A new view on how tissues flow in the embryo

As embryos develop, tissues flow and reorganize dramatically on timescales as brief as minutes. This reorganization includes epithelial tissues that cover outer surfaces and inner linings of organs and blood vessels. As the ...

Ignorance would be bliss: the family ties that grind

The ability to recognize relatives can make life more dangerous for the female of the species, new research carried out at the University of St Andrews, the Institute for Advanced Study in Toulouse and the University of Valencia ...

How a male fly knows when to make a move on a mate

Much like people, fruit flies must decide when the time and place are right to make a move on a mate. Male fruit flies use cues such as age and pheromones to gauge their chances of success, but just how they do that on a ...

How to tune out common odors and focus on important ones

Quantitative biologists at CSHL have figured out how a fly brain learns to ignore overwhelmingly prevalent, mundane odors to focus on more important ones. It's an important step towards understanding how our senses work and ...

Foraging Drosophila flies are open for new microbial partners

In a comprehensive ecological study, a team of scientists at the Max Planck Institute for Chemical Ecology in Jena examined three different species of the genus Drosophila and their interactions with their natural food resources, ...

A nose for trouble: Fruit flies can detect predators by smell

A study published this week in Scientific Reports by researchers from Macquarie University Applied BioSciences reveals that Queensland Fruit Fly (Q-fly) can detect the presence of potential predators by smell. Incredibly, ...

New insights into how genes control courtship and aggression

Fruit flies, like many animals, engage in a variety of courtship and fighting behaviors. Now, Salk scientists have uncovered the molecular mechanisms by which two sex-determining genes affect fruit fly behavior. The male ...

Tephritidae

Bactrocera Ceratitis Paracantha Rhagoletis Tephritis Urophora Euaresta Xyphosia hundreds more

Tephritidae is one of two fly families referred to as "fruit flies". Tephritidae does not include the biological model organisms of the genus Drosophila, which is often called the "common fruit fly". Drosophila is, instead, the type genus of the second "fruit fly" family, Drosophilidae. There are nearly 5,000 described species of tephritid fruit fly, categorized in almost 500 genera. Description, recategorization, and genetic analysis are constantly changing the taxonomy of this family. To distinguish them from the Drosophilidae, the Tephritidae are sometimes called peacock flies.

Tephritid fruit flies are of major importance in agriculture. Some have negative effects, some positive. Various species of fruit fly cause damage to fruit and other plant crops. The genus Bactrocera is of worldwide notoriety for its destructive impact on agriculture. The olive fruit fly (B. oleae), for example, feeds on only one plant: the wild or commercially cultivated olive. It has the capacity to ruin 100% of an olive crop by damaging the fruit. On the other hand, some fruit flies are used as agents of biological control, thereby reducing the populations of pest species. Several species of the fruit fly genus Urophora are questionable in their effectiveness as control agents against rangeland-destroying noxious weeds such as starthistles and knapweeds.

Most fruit flies lay their eggs in plant tissues, where the larvae find their first food upon emerging. The adults usually have a very short lifespan. Some live for less than a week.

Fruit flies use an open circulatory system as their cardiovascular system.

Their behavioral ecology is of great interest to biologists. Some fruit flies have extensive mating rituals or territorial displays. Many are brightly colored and visually showy. Some fruit flies show Batesian mimicry, bearing the colors and markings of dangerous insects such as wasps because it helps the fruit flies to avoid predators; the flies, of course, lack stingers.
