Development of Microsatellite Markers for the Nipa Palm Hispid Beetle, Octodonta nipae (Maulik)‎

Abstract EN

The nipa palm hispid beetle, Octodonta nipae (Maulik) (Coleoptera: Chrysomelidae), is an important invasive pest on palm plants in southern China.

Based on existing transcriptome data, polymorphism simple sequence repeat (SSR) loci were identified.

In total, 1274 SSR loci were identified from 49919 unigenes.

The majority of them contained mononucleotide, dinucleotide, and trinucleotide motifs (43.56%, 26.14%, and 28.18%), in which A/T (41.21%) and AT/TA (15.86%) were the most abundant motifs.

104 pairs of the SSR primers produced amplification bands of expected sizes in O.

nipae, 80 pairs of SSR primers were tested randomly for polymorphism, 9 loci of them were validated to be polymorphic markers, and the number of alleles ranged from 2 to 3, with an average of 2.56 per locus.

The population of Zhangzhou and Fuzhou was analyzed by the 9 loci (On1–On9).

These SSR transcriptome data can provide invaluable resource for SSR development, population genetics research, invasion and expansion mechanism, paternity testing, and other research on O.

nipae and its related species.
