Recursos para nematodos
Impacto económico de los nematodos
- Las pérdidas anuales de cultivos para la agricultura mundial se estiman entre $100 mil millones y $8 mil millones en EE. UU.
- Algunas de las plagas más dañinas de la agricultura tropical, subtropical y templada.
- Los nematodos agalladores (RKN) son los más destructivos del mundo
¿Qué son los nematodos?
- Pequeños animales microscópicos con forma de gusano (0,5-10 mm)
- Otras formas (redondas, en forma de pera)
- El 25 % infecta a animales y plantas
- Alta fecundidad y ciclo de vida corto
- Ocupa todos los hábitats (agua dulce, marina, salobre, terrestre)
- Dominante numérico 80 000 spp
