Proteinase and gelatinolytic properties of a triatoma infestans extract

Allergologia et Immunopathologia, 2004
An extract of Triatoma infestans has previously been demonstrated to produce specific IgG and IgE both in animals and in atopic humans with rhinitis/asthma as well as hypersensitivity pneumonitis in guinea pigs aerosolized with T. infestans. We attempted to determine whether the antigen or antigens responsible belonged to the protease group, as occurs ...

Impregnated Netting Slows Infestation by Triatoma infestans [PDF]

The American Journal of Tropical Medicine and Hygiene, 2008
We used sentinel animal enclosures to measure the rate of infestation by the Chagas disease vector, Triatoma infestans, in an urban community of Arequipa, Peru, and to evaluate the effect of deltamethrin-impregnated netting on that rate. Impregnated netting decreased the rate of infestation of sentinel enclosures (rate ratio, 0.23; 95% confidence ...

Host‐foraging stable flies, Stomoxys calcitrans, are preferentially attracted to objects with both visual and thermal host‐like characteristics

Entomologia Experimentalis et Applicata, Volume 172, Issue 2, Page 111-122, February 2024.
To study the effects of thermal cues on foraging stable flies, we tested the hypothesis that flies preferentially alight on objects with host‐like temperature, and on objects with both visual and thermal host‐like cues. Flies preferred host‐like temperatures when in foraging mode, but not when offered only infrared stimuli.

Biological activity of Schinus molle on Triatoma infestans

Fitoterapia, 2006
Hexanic extracts from leaves and fruits of Schinus molle were tested for repellent and insecticidal properties against first instar nymphs and eggs of Triatoma infestans, the vector of Chagas' disease. Leaf and fruit extracts were highly repellent for first nymphs. Fruit extracts had also ovicidal activity.

The residual efficacy of a cypermethrin pour-on formulation applied on goats on the mortality and blood intake of Triatoma infestans [PDF]

, 2012
Triatoma infestans is the main vector of Trypanosoma cruzi, the aetiological agent of Chagas disease in the Gran Chaco region of South America. As a frequent blood meal source for triatomine bugs, domestic goats play a key role in the eco-epidemiology of

Estudo comparado do ciclo evolutivo de triatomíneos a duas temperaturas Comparison of life cycles of triatominae according to changes in temperature

Memorias do Instituto Oswaldo Cruz, 1989
We studied the life cicle of several triatominae species: Dipetalogaster maximus (Uhler, 1894); Panstrongylus herreri Wygodzinsky, 1948; Panstrongylus megistus (Burmeister, 1835); Rhodnius ecuadoriensis Lent & Leon, 1958; Rhodnius nasutus Stal, 1859 ...

Estudo sobre a utilização de Rhodnius neglectus para xenodiagnósticos realizados em marsupiais (Didelphis) The utilization of Rhodnius neglectus in xenodiagnosis: a study performed on opossums

Revista de Saúde Pública, 1976
Em marsupiais (Didelphis), portadores de infecção natural pelo T. cruzi, procurou-se levar a efeito xenodiagnósticos com o emprego de ninfas de Rhodnius neglectus e de Triatoma infestans e através do exame periódico de lotes formados por cinco insetos ...

Chromosomal location of heterochromatin and 45S rDNA sites in four South American triatomines (Heteroptera: Reduviidae)

Comparative Cytogenetics, 2010
The Triatominae are distributed in Brazilian regions and are the vector of Chagas disease. This group is also characterized by lower karyotype variability, occurrence of holokinetic chromosomes and inverted meiosis of the sex chromosomes.

C-heterochromatin polymorphism in holocentric chromosomes of Triatoma infestans (Hemiptera: Reduviidae)

, 1992
This is the first report of intraspecific variation of C-bands in Heteroptera, described in natural populations of Triatoma infestans (Hemiptera: Reduviidae), the main vector of Chagas disease in Uruguay.
