Genetic differentiation between sympatric host races of the apple maggot fly Rhagoletis pomonella
TLDR
The result confirms that hawthorn and apple flies represent partially reproductively isolated 'host races' and is consistent with a sympatric mode of divergence for these flies. Expand
THE GEOGRAPHIC PATTERN OF GENETIC DIFFERENTIATION BETWEEN HOST ASSOCIATED POPULATIONS OF RHAGOLETIS POMONELLA (DIPTERA: TEPHRITIDAE) IN THE EASTERN UNITED STATES AND CANADA
TLDR
The sympatric shift of R. pomonella from its native host hawthorn to introduced domestic apple, which occurred approximately 150 years ago, provides a test of whether host specialization is sufficient to allow populations to differentiate in the absence of geographic barriers to gene flow. Expand
Effects of host switching on gypsy moth (Lymantria dispar (L.)) under field conditions
TLDR
Large differences in gypsy moth growth and survival can occur even among diet sequences composed of favorable host species, and early feeding on red oak followed by later feeding on an aspen is most beneficial to insects in terms of attaining high levels of performance throughout their lives. Expand
Inheritance and Linkage Relationships of Allozymes in the Apple Maggot Fly
We established a genetic basis for six newly studied allozymes in a nondiapausing, laboratory strain of the apple maggot fly, Rhagoletis pomonella, bringing to 18 the number of allozyme loci thatExpand
Intra- and inter-clonal variation in gypsy moth larval performance on bigtooth and trembling aspen
A field study on the effects of interclonal and intraclonal variations of aspens on the performance of gypsy moth, Lymantriadispar (L.), was conducted in Michigan during 1988 and 1989. Study specie...
REGIONAL, LOCAL AND MICROGEOGRAPHIC ALLELE FREQUENCY VARIATION BETWEEN APPLE AND HAWTHORN POPULATIONS OF RHAGOLETIS POMONELLA IN WESTERN MICHIGAN
TLDR
The fine level of genetic subdivision between hawthorn and apple populations of R. pomonella in western Michigan substantiates the existence of host associated polymorphism in the fly and supports a sympatric mode of divergence for the “apple race”. Expand
Are the apple maggot, Rhagoletis pomonella, and blueberry maggot, R. mendax, distinct species? Implications for sympatric speciation
TLDR
Differences in host plant recognition were implicated as important pre‐mating barriers to gene flow between R. pomonella and R. mendax; a result supporting a sympatric mode of divergence for these flies. Expand
Ascertainment of Vital Status Among People With Criminal Justice Involvement Using Department of Corrections Records, the US National Death Index, and Social Security Master Death Files
TLDR
Using data from the NDI and SSDMF may result in differential ascertainment in populations overrepresented in the criminal justice system, such as people who are young, black, or Latino, so it is important to estimate the relative utility of vital status data sources by criminal justice and demographic subgroups. Expand
The geographic pattern of genetic differentiation between host associated populations of Rhagoletis pomonella (Diptera: Tephritidae) in the eastern United States and Canada.
TLDR
The findings suggest that partially reproductively isolated "host races" can evolve in sympatry as a consequence of R. pomonella infesting new host plants and host recognition and host associated developmental traits are discussed as important factors differentiating apple and hawthorn flies.
