Textile Physical Barriers against the Chestnut Gall Wasp Dryocosmus kuriphilus

Dryocosmus kuriphilus Yasumatsu is a species originating from China that, during the 20th century, has spread rapidly throughout many countries, affecting mainly different of genus Castanea spp. In fact, it considered to be most important pest chestnut trees (Castanea sativa Miller), causing significant production losses. The adoption complementary measures chemical and biological controls would contribute control pest. this sense, use textile physical barriers could prevent rapid among centers. Therefore, objective study define characteristics that protects young plants have been produced in nurseries. For purpose, some commercial textiles selected based on morphometric characterization these accurately measured order compare their dimensions with those insects. Finally, tests carried out measure efficacy under laboratory conditions, controlling air velocity temperature. results reveal general, theoretical may not good predictor practical results. A fully effective screen found against its design can used as starting point for new, more optimized designs.
