甲虫目を初めとする折りたたみ型の後翅を有する昆虫の翅の展開・収納行動をハイスピードカメラ,3次元計測技術を用いて詳細に観察する手法を構築し,ハネカクシ,テントウムシの収納・展開メカニズムの解明に成功した.折紙の幾何学を用いて翅のデザインを弾性力学的観点から説明する新しい折りたたみモデルを提案すると共に,人工の展開翼に応用するための折線パターンの一般化を行った.昆虫の翅は,人工物とは比較にならないほどの高い収納率,展開再現性,信頼性,軽量性を併せ持っている.本研究成果はこれらの優れた特性を工学応用する道を開くものである.

Coelophora inaequalis (Fabricius, 1775) is recorded from several localities on the islands of Okinawa-jima and Ishigaki-jima, Okinawa, Japan for the first time. This species is considered to be currently introduced from overseas and possibly already naturalized in these islands. Several color forms are known in this species, but only two forms, Tortoise-shell and Nine-spotted forms, have been found the populations in Okinawa.

A Japanese male repeatedly infested with <I>Amblyomma testudinarium</I> in Malaysia was reported. He visited to Ulu Gombak, Malay Peninsula, Malaysia on April and May 2007, and he recalled three times of tick bite during traveling. The first tick bite was by one nymph infested on the inner side of the brachium of the patient. After a few days, erythema with a diameter of 2 cm was found at the site of tick attachment. Pain of the site remained for 20 days. The second tick bite was by larvae infested on the skin surface of the abdomen, basal portion of the thigh, and scrotum of the patient. He felt a pain at the moment of tick infestation. The pain remained for 15 days. The third tick bite was by a larva, and the tick was found in the phyma of his back immediately after his return Japan.

In 2000 to 2003, the terrestrial staphylinoid fauna was quantitatively surveyed at nine stations (TK01-TK09) six times a year for each in the garden of the Imperial Palace, Tokyo, Japan. Each staphylinoid sample was extracted by Tullgren funnel from leaf litter and humus of five quadrats each sized 1m×1m. Sixty-two species of four families were recognized, 13 species of them being recorded for the first time from the Imperial Palace. Species diversity and similarity of six communities were analyzed by three diversity indices (Shanon-Weaner function H', Pielou's index of equitability J' and total diversity H'N) and three similarity indices (Jaccard's coefficient of community CC, Nomura-Simpson's coefficient NSC and Pianka's overlap index α). In the comparison of species diversity, TK03 was significantly low in H' and H'N and the other five were not different. In TK01 to TK03 surveyed in 2000-2001, the diversity was high in January to May, in a low level in July, and recovered in September; on the other hand, it decreased more or less in June to October in TK07 to TK09 (2002-2003). As to the similarity of species component, TK07 harbored many species completely covering the faunas of TK01, TK02 and TK03. A significant difference of TK09 in overlap similarity was indicated in an analysis by Pianka's α.
