Correlation between colorimetric and protein-precipitation assays of tannins dissolved in treehole water.
There was a significant correlation between colorimetric and protein-precipitation assays of tannins dissolved in treehole water. The protein-precipitation potential of early-season treehole water was extremely low relative to total phenolics measured by colorimetry. The protein-precipitation method is recommended because it directly measures protein binding, the property of dissolved tannins relevant to mosquito development. Furthermore, the procedure is not affected by treehole water color and does not produce dangerous wastes.
