Bulbophyllum apertum flower (Orchidaceae) releases raspberry ketone (RK) in its fragrance, which attracts males of several fruit fly species belonging to the genus Bactrocera. Besides RK as a major component, the flower contains smaller amounts of 4-(4-hydroxylphenyl)-2-butanol, plus two minor volatile components, veratryl alcohol and vanillyl alcohol. Within the flower, the lip (labellum) had the highest concentration of RK with much smaller quantities present in petals; other flower parts had… 
Zingerone in the Flower of Passiflora maliformis Attracts an Australian Fruit Fly, Bactrocera jarvisi (Tryon)
TLDR
The attraction of male B. jarvisi to P. maliformis flowers is most readily explained by the presence of zingerone in these flowers, although compositions varied markedly amongst the flower parts.
Floral Phenylpropanoid Cocktail and Architecture of Bulbophyllum vinaceum Orchid in Attracting Fruit Flies for Pollination
TLDR
In this unique mutualistic association, both species receive direct reproductive benefits—the flower’s pollinarium is transported for cross pollination, and the fly is offered a bouquet of phenylpropanoids (synomone) that it consumes, converts, and/or sequesters as sex pheromonal components, thus enhancing sexual attraction and mating success.
Floral fragrances in two closely related fruit fly orchids, Bulbophyllum hortorum and B. macranthoides (Orchidaceae): assortments of phenylbutanoids to attract tephritid fruit fly males
TLDR
Chemical profiles of two closely related Bulbophyllum orchids are examined to see a relation between chemical profiles and phylogenetic classification in the related species, and molecular phylogenetic relationships among phenylpropanoid- or phenylbutanoid-producing or chids are analyzed.
Sapromyiophily in the native orchid, Bulbophyllum variegatum, on Réunion (Mascarene Archipelago, Indian Ocean)
TLDR
Investigation of the floral morphology, breeding system, pollinator diversity, floral scent profile and fruiting success of about 30 individuals in three natural populations during two consecutive flowering seasons showed that Bulbophyllum variegatum is self-compatible, but requires pollinator service to achieve reproduction.
Effects of methyl eugenol and raspberry ketone/cue lure on the sexual behavior of Bactrocera species (Diptera: Tephritidae)
TLDR
Research on the potential role of ME and RK/CL—as pheromone precursors or components—in the sexual communication of Bactrocera species is summarized and potentially productive avenues of future research are discussed.
Relative response of male Bactrocera frauenfeldi (Diptera: Tephritidae) to phenylbutanoid phytochemicals: implications for fruit fly control and plant–insect interactions
TLDR
This study identified the most attractive lure, which is important for monitoring and management of B. frauenfeldi; and revealed the ecological significance of these phytochemical lures in plant-fruit fly co-evolution.
F LORAL SCENT AND POLLINATORS OF THE HOLOPARASITE P ILOSTYLES THURBERI ( A PODANTHACEAE )
Floral scent is likely important to the pollination of parasitic plants, despite that it has not been wellstudied. We studied the pollination ecology of the North American stem holoparasite
Raspberry ketone supplements provided to immature male Queensland fruit fly, Bactrocera tryoni (Froggatt), increase the amount of volatiles in rectal glands
TLDR
Unaltered RK was dominant along with these two endogenous compounds in RK-fed males in rectal gland until 30 days of age in both diet groups, and the present study investigated this possibility.

Mutual Reproductive Benefits Between a Wild Orchid, Bulbophyllum patens, and Bactrocera Fruit Flies via a Floral Synomone
TLDR
The solitary flower of Bulbophyllum patens selectively attracts male fruit flies of several Bactrocera species with a specific fragrance in the rain forest of Malaysia via a floral synomone, in which both organisms obtain advantages directly benefiting their reproductive systems.
Floral Synomone of a Wild Orchid, Bulbophyllum cheiri, Lures Bactrocera Fruit Flies for Pollination
TLDR
In this orchid–fruit fly association, both organisms gain direct reproductive benefits: the orchid flower gets pollinated without having to offer nectar, while the fruit fly boosts its pheromone and defense system, as well as its sexual competitiveness by feeding on the ME produced by the flower.

TLDR
Synthetic 1,3-nonanediol, a component of male melon fly sex pheromone produced endogenously, when topically applied onto the thorax of housefly Musca domestica at ca.
Accumulation ofDendrobium superbum (orchidaceae) fragrance in the rectal glands by males of the melon fly,Dacus cucurbitae
TLDR
4-Hydroxyphenyl)-2-butanone was characterized from flowers of the orchid Dendrobium superbum as a specific attractant factor for the male melon fly, Dacus cucurbitae, and sequestered the compound in significant quantities in their rectal glands.
Species diversity and abundance of Dacus (Diptera: Tephritidae) in five ecosystems of Penang, West Malaysia
TLDR
Analysis showed that for each species of Dacus the difference between ecosystems was highly significant, and the highest numbers of males of D. caudatus trapped were from a village, on a vegetable farm for D. cucurbitae , and D. occipitalis was only caught in a forest.
The gynostemium of Bulbophyllum ecornutum (J. J. Smith) J. J. Smith (Orchidaceae)
TLDR
Stages in the development of the gynostemium of Bulbophyllum ecornutum demonstrate that the pollinium stalk is a hamulus in this and in a closely related species, B. gibbolabium.
Chemical ecology of Dacinae fruit flies (Diptera: Tephritidae).
TLDR
This review focuses on current understanding of Dacinae chemical ecology as it relates to evolution, host selection, reproduction, adult behavior, and control of these fruit flies.
The Orchids: Natural History and Classification
TLDR
This lively examination of the structure, classification, evolution, and ecology of the Orchidaceae will appeal to anyone with an eye for beauty or a bent for natural history, and will provide professional biologists and amateur orchidists alike with a deeper understanding of this, the largest flowering family in the plant kingdom.
Cue lure and the mating behavior of male melon flies (Diptera: Tephritidae).
TLDR
Investigation of the mating behavior of male Bactrocera cucurbitae suggests that exposure of sterile males to cue lure might improve the effectiveness of sterile insect release as well as enable simultaneous control programs of sterile Insect release and male annihilation.
