Lipoprotein Lipase in the Fat Body of Triatoma brasiliensis

Archives Internationales de Physiologie et de Biochimie, 1976
Lipoprotein lipase activity was detected and characterized in the fat body of Triatoma brasiliensis one of the vector of Chagas' disease. The enzyme activity was close to a free fatty acid production of 47 mumol FFA mg protein-1-h-1 when assayed in the complete system. 2. The enzyme presented maximum activity at pH 8.5.

The use of aggregation signals by Triatoma brasiliensis (Heteroptera: Reduviidae)

Acta Tropica, 2007
Triatoma brasiliensis is considered the main vector of Chagas disease in the semiarid zones of North-eastern Brazil. In this work, we describe the spatial pattern of defecation in T. brasiliensis and the spatial relationship of faeces with the shelters of these bugs. Afterwards, we analyse the attraction response of T.

Influence of the Blood Meal Source on the Development ofTriatoma infestans,Triatoma brasiliensis,Triatoma sordida,andTriatoma pseudomaculata(Heteroptera, Reduviidae)

Journal of Medical Entomology, 2000
The objective of this study was to determine the influence of the blood meal source on the life cycle and reproductive development of female Triatoma infestans (Klug, 1834), Triatoma brasiliensis Neiva, 1911, Triatoma sordida (Stal, 1859), and Triatoma pseudomaculata Corrga & Espfinola, 1964. In all triatomine species studied the life cycle was shorter

Comparison of feeding behaviour of Triatoma infestans, Triatoma brasiliensis and Triatoma pseudomaculata in different hosts by electronic monitoring of the cibarial pump

Journal of Insect Physiology, 2000
Feeding behaviour of Triatoma infestans, T. brasiliensis and T. pseudomaculata on pigeons and mice was compared by electronic monitoring of the cibarial pump. The methodology developed permits the study detailed of triatomine feeding behaviour using an artificial feeder as well as on live hosts. T. infestans was the species that fed most rapidly on the

Relative humidity and water loss in Triatoma brasiliensis

Physiological Entomology, 2005
Abstract.  The effect of the relative humidity (RH) of the environment on water loss is studied in Triatoma brasiliensis . Starved or recently fed early stages of T. brasiliensis are exposed to 15, 37, 46 and 73% RH.

Cross-mating experiments detect reproductive compatibility between Triatoma sherlocki and other members of the Triatoma brasiliensis species complex

Acta Tropica, 2013
Phylogenetic approaches based on mitochondrial DNA variation (fragments of Cyt B and 16S ribosomal RNA) have revealed Triatoma sherlocki as the most recent species addition to the Triatoma brasiliensis species complex; a monophyletic group which includes T. brasiliensis, Triatoma melanica, and Triatoma juazeirensis. T.

Genetic variability of Triatoma brasiliensis (Hemiptera: Reduviidae) populations.

Journal of medical entomology, 2001
Isoenzymes, random amplified polymorphic DNA (RAPD), and morphometry were used to compare genetic variability within and between three populations of Triatoma brasiliensis Neiva, 1911 from northeast Brazil. The isoenzyme profiles were identical for the three populations, whereas the complex RAPD patterns allowed clear discrimination between the three ...
