Hyalella azteca are invertebrates that are widely used for sediment and water toxicity studies. Investigators have found that H. azteca collected from sites influenced by agricultural/urban runoff are as much as 2-times less sensitive to pyrethroid insecticides than lab-grown H. azteca. In contrast, the insecticide sensitivities of H. azteca collected from undeveloped sites beyond the influences of agricultural/urban runoff were similar to those of lab-grown populations.
