- We conducted two experiments to determine the best CDC-trap configuration for catching male and female Phlebotomus papatasi. First, visual features were evaluated. Standard CDC traps were modified to have black or white catch bags, black or white lids, or no lids and these were tried in different combinations. Significantly more male sand flies were caught by darker traps; significantly more females were captured by traps with either all black or a combination of black and white features. Attraction may be due to dark color or contrast in colors. CDC traps with suction and the following features were also evaluated: no light; incandescent light; ultraviolet (UV) light; combination of black color, heat and moisture; CO2 alone, or a combination of black color, heat, moisture, and CO2 simultaneously, all in upright and inverted positions, with the opening for insect entry always 50 cm above the ground. Significantly more females than males were caught by all traps (standard and inverted) except the control traps with suction only. Traps with CO2 caught more sand flies than traps without CO2. Traps with black color, heat and moisture captured significantly more sand flies than the control traps, but with the addition of CO2, these traps catch significantly more sand flies than the other traps evaluated. Inverting traps increased the catch for like traps by about two times.
