Insects and Mites Associated With Hemp Production
Hemp fields can support a lot of different kinds of insects. Being able to recognize what is present – and also what they may be doing to the crop – is a fundamental interest of any producer.
Some of the insects one will see may be feeding on the plant, either chewing leaves or flowers, boring into seed heads or stems, or sucking fluids from leaves. Also common, and sometimes more visible, are various insects and spiders that feed on other insects, the natural enemies of those that feed on the plant. Hemp may be used as a temporary site for resting and shade by various types of “transient” insects that are locally common and hemp crops that produce pollen can attract enormous numbers of bees and other pollen feeders.
This website seeks to illustrate all of the “bugs” (insects, spiders, mites, etc.) one might encounter in a hemp field, providing a type of diagnostic guide. With this information growers can better understand what they are observing in production of this crop and be able to appropriately respond.
In this start-up form (spring 2017), the Hemp Insect Website has a particular focus on what is known to occur in Colorado, as preliminary surveys have been made in this state in 2015-2016. However, as the goal of this website is to provide progressively more comprehensive treatment of insects associated with hemp production throughout the United States. One way that this is being encouraged is by providing a means to submit images and inquiries of insects that are observed on any US-grown hemp, to do so please see the “Got Bugs?” page.
