Frequently Asked Questions
What's in the database?
The database is a compilitation of arthropods species (insects, spiders and mites), the pesticides that they are resistant to, when and where in the world the resistance was documented, and a citation of the research paper that documents this resistance.
Where did the information about arthropod resistance come from?
The data is based upon a review of the literature. We obtained resistance data from two primary sources: a previous review by Georghiou G.P. and A. Lagunes-Tejeda (UN FAO, 1991) and our own literature review.
If I see a chemical on the list, does that mean resistance is a problem on my farm?
Not necessarily. These cases are documented for a single species of pest (or non pest) in a specific region in the world, and in some cases many years ago. Not all resistant populations are stable (meaning resistance in a pest population can decline when the pesticide is not applied for awhile). In some cases, a pesticide resistant pest population was developed in the lab only.
When was the last update of the database?
The database is updated regularly.
What additional information about pesticide resistance is there? I only see lists of species and chemicals?
Our current focus is on the timeline of resistance development. The database includes only documentation of the first occurence of resistance to a pesticide by a population within a geographic region. Of course, our long-term goal is to build upon this base and incorporate more information such as details of the bioassay, resistance ratios, cross-resistance, mechanisms, etc.
I know of a case (or two) that I don't see in your database. Can it be incorporated?
No literature review is complete, and new cases occur every year. We encourage researchers to please use the Online Resistance Survey to submit this information.

Who funded this project?
This database was made possible by grants from the US Department of Agriculture,CSREES Pest Management Alternatives Program, the Insecticide Resistance Action Committee (IRAC), and Generating Research and Extension to meet Economic and Environmental Needs (GREEEN) Project # GR02-69, Michigan Agricultural Experiment Station (MAES), Michigan State University Extension (MSUE) and the Michigan Department of Agriculture (MDA).
