Botto Mahan, Carezza; Cattan Ayala, Pedro; Canals Lambarri, Mauricio (2002)In spite of extensive evidence showing an association between host stimuli and insect finding behaviour, the importance of carbon dioxide in attracting Triatominae is not entirely understood. We assessed the potential of ...

Botto Mahan, Carezza; Ramírez, Patricia A.; Ossa, Carmen Gloria; Medel Contreras, Rodrigo; Ojeda-Camacho, Manuel; González, Alejandra V. (2011)Floral damage can reduce flower attractiveness for pollinator service. However, the reproductive impact of flower herbivory may be contingent on a petal that is damaged. Flowers having nectar guides are expected to suffer ...

Yáñez Meza, Andrea; Landaeta Aqueveque, Carlos; Quiroga, Nicol; Botto Mahan, Carezza (Brazilain Coll Veterinary Parasitology, 2019)Helminth parasites are still not a well-known component of animal biodiversity. In this study, we describe and compare the endoparasite assemblages of three native rodent species from a semiarid Mediterranean ecosystem. A ...

Campos, Ricardo; Torres Pérez, Fernando; Botto Mahan, Carezza; Coronado, Ximena; Solari Illescas, Aldo (Elsevier, 2013)The hematophagous Hemiptera of the subfamily Triatominae are a very diverse group with a variety of morphs, behaviors and distributions. They have great epidemiological importance because many of its members are vectors ...

Coronado, Ximena; Rozas, Marlene; Botto Mahan, Carezza; Ortíz, Sylvia; Cattan Ayala, Pedro; Solari Illescas, Aldo (2009)The sylvatic transmission cycle of Chagas disease in Chile is composed of wild mammals and insects of the genus Mepraia. We determined infection rates and Trypanosoma cruzi genotypes in Mepraia spinolai. We collected 227 ...

Botto Mahan, Carezza; Pohl, Nélida; Medel Contreras, Rodrigo (2004)Most studies assessing the importance of developmental instability of floral characters for pollinator visits and plant fitness have focused on the fluctuating asymmetry (FA) of the corolla phenotype. The importance of ...

Medel Contreras, Rodrigo; Botto Mahan, Carezza; Arroyo, Mary T. K. (Ecological Society of America, 2003)Mimulus luteus (Scrophulariaceae) is a perennial herb occurring in the South American Andes that shows a wide variation in the size and shape of a red spot on the lower lobe of the yellow flower. We describe the preference ...

Medel Contreras, Rodrigo; Botto Mahan, Carezza; Smith Ramírez, Cecilia; Méndez, Marco; Ossa, Carmen G.; Caputo, Luciano; González, Wilfredo L. (2002)We present quantitative information on the natural history of a host-parasite interaction that consists on the holoparasitic mistletoe Tristerix aphyllus (Loranthaceae) and its cacti host species. More specifically, we ...

Botto Mahan, Carezza; Acuña Retamar, Mariana; Campos, Ricardo; Cattan Ayala, Pedro; Solari Illescas, Aldo (2009)Trypanosoma cruzi, the etiologic agent of Chagas disease, presents a complex life cycle, cycling between reduviid vectors and wild and domestic mammals. The European rabbit is an introduced species in America, but its role ...

Ihle Soto, Camila Adriana; Costoya, Eduardo; Correa, Juana P.; Bacigalupo, Antonella; Cornejo-Villar, Berenice; Estadella, Viviana; Solari, Aldo; Ortiz, Sylvia; Hernández, Héctor J.; Botto Mahan, Carezza; Gorla, David E.; Cattan Ayala, Pedro (Public Library of Science, 2019)Background Trypanosoma cruzi is a protozoan parasite that is transmitted by triatomine vectors to mammals. It is classified in six discrete typing units (DTUs). In Chile, domestic vectorial transmission has been interrupted; ...

Cabe, A. Mc; Yañez, F.; Pinto, R.; López, A.; Ortiz, S.; Muñoz San Martín, Catalina; Botto Mahan, Carezza; Solari, A. (Elsevier B.V., 2019)Chagas disease is caused by Trypanosoma cruzi. Vector survival is an important variable affecting vectorial capacity to determine parasite transmission risk. The aims of this study are to evaluate vector survival under ...

Estay Olea, Daniela; Correa, Juana; Bona, Sophie de; Bacigalupo, Antonella; Quiroga, Nicol; San Juan, Esteban; Solari Illescas, Aldo; Botto Mahan, Carezza (Elsevier, 2020)Hematophagous insects exhibit complex behaviour when searching for blood-meals, responding to several host stimuli. The hematophagous insect Mepraia spinolai is a wild vector of Trypanosoma cruzi, causative agent of Chagas ...

Toledo, Andrea; Vergara, Fernanda; Campos, Ricardo; Botto Mahan, Carezza; Ortiz, Sylvia; Coronado, Ximena; Solari Illescas, Aldo (The American Society of Tropical Medicine and Hygiene, 2013)We evaluated Trypanosoma cruzi infection in 397 wild Mepraia gajardoi specimens from five coastal localities in northern Chile by detection of minicircle DNA by polymerase chain reaction. The wild capture sites were ...
