Fly of cherry

See also: Fly

The fly of the cherry is small a Insecte about the Diptère S, whose Larve develops in the Cerise S.

Scientific name: Rhagoletis cerasi Loew, family of the Tephritidés.

Description

The adult insect is a small fly of less than 5 mm length, with the decorated transparent wings of dark spots. By far one can take the fly for a jumping Araignée (spots representing the legs).

The Larve is a worm of white color, 5 mm length, which lives in the flesh of cherries.

Damage

At the time of the tasting of Cherry S blackberries, one can fall on small a Asticot blanchâtre hidden in the middle of the fruit, very close to the core. It happens that the pulp of the fruit rotted then browns. The attacked fruits are noticed with the presence of a tiny opening located to the top of the fruit close to the stalk, by which the larva left cherry.

This insect attacks only the Cerisier.

Biological cycle

The biological cycle of the fly of cherry is spread out over one year complete:

  • the larva of the fly Rhagoletis cerasi is born in the fruits in the course of reddening at spring (from May to June/July in the northern hemisphere) then continues its development on the ground while being transformed into Pupe and hibernates under ground.

  • the adults hatch at the beginning of spring and the Femelle S lay their eggs in the cherries which start to mature.

Means of fight

A chemical treatment to eliminate these larvae appears difficult because it touches the flesh of the fruit. It is preferable to prevent while seeking to intercept the laying flies by Piège S (collars of horticultural lime) as of at the beginning of April.

Traps gravitational, known as food, are also very effective. They are posed on the cherry trees approximately five weeks before harvest. The sexual traps with Phéromone S are of a more delicate handling.
