Orcokinins regulate the expression of neuropeptide precursor genes related to ecdysis in the hemimetabolous insect Rhodnius prolixus
(Pergamon-Elsevier Science Ltd, 2018-07)
Ecdysis is a vital process for insects, during which they shed the old cuticle in order to emerge as the following developmental stage. Given its relevance for survival and reproduction, ecdysis is tightly regulated by ...

The primary objective of this study was to estimate the prevalence of this disease in women of childbearing age and children treated at health centres in underserviced areas of the city of Buenos Aires. Demographic and ...
Allatotropin modulates myostimulatory and cardioacceleratory activities in Rhodnius prolixus (Stal)
(Public Library of Science, 2015-04)
Haematophagous insects can ingest large quantities of blood in a single meal and eliminate high volumes of urine in the next few hours. This rise in diuresis is possible because the excretory activity of the Malpighian ...
Juvenile hormone mediates lipid storage in the oocytes of Dipetalogaster maxima
(Elsevier, 2020-11-16)
Triatomines are vectors of Chagas disease and important model organisms in insect physiology. “Kissing bugs” are obligatory hematophagous insects. A blood meal is required to successfully complete oogenesis, a process ...

Os triatomíneos, insetos hematófagos estritos em todas as fases da vida, conhecidos popularmente como “barbeiros” ou “chupanças”, pertencem à subfamília Triatominae (Heteroptera – Reduviidae) e são importantes vetores da ...
Lizards and rabbits may increase Chagas infection risk in the Mediterranean-type ecosystem of South America
(Nature, 2020)
Studies of host-parasite relationships largely benefit from adopting a multifactorial approach, including the complexity of multi-host systems and habitat features in their analyses. Some host species concentrate most ...
Aspectos parasitológicos y epidemiológicos de los donantes de sangre seropositivos para Trypanosoma cruzi, en un hospital universitario
(Sociedad Médica de Santiago, 2007)
Background: After the interruption of the transmission of Chagas
disease via vector insects in Chile, there is little available epidemiological information about this
parasitosis in blood banks. Aim: To update the rates ...
Insecticide Resistance Mechanisms in Triatoma infestans (Reduviidae: Triatominae): The Putative Role of Enhanced Detoxification and Knockdown Resistance (kdr) Allele in a Resistant Hotspot from the Argentine Chaco
(Entomological Society of America, 2020-05)
Chagas disease affects around 6 million people in the world, and in Latin America, it is mainly transmitted by the kissing bug. Chemical control of the vector with pyrethroid insecticides has been the most frequently used ...
