LABORATORY EVALUATION OF TRANSFER EFFECT OF TERMITICIDES AS A SLOW-ACTING TREATMENT AGAINST SUBTERRANEAN TERMITE COPTOTERMES GESTROI (ISOPTERA: RHINOTERMITIDAE)

Abstract

Termiticides containing fipronil, imidacloprid and indoxacarb were examined to cause the mortality among the donor termites (exposed to termiticides) to recipient termites (unexposed to termicides) of Coptotermes gestroi. The results showed that fipronil killed the donor termite faster compared to indoxacarb and imidacloprid. At 100 and 1000 ppm, fipronil caused high mortality on termite C. gestroi on the third day for both concentrations where the mortality was 100%. The range of the mean percent mortality of recipient termites was different compared to the range of mean mortality of donor termites.  The results show that the range of the mean mortality for recipient termites were from 0.35 to 16.05 for imidacloprid, 4.5 to 39.6 for fipronil and 4.2 to 15.75 for indoxacarb. As for the donor termites, the range of the mean mortality was 0.7 to 2.5, 1.8 to 4.75 and 0.85 to 2.95 for imidacloprid, fipronil and indoxacarb respectively.
