Efficacy of altriset® on the tropical arboreal termite, nasutitermes corniger (isoptera: Termitidae: Nasutitermitinae)

Abstract

Altriset (chlorantraniliprole) was toxic to the higher termite, Nasutitermes corniger, in exposures to 500 ppm aqueous spray and to 50 or 100 ppm forced exposures on treated sand. Depending on the treatment, complete mortality occurred between 25 and 161 hours post-treatment with sand treatments causing faster mortality than spray applications. Although this species does not exhibit the same soil tunneling/excavating behavior as subterranean termites, the direct spray and treated sand results provide a realistic estimation of Altriset efficacy after direct treatment to nest sites or Nasutitermes spp. foraging areas.
