Brown planthopper Nilaparvata lugens, which can transmit rice ragged stunt virus, is a seri-ous and damaging pest to rice plants. Rice plants can protect themselves from the associated diseases of N.lugens by either suppressing or replacing N.lugens by releasing N.lugens infected by a special strain of Wolbachia wStri. The long-distance migration habit of N.lugens is one of the important precursors leading up to the large-scale occurrence of N.lugens. To study the effect of migration on the trans-mission of Wolbachia in N.lugens, a Wolbachia spreading dynamics model with migration of N.lugens ...
