Abstract:The rice leaf
folder, Cnaphalocrocis medinalis (Guenée), is a destructive insect pest of rice that seriously damages yield and
quality. Understanding the relationship between host plants and the occurrence
of this pest could improve its prevention and management. This paper reviews
previous reports on host plant species, host selection, and the effects of
these on the rice leaf folder, summarizes the relationship between rice
varieties, rice cropping systems and the occurrence of this pest, and discusses
the influence of abiotic factors on these relationships. Research perspectives
on the relationship between host plants and the occurrence of the rice leaf
folder, and the amount of crop damage caused by this pest, are provided. This
review promotes further research on the interactions between the rice leaf
folder and host plants, and on the environmentally friendly management of this
pest.
