Relative toxicity of technical and commercial formulations of malathion and endosulfan were evaluated by determining LC50 values and their 95% confidence interval end points for 24, 48, 72, and 96 hr exposure to Channa punctatus using the "trimmed Spearman-Karber method." The commercial formulations of malathion and endosulfan were 1.176 and 1.88 times more toxic than their technical materials, respectively. Ninety-six-hour LC50 values (0% trimming) of technical and commercial formulations of malathion and endosulfan (95% confidence interval in parentheses) were 4.51 (4.11-4.96) and 3.89 (3.46-4.38) mg/liter, and 5.78 (4.49-7.44) and 3.07 (2.43-3.84) micrograms/liter, respectively. Fishes showed characteristic changes in behavior when exposed to various concentrations of these insecticides.
