Figure 2. Temporal pattern of adult Triatoma rubida insects collected in metropolitan Tucson, Arizona, USA, May–August, 2006. A) Average minimum daily temperature recorded in 2006 during the period shown (data obtained from www.wrh.noaa.gov/twc/climate/reports.php). B) Percentages of all adults (n = 134), males (n = 52), and females (n = 82) collected during the period, in 5-day intervals (e.g., the percentage of insects collected during May 15–19 is represented on May 17). Information about sex or collection date was not available for 16 adults, so they were not included in this plot.
