hybrid compatibilities and susceptibility of culex pipiens fatigans wied. to wuchereria bancrofti (cobbold) in east africa.tests with colonies of culex pipiens fatigans from six localities in kenya and tanzania revealed high levels (60-90%) of susceptibility to infection with wuchereria bancrofti. twenty-six of 30 possible crosses between these colonies were performed and revealed no cases of incompatibility. all but 2 crosses produced near-normal sex ratios of f(1) adults, with a slight excess of females in 16 of 20 detailed assessments. the implications of these results for control work and filariasis transmission ...19724538541
experimental introduction of a microsporidian into a wild population of culex pipiens fatigans wied.chemical control of c. p. fatigans frequently fails because the mosquito rapidly develops resistance to insecticides. a possible alternative or complementary method is biological control, including the introduction of pathogens. the microsporidian plistophora culicis was known to infect readily and have an adverse effect on c. p. fatigans populations in the laboratory, so an attempt was made to introduce and establish this pathogen in a wild population of the mosquito on the pacific island of na ...19724538542
chemosterilization of culex pipiens fatigans wiedemann by exposure of aquatic stages. 3. induction of dominant lethal mutations in the f 1 generation by certain aziridines, phosphoramides, and s-triazines.in insects it is known that the chemosterilant treatment induces dominant lethal mutations which bring about embryonic death. the possibility of delayed expression of the chemosterilant-induced dominant lethals in f(1) progeny of the tropical house mosquito, culex pipiens fatigans wiedemann has been investigated. the chemosterilants employed were 8 aziridinyl compounds, 3 phosphoramides, and 4 s-triazines. in general, all the chemosterilants tested were found to cause different degrees of mortal ...19724539817

entomological aspects of filariasis control in sri lanka.historical events and suitable environmental conditions in the southwestern coastal areas of sri lanka have led to the establishment of a zone of endemic filariasis caused by wuchereria bancrofti and transmitted by culex pipiens fatigans. the previous brugia malayi foci, scattered over widely dispersed areas of the island, were apparently completely eliminated as a result of control of the mansonia vectors by the destruction of the larval host plants in their swamp habitats. control measures by ...19744619057
population replacement in culex fatigens by means of cytoplasmic incompatibility. laboratory experiments with non-overlapping generations.bidirectional cytoplasmic incompatibility in the culex pipiens complex appears to provide a mechanism for the replacement of a wild population by a strain refractory to filaria or a strain made partly sterile by a translocation. as a preliminary test of the feasibility of the replacement process, various ratios of strains with the cytoplasm of either delhi or paris, which are bidirectionally incompatible, were tested in laboratory cages. where one strain was marked with the ruby-eye gene, this s ...19744549348

comperative studies with culex pipiens egg rafts. immunogenetic, electrophoretic and enzymatic analysis of unfertilized, compatible and incompatible fertilized eggs.by applying immunologic, electrophoretic and enzymatic methods, extracts of different raft types of culex pipiens were analysed. rafts of the crosses pa x pa and ha x ha contained four common antigens, while unfertilized rafts of pa and ha (no antisera were prepared against them) and rafts of the crosses og x og, og x pa, and pa x og shared three common antigens with the remaining raft extracts. disk-electrophoresis of raft extracts in acrylamide gel resulted in different electropherograms. ten ...197424425457
transovarial transmission of rickettsia-like microorganisms in mosquitoes.the wolbachiae found in culex pipiens and the tafahi strain of the a. scutellaris group are small rickettsia-like symbionts of the gonads. they are extrachromosomal self-replicating units that are vertically transmitted through the ovaries. their presence in the only two groups of mosquitoes known to exhibit incompatibility, the fact that they are found in only the tafahi strain, and the loss of incompatibility after removal of wolbachia in c. pipiens are compelling evidence for the role that wo ...197520018
[occurrence of culex pipiens molestus forsk. in populated areas of the leningrad region].the mosquitoes of culex pipiens molestus first recorded from leningrad as far as 30 years ago have been reported from the settlements of the leningrad district since 1965. the most northern point of their occurrence is marked at 60 degrees 45' n and is removed from leningrad for over 120 km. such spread of mosquitoes to new settlements is associated with the development of multistory housing construction in the country and delivery of imagos from leningrad to the settlements of the district by m ...1975124848
[experience in the control of the mosquito culex pipiens molestus forsk. in leningrad].systematic control of mosquitoes (c. p. molestus) has begun in leningrad since 1968 when undertaken inspections revealed mosquitoes and their aquatic stages in 21.8% of basements. all hatching sites of mosquitoes were registered and sanitary, hydrotechnical and destroying measures were carried out there. during the period of 1968 to 1973 the basements were cleaned, in 509 of them hydroisolation was made and many were dried. anually chemical treatment of basements was undertaken and for 6 years t ...1975127154
esterase polymorphism and sensitivity to dursban organophosphorus insecticide in culex pipiens pipiens populations.esterase polymorphism and dursban (o,o-dimethyl-2-pyridylphosphorothioate) sensitivity have been investigated in 12 natural populations and three laboratory strains of culex pipiens pipiens. this mosquito has two esterase loci, est-1 and est-2, which were shown to code esterases of the b group (aliesterases) but not cholinesterases. no correlation between est-1 polymorphism and dursban sensitivity was found, but the increase of the est-2(0.64) allele in the populations less sensitive to dursban ...197554163
