NaOCL for 10 min.) but required more rigorous sterilisation methods. Leaf explants collected from the trees growing in the wild could not be sterilised using different concentration of NaOCL[(10, 15, 20, 25)perc.] HgCl2,[(0.1, 0.5, 1)perc.] for different time intervals (5, 10, 15, 20, and 30 mins) but could be sterilised by combining HgCl2 and NaOCL (0.1perc. HgCl2 for 5 min followed by 10perc. NaOCL for 10 min). Leaf damage was observed when 70perc. ethanol was used as a pre-treatmentItem Effect of the mosquito larvicide, abate (temephos) on fingerlings of Oreochromis mossambicus (Peters)(National Science Council:Colombo, 1992) Pathiratne, A.; Ranasinghe, J.M.Item Insecticidal activity of some medicinal plants of Sri Lanka(Natural Resources Energy Science Autority:Colombo, 1997) Hewage, C.M. and othersItem Cyperenoic acid and (-)-hardwickiic acid from the chloroform extract of the roots of Croton aromatics:isolation and insecticidal properties(National Sceince Council:Colombo, 1990)Item Toxicity of fenthion in lebaycid to thilapia, Oreochromis mossambicus (Peters):effects on survival, growth and brain acetylcholinesterase activity(National Science Council:Colombio, 1999) Pathiratne, A.Abstract available from Library, Please quote title when requestingItem Mosquito control(National Science Foundation:Colombo, 2000) Karunaratne, P.Item Novel strategies of insect control:pheromones(Natinal Resources, Energy Science Authority of Sri Lanka:Colombo, 1991) Gunawardene, N.E.Item Freshwater as a natural resource in sri Lanka(NARESA:Colombo; 58p, 1986) Costa, H.H.Item Mosquito control(National Science Foundation of Sri Lanka, 2000-12) Karunaratne, P.
