Bloodmeal analysis of Triatoma dimidiata collected in peridomestic habitats of western Panama showed that avian feedings comprised 25% of this species' host selections; opossums, the principal reservoir of Chagas' disease in the republic, were not among mammalian feedings. These findings may account for the low infestation rates of Trypanosoma cruzi in the bugs and the hypoendemicity of Chagas' disease in western Panama.
对在巴拿马西部家周环境中采集的二色锥蝽进行的血餐分析表明，鸟类血液占该物种宿主选择的25%；负鼠是该国恰加斯病的主要储存宿主，但在哺乳动物血液选择中未被发现。这些发现可能解释了锥蝽中克氏锥虫感染率低以及巴拿马西部恰加斯病低流行率的原因。
