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.

导致稻穗虫入侵稻田的水稻植株挥发物的组成在一天内发生变化，并随着水稻发育而变化。虽然三翅目昆虫和红腹狭口线虫都是昼夜活动的昆虫，但前者在光相比暗相更活跃，后者在暗相比光相更活跃。因此，稻纵卷叶蝉入侵稻田可能受稻谷挥发性成分的日变化和稻纵卷叶蝉的昼夜侵染活动的影响。此外，人们还认为虫子取食行为的每一步都受到几种大米化合物的调节。因此，对稻纵卷叶蝉侵染行为中的活性物质进行调控，可以达到预防稻纵卷叶蝉侵染的目的。
