Origin of Introductions Regulatory officials need to know the
origin of the ALB infestations to be able to prevent further
introductions from the same sources and to understand the spread
of existing infestations. Also, there are some biological
differences between the populations that may require slightly
different eradication methods used so knowing the origin will be
critical. Developing molecular methods to identify the origins
of North American infestations of ALB. Several different DNA
marker types will be used. Origins of infestations will be
identified. The mtDNA haplotype of beetles from Carteret, NJ
differed from that of New York City/Jersey City beetles by 18
nucleotide sites, from that of Toronto beetles by 17 nucleotide
sites, and from the Chicago/New York City mtDNA haplotype by 4
nucleotide sites. Ranking them in terms of genetic distance from
the New York City/Jersey City, population, we have the
Chicago/New York City mtDNA haplotype most similar (4 different
nucleotide sites) followed by the
