Abstract

The blacklegged tick (Ixodes scapularis Say) vectors several bacterial, protozoan, and viral human pathogens. The known distribution, abundance, and phenology of I. scapularis within its estimated range are incomplete. This gap in knowledge is problematic because these factors are important for determining acarological risk of exposure to infected ticks. Consequently, enhanced surveillance of I. scapularis is being promoted and supported in the United States. Although the most common method for collecting I. scapularis is by dragging a sturdy cloth along the ground, there are no published empirical data showing which drag fabric is most effective. We used a randomized block design to directly compare the relative efficiencies of canvas, corduroy, and flannel drags for the collection of larval, nymphal, and adult I. scapularis. Overall, flannel was the most effective fabric and canvas was the least effective. Significantly more adults were collected on flannel than on canvas or corduroy, and the same number of nymphs was collected on flannel and corduroy. Significantly more larvae were collected on flannel than on canvas, but one-third of larvae could not be removed from the former fabric by lint-rolling, and handpicking was difficult. Our findings support the use of flannel drags to maximize sampling effort for collection of I. scapularis, especially adults to determine the presence of ticks and tick-borne pathogens when density and infection prevalence are low, with the caveat that detection and removal of larvae are time-consuming.
