“…Similar to the rice leaf bug, many species of stink bugs cause pecky rice (e.g., Harper et al, 1993;Jahn et al, 2004;Takeuchi et al, 2004) and invade paddy fields after the heading of rice (Nakasuji, 1973;Rashid et al, 2006). Flowering rice panicle odor also may be attractive to other species of rice-ear bugs and may cause their invasions into paddy fields.…”

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.

We investigated the attractiveness of synthetic volatile blends or individual volatiles of flowering rice panicles or flowering Scirpus juncoides spikelets to the sorghum plant bug Stenotus rubrovittatus (Matsumura). None of the individual chemicals tested attracted either sex of the bug. Synthetic volatile blends of flowering rice panicles composed of geranyl acetone, β‐caryophyllene, n‐decanal, methyl salicylate, β‐elemene and n‐tridecene attracted females. The synthetic blend of volatiles was just as attractive as natural flowering rice panicles to females. Other synthetic blends did not attract the bug. We sampled headspace volatiles from flowering S. juncoides spikelets with solid‐phase microextraction and analysed them using gas chromatography–mass spectrometry. The main volatile emitted from S. juncoides was β‐caryophyllene, one of the major volatile components of flowering rice panicles. β‐Elemene was a common volatile found in flowering rice panicles and flowering S. juncoides spikelets. Therefore, we investigated the attractiveness of synthetic blends of flowering rice panicles and S. juncoides spikelets composed of β‐caryophyllene and β‐elemene. The synthetic blend of flowering S. juncoides spikelets significantly attracted males but not females. The synthetic blend of flowering rice panicles composed of β‐caryophyllene and β‐elemene did not attract either sex. These results suggest that β‐caryophyllene and β‐elemene are common active compounds responsible for attractiveness of flowering rice panicles and S. juncoides spikelets although some of the other volatile components act synergistically with these two compounds in natural plant odours.

“…These two types of stinkbugs live in the furrow agricultural field. They have darts to suck at unhulled rice grains (Ishimoto, 2007, Takeuchi et al, 2004. At the Post-harvest time, raw unhulled rice was stored in the desiccators to keep the harvest time moisture at the level of 13-38%.…”

The purpose of this study is to detect damaged rice grains, which are unhulled and internally damaged by stinkbugs, using an image processing system. The experimental apparatus mainly consists of a multi-spectral camera, fiber-optic light sources, plane-emission light sources, sample plate and personal computer. More specifically, the transmitted light images of 50 grains on the sample plate were generated when the grains were illuminated from the back of the sample plate. Furthermore, while the sample plate was fixed, the light sources were changed over to the fiber-optic light sources irradiating the grains equally from four corners on the upper side of the sample plate. In succession, the raw grains were hulled and visually confirmed to see if any damage had been caused by stinkbugs. The images were processed in the methods using binary conversion processing, contraction processing and mask operation. In this regard, the mean gray level of each normal grain and the number of pixels within the damaged parts of grains were obtained to draw a scatter chart from which the linear discriminant function was derived. As a result, the undamaged grains and stinkbug-damaged grains were discriminated from each other. It was found that the total discrimination rate was 94.6 percent. In conclusion, the possibility of detecting stinkbug-damaged grains using raw unhulled grains can be suggested when the image processing algorithm constructed during this research comes into use.
