The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae), is a notorious pest in rice production. microbial secondary metabolite, decoyinine (DCY), produced by Streptomyces hygroscopicus. Recent studies found that seed priming with DCY could enhance resistance to BPH and Laodelphax striatellus; however, the mechanism of enhancing insect remains unclear. Here, an integrate...
