A study was performed to investigate the effects of the Insect Growth Regulator fenoxycarb on the symbiotic fauna of the lower termite Reticulitermes lucifugus. Experimental units consisting of 30 workers were placed in plastic Petri dishes lined with filter paper disks treated with different concentrations of fenoxycarb. Termite symbionts were extracted from randomly chosen termites and were identified as Dynenympha sp, Pyrsonympha sp, Spirotriconympha flagellata and Trychonympha agilis. The flagellates were counted by species in termites just extracted from native logs (representing the hindgut fauna in natural conditions), and after 10 and 21 days from the exposure to filter paper disks. Results showed that fenoxycarb negatively affected symbiotic flagellate population levels, with a progressive significant reduction of their abundance and disappearance of Pyrsonympha sp and Trychonympha agilis.

Abstract

A study was performed to investigate the effects of the Insect Growth Regulator fenoxycarb on the symbiotic fauna of the lower termite Reticulitermes lucifugus. Experimental units consisting of 30 workers were placed in plastic Petri dishes lined with filter paper disks treated with different concentrations of fenoxycarb. Termite symbionts were extracted from randomly chosen termites and were identified as Dynenympha sp, Pyrsonympha sp, Spirotriconympha flagellata and Trychonympha agilis. The flagellates were counted by species in termites just extracted from native logs (representing the hindgut fauna in natural conditions), and after 10 and 21 days from the exposure to filter paper disks. Results showed that fenoxycarb negatively affected symbiotic flagellate population levels, with a progressive significant reduction of their abundance and disappearance of Pyrsonympha sp and Trychonympha agilis.
