A Bioassay for Host-Seeking Responses of Tick Nymphs (Ixodidae)1

Open publisher page 2 citations

Abstract

A choice tube bioassay for host-seeking behavior was developed for ticks (Ixodidae) using nymphs of Dermacentor variabilis (Say), Amblyomma ameri canum (Linnaeus) and Rhipicephalus sanguineus (Latreille). A methanol extract of dog hair presented in the choice tubes significantly attracted the ticks, especially at 37?C, the host body temperature. Nymphs younger than 15 days responded indifferently to odors; beyond that age, responses became more pronounced. The compound N, iV-diethyl-m-toluamide elicited highly reproducible responses from the ticks.
