Abstract

Objective This experiment used Coptotermes formosanus Shiraki as selected insect to find suitable preservatives and its optimum concentration in termite artificial bait. Methods The experiment compared the mildew- proof effect of four preservatives, Sodium benzoate, Potassium sorbate, Citral and Propylparaben on termite artificial bait outdoor, and took choice-feeding and no-choice-feeding experiments to compare the effect of Sodium benzoate, Potassium sorbate, and Propylparaben on the termite feeding if added into the bait. Results The addition of Citral did not efficiently affect the mildew of the bait, while other three preservatives inhibited the mildew efficiently; the heavy feeding by termites on baits that contained 0.05% Sodium benzoate, 0.1% Potassium sorbate and 0.025% Propylparaben were 0.45, 0.28, 0.34 g, and all had no effect on the termite survival rate. Conclusion The 0.05% sodium benzoate is the most suitable preservative for termite artificial bait.
