Mosquito (Diptera: Culicidae) Fauna Of The Velyka Dobron' Game Reserve (West Ukraine) With New Distribution Data And Medical Risk Assessment, Kálmán Szanyi, Antal Nagy, Attila Molnár, László József Szabó, Szabolcs Szanyi

Turkish Journal of Zoology

The distribution of mosquito species in the Transcarpathian part of Ukraine is poorly studied. Here we present the results of a four-year survey carried out in the Velyka Dobron' Game Reserve, and provide the actualized checklist of the Transcarpathian Culicidae fauna containing 32 species. Four of the sampled species have not been formerly known in Transcarpathia: Anopheles hyrcanus, Ochlerotatus cataphylla, Ochlerotatus nigrinus, Uranotaenia unguiculata. Based on quantitative composition of studied assemblage, vector potential of species and distribution of transmitted pathogens we evaluate the medical and veterinary risk caused by mosquitoes in Transcarpathian region.

The Fauna And Ecology Of Mosquito Larvae (Diptera: Culicidae) In Western Iran, Omid Banafshi, Mohammad Reza Abai, Hossein Ladonni, Hassan Bakhshi, Hadi Karami, Shahyad Azari Hamidian

Turkish Journal of Zoology

Ecological data are important in integrated vector management. There are few published documents about the ecology of mosquitoes (Diptera: Culicidae) in western Iran. To study the fauna and ecology of the mosquito larvae of Kurdistan Province, the samples were collected by the dipping method during June-October 2005 and June-August 2006. Larval habitat characteristics were recorded according to habitat type, water conditions (stagnant or running, clear or turbid), water temperature, vegetation (with or without vegetation), and sunlight exposure (full or partial sunlight or shaded). A total of 2096 third- and fourth-instar larvae were collected. Four genera and 11 species were identified: …

Genetics Of Interspecific Hybridization In The Triseriatus And Zoosophus Groups Of The Aedes (Protomacleaya) (Diptera: Culicidae)., David B. Taylor

David B. Taylor

Interspecific hybridization was used to examine the genetics of species divergence and phylogeny of mosquitoes in the Triseriatus and Zoosophus groups of Aedes (Protomacleaya). Aedes zoosophus Dyar & Knab exhibited a relatively high degree of reproductive compatibility with Triseriatus group species. Crosses between A. zoosophus and A. triseriatus (Say) produced fertile female and sterile, intersex, male progeny. Crosses between A. zoosophus females and A. brelandi Zavortink males were sterile with no egg embryonation observed. Crosses between A. zoosophus males and A. brelandi females and reciprocal crosses between A. zoosophus and A. hendersoni (Cockerell) produced sterile, intersex female and …

Genetic Compatibility Of Aedes (Protomacleaya) Triseriatus With A. (P.) Brelandi And A. (P.) Hendersoni (Diptera: Culicidae)., David B. Taylor

David B. Taylor

Interspecific hybridization was used to examine reproductive compatibility of Aedes (Protomacleaya) triseriatus (Say) with Aedes (P .) brelandi Zavortink and Aedes (P.) hendersoni Cockerell. Most male progeny were sterile intersexes when A. brelandi or A. hendersoni males were crossed with A. triseriatus females. Female hybrids, and males from the reciprocal crosses, were morphologically normal and fertile. Varying percentages of intersex males were observed among progeny when normal F₁ hybrids were crossed to either parental species or with other hybrids. Egg and female sterility resulting from a partial incompatibility between A. triseriatus cytoplasm and …

Unidirectional Reproductive Incompatibility Between Aedes (Protomacleaya) Brelandi And A. (P.) Hendersoni (Diptera: Culicidae)., David Taylor, George Craig

David B. Taylor

Forced mating was used to determine reproductive compatibility between two species in the Triseriatus Group of Aedes (Protomacleaya). In the cross between A. hendersoni Cockerell females and A. brelandi Zavortink males, only 7% of the females laid eggs that developed embryos. Furthermore, <5% of the eggs from single-female clutches in which one or more eggs did embryonate were fertile. In the reciprocal cross, A. brelandi females crossed to A. hendersoni males, 70% of the females laid fertile eggs and >80% of the eggs from those females became embryonated. Approximately 80% of the females were inseminated in both of the reciprocal crosses. No chromosomal abnormalities were observed in the hybrids. Incompatibility between the A. brelandi male genome and the A. …

Speciation In The Aedes Triseriatus Species Complex, David B. Taylor

David B Taylor

Interspecific hybridization was used to determine the genetic relationships between the four species of mosquitoes in the Triseriatus and Zoosophus groups of the aedine subgenus Protomacleaya (Diptera: Culicidae). Four factors were investigated: 1) fertility of intra- and interspecific crosses, 2) morphology of the interspecific hybrids and the genetic bases of morphological characters, 3) modes of postcopulatory reproductive isolation and 4) types of chromosomal changes occurring during and subsequent to the divergence of the species. Hybrid progeny were produced in 11 of the 12 possible crosses between the four species. Only the Aedes zoosophus female X A. brelandi male cross failed …
