Wilkins, J.P.G., & Soria, S.J. 1996 Identification by gas chromatography -- mass spectrometry (GC-MS) of the compound responsible for the rancid odor of female cysts of Eurhizococcus brasiliensis (Hempel).. Anais da Sociedade Entomologica do Brasil 25(1): 169-170.

Notes: The ground pearl (E. brasiliensis) is a serious pest that damages the root system of grape vines in Brazil. The use of pheromones in insect control is being proposed as an alternative method to reduce populations. This method of control is proposed as a result of field observations of assemblage and courtship of several males attempting to copulate with the same female at the same time. The objective of this work is to determine the chemical nature of the strong goaty odor of virgin females within the cysts, suggesting strong sex pheromonal activity of virgin female to attract males.
