Resumen
Se analizó el comportamiento de consumo de tres especies de termitas (Cortaritermes fulviceps, Nasutitermes aquilinus y Nasutitermes corniger) mediante bioensayos de laboratorio, utilizando maderas de cuatro especies arbóreas comúnmente utilizadas en estructuras y muebles en el noreste argentino (Eucalypus grandis, Pinus elliottii, Neltuma alba y Cordia americana). El consumo de madera de cada especie de termita se midió por la diferencia entre el peso seco inicial y final de las muestras, utilizando una escala cualitativa. Los cuatro tipos de madera fueron consumidos por las tres especies de termitas. Los consumos de C. fulviceps y N. aquilinus fueron reducidos y sus daños se categorizaron como leves o moderados, por lo que ambas termitas podrían considerarse como plagas urbanas ocasionales. Por el contrario, N. corniger produjo los daños más importantes en todas las maderas, confirmando el estatus de plaga estructural severa y la necesidad de un monitoreo y control de esta especie.
The consumption behavior of three termite species (Cortaritermes fulviceps, Nasutitermes aquilinus, and Nasutitermes corniger) was analyzed through laboratory bioassays, using wood from four tree species commonly utilized in structures and furniture in northeastern Argentina (Eucalyptus grandis, Pinus elliottii, Neltuma alba, and Cordia americana). Wood consumption by each termite species was measured by the difference between the initial and final dry weight of the samples, and by using a qualitative scale. All four wood types were consumed by the three termite species. The consumption by C. fulviceps and N. aquilinus was reduced, and the damage was categorized as slight or moderate; therefore, both termites could be considered occasional urban pests. Conversely, N. corniger produced the most significant damage in all wood types, confirming its status as a severe structural pest and the need for monitoring and control of this species.
