The determination of the impurity chrysotile in talc was developed for routine assays [41]. The test is based on the adsorption of bromocresol blue by chrysotile. Since talc will not absorb the dye, the final measurement is a spectrophotometric determination of the dye left in solution after adsorption.

With sucking insects that produce honeydew, the amount of honeydew excreted is assumed to be proportional to feeding. Honeydew production can be measured as number of droplets (using bromocresol blue or ninhydrin as a stain Auclair 1958), or the stained honeydew can be collected, extracted from the collection chamber, and measured colorimetrically (Nisbet et al. 1994). Several problems must be addressed with the use of honeydew as an index of consumption. First, some aphids will produce nymphs when feeding on artificial diet, and the production of honeydew by nymphs may inflate the quantity recorded for the test insect. The simplest solution here is to frequently remove any nymphs that are produced. Second, because aphids may scatter their honeydew, the droplets will not always fall directly below the aphid. Thus, collection dishes must be sufficiently large to collect all of the honeydew that might be produced. Alternatively, the entire chamber must be lined with material used to collect the honeydew, from which it is extracted subsequently (e.g., Nisbet et al. 1994).
