It has been well documented that plants in response to herbivory release specific volatiles to attract natural enemies of herbivores and/or repel herbivores.And several field studies have shown that these herbivore-induced volatiles enhance the parasitism or predation of herbivores.Thus, it may decrease the damage of the herbivores by manipulating or applying these volatiles.Using rice plants, rice brown planthopper (BPH) Nilaparvata lugens (St(a)l) and its parasitoid Anagrus nilaparvatae Peng et Wang as a model system, induced rice indirect defense and its perspective for application were studied.The results showed that A.nilaparvatae was attracted to volatiles released from rice plants infested by N.lugens or treated by jasmonic acid (JA).JA-treated rice plants also enhanced parasitism of N.lugens eggs in the greenhouse and field.
