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.

摘要：

目的 探讨台湾乳白蚁对不同纤维素的偏好性，为生产标准化白蚁饵剂提供依据。方法 采用室内生物测定方法调查台湾乳白蚁取食6种纤维素及14种纤维素混合物的情况。结果 在供试的6种纤维素中，台湾乳白蚁最喜食微晶纤维素，取食量为1 561.3 mg，其次为木质纤维素和醋酸纤维素，取食量分别为501.2和53.8 mg。在14种纤维素混合物中，台湾乳白蚁较喜食7、8和19号混合物，取食量依次为214.0、200.8和176.7 mg。除微晶纤维素、醋酸纤维素、羧甲基纤维素、羧乙基纤维素和羧丙基纤维素外，其他纤维素均易霉变。结论 台湾乳白蚁较喜食微晶纤维素，建议用其作为材料开发生产白蚁饵剂。
