Insect Fluctuating Asymmetry: An Example in Bolivian Peridomestic Populations of Triatoma infestans (Klug, 1834) (Hemiptera: Reduviidae)

Fluctuating asymmetry (FA) is a morphometric tool used to measure developmental instability in organisms which have been exposed stress or other adverse conditions. Phenotypic variability response stressors are the result of interactions between genomes and environment, acting noisy system. Most bilateral symmetry with repetition structures different positions orientations; asymmetrical variation has morphological associated insecticide application inducing disturbances endocrinal system product chemicals. Triatoma infestans (is main vector Chagas disease South America. The availability food sources varies for populations T. living habitats; insects that inhabit intradomicile feed preferentially on human blood, whereas develop peridomicile blood mammals birds. following research evaluate FA ecotopes two geographical areas Chuquisaca Bolivia; Yamparáez/Sotomayor high inter-Andean valleys Huacaya/Imbochi boreal Chaco CIPEIN laboratory strain population. A combination advanced morphometrics tools multivariate analysis were quantify levels produced by pyretroid near peridomiciles Bolivia. Populations from found higher environmental conditions such as low temperatures avoid greater permanence habitat more exposition insecticide. better understanding these will allow researchers implement public policies regulate applications understand how certain adapt multiple stressors.
