Abstract:
[Objectives] To provide a convenient and efficient
way of identifying Anagrus dmitrievi Triapitsyn
& Hu, a small parasitic wasp with potential as a biological control for the
corn pest Zyginidia eremita Zachvatkin
(Hemiptera, Cicadellidae, Typhlocybinae), that is difficult to identify on the
basis of morphological features. [Methods] Eggs of Z.
eremita were collected and hatched in a laboratory to obtain adult A. dmitrievi which were then identified
according to morphological characters such as body color, antennae and wings.
Genomic DNA was extracted from the adult wasps using a non-damaging DNA
extraction method, and DNA barcoding tests performed on the COⅠ and ITS2 genes after PCR amplification and sequencing. [Results] Multiple sequence alignments, genetic
distance and phylogenetic analyses indicate that although A. dmitrievi COⅠ and ITS2 are highly homologous to those of other Anagrus species
listed in the NCBI databases, there are some clearly distinguishable
differences. [Conclusion] COⅠ and ITS2 gene sequences were obtained from
male and female A. dmitrievi are sufficiently distinctive to provide a
foundation for the development of a molecular rapid identification system for
this small, parasitic wasp.
