| identification of a distinct lineage of cacopsylla chinensis (hemiptera: psyllidae) in japan on the basis of two mitochondrial dna sequences. | psyllids are a menacing pests of pears (pyrus spp.) grown in temperate and subtropical regions of the world, including taiwan and china. pear psyllids belong to the large genus cacopsylla (psyllidae: psyllinae). among the 28 psyllid species that infest pear trees, cacopsylla chinensis (yang and li, 1981) is considered the most harmful. two psyllid outbreaks involving exotic species affected japanese pear (pyrus pyrifolia variety culta) orchards in the saga prefecture in july and november 2011. t ... | 2013 | 23786037 |
| identification of two invasive cacopsylla chinensis (hemiptera: psyllidae) lineages based on two mitochondrial sequences and restriction fragment length polymorphism of cytochrome oxidase i amplicon. | the occurrence of pear decline, a disease found in some pear (pyrus spp.) orchards of taiwan in recent years, is accompanied by an outbreak of cacopsylla chinensis (yang & li). two major morphological forms (summer and winter forms) with a variety of intermediate body color and two phylogenetic lineages of this psyllid have been described. the work herein used sequences of mitochondrial cytochrome oxidase i (coi) and 16s rdna regions to delineate the genetic differentiation of this color-variabl ... | 2008 | 18767723 |
