| effects of habitat type and drying on ascogregarina barretti (eugregarinida: lecudinidae) infection in aedes triseritatus (diptera: culicidae). | the intensity and prevalence of parasitism by ascogregarina barretti (vavra) in aedes triseriatus (say) did not differ between tires and tree holes in field samples taken in september 1996. there was significant variation in the intensity of parasitism among containers that was not significantly correlated with the ph, conductivity, or temperature of the container water. in an experiment manipulating habitat drying, treatments had a significant effect on a. barretti infection of ae. triseriatus, ... | 0 | 11126556 |
| a parasite's modification of host behavior reduces predation on its host. | parasite modification of host behavior is common, and the literature is dominated by demonstrations of enhanced predation on parasitized prey resulting in transmission of parasites to their next host. we present a case in which predation on parasitized prey is reduced. despite theoretical modeling suggesting that this phenomenon should be common, it has been reported in only a few host-parasite-predator systems. using a system of gregarine endosymbionts in host mosquitoes, we designed experiment ... | 2017 | 28261457 |
| differential identification of ascogregarina species (apicomplexa: lecudinidae) in aedes aegypti and aedes albopictus (diptera: culicidae) by polymerase chain reaction. | we report 2 polymerase chain reaction (pcr)-based methods for distinguishing morphologically similar gregarine species based on amplification of variable regions of the internal transcribed spacer region of ribosomal dna. the gregarines we investigated were ascogregarina barretti (vavra), a. culicis (ross), and a. taiwanensis (lien and levine), parasites of the mosquitoes ochlerotatus triseriatus (say), aedes aegypti (linnaeus), and ae. albopictus (skuse), respectively. these 3 important vector ... | 2005 | 16539016 |
| effects of ascogregarina barretti (eugregarinida: lecudinidae) infection on aedes triseriatus (diptera: culicidae) in illinois. | ascogregarina barretti (vavra), a gregarine protozoan parasite, infected 23.6 and 5.0% of aedes triseriatus (say) adults that emerged from pupae collected from an east-central illinois tire dump in 1990 and 1991, respectively. infection significantly reduced the wing length of males and females in both years, but its effect was greatest in 1991. females were approximately 1.7 times as likely to be infected as males. infected pupae were 3.53 and 2.76 times more likely to die than uninfected pupae ... | 1992 | 1460637 |
| effects of ascogregarina barretti (eugregarinida: lecudinidae) infection on emergence success, development time, and size of aedes triseriatus (diptera: culicidae) in microcosms and tires. | | 1987 | 3108509 |
| electrophoretic differences in the isoenzymes of two mosquito gregarines, ascogregarina barretti and a. geniculati. | cross-infection experiments demonstrated that ascogregarina barretti, from aedes triseriatus, completes its life cycle in aedes geniculatus. parasite numbers were comparable to infection with ascogregarina geniculati, making the separation of these parasites by host preference difficult. however, electrophoresis readily distinguished isoenzymes from the two morphologically similar gregarine species. different migration rates were obtained for isocitrate dehydrogenase 1 and 2, lactate dehydrogena ... | 1984 | 6429310 |
