Item Effect of azadirachtin on growth and the activity of midgut enzymes of the cockroach periplaneta americana(National Science Foundation:Colombo, 2001) Paranagama, P.A.; Kodikara, K.A.B.C.H.; Nishantha, H.M.I.; Mubarak, A.M.Item A procedure for sterilising leaf explants collected from wild neem (Azadirachta indica) trees(National Science Council:Colombo, 1999) Eeswara, J.P.; Allan, E.J.; Mordue, A.J.; Stuchbury, T.Experiments conduted to find suitable sterilisation procedures for neem explants collected from trees growing in the wild showed that they could not be sterilised by the method for leaves collected from the trees reared in the laboratory (10perc. 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 azadirachtin on incorporation of 35S-cysteine into peptides in the brain and corpus cardiacum in the locust Schistocerca gregaria(National Science Foundation:Colombo, 2003) Paranagama, P.A.; Connolly, J.D.; Strang, R.H.C.Item Systemic effects of neemazal-T/S on the rice brown planthopper, Nilaparvata lugens (Stal)(National Science Foundation:Colombo, 2006) Manatunga, P.N.N.K.; Karunaratne, M.M.S.C.Item Effects of shade and water stress on growth and related physiological parameters of the seedlings of five forest tree species(National Science Foundation:Colombo, 2000) De Costa, W.A.J.M.; Rozana, M.F.Item Evaluation of volatile constituents of neem (Azadirachta Indica A. Juss.) leaf extracts against Callosobruchus maculatus (F)(National Science Foundation:Colombo, 2003) Paranagama, P.A.; Adhikari, A.A.C.K.; Abeywickrama, K.P.; Bandara, K.A.N.P.Item Azadirachtin effects on proteins synthesized in fat body, haemolymph, ovary and mid-gut of locusts, Schistocerca gregaria(National Science Foundation:Colombo, 2004) Paranagama, P.A.; Connolly, J.D.; Strang, R.H.C.
