Volatiles were extracted from rice plants of various growth stages with solid-phase microextraction (SPME) and analyzed by gas chromatography-mass spectrometry (GC-MS) to identify attractants that cause invasion of the rice leaf bug Trigonotylus caelestialium (Kirkaldy) into paddy fields. The composition of volatile blends produced by rice plants changed with rice development. In addition, volatile blend compositions differed between the panicles and the stems and leaves. The relative geranyl acetone content was high in all plant structures analyzed. In volatiles from whole plants in the fourth-leaf stage and panicles in the full-ripe stage, the relative content of green leaf volatiles (GLVs) was higher than that found in other rice plant structures. In contrast, relative terpene levels emitted from whole plants in the panicle-formation stage and by panicles and stems and leaves in the flowering stage were higher than those of other rice plant structures. However, the type of terpenes found differed between the panicles and the stems and leaves. Relative levels of β-caryophyllene in whole plants in the panicle-formation stage and panicles in the flowering stage were much higher than that in stems and leaves in the flowering stage. Our previous studies demonstrated that the odor from whole plants in the panicle-formation stage and panicles in the flowering stage is attractive to rice leaf bugs. Here, the attractiveness of β-caryophyllene to adult bugs was investigated in olfactometer assays. Adult females were attracted to β-caryophyllene at a concentration of 0.001%, which is approximately equivalent to the concentration produced by flowering rice panicles. However, β-caryophyllene also was present in the odor of whole plants in the fourth-leaf stage and in stems and leaves in the flowering stage. Furthermore, the amounts of this compound emitted from these structures were similar. Therefore, we suggest that the relative abundance of this compound in a volatile blend is important for attractance of the bugs.

“…Initially, they reproduce mainly on gramineous weeds such as P. annua and L. multiflorum. The invasion of adults into rice paddy fields gradually increases with the heading of the rice and rapidly increases with flowering (Okuyama, 1974;Hachiya, 1999;Ishimoto, 2004). Afterwards, the invasion ceases abruptly.…”

The olfactory response of the sorghum plant bug, Stenotus rubrovittatus (Matsumura) (Het., Miridae), to rice, Oryza sativa L., and paddy weed, Scirpus juncoides Roxb. var. ohwianus T. Koyama, was investigated with an olfactometer to clarify the mechanism of the invasion of the bugs in paddy fields. Both adult females and males were significantly attracted to panicles of rice in the flowering and full‐ripe stages. Whole plants (aboveground parts) of rice in the panicle‐formation stage, and stems and leaves of rice in the flowering stage significantly attracted only adult females. Other rice structures tested did not attract males or females. Both males and females were attracted to the flowering spikelets of S. juncoides. Although females showed no olfactory response to stems of S. juncoides in the flowering stage, males were repelled by them. Only females were attracted to whole plants of flowering S. juncoides. Whole plants of S. juncoides in the spikelet‐formation stage significantly attracted only females. The findings suggest that the invasions of S. rubrovittatus into paddy fields are caused by their olfactory responses to the volatiles emitted from rice and some paddy weeds such as S. juncoides.

We exposed non-diapause eggs of the rice leaf bug Trigonotylus caelestialium to a low temperature (4°C) and investigated the effects on hatching, nymphal survival, and developmental periods with a view to obtaining many newly hatched nymphs or newly emerged adults on the same day. When eggs were stored at a constant temperature of 25°C, 54.1% of nymphs and 50.9% of adults emerged on the 7th day and the 20th day after collecting them for 24 h, respectively. The hatching rates of eggs exposed to the low temperature for 7, 10, and 13 day were significantly lower than that of eggs maintained at 25°C. However, compared to the non-exposure group, only a small decrease in the hatching rate was observed in the 4-d exposure group (8.1%). Further, exposing the eggs to the low temperature did not affect the survival of the nymphs to adult emergence or the developmental periods. These results suggest that the exposure of eggs to the low temperature for 4 d or less should be a simple and useful method for obtaining many nymphs and adults on the same day.
