Impacts of rubber factory wastewater on the stream macrobenthic assemblages

Dilhara, K. G. A.; Chandrasekara, W. U. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

In this study, we assessed how the rubber factory wastewater effluents change the water quality and sediment quality parameters in some factory-associated streams, namely the Aswathu Oya, Gurugoda Oya, and Rakwatthe Ela, ...
Diversity of midgut symbiotic bacteria in Aedes mosquito genera: A meta-analysis

Kumari, J. Y.; Amarasinghe, L. D.; Udayanga, N. W. B. A. L.; Ranasinghe, H. A. K. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

The gut bacterial composition of mosquitos has the capability of altering mosquito pathogen transmission through numerous mechanisms, which is useful in novel transmission control strategies. Therefore, understanding the ...
Evaluation of toxic metal contamination in surface sediments and water in Mahakanadarawa tank; Anuradhapura, Sri Lanka

Sampath, M.; Perera, R. T.; Perera, R. A.; Liyanage, J. A.; Premaratne, W. A. P. J. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

Toxic elements, including heavy metals/metalloids, readily contaminate water reservoirs via natural mechanisms such as surface runoff, precipitation, and atmospheric deposition. As a result, some toxic metals can be ...
Assessment of human health risk of cylindrospermopsin by consuming Oryza sativa (rice) from selected CKDu endemic areas in Sri Lanka

Bandara, W. M. S. N.; Wanigatunge, R. P.; Rajapaksha, A. U.; Vithanage, M. S.; MaganaArachchi, D.N. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

The proliferation of toxic cyanobacterial blooms in freshwater bodies can seriously threaten human health. Many studies have been carried out on cyanotoxins in water sources, but studies on cyanotoxins in terrestrial plants ...
Alleviation of drought stress on immature tea (Camellia sinensis) plants by exogenous application of Abscisic acid (ABA)

Damayanthi, M. M. N.; Wijeratne, T. L.; Damunupola, J. W. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

Phytohormones are chemical substances regulating various physiological and biochemical processes in plants. Abscisic acid (ABA) plays a major role in response to drought stress. This study was done to identify the role of ...
Alternative gelling agents to develop cost effective medium for in vitro propagation of Dendrobium cv. “Big Jumbo White”

Kanishka, W. S.; Lakmali, G. B. T.; Umesha, M. S. P.; Priyadarshan, A. I. S.; Senanayake, S. P. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

In vitro propagation is the most common method of Dendrobium propagation. Commonly, agar is used as an effective gelling agent though, it is expensive. However, the developing a cost-effective method is beneficial for ...
Formulation of a low-cost organic fertiliser paste from selected invasive plants enriched with Trichoderma species for the cultivation of Raphanus sativus

Kalpani, N. N.; Kannangara, B. T. S. D. P.; Ratnayake, R. M. C. S. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

Excessive use of synthetic fertilisers is a significant drawback in modern agriculture, and it has several negative outcomes; unfavourable environmental effects and adverse impacts on human health and agriculture. The ...
First report of Culex (Lophoceraomyia) cinctellus in Sri Lanka

Rangana, U. L. P.; Kumarasinghe, K. G. D. S. G. S.; Jayasinghe, H. P. N. T.; Refai, F. W.; Udayanga, N. W. B. A. L.; Ranathunge, R. M. T. B. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

Disease epidemics caused by mosquito vectors have been a significant challenge faced by the health sector of Sri Lanka. Routine entomological surveillance is practised as a key approach in monitoring the population dynamics ...
Diversity of microbiota associated with dengue vector mosquito breeding habitats in Udapalatha MOH Division, Sri Lanka

Kumari, J. Y.; Amarasinghe, L. D.; Ranasinghe, H. A. K. (Kumari J. Y.; Amarasinghe L. D.; Ranasinghe H. A. K.; (2021), Diversity of microbiota associated with dengue vector mosquito breeding habitats in Udapalatha MOH Division, Sri Lanka, Proceedings of the International Conference on Applied and Pure Sciences (ICAPS 2021-Kelaniya) Volume 2, Faculty of Science, University of Kelaniya Sri Lanka. Page 3., 2022)

Microbiota associated with mosquito breeding habitats are among biotic factors and serve as parasites, pathogens, predators, competitors, non-competitors, and food items for developing larvae. Therefore, there are naturally ...
Use of morphological and molecular methods in identification of Asian bush mosquito, Aedes japonicus (Theobald, 1901), in Sri Lanka

Wickramasinghe, T. K. C.; Udayanga, N. W. B. A. L.; Manamperi, A. A. P. S.; Hapugoda, M. D.; Karunarathna, K. H. T.; Ranathunge, R. M. T. B. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)

Conducting routine entomological surveillance to identify new vectors and changes in the distribution patterns of vectors is important for the management of mosquito borne diseases in Sri Lanka. A recent preliminary ...
Troop composition of free-ranging Toque macaque in dry and wet zones of Sri Lanka: reviewed by a multivariate method using R

Weerasekara, W. M. L. S.; Wijesooriya, W. M. K. B.; Britto, C. S. A.; Ranawana, K. B. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)
