Introduction

INTRODUCTION

  • A preliminary survey TYAD, Pennsylvania was conducted from 7-10 October, 2003 to identify the distribution of Ixodes scapularis, chiggers and acarine diversity.

  • The distribution of acarines was identified and predictive models based on soil type were developed using GIS.


Materials and methods

MATERIALS AND METHODS

  • Two methods of collecting arthropods were used

    • Thirty-six 100m drags - 1m2 cloth

      • drags were conducted on 12 of 17 soil types representing 91% of the soil area

    • The Biter Fighter™ uses chemical attractants and a glue board

      • placed on 3 soil types

  • Menhinick’s Index was used for measurement of acarine abundance


Results

RESULTS

  • 40 individuals from 8 groups

    • Collohmania spp., Ixodidae, Johnstonianidae, Oribatululoidea, Tetranychidae, Trombellidae, Trombiculidae, Trombidiidae

  • Chippewa and Norwich extremely stony soils; 0-8% slopes (CNB) had a significantly higher mean MI (mean=1.3, sd=0.19) than the MI of Oquaga-Lackawanna channery loams; 0-8% slopes (OXB) (mean=0.50, sd=0.71).

  • The mean MI of Morris extremely stony silt loam; 0-8% slopes (MOB) (mean=1.0, sd=0.26) was not significantly different than either CNB or OXB).


Results cont

Results (cont)

  • The lowest diversity of mites was found in Eastern white pine, red pine, European larch, Norway spruce with channery loam soil with moderate slopes.

  • Chiggers (Trombiculidae) were found CNB and MOB soil types.

  • One male and one female I. scapularis were collected on consecutive days from one site by drag on CNB.
