Profiling of semiochemicals from three stored product beetles by headspace solid- phase microextraction coupled with gas chromatography–mass spectrometry.

This work focuses on the profiling of semiochemicals (SCS) from
Callosobruchus maculatus, Sitophilus oryzae and Tribolium castaneum
by headspace solid-phase microextraction (HS-SPME) coupled with
gas chromatography–mass spectrometry (GC–MS) technique.
Totally, 6, 9 and 8 volatile compounds (VCS) were detected from
C. maculatus, S. oryzae and T. castaneum, respectively. As a result
of pherobase analysis and preference bioassay, stearic acid (C.
maculatus); nonanal, lauric acid and stearic acid (S. oryzae); stearic
acid (T. castaneum) were identified as new SCS that could be useful
for integrated pest management (IPM) practices.
