Extrafloral Nectary Insect Activity on Cover Crops video

See the abundance of insect activity on the extrafloral nectaries growing on cover crops. Extrafloral nectaries are nectar-secreting glands not involved in pollination produced in at least 66 plant families. The “EFNs” grow on their leaves, shoots, or in the case of cowpeas, at the juncture of the pod and the stem. The sugar and mineral rich liquid attracts predators and parasitoids, such as ants and wasps, which in turn defend the plants against herbivores and promote biodiversity of insect populations and pollinators.
