The toxicity of oil extract of Tetrapleura tetraptera on tadpoles was investigated. Concentrations 0.4ml/L,
0.8ml/L, 1.2ml/L and 1.6ml/L of the oil extract were prepared using untreated water. The tadpoles were
introduced into the various concentrations and observations were made at intervals over 24 hour period. The
assay was conducted in three replicates. Results showed that T. tetraptera was highly toxic to tadpoles with
LC50 of 0.189ml/L at 24 hours. From the result, there was clear indication that T. tetraptera, though a
potential molluscicide, is also a potential poison to some other water fauna that make up the aquatic
ecosystem.
