Identifying the molecular markers for complex quantitative traits in natural populations promises to provide novel insight into genetic mechanisms of adaptation and to aid in forecasting population dynamics. In this study, we investigated single nucleotide polymorphisms ( SNP s) using candidate gene approach from high‐ and low‐fecundity populations of the brown planthopper ( BPH ) Nilaparvata lugens Stål (Hemiptera: Delphacida...
