Sèquia dels Reguers

The Sèquia dels Reguers receives water from the Barranc de la Conca and the Barranc de la Vall Cervera, which join at the height of the Xerta - Sénia channel and passes through the town of Els Reguers to Jesús, where the Barranc dels Molins empties, with more of 10 km of route.

In its upper part, the section that presents problems due to black fly larvae is the one that comes from the Barranc de la Conca. The stretch of ditch that comes from the Vall Cervera is buried, so black fly larvae cannot develop.

Throughout the year it transports water that is used for irrigation of the area, and although in winter time it has water throughout its journey, in summer, the irrigation needs mean that water has to be distributed in shifts, and the section The end of the canal, below the Reguers population, is often dry, thus making it impossible for the development of simulid larvae.

Their passage through the interior of Els Reguers population and through more or less urbanized areas make the tasks of controlling these insects in this infrastructure more important than in habitats further away from populated areas.

Sampling: sampling is done by brushing the bottom of the ditch to help detach any larvae that may be attached. For this purpose, a brush and a net with a 500 micron mesh are available, with which the larvae are collected. The sediment that is collected with the mesh is placed in a basin with water and the larvae that have been collected are counted. Depending on the larvae that appear and their stage of development, a treatment is decided.
