Resistance of insects to control chemicals poses a major problem in crop, food and health protection. WHO has contributed greatly to our understanding of this problem by establishing simple, standardized and reliable techniques for assessing the susceptibility levels of populations of insects of world health importance to current chemical controls. Only by having an extensive record of such levels, at both different times and places, can changes or trends e.g., developing resistance, be detected. Lack of such standardized techniques makes it difficult to ascertain whether control failures are a result of poor application methods or increasing resistance.
