“…This compound, along with isobutyl acetate and ethyl hexanoate, were present in headspace VOC samples of fruit-associated yeasts and caused antennal responses in D. melanogaster and D. suzukii (Scheidler et al 2015). Moreover, isoamyl acetate was one of the EAD-active compounds from wild blueberries, attractive to D. suzukii both individually and as part of a blend (Urbaneja-Bernat et al 2021). However, tested in formulated blends for trapping SWD, isoamyl acetate showed no attraction and even a decrease in SWD adult captures (Cha et al 2012).…”

Effect of Drosophila suzukii on Blueberry VOCs: Chemical Cues for a Pupal Parasitoid, Trichopria anastrephae

Biocontrol agents such as parasitic wasps use long-range volatiles and host-associated cues from lower trophic levels to nd their hosts. Although, this chemical landscape may be altered by the invasion of exotic insect species. The spotted-wing drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a highly polyphagous fruit pest native to eastern Asia and recently arrived in South America. The aim of our study was to characterize the effect of SWD attack on the volatile organic compounds (VOCs) of blueberries, a common host fruit, and to correlate these odor changes with the olfactory-mediated behavioral response of resident populations of Trichopria anastrephae parasitoids. Using fruit VOC chemical characterization followed by multivariate analyses of the odor blends of SWD-attacked blueberries, we showed that the development of SWD immature stages inside the fruit generates a different odor pro le than control fruits (physically damaged and free of damage). These differences can be explained by the diversity, frequency and amounts of fruit VOCs. The behavioral response of female parasitic wasps showed that T. anastrephae has an innate attraction to volatile cues from infested host fruits, which may lead to successful location of their insect host. Since resident parasitoids are able locate this novel potential host, biological control programs using local populations may be plausible as a SWD control strategy.

“…Lures used for trapping often have to compete against ripening fruit volatiles in fields and orchards, and less attractive lures and traps that don't effectively capture or kill D. suzukii can result in a spillover effect, leading to an increase in fruit infestation (Hampton et al, 2014;Alnajjar et al, 2017). To determine whether the selected VOC component blends were more attractive than a common fruit host, the four most promising blends from the cage bioassays that were attractive to D. suzukii but not to D. melanogaster, were compared against blueberry fruit with a moderate level of attractiveness to D. suzukii (Abraham et al, 2015;Urbaneja-Bernat et al, 2021). Blueberry was used due to its availability, the space limitations of the trap cups, and the need to avoid cutting fruit due to the emission of induced volatiles.…”

Behavioral Responses of Drosophila suzukii (Diptera: Drosophilidae) to Blends of Synthetic Fruit Volatiles Combined With Isoamyl Acetate and β-Cyclocitral

Baits and lures for trapping and monitoring the invasive vinegar fly Drosophila suzukii Matsumura (Diptera: Drosophilidae) are currently derived from fermentation volatiles. Volatile organic compounds from alternative sources could improve monitoring efforts and optimize capture of gravid females. Through electroantennography and behavioral assays, we evaluated male and female D. suzukii responses to blends of selected synthetic fruit volatiles in combination with the fruit compound isoamyl acetate and the strawberry leaf terpenoid β-cyclocitral. Blends that were attractive to both male and female D. suzukii were then evaluated for attractiveness to a non-target drosophilid, Drosophila melanogaster. A simple 3-component blend of isoamyl acetate, β-cyclocitral and methyl butyrate was attractive to D. suzukii, particularly females, relative to fresh blueberry volatiles. The 3-component blend was not attractive to D. melanogaster. Additional research is needed to determine the effectiveness of this blend to attract D. suzukii under field conditions.

“…In plants, alcohols and ketones are formed from saturated and unsaturated fatty acids, such as linolenic acid by three different pathways: α-oxidation, β-oxidation and the lipoxygenase via [6,43]. Phthalides in plants are derived from 1(3H)isobenzofuranone consisting of one benzene ring bonded with a γ-lactone between carbon atoms [44][45][46][47]. In particular, the 3-butylphthalide is considered to contribute to the fresh aroma of celery [6].…”

In this study, the potential of industrial celery by-products (the stalk and root) serving as sources of aromatics and antioxidants was investigated. A headspace solid phase microextraction–gas chromatography–mass spectrometry (HS-SPME–GC–MS) procedure was optimized to isolate volatile compounds from celery by-products. A Box–Behnken experimental design was proposed to optimize the procedure through a response surface methodology. The optimal extraction conditions were found to be 1.6 g of homogenized fresh by-product at 30 °C for 60 min. Under these conditions, 26 volatile compounds in stalk and root samples were identified, monoterpenes and sesquiterpenes being the main components. The content of limonene and γ-terpinene found in the stalk was significantly higher in comparison with root samples. Total phenolic content and antioxidant activity (ABTS and FRAP) results underlined the celery wastes studied as good sources of free radical scavengers. This work suggests the potential application of these by-products in the food industry and opens new pathways to valorize celery residues, contributing to the circular economy.
