“…mtDNA analysis has revealed vast amounts of information about intra-and interpopulation genetic diversity and gene flow (Avise et a!., 1987). The approach has been instrumental in revealing diver-sity in such animals as grasshoppers (Chapco et at., 1992), deer mice (Lansman et at., 1983), island fox (Wayne et al, 1991) and rhinoceroses (O'Ryan & Harley, 1993). Population data on insect pests other than Listronotus, such as the screwworm fly (Roehrdanz & Johnson, 1988;Roehrdanz, 1989), boll weevil (Roehrdanz & North, 1992) and mosquito (Kambhampati & Rai, 1991), have been obtained using mtDNA analysis.…”
