Colonization and characterization of Anopheles culicifacies Giles, the major malaria vector in Sri Lanka

de Silva, B.G.D.N.K.; Ratnayake, W.E.; Gunasekera, M.B.; Abeyewickreme, W.; Karunanayake, E.H.; Wickremasinghe, M.B. (Museum and Reference Centre, SEAMEO-TROPMED National Centre of Thailand, 1993)
Development of DNA probes for the identification of sibling species A of the Anopheles culicifacies(Diptera Culicidae) Complex

Gunasekera, M.B.; de Silva, B.G.D.N.K.; Abeyewickreme, W.; Subbarao, S.K.; Nandadasa, H.G.; Karunanayake, E.H. (CABI Publishing, 1995)

Three highly repetitive DNA sequences, Rp36, Rp217 and Rp234, were isolated from A. culicifacies s.l. The cloned DNA sequences were found at a higher copy number in species B and C, than in species A of the A. culicifacies ...
Gene flow patterns among Aedes aegypti (Diptera: Culicidae) populations in Sri Lanka

Fernando, H.S.D.; Hapugoda, M.; Perera, R.; Black Iv, W.C.; de Silva, B.G.D.N.K. (MDPI AG, 2020)

ABSTRACT:In Sri Lanka, dengue is the most serious arboviral disease. Recent increases in dengue cases suggest a higher infection rate and spread of the disease to new areas. The present study explores gene flow patterns ...
ITS-2 secondary structures and phylogeny of Anopheles culicifacies species

Dassanayake, R.S.; Gunawardene, Y.I.N.S.; de Silva, B.G.D.N.K. (Biomedical Informatics Pub. Group, 2008)

BACKGROUND: Second internal transcribed spacer (ITS2) has proven to contain useful biological information at higher taxonomic levels. OBJECTIVES: This study was carried out to unravel the biological information in the ITS2 ...
Mitochondrial metabolic genes provide phylogeographic relationships of global collections of Aedes aegypti (Diptera: Culicidae)

Fernando, H.S.D.; Hapugoda, M.; Perera, R.; Black Iv, W.C.; de Silva, B.G.D.N.K. (Public Library of Science, 2020)

ABSTRACT: Phylogeographic relationships among global collections of the mosquito Aedes aegypti were evaluated using the mitochondrial Cytochrome C Oxidase 1 (CO1) and NADH dehydrogenase subunit 4 (ND4) genes including new ...
A Preliminary study of genetic estimates of population structure of Aedes aegypti populations in three districts, Sri Lanka

Fernando, H.S.D; Hapugoda, M.D.; de Silva, B.G.D.N.K. (Sri Lanka Association for the Advancement of Science, 2014)
Prevalence of Anopheline species in Ampara district, Sri Lanka

Fernando, M.A.S.T.; Gunathilaka, P.A.D.H.N.; Hapugoda, M.D.; de Silva, B.G.D.N.K.; Wijeyerathne, P.; Abeyewickreme, W. (University of Kelaniya, 2012)

Introduction: Investigating the presence of primary and secondary vectors of malaria in the selected areas where no entomological surveillance was carried out for about 30 years due to ethnic conflict. Objective: To study ...
Screening of Anopheles crlicifacies population of Sri Lanka for sibling species A.

de Silva, B.G.D.N.K.; Gunasekera, M.B.; Abeyewickreme, W.; Abhayawardena, T.A.; Karunanayake, E.H. (Thacker's Press and Directories for Indian Research Fund Association, 1998)

A total of 1119 Anopheles culicifacies mosquitoes collected from various malaria endemic regions in Sri Lanka were examined using two DNA probes Rp217 and Rp234, which enable the differentiation of sibling species A from ...
Seasonal Trends of Anopheles Culicifacies population at Gomadiyagala, a village in a North Western Province of Sri Lanka

de Silva, B.G.D.N.K.; Gunasekera, M.B.; Abeyewickreme, W.; Wickremasinghe, M.B. (University of Sri Jayewardenepura, 1998)
A Simplified non radioactive DNA probe technique for the field detection of sibling species A of the Anopheles culicifacies (Diptera: Culicidae) complex

de Silva, B.G.D.N.K.; Hapugoda, G.P.G.M.D.; Karunanayake, E.H. (University of Sri Jayewardenepura, 2010)

Three cloned highly repetitive DNA sequences Rp36, Rp217 and Rp234 isolated from An. culicifacies Giles, sensu lato were developed as non radioactive DNA probes by using a biotinylated labeling and colorimetric detection ...
Study on house dwelling Anopheline species in Batticaloa District, Sri Lanka

Fernando, M.A.S.T.; Gunathilaka, P.A.D.H.N.; Hapugoda, M.D.; Abeyewickreme, W.; de Silva, B.G.D.N.K.; Wijeyerathne, P. (University of Kelaniya, 2011)

Even though the malaria cases are less, vectors which transmit the disease are still present. No proper vector surveys have been carried out in the eastern area of Sri Lanka for more than 30 years, due to the ethnic ...
