Abstract

The P-M system of hybrid dysgenesis in Drosophila melanogaster was investigated on the basis of gonadal dysgenesis using 1590 strains from 28 natural populations in Japan, and 20 populations from Southeast Asia, the Pacific area and Africa. Strong P strains were found sporadically in several...

Abstract

The distribution of polymorphic gene duplication at the Gpdh (glycerol-3-phosphate dehydrogenase) locus was studied in populations of Drosophila melanogaster (derived from North Carolina and Texas and from Okinawa, Japan) and 2 sibling species. Duplication was not observed in chromosome lines of D. ...

Abstract

Reproductive isolation and morphological differences among allopatric populations of the Holarctic species Drosophila testacea indicate that this taxon is actually a complex of 3 morphocryptic species: D. testacea, from Europe and continental Asia; D. orientacea sp. nov. from Japan; and D....

Abstract

The degree of sexual and reproductive isolation among 3 species of mosquitoes: A. riversi, occurring in Okinawajima and Iriomotejima, Ryukyu Archipelago, and Tsushima, Kyushu, Japan; A. alcasidi from Taiwan; and A. scutellaris from Papua New Guinea, was evaluated by "hide-and-seek" tests and...

Abstract

The incidence of puparial diapause was examined in B. peregrina, B. javanica, B. nathani, B. septentrionalis, B. karnyi, B. koimani, B. timorensis, B. formosensis and B. invaria collected from various localities in East Asia and Oceanian islands. Colonies of B. septentrionalis, B. nathani and B....

Abstract

A restriction map was constructed of the ribosomal cistron in A. albopictus. The 18s, 28s and nontranscribed spacer (NTS) regions were subcloned and used to probe for intraspecific variation. Seventeen populations were examined throughout the world range of the species: from Mauritius, Japan,...

Abstract

An account is given of the dispersal of Chrysomya megacephala from South-East Asia and Australasia to Africa, South America and Japan, as well as of the origins of the synanthropic form of the fly. The phylogeny of the C. megacephala group is discussed, and keys are presented to distinguish species ...

Abstract

Haploid nuclear DNA of 23 species of Aedes, as determined by Feulgen cytophometry, was found to vary 3-fold. This was accompanied by a 2-fold variation in total chromosome length. There was a significant correlation (r = 0.765, P < 0.001) between these two parameters. Genome size varied from...
