Influence of saturation deficit and temperature on Ixodes ricinus tick questing activity in a Lyme borreliosis-endemic area (Switzerland).

摘要: Questing Ixodes ricinus ticks were sampled monthly in a periurban mixed forest at Neuchâtel, Switzerland, 1996, 1997, and 1998. A total of 5530 I. nymphs 1385 adults collected. The emergence questing tick populations spring varied among years relation to the air temperature. variation nymph density was negatively correlated with saturation deficit; there strong decrease numbers late summer as soon deficit increased. also observed between years; high when low during (1997) (1998). During 3-year study period, marked climatic differences highlighted influence temperature on phenology ticks.
