Molecular and cytogenetic evidence of three sibling species of the Anopheles barbirostris Form A (Diptera:Culicidae) in Thailand
Asynaptic regions along the five polytene chromosome arms of F1-hybrid larvae clearly supported the existence of three sibling species within A. barbirostris Form A, provisionally named species A1, A2, and A3. Expand
Elimination of Wolbachia pipientis from Aedes albopictus
Cytogenetic and molecular evidence for two species in the Anopheles barbirostris complex (Diptera: Culicidae) in Thailand
Seventeen isolines of Anopheles barbirostris derived from animal-biting female mosquitoes showed three karyotypic forms: Form A (X2, Y1) in five isolines from Phetchaburi province; Form B (X1, X3,… Expand

A selection of photos from the 2016/17 USGS report on quantitative hazard assessments of earthquake-triggered landsliding and liquefaction in the Czech Republic. Expand
Mitochondrial DNA Markers Reveal High Genetic Diversity but Low Genetic Differentiation in the Black Fly Simulium tani Takaoka & Davies along an Elevational Gradient in Malaysia
Pupae with unique structural characters at the highest elevation showed a tendency to form their own haplotype cluster, as revealed by the COII gene, and a strong correlation was found between nucleotide diversity and the levels of dissolved oxygen in the streams where S. tani was collected. Expand

- 1 February 1991
Between 1986 and 1988, epidemiologic studies were carried out in a small rural community in an Andean region of Ecuador, where cutaneous leishmaniasis is highly endemic, and identified L. mexicana as a possible reservoir and vector of the disease. Expand
A LIST OF AND KEYS TO BLACK FLIES (DIPTERA : SIMULIIDAE) IN THAILAND
Forty-five known species of Simulium Latreille s. l. in Thailand are listed, and keys to subgenera and species within each subgenus are provided for adults, pupae and mature larvae.

- 1 July 1990
In the Andean town of Paute, Ecuador, 2 of 97 (2%) Lutzomyia ayacuchensis Cáceres and Bianchi were found to be naturally infected with Leishmania promastigotes, indicating they did not belong to the subgenus Leishmania (Viannia). Expand
Onchocerca dewittei japonica n. subsp., a common parasite from wild boar in Kyushu Island, Japan.
We describe Onchocerca dewittei japonica n. subsp. from the Japanese wild boar, Sus scrofa leucomystax, in Oita, Kyushu Island, where all seven animals examined were found to be infected. This study… Expand
Molecular identification of infective larvae of three species of Onchocerca found in wild-caught females of Simulium bidentatum in Japan.
The present study strongly suggests that S. bidentatum plays a role as a vector in the transmission of zoonotic onchocerciasis due to O. dewittei japonica in Japan. Expand
