Cuticular hydrocarbons of Triatoma infestans and T. mazzotti
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19931. 1. The cuticular hydrocarbons of Triatoma infestans and Triatoma mazzotti were examined by capillary gas-chromatography-mass spectrometry (CGC-MS). 2. 2. Hydrocarbons from both insects contained complex mixtures of n-alkanes, terminally and internally branched monomethylalkanes, dimethylalkanes and trimethylalkanes. 3. 3. T.

Control of Triatoma Infestans (Klug) with Malathion1 Concentrate2
Journal of Medical Entomology, 1975In laboratory and large-scale field tests in Argentina undiluted Malathion® ULV Concentrate Insecticide, Premium Grade (deodorized) applied in and around brick or adobe houses at 2.5 cc/m2 with a specially adapted motorized knapsack sprayer had an effective and rapid insecticidal action against Triatoma infestans , the primary vector of Chagas' disease

The intestine of Triatoma infestans. I. Cytology of the midgut
Journal of Ultrastructure Research, 1976The midgut of starved Triatoma infestans was studied by light and electron microscopy. The apical border of the intestinal cells shows microvilli in a regular array and a peculiar peritrophic membrane that forms tube like compartments around and upon the microvilli. The other cellular components are similar to those found in other hematophagus insects.

Repellency of deet to nymphs of Triatoma infestans
Medical and Veterinary Entomology, 2000SummaryThe repellency of N,N‐diethyl‐3‐methylbenzamide (deet) to Triatoma infestans (Klug) (Hemiptera: Reduviidae) was evaluated using third‐instar nymphs and a video tracking technique. Three experimental designs were used: (a) the test arena floor was divided into two halves, only one of which was treated with deet; (b) the arena floor was divided ...

Neurogenesis and occurrence of cholinesterase in eggs of Triatoma infestans
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1980Abstract 1. Eggs of T. infestans incubated at 30°C and 50% r.h. hatched in 15 days. 2. The neurogenesis of T. infestans embryo was studied. The neuroblasts appeared on the third day and the nerve cells on the fourth day. 3. The ontogenesis of cholinesterases was investigated.

Density-dependent timing of defaecation by Triatoma infestans
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1991Defaecation timing of the Triatominae vectors of Trypanosoma cruzi directly affects the transmission probability of Chagas disease to mammal hosts. Experimental studies with fifth instar nymphs of Triatoma infestans showed that defaecation time was negatively affected by blood meal size and positively affected by starvation period and bug initial ...

Field experiments of dispersive flight by Triatoma infestans
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1981Using marked male Triatoma infestans allowed to escape and fly on a little-used airport in Brazil and salt flats in Argentina, 33 of 169 flew in the former and 28 of 528 in the latter experiment. Many of the bugs which flew had been classed as poorly fed. The proportion of bugs which flew was in reasonable agreement with predictions based on laboratory

Similarity of the patterns of sensilla on the antennae of Triatoma melanosoma and Triatoma infestans
Annals of Tropical Medicine & Parasitology, 2001The patterns of sensilla on the antennae of sylvatic Triatoma melanosoma Lent, Jurberg, Galvao and Carcavallo 1994 were compared with those of three samples of Triatoma infestans (Klug 1834) - one of domestic populations in Paraguay, Bolivia, Argentina and Chile, one of the sylvatic 'dark morph' from the Bolivian Chaco, and one from sylvatic sites in ...

Hydrocarbon biosynthesis in Triatoma infestans eggs
Archives of Insect Biochemistry and Physiology, 1994AbstractTriatoma infestans eggs are shown to synthesize hydrocarbons. Radio‐gas chromatography was used to demonstrate metabolism of [1‐14C]propionate into precursor methyl‐branched fatty acids and into methyl‐branched hydrocarbons in T. infestans eggs. These reactions have not been demonstrated previously in insect eggs.

Isolation and characterization of the haemolymph lipoproteins of Triatoma infestans
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19821. Three lipoproteins differing in hydrated densities were isolated by ultracentrifugal procedures from the haemolymph of adult and fasted Triatoma infestans. 2. They are the high density lipoprotein HDL (d = 1.115-1.152) and the two very high density lipoproteins VHDL-I (d = 1.190-1.231) and VHDL-II (d = 1.245-1.260).
