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 extraction- gas 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.
Highlights
Ceratitis capitata (Medfly) is an important fly that damage on a huge number of fruits, specially the larvae stage [1]
The main aim of this study is to identify of volatile organic compounds (VOCs) profiles of infested and non-infested blueberries with Mediterranean fruit fly Ceratitis capitata (Medfly) at three times of infestation of larvae
The colony of Medfly was obtained from fruit fly centre (Murdoch University), Australia and the insects were reared in the Laboratory (Murdoch University)
Summary
Ceratitis capitata (Medfly) is an important fly that damage on a huge number of fruits, specially the larvae stage [1]. Using pesticides to control fruit flies were harmful the human and environment [4]. This issue could be more dangerous in fruit production, since many counties rule reduce the use of pesticides. Many researches explain how the infested fruit release different type of volatile organic compounds (VOCs). These chemicals decreases or increases during the ripening period of fruits [11,12,13]. The main aim of this study is to identify of volatile organic compounds (VOCs) profiles of infested and non-infested blueberries with Medfly at three times of infestation of larvae
