Antagonist Potential of Vorticella microstoma on the larval development of Culex gelidus and Aedes aegypti

Ranasinghe, H.A.K.; Amarasinghe, L.D. (19th Conference on Postgraduate Research, International Postgraduate Research Conference 2018, Faculty of Graduate Studies,University of Kelaniya, Sri Lanka, 2018)

Selection of effective biological agents which can suppress the growth of immature stages of mosquito vectors has drawn a wide attention in disease control programmes. Vorticella microstoma is a parasitic ciliate which has ...
Density and diversity of mosquito larvae associated with rice field and marshland habitats in two climatically different areas in Sri Lanka

Amarasinghe, L.D.; Weerakkodi, W.G.I.S. (International Journal of Entomological Research, 2014)

Rice field and marshland habitats have significant influence on production of mosquito larval populations including vector mosquitoes and hence the disease transmission. Study revealed that mosquito larval density in rice ...
Effect of aqueous extracts of Annona glabra plant and extracellular metabolites of two Trichoderma species on the survival of larval Culex quinquefasciatus and eggs of Aedes aegypti

Aberathna, A. A. A. U.; Ranasinghe, H. A. K.; Rajapaksha, R. D. T.; Amarasinghe, L. D. (Research Symposium on Pure and Applied Sciences, 2018 Faculty of Science, University of Kelaniya, Sri Lanka, 2018)

Phytochemicals constitute a rich source of bioactive chemicals and some microbial products carry selective toxicity to many insect species, hence those are considered as alternatives to chemical insecticides. This study ...
Efficacy and potential use of VectoBac WGr for the control of Culex quinquifaciatus mosquitoes in three different localities of Gampaha district, Sri Lanka

Wijegunawardana, N.D.A.D.; Hapangama, H.A.D.C.; Gunawardene, Y.I.N.S.; Manamperi, A.; Abeyewickreme, W. (Sri Lanka Association for the Advancement of Science, 2009)

Some methods of mosquito population control, especially the application of pesticides for adult mosquitoes, can have an impact on the environment and individuals with a heightened sensitivity to pesticides. Of the available ...
Molecular characterization of culturable aerobic bacteria in the midgut of field-caught Culex tritaeniorhynchus, Culex gelidus, and Mansonia annulifera mosquitoes in the Gampaha district of Sri Lanka

Gunathilaka, N.; Ranasinghe, K.; Amarasinghe, D.; Rodrigo, W.; Mallawarachchi, H.; Chandrasena, N. (Hindawi Pub. Co., 2020)

Background: Larval and adult mosquito stages harbor different extracellular microbes exhibiting various functions in their digestive tract including host-parasite interactions. Midgut symbiotic bacteria can be genetically ...
Patterns of monthly Culex mosquito density variation in Gampaha district, Sri Lanka.

Wijegunawardana, N.D.A.D.; Gunawardene, Y.I.N.S.; Manamperi, A.; Abeyewickreme, W. (Faculty of Tropical Medicine, Mahidol University, 2009)

BACKGROUND: The ecology, development, behavior, and survival of mosquitoes and the transmission dynamics of the diseases they transmit are strongly influenced by climatic factors. OBJECTIVE: The objective of this study was ...
Prevalence of micro-fauna associated in rice field habitats in Kurunegala district in Sri Lanka and potential mosquito larvicidal effect of Vorticella microstoma

Ranasinghe, H. A. K.; Amarasinghe, L. D. (Research Symposium on Pure and Applied Sciences, 2018 Faculty of Science, University of Kelaniya, Sri Lanka, 2018)

Micro-fauna are associated with most of the mosquito larval breeding habitats in tropical climate. There may be parasitic, pathogenic or even predatory species among these biota to mosquito larvae and their potential use ...
Vector mosquito diversity and habitat variation in a semi-urbanized area of Kelaniya in Sri Lanka

Amarasinghe, L.D.; Dalpadado, D.R. (International Journal of Entomological Research, 2014)
