Genetic consequences of domestication and refreshment on colonies of the South American fruit fly

Insect Science
Abstract For almost a decade, natural populations of the South American fruit fly have been targeted for control through Sterile Insect Technique projects. To ensure a sustainable supply of competitive sterile flies for this approach, it is essential to understand the effects of domestication when strains of this ...

Male seminal fluid allocation according to socio-sexual context in the South American fruit fly

Journal of Comparative Physiology A
During copulation male insects transfer sperm and seminal fluids, including accessory gland proteins (Acps) to females, produced in the accessory glands (AGs). These Acps influence female behavior and physiology, inhibiting sexual receptivity, promoting ovulation and/or oviposition.

Karyotypic and Molecular Identification of Laboratory Stocks of the South American Fruit Fly Anastrepha fraterculus (Wied) (Diptera: Tephritidae)

Journal of Economic Entomology, 2003
The taxonomic status of the tephritid pest Anastrepha fraterculus (Wied.) is a controversial subject, mainly because of misinterpretation of the observed genetic variation. In this work, the different karyotypes and DNA polymorphism of a geographically defined population from Northeastern Argentina were studied, using derived stocks maintained in the ...

Reproductive behaviour of the South American fruit fly Anastrepha fraterculus (Diptera: Tephritidae): laboratory and field studies

Physiological Entomology, 1994
Abstract. The mate choice, courtship and oviposition behaviour of laboratory‐reared and field‐collected Anastrepha fraterculus (Wied.) were compared. In laboratory cultures in Southampton the duration of male calling activity in small leks increased gradually from 1‐2h at ...

Laboratory evaluation of phytosanitary products used for control of the South American fruit fly, Anastrepha fraterculus, in organic farming

Crop Protection, 2011
Abstract The South American fruit fly, Anastrepha fraterculus (Wied.), is one of the principal pests of fruit crops in Brazil. While organic farms use several compounds to control fruit flies, such as oils, plant extracts and soaps, there is little scientific evidence of their effectiveness.

Gamma Radiation Affecting Pupation and Emergence Rates in the Medfly and the South American Fruit Fly

1993
The biological effects of gamma-radiation on eggs of different age-groups and third instar larvae of two tephritid, medfly, Ceratitis capitata (Wiedmann), and South American fruit fly, SAFF, Anastrepha fraterculus (Wiedmann), were ...
