APRD Survey

Dear Users:

We value your contribution to and use of the Arthropod Pesticide Resistance Database (APRD).

The APRD Team is conducting a Survey to gauge users experiences, our objective is to determine how the database enhances research, and to allow for users to provide feedback, suggestions and requests for potential improvements. Please take the anonymous survey using this link: Link to Survey

Thank you for your Participation,
David Mota-Sanchez
