DISTRIBUTION OF TRIATOMIDS FOUND IN HOMES OF GENERAL TERAN MUNICIPALITY (NUEVO-LEON, MEXICO)

The purpose of this work was to determine the species of triatomids present in ten villages of General Teran, N.L., Mexico as well as their entomological indexes, monthly distributions, sex ratios and relationships with human dwellings. Captured species were Triatoma gerstaeckeri (192) and T. lecticularia (9). Triatoma gerstaeckeri was found in ten villages (IDD=80) and 15 houses (II=24); T. lecticularia on the other hand was found in only four villages (IDD=40) and five houses (II=8.08). A positive reaction to the presence of Trypanosoma cruzi was similar with both species (IIN=28 and 33 respectively). The greatest number of individuals were trapped during the month of June (90 T. gerstaeckeri and two T. lecticularia). Of 192 T. gerstaeckeri trapped during this time, 124 (64.58%) were females and 68 (35.42%) were males; only 8 females (88.89%) and 1 male (11.11%) of T. lecticularia were captured. Both species are considered to be peridomiciliar triatomids attempting to adapt to human dwellings because most of the T. gerstaeckeri (181/97.27%) and the T. lecticularia (6/66.67%) were captured around human dwellings.
