我们用染有苏丹红7B 染料的滤纸来喂食台湾地下白蚁(即 Coptotermcs formosanuo Shiraki)的工蚁。染料被摄食后,用分光光度计能测定吸入的染料量。不管喂食的间隔天数如何,这种染料经白蚁相互交哺达一定程度后,不会从一只白蚁身上转移到另一只白蚁身上。在控制喂食的九天后,留在白蚁蚁体组织中的染料量,与给白蚁喂食有染料的滤纸 We used filter paper dyed with Sudan 7B to feed workers in Taiwan’s underground termites (Coptotermcs formosanuo Shiraki). After the dye is ingested, the amount of dye drawn in can be measured with a spectrophotometer. Regardless of the number of days of feeding, the dye will not migrate from one termite to another after it has been crossed in with termites to some extent. After nine days of feeding control, the amount of dye left in the termite ants’ tissues was compared with the amount of dye fed to the termites
