Biosystematics of old world triatominae
Gorla, DE; Dujardin, JP; Schofield, CJ (Acta Tropica, 1997)Abstract. Morphometric analysis of Old World species of Linshcosteus and Triatoma showed the two genera to be well separated. However, although the analysis showed clear distinction between the five species of Linshcosteus, ... -
Chagas disease vector control in Central America
Schofield, CJ; Dujardin, JP (Parasitology Today, 1997)As the Southern Cone Initiative proceeds steadily towards eradication of Triatoma infestans, there is increasing interest in applying similar approaches to control Chagas disease vectors in Mexico, Central America and ... -

Cytogenetic and isozymic comparisons of two laboratory lines of Glossina palpalis gambiensis
Elsen, P; Roelants, P; De Lil, E; Dujardin, JP; Le Ray, D; Claes, Y (Annals of Tropical Medicine and Parasitology, 1994)Abstract. The genetics of two laboratory colonies of Glossina palpalis gambiensis were characterized by C-banding and isoenzyme studies. The colonies, derived from flies collected in the same locality, had different ... -
Diagnosis by isozyme methods of two cryptic species, Psychodopygus carrerai and P. Yucumensis (Diptera: Psychodidae)
Caillard, T; Tibayrenc, M; Le Pont, F; Dujardin, JP; Desjeux, P; Ayala, FJ (J. Med. Entomol., 1986)Abstract. Eleven enzyme systems were used to compare 2 cryptic species previously treated as Psychodopygus carrerai. Two enzyme systems were each completely diagnostic. Three other loci gave evidence of reproductive ... -
Enzymatic variability and phylogenetic relatedness among Triatoma infestans, T. platensis, T. delpontei and T. rubrovaria
Pereira, J; Dujardin, JP; Salvatella, R; Tibayrenc, M (Heredity, 1996)Four congeneric species of triatomine bugs, Triatoma platensis, T. delpontei, T. rubrovaria and T. infestans, were examined by multilocus enzyme electrophoresis. These four species are distributed sympatrically throughout ... -
Étude de 11 enzymes et données de génétique formelle pour 19 loci enzymatiques chez Triatoma infestans (Hemiptera: Reduviidae)
Dujardin, JP; Tibayrenc, M (Ann. Soc. Belge Med. Trop., 1985)Résumé. Onze enzymes ont été analysées par électrophorèse sur acétate de cellulose chez Triatoma infestans (Klug. 1834), vecteur principal de la maladie de Chagas. Ces onze enzymes correspondent au moins á 19 loci, dont ... -

Genética de poblaciones de triatomineos en relación a las estrategias de control de insectos vectores
Pereira, J; Dujardin, JP; Salvatella, R (Bol. Soc. Zool. Uruguay, 1995)The causative agent of Chagas disease infects more than 16 millions persons in Latin America; the resulting human chronic pathology is responsible of an important economic loss. The authors first analyze the main features ... -
Inter-relation of sylvatic and domestic transmission of Trypanosoma cruzi in areas with and without domestic vectorial transmission in Minas Gerais, Brazil
Diotaiuti, L; Pereira, AS; Loiola, CF; Fernandes, AJ; Schofield, JC; Dujardin, JP; Dias, JCP; Chiari, E (Mem. Inst. Oswaldo Cruz, 1995)During the period 1980-1986, we captured triatomine bugs and mammalian reservoir hosts from sylvatic and domestic situations in different municipalities of the State of Minas Gerais. Trypanosoma cruzi was isolated from ... -
Isoenzymes as a tool for the identification of Rhodnius species (Hemiptera: reduviidae: Triatominae)
Solano, P; Dujardin, JP; Schofield, CJ; Romana, C; Tibayrenc, M (Research and Reviews in Parasitology, 1996)ABSTRACT. Some species of Rhodnius prove difficult to separate on overt morphological characters. leading to difficulties in determining the current distribution of several of the most epidemiologically significant species. ... -
