Effect of Rice Volatiles on the Orientation Behavior of the Striped Stem Borer, Chilo suppressalis Larvae

引用

Rice Science 2004年第Z1期 305-308页

作者： CHEN Hua-cai, LOU Yong-gen , CHENG Jia-an , SHEN Qun-chao (Institute of Applied Entomology, Zhejiang university, Hangzhou 310029, china E-mail: huacaichen@*** College of Life. Sciences, china jiliang university, Hangzhou 310018, china)

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.
