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.

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

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

Blood-feeding performance of nymphs and adults of Triatoma brasiliensis on human hosts

Acta Tropica, 2003
The blood-feeding behaviour of nymphs and adults of Triatoma brasiliensis fed on the forearm of human volunteers was studied by electronic monitoring of the cibarial pump. Parameters of total contact time (TT), initial weight (IW), weight gain (WG), ingestion rate (IR), pump frequency (F), quantity of liquid ingested per cibarial pump stroke (QLC) and ...
