During tsetse control operations it may be necessary to determine the effective toxicity and persistence of insecticide residues on vegetation. A simple method for preparing samples of twig bark for bioassay and an exposure apparatus that has been found very satisfactory for exposing tsetse flies to residues on leaves and bark are described. The apparatus is easily manipulated and involves little handling of the test material.
在采采蝇防治行动中，可能有必要确定杀虫剂残留在植被上的有效毒性和持久性。本文描述了一种制备用于生物测定的嫩枝树皮样本的简单方法，以及一种用于让采采蝇接触树叶和树皮上残留物质的暴露装置，该装置已被证明非常令人满意。该装置易于操作，且对测试材料的处理较少。
