The effects of human volatiles produced by skin microbiota on Forcipomyia (Lasiohelea) taiwana host preference.

ABSTRACT:

Background

Midges are widely distributed globally. They can transmit numerous serious diseases when biting hosts. It is crucial for developing more effective midge monitoring and control methods to better understand how host volatiles attract and repel these blood-sucking insects.

Results

In this work, volatile substances from human skin were detected by means of gas chromatography-mass spectrometry (GC-MS). A total of 25 compounds in relatively high contents were identified from the gauzes adsorbing volatiles of eight volunteers, including ketones, aldehydes, alcohols and acids. Nonanal, 6-methyl-5-hepten-2-one and decyl aldehyde were all present in the skin volatiles of the volunteers, at relatively stable and high levels. Our results showed that 0.001% geranylacetone exhi
