Over 200 beetle- and food-produced volatiles were collected from cultures of the saw-toothed grain beetle Oryzaephilus surinamensis (L.) on oats. It proved possible to develop the electroantennogram recording technique for these beetles. Three beetle-produced macrolide lactones were identified as (Z,Z)-3,6-dodecadien-11-olide, (Z,Z)-3,6-dodecadienolide, and (Z,Z)-5,8-tetradecadien-13-olide in an average ratio of 4.4:1:2. These have been reported as components of the aggregation pheromone from a different population of this species, although the ratio of the components produced was different. Three food volatiles with EAG activity were also identified: 1-octen-3-ol, 3-octanone, and nonanal.
