However, little is known about its biological function in invertebrates. Here, we identified 12 members of histone deacetylases (NlHDACs) in the brown planthopper (BPH), <i>Nilaparvata lugens</i>. RNAi-mediated silencing assay showed that the <i>NlHdac1</i>, <i>NlHdac3</i> and <i>NlHdac4</i> played critical roles in female fertility via regulating ovary maturation or ovipositor development. Silencing of <i>NlHdac1</i> substantially increased acetylation level of histones H3 and H4 in ovaries, indicating NlHDAC1 is the main histone deacetylase in ovaries of BPH. RNA sequencing (RNA-seq) analysis showed that knockdown of <i>NlHdac1</i> impaired ovary development via multiple signalling pathways including the TOR pathway. Acoustic recording showed that males with <i>NlHdac1</i> knockdown failed to make courtship songs, and thus were unacceptable to wild-type females, resulting in unfertilized eggs. Competition mating assay showed that wild-type females overwhelmingly preferred to mate with control males over <i>NlHdac1</i>-knockdown. These findings improve our understanding of reproductive strategies controlled by HDACs in insects and provide a potential target for pest control. histone deacetylase;planthopper;fertility;courtship song 2018-11-22
