Solid-phase microextraction (SPME) and gas chromatography coupled with electroantennographic detection (GC-EAD) were used to identify a new blend of volatiles from apples as the key attractants for the apple maggot fly, Rhagoletis pomonella (Walsh). The new five-component blend contains butyl butanoate (10%), propyl hexanoate (4%), butyl hexanoate (37%), hexyl butanoate (44%), and pentyl hexanoate (5%) compared with a previously reported seven-component mix of hexyl acetate (35%), (E)-2-hexen-1… 

Identification of Host Fruit Volatiles from Hawthorn (Crataegus spp.) Attractive to Hawthorn-Origin Rhagoletis pomonella Flies

Solid-phase microextraction (SPME) and gas chromatography coupled with electroantennographic detection (GC-EAD) were used to identify volatile compounds from hawthorn fruit (Crataegus spp.) acting as

Attraction of Apple Maggot Flies (Diptera: Tephritidae) to Synthetic Fruit Volatile Compounds and Food Attractants in Michigan Apple Orchards

It is provided further evidence that baiting red-sticky sphere traps with the volatile blend without ammonium bait additives creates a highly effective and selective device for capturing apple maggot flies.

Identification and Field Evaluation of Grape Shoot Volatiles Attractive to Female Grape Berry Moth (Paralobesia viteana)

Solid-phase microextraction and gas chromatography coupled with electroantennographic detection were used to identify volatile compounds from shoots of riverbank grape that attract the female grape berry moth and found that both the 11- component blend and a seven-component blend elicited equivalent levels of upwind flight as freshly cut grape shoots.

Identification of Host Fruit Volatiles from Flowering Dogwood (Cornus florida) Attractive to Dogwood-Origin Rhagoletis pomonella Flies

This study adds to previous ones showing that populations of Rhagoletispomonella flies infesting apple, hawthorn, and flowering dogwood fruit are attracted to unique mixtures of fruit volatiles, supporting the hypothesis that host fruit odors could be key traits in sympatric host shifts and establishing host fidelity within members of the Rhago letispom onella species complex.

Identification of Host Fruit Volatiles from Snowberry (Symphoricarpos albus), Attractive to Rhagoletis zephyria Flies from the Western United States

The hypothesis that differences among flies in their behavioral responses to host fruit odors represent key adaptations involved in sympatric host plant shifts is supported, contributing to host specific mating and generating prezygotic reproductive isolation among members of the R. pomonella sibling species complex.

Identification of a New Blend of Host Fruit Volatiles from Red Downy Hawthorn, Crataegus mollis, Attractive to Rhagoletis pomonella Flies from the Northeastern United States

The hypothesis that in addition to providing specificity to the odor blends of the northern and southern hawthorn populations, the presence of the significant amounts of esters identified from the headspace of domesticated apple might have provided a source of standing variation that could help explain the shift in host preference by C. mollis-infesting flies to introduced apple in the mid-1800’s is supported.

Electrophysiological and behavioral identification of a volatile blend involved in host location of female strawberry sap beetle, Stelidota geminata

The data indicate that the combination of the ethyl acetate with some or all of the remaining 15 compounds is necessary for this ester blend to be attractive to female SSB, which will be useful for developing new management options for SSB.

Electroantennogram responses of an invasive species fall webworm (Hyphantria cunea) to host volatile compounds

A maximum dosage level of 1000 μg was tested and found to elicit significantly higher activity from male moths compared with lower concentrations, and a positive correlation was found between the fall webworm and the tested compounds.

A Novel Attractant for Anastrepha ludens (Diptera: Tephritidae) from a Concord Grape Product

It is concluded that propylene glycol, acetic acid, methyl anthranilate, water, and at least one or as many as all three of the methyl-branched esters are essential for complete attractiveness.

A New Blend of White Sapote Fruit Volatiles as Potential Attractant to Anastrepha ludens (Diptera: Tephritidae)

Using standard chemical ecology techniques, potential attractants from wild sapote fruit for monitoring and management of A. ludens population were found and antennae of both sexes responded to eight compounds.



Identification of apple volatiles attractive to the apple maggot,Rhagoletis pomonella

Apple volatiles from whole Red Delicious and Red Astrachan apples were found to be attractive to sexually mature apple maggot flies,Rhagoletis pomonella (Walsh), in wind tunnel bioassays and elicited similar behavioral and EAG responses.

Solid phase microextraction for quantitative headspace sampling of apple volatiles.

While SPME is ideal for rapid, qualitative determination of apple headspace volatile, the slower equilibration of higher MW volatiles limits its use for quantification in more complex systems.

Essential Amino Acid Methyl Esters: Major Sex Pheromone Components of the Cranberry White Grub, Phyllophaga anxia (Coleoptera: Scarabaeidae)

GC-EAD analysis indicates that L-valine and L-isoleucine methyl esters are the major sex pheromone components released by females of the cranberry white grub, Phyllophaga anxia (LeConte).

Headspace Analysis in Chemical Ecology: Effects of Different Sampling Methods on Ratios of Volatile Compounds Present in Headspace Samples

The effects that different headspace sampling methods have on the analysis of the ratios of compounds present in the headspace of a synthetic mixture and a biological sample were evaluated using the

Specificity of olfactory responses in the tephritid fruit fly, Rhagoletis pomonella

The results suggest that R. pomonella is adapted to perception of a compound that is typical of its hosts, and this ester, butyl hexanoate, appears in significant concentrations in the headspace of host fruit.

Field Tests of Synthetic Apple Volatiles as Apple Maggot (Diptera: Tephritidae) Attractants

In field tests in abandoned and commercial orchards in New York, sticky-red spheres baited with a blend of synthetic apple volatiles captured significantly more male and female apple maggot flies,

Variation in host fruit volatiles attractive to apple maggot fly,Rhagoletis pomonella

Within the approximate range of the GLC fraction known to elicit behavioral activity in the apple maggot fly,Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), 52 esters were identified.

Calibration of a commercial solid-phase microextraction device for measuring headspace concentrations of organic volatiles.

The calibration factors (amount absorbed by the fiber divided by headspace concentration) were determined for 71 compounds using SPME fibers with a 100 μm poly(dimethylsiloxane) coating, which supported the accuracy of the measured calibration factors.

Distance of response to host tree models by female apple maggot flies,Rhagoletis pomonella (Walsh) (Diptera: Tephritidae): Interaction of visual and olfactory stimuli

These results suggest that female apple maggot flies did not detect green 1-m2 models with odor 4.5m away or models without odor 2.5 m or more away, and responded to white models with and without odor to a much lesser extent, both in terms of response distance and flight to and alightment upon models.

Host odor and visual stimulus interaction during intratree host finding behavior ofRhagoletis pomonella flies

It is indicated that after arrival on a host tree (point source), flies discover individual apparent and abundant host fruit on the basis of vision, and odor appears to interact with vision during the fruit-finding process.
