Evaluation of trap color and CO₂ source of Esperanza window traps for collecting <i>Simulium ochraceum</i> s.l. females.

<p>All traps were co-baited with the BG-lure. Data are from 20-min collecting periods in the community of Las Golondrinas, Chiapas. Letters denote significant differences among traps for the percentage of total flies captured each day. Panel A: Esperanza window traps baited with commercial CO₂. Panel B: Esperanza window traps baited with yeast-generated CO₂.</p

Comparison of traps for collecting the onchocerciasis vector <i>Simulium ochraceum</i> s.l. in the community of Las Golondrinas, Chiapas in Mexico.

<p>Traps were operated simultaneously, with positions rotated daily. Panel A: Mean females captured at each sampling time (1100 h, 1400 h, 1700h) over six days. Panel B: Percentage of total females captured each day by traps over six days. Letters denote significant differences among traps for the percentage of total flies captured each day.</p

Comparison of Esperanza window traps and vector collectors for collecting <i>Simulium ochraceum</i> s.l. females.

<p>Traps were baited with CO₂ (yeast-generated) and BG-lure. Data are from 60-min collecting periods, during two trials at plots in the community of Las Golondrinas, Chiapas, Mexico. Asterisks denote significant differences among treatments for the percentage of total flies captured each day, as determined by t-test.</p

Comparison of baited and unbaited Esperanza window traps and vector collectors for collecting <i>Simulium ochraceum</i> s.l. females.

<p>Treatments included CO₂ (commercial grade), a shirt worn by a local villager, BG-lure, 1-octen-3-ol, ethanol (control), unbaited trap, and a vector collector team. Data are from 20-min collecting periods, at a site in the community of Las Golondrinas, Chiapas, Mexico, 2012. Letters denote significant differences among treatments for the percentage of total flies captured each day.</p

Traps evaluated for potential in collecting <i>Simulium ochraceum</i> s.l. females in Mexico.

<p>Panel A: vertical Bellec plaque. Panel B: Esperanza window trap (original). Panel C: BG Sentinel. Panel D: clear window trap. Panel E: Esperanza window trap (acrylic/hanging version). Panel F: horizontal Bellec plaque. Panel G: human silhouette trap (latex examination glove for scale).</p
