The wood-boring Japanese cedar long-horned beetle, Callidiellum rufipenne, was detected in trap sites in Atlantic, Burlington Camden, Gloucester, and Monmouth Counties last month, NJDA officials confirmed today. The beetle was first detected in the eastern United States in 1997 in North Carolina and in Connecticut in 1998 prompting state and federal agencies to search for the pest in the Garden State this year. During the month of April, under the federally-sponsored Cooperative Agricultural Pest Survey program (CAPS), staff from NJDA's Division of Plant Industry and USDA's Animal and Plant Health Inspection Service/Plant Protection and Quarantine (APHIS/PPQ) conducted surveys at ten sites in six New Jersey counties. The sites were selected at the beginning of the year and included a fence company, cedar mills, a nursery and natural stands of Eastern red cedar. The beetle was subsequently found at six of ten sites. The two sites in Ocean County, both natural stands of Eastern red cedar, have not yet produced positive finds but monitoring will continue every two weeks at least through May. There is currently no approved chemical control for the pest, leaving elimination of the infested tree as the only means of eradication. NJDA's control efforts will focus on infested nursery stock, which, according to state law, must be free of plant pests as a condition of certification and sale. To assist in this effort, NJDA has alerted growers and shippers of nursery stock to the presence of the pest and its nursery inspection staff will include the beetle in its list of pests to watch for.
