Sivinski & Pereira: Wing Markings in Fruit Flies 321 DO WING MARKINGS IN FRUIT FLIES (DIPTERA: TEPHRITIDAE) HAVE SEXUAL SIGNIFICANCE?
نویسنده
چکیده
The patterned wings of tephritid fruit flies often are moved in complex manners during sexual encounters. However, there are few cases of sexual dimorphism, and wing movements also may occur in non-sexual contexts. There was no evidence that enhancing or obliterating the patterns on the wings of male Caribbean fruit flies, Anastrepha suspensa (Loew), had any effect on their sexual success. There is convergence in wing patterns with another Dipteran family, the distantly related Bombyliidae. Additional studies of mating systems with this family might illuminate the significance of similar wing patterns in tephritids.

Influence of methoprene and dietary protein on maturation and sexual performance of sterile Anastrepha ludens (Diptera:Tephritidae)
Males of polyphagous fruit flies (Diptera: Tephritidae), such as several pestiferous Anastrepha spp., emit chemical, acoustic and visual sexual signals and often aggregate in leks to attract females (Prokopy 1980; Burk 1981; Sivinski and Burk 1989). Receptive females arrive at these aggregations to choose mates, and the variance in male reproductive success is typically high, i.e. a relatively ...

The Mexican fruit fly, Anastrepha ludens Loew (Diptera: Tephritidae), is one of the most harmful pests of mango causing direct damage by oviposition on the fruit pulp. Mango for export is subjected to hydrothermal treatment as a quarantine method for the control of this pest, but exposure to heat for long periods of time reduces considerably the quality and shelf-life of treated fruit. The aim ...
