The occurrence of Psylla evodiae Miyatake, which has been known to occur on Euodia meliifolia (Rutaceae) in the Yaeyama Islands of Japan and in Taiwan, has been newly recorded in Kyushu (Fukuoka, Nagasaki, and Kagoshima prefectures) and on Yakushima Island and Okinawa Island in southwestern Japan. In addition, it has been confirmed that P. evodiae feeds on Murraya paniculata (Rutaceae), which is a newly recorded host plant in southern Kyushu (Kagoshima Prefecture) and Yakushima Island. It has also been confirmed that P. evodiae feeds on Zanthoxylum beecheyanum var. alatum (Rutaceae) in Okinawa Island.

Triops longicaudatus, a small aquatic crustacean inhabiting the paddy fields of Japan, has eggs that can undergo diapause and survive under dry conditions for several decades. In this study, diapause eggs were embedded in resin and thin sections were observed under light microscopy. Observations revealed that there were abundant yolk granules, or many nuclei, in a diapause egg. Diapause eggs, post-diapause eggs and eggs just after oviposition were homogenized in their groups and the residual material was removed by centrifugation. The samples were analyzed for proteins using two-dimensional gel electrophoresis (2D-GE). The protein spots were visualized by silver staining, and revealed that there were more than 1,400 spots in a diapause egg, and two protein spots (26 kDa, 4.7 isoelectric point) appeared specifically in diapause eggs. It is suggested that these proteins have some relationship with long diapause. The proteins differ from a small heat-shock/α-crystallinprotein (p26) of Artemia franciscana.

The leaf beetle Ophraella communa is an oligophagous insect that infests several asteraceous plants, especially ragweed Ambrosia artemisiifolia, in fields of Japan. The feeding responses of O. communa to methanolic extracts of 11 genera and 17 species of asteraceous plants were examined to determine whether feeding preference depended on chemicals in the plants. The methanolic extracts of 8 asteraceous species stimulated feeding in O. communa, but the other 9 species showed no activity. Two triterpenoids (α-amyrin acetate and β-amyrin acetate) and two caffeic acid derivatives (chlorogenic acid and 3,5-dicaffeoylquinic acid) are known as feeding stimulants for O. communa. The distribution of these compounds was analyzed in 17 asteraceous species. These compounds were found in many species, including nonhost plants of this beetle, however amounts and compositions differed. Even when the methanolic extracts of A. artemisiifolia were added to extracts of some species which did not elicit feeding of O. communa, the feeding of O. communa was not induced by the inactive plants. Feeding deterrents as well as feeding stimulants in the leaves of asteraceous plants appear to determine the feeding preference of O. communa.
