Adrenergic ligands that block oviposition in the cattle tick Rhipicephalus microplus affect ovary contraction.

The tyraminergic/octopaminergic system is central for the control of arthropod oviposition. Previous works demonstrated that the pharmacological perturbation of this system inhibits oviposition in the cattle tick Rhipicephalus microplus. In this work, we describe a physiologically active whole-mount preparation of the contractile tick ovary that allows the quantitative videometrical analysis of ovary contraction in response to different compounds.
