Mitochondrial DNA Variation of The Rice Yellow Stem Borer, Scirpophaga Incertulas (Lepidoptera: Crambidae) in Java, Indonesia

Scirpophaga incertulas is an economically important rice pest. A systematic investigation on the biological characteristics of ecological races linked to recent changes of agricultural practices and the environment has been conducted in order to assess genetic variation of S. incertulas in Indonesia. A 685bp segment of mitochondrial DNA, COII, was amplified from 42 yellow stem borer samples from five locations in Java (Madiun, Ngawi, Wonogiri, Tasikmalaya, and Indramayu). Six different haplotypes (YSB1, YSB2, YSB3, YSB4, YSB5 and YSB6) were identified in the sequenced yellow stem borer populations, with haplotype YSB2 being dominant. Treubia, Vol. 42.
