    Brazilian Peppertree

    The biological control program for Brazilian peppertree (Schinus terebinthifolia) launched distributions of biological control agents, to control the state's most serious invasive plant. Four candidate biological control agents are currently under study at the UF/IFAS Norman C. Hayslip Biological Control Research and Containment Laboratory:

    1. Pseudophilothrips ichini (Thysanoptera: Phlaeothripidae)
    2. Calophya latiforceps 
    3. Calophya terebinthifolii
    4. Calophya lutea (Hemiptera: Calophyidae)

    Release permits for C. latiforceps and P. ichini were issued in June 2019. Host range testing of the other two agents is complete (manuscript in review). Biological studies for the remaining Calophya spp. will continue once healthy colonies are received from Brazil.

    Invasive Plant Biological Control Program

    Scientists have determined that the best way to control Brazilian peppertree is through biological control. This method eliminates the need for expensive, mechanical control, and toxic chemicals. Brazilian pepper thrips have already been released at parks and private ranches. Researchers have observed that the Brazilian pepper thrips have begun to impact Brazilian peppertrees.

    • Frequently Asked Questions
      • When was Brazilian peppertree introduced to Florida?
        Brazilian peppertree was first introduced into Florida around 1840, and then again around 1890. It was not recognized as a problem in the state until the 1960s.

      • Why was Brazilian peppertree introduced into Florida?
        Brazilian peppertree was introduced as an ornamental because of its prolific production of red fruits during the winter. Other names for Brazilian peppertree are Christmas berry and Florida Holly. As with Brazilian peppertree, the majority of the invasive plants in Florida were introduced as ornamentals.

      • Where did Brazilian peppertree come from?
        The native range of Brazilian peppertree includes Brazil, Paraguay, Argentina, and Uruguay. Two types of Brazilian peppertree were introduced into Florida: one from southeastern Brazil, and a second from the northern coastal area of Brazil. The two types of Brazilian peppertree are now extensively hybridized in the state.

      • Are any biological control agents available for Brazilian peppertree?
        Yes, the Brazilian pepper thrips has already been released at parks and at private ranches. The Brazilian pepper thrips have begun to impact Brazilian peppertrees.

      • What is the best way to control Brazilian peppertree?
        Biological control offers a natural solution with Brazilian peppertree's natural enemies from its native range. Biological control eliminates the need for expensive, mechanical control, and toxic chemicals.

      • Is Brazilian pepper tree harmful to people?
        Some people are quite allergic to Brazilian peppertree. It is in the same plant family as poison ivy and poison oak, and can cause severe skin irritation and breathing problems in some people.

      • How is Brazilian peppertree spread?
        When Brazilian peppertree was still sold as an ornamental, human transport was probably the major method that Brazilian peppertree spread throughout the state. Now that it is no longer sold as an ornamental, birds and small mammals are responsible for most dispersal.

      • Why do I only see fruit on some Brazilian peppertrees, but not others?
        Brazilian peppertree, like many other plants, is dioecious. This means that individual plants are either male or female. Only female trees produce fruits.

      • I’ve heard that birds can become intoxicated by feeding on Brazilian peppertree fruit. Is this true?
        This is difficult to determine, as there is no experimental evidence - only anecdotal observations. Like other plants, Brazilian peppertree fruit contains sugar that can ferment. Fermentation results in the production of alcohol. Thus, it's possible that if a bird ate large quantities of over-ripe Brazilian peppertree fruit, it could conceivably become intoxicated. However, this is not unique to Brazilian peppertree. Fermented fruit from other plants could also contain alcohol, and therefore potentially intoxicate birds and other wildlife.
