Volatile compounds of some blueberries cultivars infested with fruit fly Ceratitis capitata

Abstract

It is important to understand the fruit insect interaction mechanism to developing strategies to control the pests. The Mediterranean fruit fly Ceratitis capitata (Medfly) infested some blueberries Vaccinium spp. cultivars, and their volatile compounds composition of infested fruit of those cultivars has been studied. Head space solid-phase microextraction extractiongas chromatography (SPME-GC/MS) has been used to detect volatiles on these cultivars. First Blush 4514 and Brigitta 1403 Australian cultivars used in this experiment. A total of 119 compounds find form these cultivars. There are a major different volatiles and their structure from infested fruits. HS-SPME released complex volatiles including (butanoic acid-3 methyl-, methy ester, methyl isovalerate, Butanoic acid-3 methyl-, isobutyl acetate, ethanone,2,2-dihydroxy-phenyl ) from First blush and Styrene, and 6-Methyl 1-2,3-dihydro-1,4-oxathine, methyl isovalerate, butanoic acid-3 methyl-, methy ester, ethyl isobutenoate from Brigitta cultivar.
