Panstrongylus geniculatus (Latreille, 1811) (Reduviidae: Triatominae) is a hematophagous bug generally associated with the wild cycle of Trypanosoma cruzi Chagas, 1909, the etiological agent of Chagas disease. The incursions of this insect into homes located in urban and peri-urban areas cause alarm in the population and are becoming more and more frequent. As a contribution to the available knowledge on the biology and ecology of P. geniculatus as a species that transmits T. cruzi in this type of environment, the objective was to explore the influence of six environmental variables (altitude, monthly precipitation, relative humidity, average temperature , solar radiation and wind speed) on the distribution of specimens of this species captured in homes of 12 localities of the Metropolitan Area of Caracas (AMC). The parasitological evaluation of the 39 insects examined showed that about 90% of them presented flagellate forms in their feces. The largest number of specimens came from collections in localities of the Miranda state (n = 32), with reports being more common during the months of May and June. Principal Component Analysis (PCA) applied to these data as an exploratory tool concentrates 60% of the variance in the first two principal components and suggests monthly precipitation (mm) and relative humidity (%) as possible environmental variables. explanations of the presence of this species in homes of the AMC.
