| [molecular genetic methods for the identification of the urban mosquito culex pipiens pipiens f. molestus (diptera, culicidae)]. | molecular genetic methods for the identification of two ecotypes, or forms (pipiens and molestus) of the culex pipiens pipiens mosquitoes, which are known as active bloodsuckers and vectors of various agents of diseases, are proposed. for the dna analysis, two populations of the urban mosquitoes (the molestus ecotype) from st. petersburg and moscow and two populations from the overground reservoirs in the leningrad province and neighboring areas of moscow (the pipiens ecotype) have been studied. ... | 2004 | 15553770 |
| [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 ... | 1975 | 127154 |
| [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 ... | 1975 | 124848 |
| [seasonal dynamics of oviposition in non-autogenous population of culex pipiens pipiens (diptera: culicidae) in the leningrad province]. | seasonal patterns of oviposition in a synanthropic unautogenous population of culex pipiens pipiens mosquitoes from 69 suburban settlements (60 degrees 30' n, 30 degrees e') of the leningrad province were studied during the period 1998-2002 years. the numbers of egg rafts laid in six artificial pools (barrels) were counted every day; altogether 692 rafts were collected. the general patterns of oviposition activity were similar for all studied years, in spite of their differences in the summer te ... | 2003 | 14658306 |
| [change in the autogeny of a leningrad population of culex pipiens molestus (culicidae)]. | eight year observations on the autogeny of c. p. molestus have shown that the per cent of autogenous females decreased from 87% (1968) to 25.6% (1976). the population of c. p. molestus from basement apartments of leningrad can be expected to receive a replenishment from free-living c. pipiens. | 1978 | 149939 |
