Oogenesis and egg development in triatomines: a biochemical approach [PDF]

Anais da Academia Brasileira de Ciências, 2005
In triatomines, as well as in other insects, accumulation of yolk is a process in which an extra-ovarian tissue, the fat body, produces yolk proteins that are packed in the egg. The main protein, synthesized by the fat body, which is accumulated inside the oocyte, is vitellogenin. This process is also known as vitellogenesis.

Sugar feeding in triatomines: a new perspective for controlling the transmission of Chagas disease

Frontiers in Physiology
Introduction: Triatomines are vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. Currently, there is no vaccine against this disease. Thus, control of the insect vector population is the main strategy available to reduce the number of

Proteases of haematophagous arthropod vectors are involved in blood-feeding, yolk formation and immunity : a review [PDF]

, 2017
Ticks, triatomines, mosquitoes and sand flies comprise a large number of haematophagous arthropods considered vectors of human infectious diseases. While consuming blood to obtain the nutrients necessary to carry on life functions, these insects can ...

Natural infection by Trypanosoma cruzi in triatomines and seropositivity for Chagas disease of dogs in rural areas of Rio Grande do Norte, Brazil.

Revista da Sociedade Brasileira de Medicina Tropical, 2018
INTRODUCTION Chagas disease is caused by the protozoa Trypanosoma cruzi. Its main reservoir is the domestic dog, especially in rural areas with favorable characteristics for vector establishment and proliferation.

Land Use Change and Infectious Disease Emergence

Reviews of Geophysics, Volume 63, Issue 2, June 2025.
Abstract Major infectious diseases threatening human health are transmitted to people from animals or by arthropod vectors such as insects. In recent decades, disease outbreaks have become more common, especially in tropical regions, including new and emerging infections that were previously undetected or unknown. Even though there is growing awareness

Phylogenetic approach to the study of Triatomines (Triatominae, Heteroptera)

Brazilian Journal of Biology
Triatomines are insects belonging to the Hemiptera order, Heteroptera suborder, Reduviidae family and Triatominae subfamily. All members of this subfamily are hematophagous. Triatomines evolved from Reduviidae predators and they are probably polyphyletic

A simplified method for sample collection and DNA isolation for polymerase chain reaction detection of Trypanosoma rangeli and Trypanosoma cruzi in triatomine vectors

Memorias do Instituto Oswaldo Cruz, 2000
Due to the overlapping distribution of Trypanosoma rangeli and T. cruzi in Central and South America, sharing several reservoirs and triatomine vectors, we herein describe a simple method to collect triatomine feces and hemolymph in filter paper for ...

Bacterial community composition in the salivary glands of triatomines (Hemiptera: Reduviidae)

PLoS Neglected Tropical Diseases, 2018
Background Chagas disease is caused by the parasite Trypanosoma cruzi and is transmitted through triatomines (Hemiptera: Reduviidae). In the last year, many studies of triatomine gut microbiota have outlined its potential role in modulating vector ...

Fluralaner treatment of chickens kills the southern house mosquito, Culex quinquefasciatus

Medical and Veterinary Entomology, Volume 39, Issue 2, Page 385-392, June 2025.
Chickens treated with fluralaner, fenbendazole or ivermectin did not repel Culex quinquefasciatus from feeding. The mortality of Culex quinquefasciatus feeding on fluralaner‐treated chickens was significantly higher than that of those fed on control chickens at 3 and 7 days post‐treatment.
