Abstract:

Objective In order to provide the cellulose materials for the standard production of bait for the control of Coptotermes formosanus, the preference of C. formosanus to various celluloses were determined in laboratory. Methods The preference of C. formosanus to 6 kinds of celluloses and 14 kinds of cellulose mixtures were determined by the bioassay method. Results The cellulose mostly preferred by the workers of C. formosanus was avicel(1 561.3 mg was consumed), followed by lignocellulose(501.2 mg)and cellulose acetate(53.8 mg). Among 14 mixtures, the C. formosanus workers preferred the mixture of No. 7, No. 8 and No. 19, of which weight was 214.0, 200.8 and 176.7 mg consumed by termites, respectively. Except avicel, cellulose acetate, carboxymethyl cellulose, carboxyethyl cellulose, and hydroxypropyl cellulose, other celluloses got easily infested by fungi during the test. Conclusion Coptotermes formosanus like to feed on avicel, this cellulose has the potential to be as the material of commercial termite bait.
