| dna barcoding of tropical black flies (diptera: simuliidae) of thailand. | the ecological and medical importance of black flies drives the need for rapid and reliable identification of these minute, structurally uniform insects. we assessed the efficiency of dna barcoding for species identification of tropical black flies. a total of 351 cytochrome c oxidase subunit 1 sequences were obtained from 41 species in six subgenera of the genus simulium in thailand. despite high intraspecific genetic divergence (mean = 2.00%, maximum = 9.27%), dna barcodes provided 96% correct ... | 2014 | 24112561 |
| cytotaxonomy of simulium siamense takaoka and suzuki (diptera: simuliidae) in thailand. | larval polytene chromosomes of 1824 individuals of simulium siamense takaoka and suzuki from 32 locations in northern, northeastern, eastern, and central thailand were examined. differences in sex chromosomes, fixed inversions, and the kind and frequency of floating inversions revealed five cytoforms (a, b, c, d, and e). in contrast to most simulium species, females of s. siamense are the heterogametic sex (zw) and males are the homogametic sex (zz). cytoform a differs from the others by having ... | 2008 | 19088811 |
