With the advent of next‐generation R oche 454 pyrosequencing technologies, transcriptome level sequence collections are arising as prominent resources for the discovery of gene‐based molecular markers. In a previous study more than 1450 simple sequence repeats ( SSR s) in expressed sequence tag ( EST ) sequences resulting from 454 pyrosequencing of L aodelphax striatellus c DNA were identified. From these we developed PCR primers for 40 di‐ or tri‐candidate SSR s (minimum repeats > 8) from the combined EST library. After extensive optimization, 13 pairs were end labeled with a fluorescent dye. Here, we also tested these 13 SSR s for cross‐species amplification in two other planthoppers, N ilaparvata lugens and S ogatella furcifera . The marker transferability was considerably high in N . lugens (92.31%) and in S . furcifera (61.54%). All of the 13 fluorescent SSR s were polymorphic, with allele numbers ranging from two to seven for 24 male and 24 female L . striatellus individuals. Observed heterozygosities ranged from 0.016 to 0.621. Development of SSR markers from EST s will be a valuable tool to improve our understanding of population structure in this important rice pest.
