Aphid Species Identification

Date: February 2, 2018

"The knowledge of aphids on Cannabis may be quite incomplete.  Knowing more ... would be interesting and potentially useful to pest management practitioners." - Andy Jensen, Ph. D.

Pest management can be a huge challenge but proper practice is crucial to the health and profitability of a crop. Identifying which species of aphids cultivators are dealing with is very important in order to come up with an effective treatment/prevention plan -- Especially recently, with species never before found on cannabis beginning to appear in crops across the nation.

Andy Jensen, Ph. D., one of the foremost aphid identification experts in the U.S. has expressed great interest in aphids from Cannabis after recently receiving a sample from a producer in California of a species that has never previously been recorded on Cannabis. Jensen, who completed his dissertation in aphid systematics, believes that "the knowledge of aphids on Cannabis may be quite incomplete.  Knowing more about aphids on Cannabis would be interesting and potentially useful to pest management practitioners."

The Cannabis Alliance has been offered Jensen's expertise and he is willing to accept and identify aphid samples from cultivators here in Washington. If you are interested in sending in an aphid sample please email us for shipment instructions. info@thecannabisalliance.us

NOTE: Aphids should ideally be sent by UPS ground, in vials or very small jars, and preserved in alcohol.  Isopropyl (rubbing) alcohol, or ethanol are both acceptable.  It is crucial to receive adult specimens, so collectors should carefully find and collect only the very largest specimens on their plants.  Information about the collection is also useful, such as state and county collected, and whether the plants were indoors, in a greenhouse, or outdoors.
