Comparison of different trapping methods used in the comparative studies using centers for disease control light traps. Average number of female mosquitoes caught per trap per night. The alphabetical symbols, a and b are used to represent differences as determined by unianova test. Trapping efficiencies for the different trapping methods in collecting a certain species are not significantly different (P = 0.05), if the bars representing a particular species in each trap share any of these alphabets. The Y-error bars represent 95% confidence intervals. LC, CDC light trap baited with Limburger cheese; LT, CDC light trap baited with light on; MC, CDC light trap baited with milk cream; NB, CDC light trap NOT baited.
