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.

Isozyme evidence of lack of speciation between wild and domestic triatoma infestans (Heteroptera: reduviidae) in Bolivia
Dujardin, JP; Tibayrenc, M; Venegas, Enrique; Maldonado, L; Desjeux, P; Ayala, FJ (J. Med. Entomol., 1987-01)Abstract . Wild and domestic Triatoma infestans from the Cochabamba region of Bolivia were virtually identical at l9 gene loci coding for enzymes. No allele was distinctive of either the wild or the domestic populations. ... -
Linkage disequilibrium in natural populations of Trypanosoma cruzi (Flagellate), the agent of Chagas'disease
Zhang, Qifa; Tibayrenc, M; Ayala, FJ (J. Protozool., 1988)ABSTRACT. We have studied linkage disequilibrium in natural populations of Trypanosoma cruzi, the agent of Chagas' disease, by analyzing (i) a set of 524 stocks from the whole geographical range of the ... -
Trypanosoma cruzi populations : more clonal than sexual
Tibayrenc, M; Ayala, FJ (Parasitology Today, 1987-06)The ancient guestion of trypanosome sexuality has recently been reactivated in view of important observations in the African species Trypanosoma brucie, in which Mendelian sexuality has been proposed as o working hypothesis ...
