1781. DNA content analysis of insect cell lines by flow cytometry Full Text available with Trip Pro

DNA content analysis of insect cell lines by flow cytometry The DNA content of insect cell lines (6 lepidoptera, 1 coleoptera and 1 diptera) was determined by flow cytometry. The DNA profiles of the 8 cell lines tested were different. They were characterized by the presence of several peaks (2 to 7) corresponding to different ploidy levels, by differences in the fluorescence intensity of each peak and by the proportion of cells in each peak. Two cell lines (Cf124 and BmN) were constituted of 2

1782. Analysis of the Functional Significance of Linkage Group Conservation in Drosophila Full Text available with Trip Pro

Analysis of the Functional Significance of Linkage Group Conservation in Drosophila Linkage groups, as defined by chromosome arms in Drosophila melanogaster, appear to have remained largely intact within the genus Drosophila and, possibly, within the higher Diptera per se. We hypothesized that linkage group conservation might have a functional basis (possibly related to interphase chromosome arrangement). To test this hypothesis, a series of autosomal 2-3 translocations were synthesized

1783. The effect of diet, sex and mating status on longevity in Mediterranean fruit flies (Ceratitis capitata), Diptera: Tephritidae. (Abstract)

The effect of diet, sex and mating status on longevity in Mediterranean fruit flies (Ceratitis capitata), Diptera: Tephritidae. Dietary Restriction (DR) extends lifespan in a range of model organisms such as yeast, flies and worms suggesting it is a 'public' mechanism for longevity extension. Lifespan extension has also been reported in the Mediterranean fruit fly (medfly), Ceratitis capitata in response to various types of dietary manipulation, however, the responses can be complex

1784. Bionomics of Aedes aegypti subpopulations (Diptera: Culicidae) from Misiones Province, northeastern Argentina. (Abstract)

Bionomics of Aedes aegypti subpopulations (Diptera: Culicidae) from Misiones Province, northeastern Argentina. Life statistics of four Aedes aegypti subpopulations from the subtropical province of Misiones were studied during autumn and winter, under semi-natural conditions, coming from the localities of Posadas (SW), San Javier (SE), Bernardo de Irigoyen (NE) and Puerto Libertad (NW). The eastern subpopulations are geographically separated by the central mountain system of the province from

1785. Genetic insights into the population structure of Culex pipiens (Diptera: Culicidae) in the Northeastern United States by using microsatellite analysis. (Abstract)

Genetic insights into the population structure of Culex pipiens (Diptera: Culicidae) in the Northeastern United States by using microsatellite analysis. Members of the Culex pipiens complex are considered as biting nuisance and vectors of important arbo-viruses including West Nile virus (WNV). To analyze the genetic structure of urban and rural populations of Cx. pipiens form pipiens and gain insights into behavioral implications, mosquitoes were collected from established WNV transmission foci

1786. Transstadial and horizontal transfer of bacteria within a colony of Anopheles gambiae (Diptera: Culicidae) and oviposition response to bacteria-containing water. (Abstract)

Transstadial and horizontal transfer of bacteria within a colony of Anopheles gambiae (Diptera: Culicidae) and oviposition response to bacteria-containing water. In a paratransgenic approach, genetically modified bacteria are utilized to kill the parasite in the vector gut. A critical component for paratransgenics against malaria is how transgenic bacteria can be introduced and then kept in a mosquito population. Here, we investigated transstadial and horizontal transfer of bacteria within

1788. Oral infection by Diptera larvae in children: a case report. (Abstract)

Oral infection by Diptera larvae in children: a case report. Oral myiasis is usually caused by flies of the order Diptera. One of the causes of human myiasis is Cochliomyia hominivorax, which is a true obligate parasite of mammals.A case of oral myiasis in a 5-year-old girl is reported. She presented with a swelling on the hard palate accompanied by intense pain and a fetid odor. A literature review of oral myiasis reports in children was performed.The poor oral hygiene, lip incompetence, open

1789. Evaluation of mosquito densoviruses for controlling Aedes aegypti (Diptera: Culicidae): variation in efficiency due to virus strain and geographic origin of mosquitoes. (Abstract)

Evaluation of mosquito densoviruses for controlling Aedes aegypti (Diptera: Culicidae): variation in efficiency due to virus strain and geographic origin of mosquitoes. Four mosquito densovirus strains were assayed for mortality and infectivity against Aedes aegypti larvae from different geographic regions. The viral titers were quantified by real-time PCR using TaqMan technology. Firstinstar larvae were exposed to the same titer of each densovirus strain for 48 hours. All strains

Morphological and enzymatic characterization of Phlebotomus perniciosus and Phlebotomus longicuspis in Morocco is reported. Twenty-nine localities in central and southern of Morocco were sampled and compared with three localities from the Rif (northern Morocco). For morphological study, sand flies were collected by sticky-paper traps. For males

1791. Population genetics and phylogeography of Aedes aegypti (Diptera: Culicidae) from Brazil. (Abstract)

Population genetics and phylogeography of Aedes aegypti (Diptera: Culicidae) from Brazil. Population genetic analyses were conducted using samples of Aedes aegypti from 14 localities in the north, southeast, northeast, and central regions of Brazil. An 852-bp region of the mitochondrial DNA cytochrome oxidase I (COI) gene was used in the analyses. Ten haplotypes were observed, and cluster analyses revealed 2 groups (lineages) separated by 8 fixed mutations, suggesting that the Brazilian Ae

1794. Life tables study of immature Aedes albopictus (Skuse) (Diptera : Culicidae) during the wet and dry seasons in Penang, Malaysia. (Abstract)

Life tables study of immature Aedes albopictus (Skuse) (Diptera : Culicidae) during the wet and dry seasons in Penang, Malaysia. Life tables were constructed for twelve cohorts of immature stages of the dengue vector Ae. albopictus in a wooded area of Penang, Malaysia.

1798. The diel oviposition periodicity of Aedes aegypti (L.) (Diptera: Culicidae) in the laboratory: substrate-movement effect. (Abstract)

The diel oviposition periodicity of Aedes aegypti (L.) (Diptera: Culicidae) in the laboratory: substrate-movement effect. The diel oviposition periodicity of females of the LSHTM strain of Aedes aegypti was studied, under laboratory conditions, using one female/cage and monitoring, by changing the substrate, every 1, 2, 4 or 24 h. The individual females monitored at hourly intervals showed peak oviposition at 18.00-19.00 hours (a period when 44% of the eggs observed were laid) whereas

1799. Limited interdecadal variation in mosquito (Diptera: culicidae) and avian host competence for Western equine encephalomyelitis virus (togaviridae: alphavirus). (Abstract)

Limited interdecadal variation in mosquito (Diptera: culicidae) and avian host competence for Western equine encephalomyelitis virus (togaviridae: alphavirus). Historically, western equine encephalomyelitis virus (WEEV) caused large equine and human epidemics in the Americas from Canada into Argentina. Despite recent enhanced surveillance for West Nile virus, there have been few reports of equine or human cases and little documented enzootic activity of WEEV. During the past three years, WEEV
