The red imported fire ant is one of the notorious species of ants all over the world. The most effective control of red imported fire ant is the broadcast application of baits, i.e., fatty oil. However, to improve the sugar bait efficacy against fire ants, one of the most important ways is that understand the sugar taste mechanism of fire ant workers via feeding behavior/ethogram. Therefore, we first time described the feeding ethogram of minor fire ant workers to sucrose solution. As well as, we first time explained that, how we can block or deactivate the sensitivity of gustatory sensilla on gustatory appendages of fire ant workers (minor size, head width 0.5–0.8 mm). We used different techniques (ablation, 2–silicon components and HCL solution) for blocking the sensitivity of antennal and tarsal sensilla in in the fire ant workers. Feeding ethogram confirmed that fore legs tarsi of fire ant workers are main gustatory organ to sucrose solution. In antennal treatments, the survival % of workers without a flagellum (ablated of flagellum) was maximum as compared to silicon treated workers. In tarsal treatments, the survival % of HCL treated workers were maximum as compared to other treated workers (ablation of foreleg tarsi and silicon treated foreleg tarsi). The results implied that ablation for antennae flagellum and HCL solution for foreleg tarsi were more suitable for study the gustatory behavior of fire ant workers on the sucrose solution. This study would be more useful for the study regarding the gustatory sense of fire ant through antennal and tarsal sensilla.

红色进口火蚁是世界范围内臭名昭著的蚂蚁种类之一。防治红火蚁最有效的方法是撒播诱饵，即脂肪油。然而，要提高糖饵对火蚁的抗药性，最重要的方法之一是通过摄食行为/行为图了解火蚁工蚁的糖味机制。因此，我们首次描述了小火蚁工蚁对蔗糖溶液的摄食行为图。以及，我们第一次解释了如何阻止或停用味觉感受器对火蚁工蚁（小尺寸，头宽0.5-0.8毫米）味觉附肢的敏感性。我们使用了不同的技术（消融、2-硅成分和 HCL 溶液）来阻止火蚁工人的触角和跗骨感受器的敏感性。摄食实验证实，火蚁工蚁的前腿跗骨是蔗糖溶液的主要味觉器官。在触角处理中，与硅处理的工人相比，没有鞭毛（鞭毛消融）的工人的存活百分比最高。在跗骨治疗中，与其他接受治疗的工人（前肢跗骨消融和硅处理过的前腿跗骨）相比，接受 HCL 治疗的工人的存活率最高。结果表明触角鞭毛消融和前腿跗骨HCL溶液更适合研究火蚁工蚁对蔗糖溶液的味觉行为。本研究对于火蚁通过触角和跗骨感受器的味觉研究将更有用。在触角处理中，与硅处理的工人相比，没有鞭毛（鞭毛消融）的工人的存活百分比最高。在跗骨治疗中，与其他接受治疗的工人（前肢跗骨消融和硅处理过的前腿跗骨）相比，接受 HCL 治疗的工人的存活率最高。结果表明，触角鞭毛消融和前腿跗骨HCL溶液更适合研究火蚁工蚁对蔗糖溶液的味觉行为。本研究对于火蚁通过触角和跗骨感受器的味觉研究将更有用。在触角处理中，与硅处理工人相比，没有鞭毛（鞭毛消融）的工人的存活百分比最高。在跗骨治疗中，与其他接受治疗的工人（前肢跗骨消融和硅处理过的前腿跗骨）相比，接受 HCL 治疗的工人的存活率最高。结果表明触角鞭毛消融和前腿跗骨HCL溶液更适合研究火蚁工蚁对蔗糖溶液的味觉行为。本研究对于火蚁通过触角和跗骨感受器的味觉研究将更有用。与其他接受治疗的工人（前腿跗骨消融和硅处理的前腿跗骨）相比，HCL 治疗的工人的存活百分比最高。结果表明触角鞭毛消融和前腿跗骨HCL溶液更适合研究火蚁工蚁对蔗糖溶液的味觉行为。本研究对于火蚁通过触角和跗骨感受器的味觉研究将更有用。与其他接受治疗的工人（前腿跗骨消融和硅处理的前腿跗骨）相比，HCL 治疗的工人的存活百分比最高。结果表明触角鞭毛消融和前腿跗骨HCL溶液更适合研究火蚁工蚁对蔗糖溶液的味觉行为。本研究对于火蚁通过触角和跗骨感受器的味觉研究将更有用。
