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

Hybridization Of Aedes (Protomacleaya) Zoosophus With Ae. (Pro.) Triseriatus Group Species: Hybrid Morphology, David Taylor
David B. Taylor
Morphology of hybrids between Aedes (Protomacleaya) zoosophus and Ae. (Pro.) triseriatus group species is described. Adult females of hybrids key to Ae. zoosophus. Hybrids are differentiated from Ae. zoosophus by the dark longitudinal medial or submedial lines on the thorax and by the reduced width of the light tarsal and abdominal bands. The transverse band of light scales on the anterior scutum is complete in Ae. hendersoni / Ae. zoosophus hybrids and incomplete in Ae. triseriatus / Ae. zoosophus hybrids. Aedes brelandi / Ae. zoosophus hybrids are similar to Ae. hendersoni / Ae. zoosophus hybrids. However, due to the …

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 …

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 …

An intensive mosquito survey of St. Joseph County, Indiana, was undertaken in 1976 to provide information on mosquito diversity, distribution, and abundance within the area. Location of larval breeding sites was emphasized, supplemented by a New Jersey light-trap program and man-bait collections. Over 2000 larval sites were identified in the 500 square-mile area.
Of the 52 species of mosquito known to occur in Indiana, 35 (8 genera) are endemic to St. Joseph County. Larval sites for most species were identified within the county, and 31 species were represented in the light-trap collections.
