KACHVORYAN & DOREEN WERNER 1 ON THE DISTRIBUTION OF BLACKFLY LARVAE IN DIFFERENT RIVERS IN LITHUANIA RASA BERNOTINĖ 2 INITIAL PRACTICAL EXPERIENCE WITH THE DIGITAL KEY TO THE LARVAE AND PUPAE OF SIMULIIDAE FROM CENTRAL AND WESTERN EUROPE MANFRED CAR & W...

Eleven polymorphic microsatellite loci were isolated and developed from the black fly, Simulium negativum, a member of the Simulium arcticum sibling species complex. The observed heterozygosity of the 11 loci ranged from 0.03 to 0.83. The number of alleles per locus ranged from 8 to 19. Significant linkage disequilibria were encountered only for the primer pairs BF7-1 with BF7-5 and BF6-32 with...

We developed a molecular assay to detect predation on Anopheles gambiae sensu lato (s.l.) mosquitoes. This intergenic spacer ribosomal DNA polymerase chain reaction assay and restriction enzyme analysis uses An. gambiae-specific primers to detect mosquito DNA in the DNA extracts from whole invertebrate predators, which enables identification of species (An. gambiae s.s. versus An. arabiensis) a...

A mechanism is described that enables a specimen to be tilted through a known angle and continuously observed under the highest power of the optical microscope. Objects can thus be localized accurately in space. This facility in conjunction with serial optical sectioning by Nomarski optics has been used to construct models of the arrangement of polytene chromosomes in nuclei of Drosophila, Simu...
