| genetic and cytogenetic analysis of the american cherry fruit fly, rhagoletis cingulata (diptera: tephritidae). | the american eastern cherry fruit fly, rhagoletis cingulata, a pest of cherries in the western hemisphere, invaded europe in 1983, and since then dispersed to several european countries. information on the genetics and cytogenetics of this pest is very scarce. the mitotic karyotype and detailed photographic maps of the salivary gland polytene chromosomes of r. cingulata are presented here. the mitotic metaphase complement consists of six pairs of chromosomes with the sex chromosomes being very s ... | 2011 | 22447527 |
| wolbachia in parasitoids attacking native european and introduced eastern cherry fruit flies in europe. | the eastern cherry fruit fly, rhagoletis cingulata loew (diptera: tephritidae), is an economically important pest of cherries in north america. in 1983 it was first reported in europe where it shares its ecological niche with the native european cherry fruit fly, rhagoletis cerasi l. (diptera: tephritidae). their coexistence in europe led to the recent horizontal transmission of the wolbachia strain wcer1 from r. cerasi to r. cingulata horizontal wolbachia transmission is mediated by either shar ... | 2016 | 28028089 |
| evidence for a recent horizontal transmission and spatial spread of wolbachia from endemic rhagoletis cerasi (diptera: tephritidae) to invasive rhagoletis cingulata in europe. | the widespread occurrence of wolbachia in arthropods and nematodes suggests that this intracellular, maternally inherited endosymbiont has the ability to cross species boundaries. however, direct evidence for such a horizontal transmission of wolbachia in nature is scarce. here, we compare the well-characterized wolbachia infection of the european cherry fruit fly, rhagoletis cerasi, with that of the north american eastern cherry fruit fly, rhagoletis cingulata, recently introduced to europe. mo ... | 2013 | 23844658 |
| reproductive maturity of cherry fruit fly (diptera: tephritidae) in managed and natural habitats. | we studied the timing of reproductive maturity of cherry fruit fly, rhagoletis cingulata (loew), a key pest of sweet and tart cherries in the eastern united states. to determine when cherry fruit fly females become reproductively mature in managed and natural habitats, we deployed traps in sweet and tart cherry orchards and nearby stands of the ancestral host tree, black cherry. flies were removed from the traps and females were dissected to determine the presence of fully developed eggs. we fou ... | 2009 | 19689872 |
| habitat-specific flight period in the cherry fruit fly rhagoletis cingulata (loew) (diptera: tephritidae). | flight periods of the cherry fruit fly, rhagoletis cingulata (loew), were compared in the major sweet and tart cherry-growing regions of michigan, among neglected orchards, managed orchards, and natural areas containing the ancestral host, black cherry. traps were deployed from early june to late september 2005 and 2006. captures indicated that cherry fruit fly has an early flight (june-july) in neglected orchards, a mid-season flight peaking immediately after harvest (june-august) in managed or ... | 2007 | 18284761 |
| genetic evidence for the introduction of rhagoletis pomonella (diptera: tephritidae) into the northwestern united states. | the apple maggot fly, rhagoletis pomonella walsh (diptera: tephritidae), is a serious quarantine pest in the apple-growing regions of central washington and oregon. the fly is believed to have been introduced into the pacific northwest via the transport of larval-infested apples near portland, oregon, within the last 40 yr. however, r. pomonella also attacks native black hawthorn, crataegus douglasii lindley (rosales: rosaceae), and introduced ornamental hawthorn, crataegus monogyna jacquin, in ... | 2017 | 29029209 |
| the effect of winter length on duration of dormancy and survival of specialized herbivorous rhagoletis fruit flies from high elevation environments with acyclic climatic variability. | dormancy can be defined as a state of suppressed development allowing insects to cope with adverse conditions and plant phenology. among specialized herbivorous insects exploiting seasonal resources, diapause frequently evolves as a strategy to adjust to predictable plant seasonal cycles. to cope with acyclic and unpredictable climatic events, it has been found for some insects that a proportion of the population undergoes prolonged dormancy. we compared the response of three species in the rhag ... | 2017 | 28925346 |
| behavioral responses of rhagoletis cingulata (diptera: tephritidae) to gf-120 insecticidal bait enhanced with ammonium acetate. | gf-120 is a baited formulation of the insecticide spinosad containing 1% ammonium acetate, developed for control of economically important fruit flies. the response of feral cherry fruit flies, rhagoletis cingulata loew, to gf-120 augmented with 0, 5, or 10% ammonium acetate was evaluated under orchard conditions. significantly more flies were observed within 30 cm of bait droplets with 10% ammonium acetate added compared with standard bait or to a water control. these fly visits to gf-120 enhan ... | 2006 | 16937687 |
