastrepha
Flies of the genus Anastrepha (Diptera: Tephritidae) are among the world's most devastating agricultural pests. At the same time, they display remark­ able ecological and behavioral characteristics,Expand
Hymenopteran Parasitoids on Fruit-infesting Tephritidae (Diptera) in Latin America and the Southern United States: Diversity, Distribution, Taxonomic Status and their use in Fruit Fly Biological
The most pressing needs related to fruit fly biological control in areas of the Neotropics where fruit fly populations severely restrict the development of commercial fruit growing are discussed. Expand
Hymenopterous Larval–Pupal and Pupal Parasitoids of Anastrepha Flies (Diptera: Tephritidae) in Mexico
The surveyed wild and cultivated plant species in search of fruit fly (Diptera: Tephritidae) parasitoids during 4 years (1993‐1996) in the state of Veracruz, Mexico found 15 species infested by Anastrepha larvae, and identified 10 native and exotic larval‐pupal parasitoid species. Expand
Fruit fly (Diptera: Tephritidae) host status determination: critical conceptual, methodological, and regulatory considerations.
It is proposed that the underlying complexity determining host plant utilization by fruit flies requires a flexible systems approach capable of realistically dealing with fly/host/environment/geographic variability on a case-by-case basis. Expand
Allopatric genetic origins for sympatric host-plant shifts and race formation in Rhagoletis
Evidence is reported suggesting a surprising source of genetic variation contributing to sympatric host shifts forephritid fruit flies belonging to the Rhagoletis pomonella sibling species complex, which originated in a different time and place than the proximate ecological host shifts triggering sympatrics divergence.

Seasonal Population Fluctuations and Ecological Implications for Management of Anastrepha Fruit Flies (Diptera: Tephritidae) in Commercial Mango Orchards in Southern Mexico
A large scale and long-term study on seasonal population fluctuationsof Anastrepha fruit flies in commercial mango orchards in the Soconusco Region, Chiapas, Mexico finds significant differences in terms of total numbers of flies captured per orchard and Anastsrepha species diversity in each orchard. Expand
Functional Response and Superparasitism by Diachasmimorpha longicaudata (Hymenoptera: Braconidae), a Parasitoid of Fruit Flies (Diptera: Tephritidae)
The functional response and the effect of superparasitism of Diachasmimorpha longicaudata in larvae of Anastrepha ludens (Loew) was determined under laboratory conditions and the detrimental effects that have been attributed to superParasitism in solitary endoparasitoids are discussed. Expand
Biological control of Anastrepha spp. (Diptera: Tephritidae) in mango orchards through augmentative releases of Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae).
Populations of Ana- strepha obliqua McQuart populations were suppressed more effectively by use of parasitoids than those of Anastrepha ludens Loew, perhaps due to the type of host fruits used by each species. Expand
Morphometric analysis of Mexican and South American populations of the Anastrepha fraterculus complex (Diptera: Tephritidae) and recognition of a distinct Mexican morphotype.
Comparisons with those obtained from behavioural, karyotypic, isozyme and DNA studies suggest that sufficient evidence now exists to name a new Mexican species from within the A. fraterculus complex. Expand
