Precauciones para una nueva plaga en la castaña

La "vespeta" o "avispilla" del castaño (Dryocosmus kuriphilus) es un pequeño himenóptero de origen asiático perteneciente a la familia Cynipidae,

Precautions must be made for a new pest invading chestnut crops.The "vespeta" or "avispilla" chestnut (Dryocosmus kuriphilus) crops are being invaded by a small wasp that belongs to the Asian Cynipidae family. It is considered a quarantine organism in the European Union. This insect may turn out to be one of the most harmful to chestnut trees and reduce their fruiting and can even cause the death of the affected trees. It is harmful to various species of chestnut, including the European (Castanea sativa).

It has recently been detected in Granada and in its proximity so there are fears that it will extend into our province, where more than 4,000 hectares of chestnut trees are able to reach a harvest of between 4 and 5 million kilos. The best way to prevent this dreaded plague, asserted by the technicians at Asaja Malaga, is to recommend to the producers that they only purchase organisms and plants that are certified to be free of these pests.

Originally Vespeta was detected in America in 1974 and Europe in 2002, particularly in Italy. Subsequently, it has been detected in different European states such as France, Slovenia, Switzerland, Hungary, Croatia, Netherlands, Slovakia, Germany, Czech Republic. This organism was included in 2003 as an organism to be quarantined by the European Union. In 2012 it was detected in Spain, particularly in Catalonia. Recently, in a nursery in the province of Granada, the pest has been detected in a consignment of chestnuts, whose spring sprouting was affected. For the non­proliferation of focus, Plant Health Services Board of Andalusia, in addition to the destruction of the whole consignment, have identified a barrier zone (cordon) and an observation area, applying the rules. The presence of this pest in Spain implies the need for caution when selecting plant materials, and to not import anything from the infected areas.

"Unfortunately, every year we see how people are still collecting seeds or buying plants from our neighboring countries, so it is our duty to give warning to all those who carry out such practices as they are seriously endangering our chestnut production. It is also important that farmers notify the District Agricultural Offices of any possible outbreak for immediate control ", insist technicians of Asaja Malaga.
