Abstract
The spray of the Asian whipscorpion, Typopeltis stimpsoni (Wood, 1862), was investigated chemically using a gas chromatograph-mass spectrometer. The spray mainly consisted of acetic acid, caprylic acid and water. No other fatty acids and volatile materials could be detected in the spray. Contents of the major components were determined by mass-fragmentography and the following result was obtained : acetic acid, 78.3% (v/v); caprylic acid, 5.8% (v/v); water, 15.9% (v/v). These values are quite similar to those of the American species, Mastigoproctus giganteus (Lucas, 1835) and those of the other Asian whipscorpion, T. crucifer Pocock, 1894.
