Acetylcholinesterase in developing embryos of Hyalomma rufipes Koch, 1844 (Ixodoidea: Ixodidae)

Abstract

Acetylcholinesterase (AChE) is demonstrated, apparently for the first time, in developing embryos of the tick Hyalomma rufipes. The enzyme was detected in the neuropile of the oesophageal ganglia and in the nerve endings of the appendages; it was absent from the neurons and neurolemma of the nerve ganglia.
