Effect of 1-octen-3-ol, the Ruminant Kairomone on Ixodid Tick Larvae

Abstract
In vitro evaluations were made to evaluate the effi cacy of 1-octen-3-ol on fi ve ixodid larval stages using Petridish bioassay. The species of the ruminant ticks which are common in Indian sub continent including Rhipicephalus (Boophilus) microplus, Haemaphysalis bispinosa, Rhipicephalus haemaphysaloides, Hyalomma marginatum and dog tick Rhipicephalus sanguineus were made use in the current study. Amongst the ruminant tick larvae tested with 1-octen-3-ol, maximum attraction of 72 per cent and 71 per cent was recorded for H. marginatum and R. microplus respectively while H. bispinosa and R. haemaphysaloides showed 52 and 50 per cent attraction respectively. 1-octen-3-ol being a compound found characteristically in bovine odour failed to evoke any response (questing / attraction) in the brown dog tick.
