Abstract:

The orientation behavior of the 1st and the 3rd instar larvae of the striped stem borer (SSB), Chilo suppessalis, to the volatiles emitted from rice plants was studied with a Y-tube olfactometer. The treatments included healthy plants vs clean air (HP vs CA), striped stem borer damaged plants vs clean air (SSB-DP vs CA), rice leaf folder damaged plants vs clean air (RLF-DP vs CA), HP vs SSB-DP, HP vs RLF-DP and SSB-DP vs RLF-DP. Volatiles from all rice plants had significant attraction for both of the 1st and the 3rd instar larvae. The orientation selection of larvae to the volatiles from rice plants treated differentially (HP, SSB-DP, and RLF-DP) did not impose any significant influence.

Key words: rice, volatile, Chilo suppressalis, larvae, orientation behavior
