    Irrigation water can act as a vector, or carrier, that can transport or spread pathogens to crops, where they have the potential to cause illness (CDC, 2018). Decisions to treat irrigation water can be driven by buyer requirements, for product marketing or branding, or because the water quality exceeds the FDA Food Safety Modernization Act (FSMA) regulations or the Leafy Green Marketing Agreement (LGMA) standards for generic Escherichia coli (E. coli).

    Arizona Kissing Bugs
    Publication (PDF, 1.3MB)
    Authors: Shujuan Li, Dawn H. Gouge, Shakunthala Nair, Alfred J. Fournier, and W. Eugene Hall
    Kissing bugs are true bugs in the insect Order Hemiptera, in the Family Reduviidae. Reduviids as a family, are sometimes called assassin bugs because most members of this family are predators of other arthropods and are in fact beneficial to humans. Kissing bugs are an exception, and are blood-feeding parasites that feed on a wide variety of domestic, wild animals, and occasionally humans. Kissing bugs are also known as conenose bugs, Triatomine bugs, Mexican bed bugs, and Wallapai tigers. Kissing bugs get their name because they often bite sleeping human victims on the face. Although kissing bugs are in the same insect order as bed bugs and both feed on blood, they have different life histories.
