Abstract

 
Mites are a major cause of qualitative and quantitative losses to several stored food and feed products. The present work aimed to study the effect of infection by Caloglyphus berlesei on chemical organic volatile compound of some stored products. Volatile compounds were evaluated for soybean, wheat, maize and fishmeal before and after infestation with mites after three months by GC/MS. Soybean infected by Caloglyphus berlesei caused to presence of different six compounds. Also,wheat infected caused to presence of different ten compounds. There were fifty compounds evaluated from stored maize by GC/MS. Maize infected presence of sixty six compounds, twenty of them were appeared different. There were four compounds present in stored maize uninfected but not detected in infected stored maize. Fishmeal infected by Caloglyphus berlesei after three months caused to presence of forty six compounds, twenty five of them were appeared different. There were six compounds present in stored fishmeal uninfected but not appeared in infected stored fishmeal. Volatile compounds in stored products (soybean, wheat, maize and fishmeal) appeared that 1- aminododcane and 10-Undecenal were related with Caloglyphus berlesei in all stored products under investigation.
