Fruit flies (Drosophila melanogaster) are model research organisms and are frequently reared in research institutions. Research specimens domesticated in a laboratory-reared setting may have different behavioral phenotypes as compared to their wild counterpart. Additionally, it has been determined that the absence of “key” stimuli in the physical environment of captive animals may result in alt...

This study was designed to evaluate the effect of three concentrations of crude aqueous extracts of Hypericum triquetrifolium on (number, sex, generation and their combinations) of wild fruit flies. The concentrations (100, 50 and 25 μg/ml) were given to first generation parents in culture media and left for completing the life cycle under suitable temperature (25 Co ±2) in the modified-lighten...

BACKGROUND Chlorantraniliprole formulated as a 350 g kg(-1) WG (Altacor 35WG) for management of apple maggot Rhagoletis pomonella (Walsh), blueberry maggot R. mendax Curran and cherry fruit fly R. cingulata (Loew) (Diptera: Tephritidae) was evaluated in laboratory assays and field trials. RESULTS A tarsal contact toxicity bioassay showed that a surface residue of 500 mg L(-1) of chlorantranil...

The Mediterranean fruit fly (Ceratitis capitata) is a cosmopolitan pest of hundreds of species of commercial and wild fruits. It is considered a major economic pest of commercial fruits in the world. Adult Mediterranean fruit flies feed on all sorts of protein sources, including animal excreta, in order to develop eggs. After reaching sexual maturity and copulating, female flies lay eggs in fru...

Male fruit flies demonstrate aggression and even courtship towards other male flies. A new study reveals that these behaviors are induced via a bitter gustatory receptor.

The objective of this study is to determine the efficacy of the bait spray applications in controlling of fruit flies (Diptera: Tephritidae) on fruits and vegetables under field conditions and to make recommendations on how to move this package forward to all stakeholders. Because of concerns over damage to the environment and human health by insecticide cover sprays for fruit fly control, the ...

Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), was discovered on Tahiti Island in July 1996. Eradication programs were conducted from 1997 to 2001, but failed. From 1998 to 2006, B. dorsalis was recovered from 29 different host fruit from the five Society Islands: Tahiti, Moorea, Raiatea, Tahaa, and Huahine. Analysis of coinfestation patterns by B. dorsalis, Bactrocera...

Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system.  Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...

Tephritid fruit flies are recognized worldwide as the most important threat to horticulture (Allwood and Drew, 1997; Barnes, 2004; Ekesi and Billah, 2007). Sub-Saharan Africa (SSA) is the aboriginal home to 915 fruit fly species from 148 genera, out of which 299 species develop in either wild or cultivated fruit. They belong mainly to four genera: Bactrocera, Ceratitis, Dacus, and Trirhithrum (...
