Effectiveness of Essential Oils and Their Components Against Triatoma infestans (Hemiptera: Reduviidae)

AbstractPurpose of ReviewChagas disease is a neglected tropical disease caused by the protozoan parasite calledTrypanosoma cruzi affecting 7 –8 million people in the world.Triatoma infestans (Klug) (Hemiptera: Reduviidae) is the main vector of Chagas disease in the southern cone of South America. Genetic evidence indicates thatT. infestans originated in the Cochabamba region, Sucre, in Central Bolivia, where there are jungle sites of this species, and from which the domestic species is believed to derive, currently distributed in Chile, Argentina, Brazil, Bolivia, and Paraguay. Chemical control of the vector by spraying dwellings with pyrethroids has been the most widely used strategy to reduce the incidence of this endemic disease. The long-term use of pyrethroid insecticides inT. infestans control campaigns has led to the development of resistance in treated populations. Recently, there has been great interest in the use of botanical products as new alternatives to synthetic insecticides. Essential oils (EOs) seem to be good candidates due to lesser mammalian toxicity and persistence in the environment. In this review, we summarize recent data on toxicity of EOs and their compounds againstT. infestans.Recent FindingsA total of 12 research articles from different sources were reviewed and analyzed to compare the effectiveness of the studied EOs and monoterpenes on kissing bugs. The monoterpenes and the EOs reported in the experimental procedures and their effectiveness aga...
