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。
Objective To investigate the preference of different species of termites in Taiwan for the production of standardized termite baits. Methods The indoor bioassay method was used to investigate the feeding of 6 kinds of cellulose and 14 kinds of cellulose mixture from Taiwan milk termites. Results Among the six kinds of cellulose tested, the most preferred microcrystalline cellulose of Taiwan milk termites was 1 561.3 mg, followed by lignocellulose and cellulose acetate, with the feeding rates being 501.2 and 53.8 mg respectively. Among 14 kinds of cellulose mixtures, Taiwanese termites prefer the mixture of No.7, No.8 and No.9. The feeding amounts are 214.0, 200.8 and 176.7 mg. Except for microcrystalline cellulose, cellulose acetate, carboxymethyl cellulose, carboxyethyl cellulose and carboxypropyl cellulose, other cellulose are susceptible to mildew. Conclusion Taiwan termites prefer to eat microcrystalline cellulose, it is proposed to use it as a material development and production of termites bait.
