“…1‐Tridecanol was predominant followed by phytol in the volatiles of Momordica charantia L. (bitter gourd) plants, and geraniol, 1‐tridecanol, and phytol attracted Epilachna dodecastigma Wiedemann beetles (Sarkar et al., ). The major VOCs emitted by fruit and vines of bitter gourd have been found to contain myrtenol, ( Z )‐3‐hexenol, benzyl alcohol, 1‐penten‐3‐ol, ( Z )‐2‐pentenol, ( E )‐2‐hexenal, and cis ‐sabinol, and these volatiles elicited attraction of the fly Dacus cucurbitae (Coquillett) (Binder et al., ). Linalool, 2‐aminobenzaldehyde, 1H‐indole and methyl anthranilate were the most abundant compounds accounting for 95% of the volatiles of M. charantia flowers (Fernando & Grün, ), but those compounds were not detected in volatiles of M. charantia plants.…”

Aulacophora foveicollis Lucas (Coleoptera: Chrysomelidae) is an important phytophagous pest of two cucurbitaceous plants, Momordica cochinchinensis Spreng and Solena amplexicaulis (Lam.) Gandhi. The volatile organic compound profiles from flowers of M. cochinchinensis and S. amplexicaulis were identified and quantified by gas chromatography-mass spectrometry (GC-MS) and GC-flame ionization detector (FID) analyses. Twenty nine and 28 compounds were identified in volatiles of M. cochinchinensis and S. amplexicaulis flowers, respectively. Methyl jasmonate and 3-octanol were the predominant volatiles of M. cochinchinensis flowers, whereas 1-octadecanol and 1-hexanol were most found in the headspace of S. amplexicaulis flowers. Aulacophora foveicollis were more attracted by the flower volatiles of M. cochinchinensis than by those of S. amplexicaulis in a glass Y-tube olfactometer. A mixture of 1-heptanol, linalool oxide, 1-octanol, and nonanal in the proportions present in the headspace of both flower types elicited attraction in the insect. From 25 cm distance, A. foveicollis displayed a preference for artificial flowers of 6.5 cm diameter of S. amplexicaulis flower colour (white) over M. cochinchinensis flower colour (white-yellow). Finally, a synthetic blend (0.43 lg 1-heptanol + 1.44 lg linalool oxide + 0.14 lg 1-octanol + 1.77 lg nonanal dissolved in 25 ll methylene chloride) attracted more beetles when applied in a white artificial flower than when applied in a white-yellow artificial flower from 40 cm distance. This finding may be helpful in the development of traps for pest management strategies.

“…One of these, (E)-6-nonenyl acetate, attracts female melon flies (Jacobson et al 1971) as well as stimulates oviposition (Keiser et al 1973). Other compounds, including (Z)-3-hexen-1-ol and E2-6:al, are prominent in extracts of bittermelon, Momordica charantia L., and attract B. cucurbitae (Binder et al 1989). …”

Cucumber Volatile Blend Attractive to Female Melon Fly, Bactrocera cucurbitae (Coquillett)

The melon fly, Bactrocera cucurbitae (Coquillett), is a serious crop pest throughout the Asia Pacific sub-continent and Southeast Asia, causing damage to tree fruits, cucurbits, and related crops. Attractants for female melon flies are of particular interest as they could be used in control tactics to reduce pest levels. Previous work has shown that freshly sliced cucumbers are attractive to female melon flies, but the compounds responsible for this attraction were not identified. The objective of the present study was to create a synthetic lure for female B. cucurbitae based on its close association with Cucurbitaceae. Coupled gas chromatography-electroantennogram detection (GC-EAD) analysis of fresh and aged puréed cucumbers identified 31 compounds that were detected by females. Compounds that elicited EAD responses initially were screened as single components in glass McPhail traps in outdoor rotating olfactometer experiments. Four criteria were used to select compounds for testing in blends: a) strength of EAD response elicited; b) amount of compound present; c) relative attractiveness of a single compound; and d) compound novelty to Cucurbitaceae. Several synthetic blends attracted significant numbers of females in outdoor rotating olfactometer experiments; a nine-component blend (lure #7) was the most attractive. Field captures of female B. cucurbitae in traps baited with lure #7 were twice those in traps baited with Solulys protein bait. Besides having a female-biased attraction, this lure may have several advantages over protein baits: it can be used with a dry trap, is long lasting, and it captured low numbers of non-target species. Possible applications of this lure include trapping (for detection and/or monitoring/delimitation) and control/eradication (e.g., mass trapping, attract-and-kill, or as an attractant for existing protein insecticide bait sprays such as GF-120).

“…Numerous aldehydes have been reported in other Cucurbitaceae such as bittermelon (Momoridica charantia L.), cucumber (Cucumis sativus L.), and watermelon (Citrullus lanatus Thunb.) (Binder et al, 1989;Fleming et al, 1968;Yajima et al, 1985); and (Z)-3-hexenal and (E)-2-hexenal were attributed to the "green notes" in C. melo (Schieberle et al, 1990). In year-1, four scientists observed that only immature cantaloupe (13 and 20 DAA) smelled and tasted like cucumber.…”

A likely reason why consumers are not repeat buyers of many fresh-cut fruit is inconsistent or unsatisfactory flavor and/or textural quality. Research toward understanding mechanisms responsible for generation, and/or loss of flavor compounds in fresh-cut fruit is limited. Solid phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) were utilized to study flavor volatile profiles in anthesis-tagged cantaloupe (Cucumis melo L. var. reticulatus Naud. cv. Sol Real) during growth, development, and for fresh-cuts prepared from fruit with five distinctly different harvest maturities. One-quarter-slip fruit had a clearly green, well-attached peduncle; 1/2-slip fruit had a distinct abscission detectable at the peduncle, 3/4-slip fruit were approaching commercial harvest, full-slip (FS) fruit are or will cleanly separate from the vine with light pressure; and over-ripeness (OR) was precisely categorized as 2 days past FS. Recovery of total volatiles displayed a linear response and most volatile classes (except aldehydes) generally followed a trend upon processing where FS > 3/4-slip > 1/2-slip > 1/4-slip. On day 0, only 70.0%, 37.7%, and 20.5% total volatiles were recovered in 3/4-slip, 1/2-slip, and 1/4-slip fruit, compared to FS fruit. During fresh-cut storage, percent total esters followed an increasing linear trend that was maturity-dependent. Percent total aromatics and percent aldehydes followed a linear trend that was maturity-dependent whereby 1/4-slip > 1/2-slip > 3/4-slip > FS. During storage, the relative percentage of acetates decreased, and displayed a maturity-dependent curvilinear trend. The magnitude of the slope decreased with maturity, indicating that the effect of storage time decreased as maturity increased. In FS, 3/4-slip, 1/2-slip, and 1/4-slip cubes, acetates comprised 66.9% of all compounds recovered on day 0 yet, only 26.1% to 44.2%, and 21.3% to 32.6% remained on days 9 and 14, respectively. For all maturities, a curvilinear increase in relative percentage of nonacetate esters was observed during storage. There was a uniform change in the ester balance (nonacetate ester:acetate ratio) during fresh-cut storage, which was independent of initial processing maturity. The overall ester ratio changed roughly 2-fold after just 2 days in optimum storage, and after 5 days it increased more than 3-fold. The shift in endogenous ester compounds could be partially responsible for the apparent loss of characteristic flavor in fresh-cut cantaloupe through long-term storage.
