Agricultural agencies in the United States have been charged with a mission of preventing exotic pest infestations. This mission protects agriculture, the environment and our citizens from the damaging effects of plant pests. Accomplishment of this mission and satisfying the need for equitable trade is a major challenge. For almost four decades, Diaprepes root weevil has presented major challenges for Florida agriculture. From the early attempts to eradicate to present nursery quarantines, Diaprepes root weevil is a daunting and long term pest of many agronomic crops grown in Florida and the United States. Today, part of preventing the long distance spread of Diaprepes root weevil and a basic strategy used in regulatory pest control is the restriction of movement of known infested host plants.
Diaprepes root weevil is a polyphagus feeder (Simpson et. al., 1996) and has the potential to be a major pest to Florida's 6.11 billion dollar agricultural industry (Table 1). The 1998 cash value of Florida crops that are known hosts of Diaprepes is 4.2 billion dollars (Table 1). Presently, Diaprepes abbreviatus infests approximately 140,000 acres in twenty-two Florida counties. The Florida Department of Agriculture and Consumer Services, Division of Plant Industry has conducted regulatory actions for this pest since the first Diaprepes root weevil detection in Florida in 1964. The first detected weevil was an adult female collected on the foliage of a citrus tree growing in a small citrus nursery located in northwest Orange county. The regulatory process began at this point and continues today. Presently, the regulatory process restricts the movement of all plants where any life stage of the Diaprepes root weevil is detected.
In 1968 large numbers of adult and larval Diaprepes were detected and efforts were directed to quarantine and eradication of this imported and exotic pest (FDACS, 1968-1970). In 1968 approximately 5000 acres (3500 acres of citrus) were quarantined. In 1974 this quarantine area was extended to 32,640 acres (10,201 acres were citrus). During this period, larval quarantine treatments were aerial applications of granular heptachlor at 3 lb ai/ac, granular chlordane at 5 lb ai/ac with ground applications of dieldrin at 5 lb ai/ac. Adult quarantine treatments consisted of Sevin 80%WP at 10 day to two week intervals during adult emergence periods.
In 1976, eradication efforts were suspended due to the concern of potential environmental problems with the use of the persistent pesticides used for control of Diaprepes root weevil. Control and quarantine programs are still in effect today with major emphasis being directed to the development of control and regulatory procedures for all agronomic crops associated with Diaprepes root weevil. The presence or absence of Diaprepes at any given location is directly dependent on the efficacy of available detection technology. Present detection methods rely upon seeing the adults or a labor intensive larval survey in soil associated with host plants. These surveys are dependent upon the time of year when adults are active or even the physical location in Florida.
Diaprepes root weevil nursery quarantines are authorized by Florida Statutes 581 and Rule 5B-2.0025, Certification and Quarantine of Nursery Stock. This action regulates plant pests of limited distribution in Florida that require immediate action. All nursery stock infested or exposed to Diaprepes root weevil is quarantined and will not be eligible for certification until required treatments are conducted. A Diaprepes Compliance Agreement is established with the grower that prescribes regulatory treatment procedures or actions that must be complied with. Treatments are for adult, larva and egg control. If any life form of a Diaprepes root weevil is detected in a nursery, the nursery is quarantined. Presently, there are 179 nurseries located in 11 counties that are quarantined for the presence of Diaprepes. If a prospective buyer is interested in purchasing plants from a nursery and has concerns about Diaprepes existing in the nursery, the Diaprepes status of the nursery is available by contacting the Division of Plant Industry in Gainesville, Florida.
For regulatory purposes, host plants can be defined as plants suitable for support of any stage of the life cycle. The 293 host plants, listed in Table 2, have been observed supporting at least one stage of the life cycle of Diaprepes root weevil. Numerous host plants are considered tropical and are planted in exterior landscapes of South Florida and the Caribbean. These same plants are also used in interior landscapes for shopping malls, businesses, and residents throughout Florida. Dracena (Dracena marginata Lam.), a native of West Africa that has multiple slender stems with colorful clustered sword-shaped leaves, is planted as an exterior shrub in South Florida and also has numerous interior landscape uses, e.g., doctors' and dentists' offices. This plant supports all life stages of the Diaprepes root weevil.
Without adequate and reliable attractants, regulatory detection of Diaprepes is dependent upon host plant surveys. Previous attempts at development of traps and attractants for this weevil are not considered sufficient to recommend as a survey technique for regulatory purposes (Bevers et al., 1979; Schroeder and Jones,1983; Schroeder and Jones,1984). Host plants provide a source of needed sustenance, cover and concealment from predators, and locations for the female to deposit eggs. These basic behavioral characteristics which the host plant provides, enables us to visually detect the presence of adults and other life stages.
Genetic studies of nine geographically distant Florida populations indicate that D. abbreviatus has generally remained in the locality of their original introduction and have limited dispersal to new areas (Bas et al., 2000). The most likely means of spread of D. abbreviatus is on infected plant material. Adults are strong fliers but have been observed to fly relatively short distances. It should come as no surprise that Diaprepes root weevil is difficult to regulate. When an insect has almost 300 hosts (Table 2), many of which occur or are grown in Florida the regulatory picture is murky indeed. For instance pigeon pea is found in many of Florida's agriculture regions. Add all of the citrus varieties, holly, chinaberry, banana, avocado, various beans, a few palms, wax myrtle, guava, and a castor bean. These form a formidable list of life cycle hosts and partial life cycle hosts which occur in the wild and as ornamentals.
The regulatory process basically restricts the movement of host plants or plant parts which contain any life stage of Diaprepes root weevils.
