Genetic differences between Culex pipiens f. molestus and Culex pipiens pipiens (Diptera: Culicidae) in New York.
The definition and phylogenetic placement of the autogenous molestus form of Culex pipiens has puzzled entomologists for decades. We identified genetic differences between Cx. p. pipiens (L.) and Cx. pipiens f. molestus Forskål in the SH60 fragment described previously. Single-strand conformation polymorphism analysis, cloning, and sequencing of this fragment demonstrated high polymorphism with...
متن کاملDevelopment of the immature stages of Culex (Culex) saltanensis Dyar (Diptera, Culicidae) under laboratory conditions
Development of the immature stages of Culex (Culex) saltanensis Dyar (Diptera, Culicidae) under laboratory conditions. Culex (Culex) saltanensis Dyar, 1928 is becoming frequent and abundant in natural and artificial breeding sites in urban and rural areas of Brazil. This study contributes to the knowledge of the biology of a Brazilian strain of C. saltanensis. The development of specimens reare...
متن کاملNitrate Reductase in Barley Roots under Sterile, Low Oxygen Conditions.
Levels of nitrate reductase activity (EC 1.9.6.1.) as high as 11 mumoles nitrite produced/hour gram fresh weight were found in barley (Hordeum vulgare cv. Compana) roots grown under low oxygen conditions. Roots of plants given identical treatment under sterile conditions did not develop the high levels of nitrate reductase activity. The results suggest that the buildup of particulate, reduced v...
متن کاملthe salivary gland chromosomes of culex pipiens molestus
the polygene chromosomal pattern together with the somatic and meiotic chromosomes of the autogenous tehran strain of culex pipiens molestus is described. the first and third chromosomes are metacentric, the second one is slightly submetacentric. each chromosome has well-defined, large puffed characteristic centromeres. randomly distributed asynaptic regions on the polytens chromosomes are ind...
متن کاملFirst Nationwide Surveillance of Culex pipiens Complex and Culex torrentium Mosquitoes Demonstrated the Presence of Culex pipiens Biotype pipiens/molestus Hybrids in Germany
Mosquitoes and other arthropods may transmit medically important pathogens, in particular viruses such as West Nile virus. The presence of suitable hosts and competent vectors for those zoonotic viruses is essential for an enzootic transmission, which is a prerequisite for epidemics. To establish reliable risk projections, it is an urgent need for an exact identification of mosquito species, wh...
