The pink hibiscus mealybug, Maconellicoccus hirsutus (Green), became a
serious economic threat to US Agriculture when it first appeared in the
Western Hemisphere in Grenada in 1994. Since then it has spread to over 30
Caribbean Islands, plus Southern California and Belize (Central America) in
1999, the Bahamas in 2000, and Florida, Dominican Republic and Haiti in
2002. This mealybug attacks over 200 plant species in 75 different plant
families including fruit trees, vegetables and ornamentals. In
safeguarding American agriculture, a preemptive action was taken by the US
Department of Agriculture, Animal and Plant Health Inspection Service,
Plant Protection and Quarantine and International Services in order to
develop a biological control technology, which would be a self-sustaining
control program. The program success has resulted in as much as 97%
reduction of the mealybug's population density within a one year period
after being applied to the US Territories in the Caribbean, Belize,
California, and the Bahamas, and is presently being implemented in Florida,
Dominican Republic and Haiti. This proactive program bought time to
develop this technology offshore as a cost shared cooperative effort with
neighboring countries and international organizations prior to this
mealybug's entry into the Continental United States. This allowed the
technology to be implemented within thirty days of detecting this pest in
the US minimizing economic losses and reducing the pests dispersal rate.
