| gonotrophic status, sperm presence and sugar feeding patterns in southwestern quebec tabanid (diptera) populations. | parity, stage of follicular development, sperm and fructose presence were determined for 6 tabanid species from southwestern quebec during 2 consecutive years. females were collected in canopy traps baited with or without carbon dioxide. based on the presence or absence of host-seeking nulliparous flies (nullipars), hybomitra epistates, h. nitidifrons nuda, h. sodalis, tabanus lineola and t. similis were classified as being anautogenous. hybomitra frontalis was classified as autogenous for its f ... | 1989 | 2511274 |
| ticks and biting insects infected with the etiologic agent of lyme disease, borrelia burgdorferi. | members of 18 species of ticks, mosquitoes, horse flies, and deer flies were collected in southeastern connecticut and tested by indirect fluorescent-antibody staining methods for borrelia burgdorferi, the etiologic agent of lyme disease. an infection rate of 36.2% (116 tested), recorded for immature ixodes dammini, exceeded positivity values for all other arthropod species. prevalence of infection for hematophagous insects ranged from 2.9% of 105 hybomitra lasiophthalma to 14.3% of seven hybomi ... | 1988 | 3170711 |
| synergism between ammonia and phenols for hybomitra tabanids in northern and temperate canada. | baits for tabanids (diptera: tabanidae) were tested in the northwest territories (60 °n) and ontario (45 °n) using nzi traps. tests targeted ammonia, phenols/cow urine and octenol. about 200 000 tabanids were captured in 15 experiments with a maximum capture of 4182 in one trap in 1 day. in the northwest territories, phenols, urine and octenol were effective single baits for only some species. at both locations, adding ammonia to an unbaited or an octenol-baited trap had no effect on catches. by ... | 2011 | 22150639 |
