| Research Abstract |
Composition of rice plant volatiles which cause invasion of rice-ear bugs into paddy fields changed during a day as well as rice development. Although both Trigonotylus caelestialium and Stenotus rubrovittatus were nocturnal-diurnal insects, the former was more active in the photophase than in the scotophase and the latter was more active in the scotophase than in the photophase. Therefore, invasion of the bugs into paddy fields may be influenced by changes of volatile composition from rice during a day and diurnal infestation activities of the bugs. In addition, it was suggested that each step of feeding behavior of bugs was regulated by several rice compounds. Therefore, regulating active compounds which play roles in infestation behaviors of the bugs may lead to prevent infestation of rice by the bugs.
