Funding for this Project will be used to study two critical areas of uncertainty related to the role of insecticides in Delta Smelt population declines. First, it investigates the role of storm driven contaminant loading on larval Delta Smelt development and behavior, linking recent data obtained from laboratory exposure to single insecticide compounds, to the realistic environmental conditions the developing fish experience. Secondly, it explores how insecticides have shaped invertebrate communities in the Delta through the evolution of insecticide resistance.

The Project objectives are to:
1. Determine neurodevelopmental and behavioral impacts of contaminated water samples on larval Delta Smelt associated with rain events in the Cache Slough complex in the North Delta.
2. Characterize the extent of adaptive resistance within invertebrate communities of the Cache Slough complex and correlate the occurrence of resistance with the abundance of specific taxa and insecticide body burden concentrations in these prey items.
