Notes from Conference Call about Current Q-Biotype Whitefly Research on Ornamental Crops

The following laboratories have agreed to receive whitefly samples and determine biotype. The results belong to the sender if they are not paid for with public funds (see Q Biotype Surveillance June 18, 2005) We would, however, like to request that the following information be available to the Whitefly Taskforce:
• Date collected
• Crop:
     > ornamental greenhouse
     > vegetable greenhouse
     > ornamental outside or open structure
     > cotton
     > vegetable
• Location: at the very least we would like State and county.
• Control history if possible:
     > pesticides used
     > control or failure

There are a number of specifics concerning how one collects a sample and preserves it for evaluation. For these specifics, scheduling and pricing information you MUST contact the individual laboratories.
