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 کاملInterspecific competition between larval Culex restuans Theobald and Culex pipiens L. (Diptera: Culicidae) in Michigan.
Many invasive species succeed in becoming established in new locations because of their competitive superiority to native species. This has been shown in several examples involving mosquitoes. In this study, we examined the interspecific competition between mosquito larvae of a well-established, non-native species, Culex pipiens, and those of its ecologically similar, native congener Culex rest...
متن کاملToxic Response of Mosquito Culex Quinquefasciatus (Diptera: Culicidae) to some Agricultural Pesticides (Butachlor and Pertilachlor)
Background: The expansion of herbicide used in aquatic ecosystems as well as in terrestrial if is not properly controlled may produce harmful effects on freshwater fisheries. Residue limits of these agricultural chemicals in tropical fishery waters should be established. The aim of this study was to determine the acute toxicity of butachlor and pertilachlor as potential dangerous herbicides to ...
متن کاملEssential oils of Satureja species: insecticidal effect on Culex pipiens larvae (Diptera: Culicidae).
The chemical composition of the essential oils of the wild growing plants of Greek S. spinosa L., S. parnassica subsp. parnassica Heldr.& Sart ex Boiss., S. thymbra and S. montana were determined by GC and GC/MS analysis. The larvicidal activities of the essential oils were assayed against Culex pipiens biotype molestus. The analytical data indicated that various monoterpene hydrocarbons and ph...
متن کاملEffects of density and larval competition on selected life history traits of Culex pipiens quinquefasciatus (Diptera: Culicidae).
The effects of larval densities of one to four individuals in standard Drosophila-vials (diameter 25 by 95 mm) on the age at pupation, starved dry weight, and wing length of Culex pipiens quinquefasciatus Say were studied. This approach required relatively few larvae per replicate and included a control treatment, where individual larvae developed in the absence of competition. This design also...
