Taxonomic study of the Drosophila auraria species complex (Diptera: Drosophilidae) with description of a new species
No full textThe Drosophila auraria species complex, especially from the Ryukyu archipelago and Taiwan, was reviewed. A new species, D. neoasahinai Watada and Kondo, sp. nov., was described from Okinawa-jima and surrounding islands. Two synonymies were proposed on the basis of the present and previous morphological comparisons and cross experiments; D. yuwanensis Kim and Okada, 1988, as a junior synonym of D. asahinai Okada, 1964, and D. quadraria Bock and Wheeler, 1972, as a junior synonym of D. triauraria Bock and Wheeler, 1972. A laboratory stock (no. 14020-0011.01) maintained in the Drosophila Species Stock Center at the University of California, San Diego and so far designated as D. rufa Kikkawa and Peng, 1938, was identified as D. tani Cheng and Okada, 1985, based on morphology
A list of drosophilid flies collected in Ehime prefecture, Japan
No full textWe collected drosophilid flies from 2011 to 2012 in Ehime prefecture, Japan and summarized our and the previous records. In the present study, 82 species of the drosophilid flies were recorded in our collection, and 19 species belonging to 9 genera of them were newly recorded in Shikoku. The new records were comprised of the species of Stegana, Leucophenga, Paraleucophenga, Dichaetophora, Mycodrosophila, Phorticella, Chymomyza, Hirtodroso-phila and Lordiphosa. As a result, a total of 101 species belonging to 20 genera of the Drosophilidae were recorded from the present and previous surveys in Ehime prefecture
Mass Transfer with Simultaneous Chemical Reaction in Drops for Liquid-Liquid Systems
No full textTitle: Mass Transfer with Simultaneous Chemical Reactions in Drops fir Liquid-Liquid Systems, Author: Hideki Watada, Location: ThodeThis dissertation is divided into three major self-contained
sections. The first one contains a review of previous work in the
field of mass transfer in drops for liquid-liquid systems. The second section outlines the numerical solutions of the
continuity equation for for forced convection with simultaneous chemical
reaction in the dispersed phase. The solutions are compared with those
predicted by existing theoretical models for mass transfer in the
dispersed phase. The third section describes the experimental equipment and
method of operation. Physical mass transfer in drops is studied
initially. This established a basis for evaluation the effect of
chemical reaction on the rate of mass transfer in a later study. The results from these experimental studies are used to test the ability
of existing models to predict mass transfer with simultaneous chemical
reaction in drops.ThesisDoctor of Philosophy (PhD
Faunal and seasonal surveys on drosophilid flies by net sweeping in Ehime Prefecture, Shikoku, Japan
No full textA faunal survey on drosophilid flies by net sweeping was carried out in Ehime Prefecture, Shikoku, Japan from October 2009 to October 2010. A total of 11,663 individuals of 54 species belonging to 15 genera were collected by the year-round samplings at two localities, Dogo Park and Mt. Miyukiji, and occasional ones at another site in Matsuyama. The most abundant species was Liodrosophila aerea (49%), followed by Drosophila rufa (17%), D. lutescens (9.6%), D. sternopleuralis (4.0%) and D. bizonata (3.8%). The six dominant species showed more or less similar patterns in seasonal population fluctuation, being abundant in spring and/or fall with some variation between the localities. The observed seasonal patterns of drosophilid flies are discussed in relation to the extraordinary hot weather in the summer of 2010
