To protect Procapra praprzewalskii appointed as CR (Critically Endangered), twenty pairs of microsatellite primers from Granti s gazelle and sheep separately were used to screen microsatellite locus in faecal DNA from Procapra praprzewalskii, eight polymorphism loci was found.

Microsatellites or simple repeat sequence have already demonstrated to be a powerful tool in recent years.

The PCR technique with microsatellite primers was used to analyze the DNA polymorphism in different forms (mother of mating forms, mating female, male, fundatrix, apterous and alate virginoparae ) of the cotton aphid, Aphis gossypii.

The study examined the genomic DNA extraction from the 5 scale insect species and the polymorphisms PCR of the 5 species using the microsatellite primers.

Preliminary study on applicability of microsatellite primers developed from Crassostrea gigas to genomic analysis of Hyriopsis cumingii;

Microsatellite primer-PCR was used to analyse the DNA polymorphism of two body colour bio-types (red bio-type and green bio-type) of green peach aphid from the three kinds of different host plants which are tobacco (Nicotiana tabacum L), rape (Brassicue compestris L.

In order to determine the applicability of microsatellite primers developed from common carp (Cyprinus carpio) for genomic analysis in grass carp (Ctenopharyngodon idellus), twentyeight pairs of common carp primers designed for microsatellites containing CA motifs were employed to amplify the microsatellite loci in the genome of grass carp.

Random Microsatellite Amplified Polymorphic DNA (RMAPD) markers were used to measure genetic diversity and genetic structure of 245 individuals from12 natural populations of Pinus tabulaeformis Carr.
