Insect Management Considerations in Hemp Production

The Hemp Insect Website is designed to provide hemp producers a way to recognize and to better understand the insects, mites, and other “bugs” that are present when this crop is grown in North America.

The goals of the Hemp Insect Website are to:

(1) Provide description of all insects and mites observed in production of hemp;

(2) Provide information on the habits of all insects that are associated with hemp production.

At present the Hemp Insect Website does give particular attention to insects and mites that are present within the High Plains/Rocky Mountain area of the western United States.  This is because, to date, the most extensive surveys of hemp insects have occurred in this region, mostly in Colorado from 2015 to the present.  However, the goal of this website is to provide progressively more comprehensive treatment of insects associated with hemp production throughout North America.  Submission of photos and inquiries about insects observed on hemp is encouraged from anywhere and the website should expand as the field of hemp insect pest management develops in the United States and Canada.

Note: This website is limited to insect issues involving hemp, defined as Cannabis grown for seed, fiber, or non-THC pharmaceutical products.  This is not a forum for marijuana. Industrial hemp means a plant of the genus Cannabis and any part of the plant, whether growing or not, containing a delta-9 tetrahydrocannabinol (THC) concentration of no more than three-tenths of one percent (0.3%) on a dry weight basis.

Please send in your hemp insect pictures!
