Com ho fem? Utilitzem unes trampes de forat molt senzilles col\u00b7locades al terra: s\u2019introdueix un tub de PVC en un petit forat, dins del qual es col\u00b7loca un got amb propilenglicol (una subst\u00e0ncia que conserva els insectes). Aix\u00f2 actua com a trampa, on hi cauen els insectes que es mouen pel s\u00f2l. Despr\u00e9s d\u2019una setmana, es recullen les trampes i els insectes atrapats es conserven en etanol per al seu an\u00e0lisi al laboratori.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/lifeconnectricoti.com\/wp-content\/uploads\/2025\/07\/WhatsApp-Image-2025-06-03-at-12.11.31-2-3-1024x768.jpeg\" alt=\"\" class=\"wp-image-3072\" srcset=\"https:\/\/lifeconnectricoti.com\/wp-content\/uploads\/2025\/07\/WhatsApp-Image-2025-06-03-at-12.11.31-2-3-1024x768.jpeg 1024w, https:\/\/lifeconnectricoti.com\/wp-content\/uploads\/2025\/07\/WhatsApp-Image-2025-06-03-at-12.11.31-2-3-300x225.jpeg 300w, https:\/\/lifeconnectricoti.com\/wp-content\/uploads\/2025\/07\/WhatsApp-Image-2025-06-03-at-12.11.31-2-3-768x576.jpeg 768w, https:\/\/lifeconnectricoti.com\/wp-content\/uploads\/2025\/07\/WhatsApp-Image-2025-06-03-at-12.11.31-2-3.jpeg 1296w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><strong>Figura 2.<\/strong> Col\u00b7locaci\u00f3 de trampes pitfall a les parameres de Molina d\u2019Arag\u00f3n.<\/p>\n\n\n\n<p>Aquest treball de camp es va realitzar durant els mesos de maig i juny en tres \u00e0rees clau per a l\u2019esp\u00e8cie que formen part del projecte: <strong>Hoces del Durat\u00f3n i Riaza <\/strong>(Seg\u00f2via), <strong>Parameras de Molina<\/strong> (Guadalajara) i <strong>Valeria, Moya i Pedro Izquierdo <\/strong>(Conca).
