The authors conducted field surveys to elucidate the factors at 11 locations in central Kagawa Prefecture, Shikoku Island, Japan. Sap‐exuding trees were found in thirty‐five of 764 Q. acutissima trees, five of 462 Q. variabilis trees, one of 371 Q. serrata trees and none of 3 Q. aliena trees. Wine‐colored cossid larvae and/or their galleries were found on ca. 94% of sapexuding trees examined. All ten adults (two males and eight females) emerged from a part of the cossid larvae were oriental carpenter moths, Cossus jezoensis (Matsumura). The sap‐exudation period was between midMay and early November. Each of the larvae of C. jezoensis making their own galleries on the edge of bark‐abraded parts (sapexuding parts) was occasionally observed biting the surface of the bark‐abraded part by changing the biting spot one after another (scraping behavior), pausing at the entrance of the gallery, fighting with the other inhabiting adjacent gallery, and walking on the stem surface. Furthermore, five larvae were observed attempting to prey on exuded sapfeeding insects. In another survey, the larvae were observed attempting to prey on exuded sap‐feeding insects. One succeeded in preying on an ant, and another on a fly, in addition to preying on algophagid new mite species, Hericia sanukiensis inhabiting in exuded sap flows. Such predatory behaviors observed between June and November roughly coincided with the total period of sap‐exudation. The scraping behavior and the exuded sap flowing from around the entrance of the larval galleries indicate that the long‐term exudation of sap flow from deciduous Quercus trees is actively generated by the larvae of C. jezoensis to propagate the mites and to lure exuded sap‐feeding insects.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"落葉性コナラ属植物樹幹の剝皮箇所から長期間に亘って滲出する樹液の滲出要因を明らかにするため、香川大学農学部（34°16′35″N、134°7′29″E）から15km以内に位置する11地点の雑木林で胸高直径5cm以上の落葉性コナラ属植物を調査した。7〜9月の調査で4樹種が確認され、それらの中でクヌギ Quercus acutissima 764本中の35本、アベマキ Q. variabilis 462本中の5本、コナラQ. serrata 371本中の1本 およびナラガシワ Q. aliena 3本中の0本で樹液滲出が確認された。少数のナラガシワを除く3樹種で樹液滲出木の調査を進めた結果、樹液滲出木中、調査可能な樹高2m以下に樹液滲出箇所（剝皮箇所）のあった35本（クヌギ29本、アベマキ5本、コナラ1本）中の26本でボクトウガ科の幼虫とその孔道が、7本で孔道のみが発見された。このため、その他3地点も含めて3樹種の樹液滲出箇所でこの幼虫を採集し、羽化成虫の分類学的調査を行なった結果、10個体（雄2個体、雌8個体）すべてが四国未記録種のボクトウガCossus jezoensis （Matsumura）であることを確認した。上記35本中の11本（クヌギ10本、アベマキ1本）で、樹液滲出箇所数の時期的変化およびボクトウガ幼虫の行動を2年間（1999、2000年）、4月から12月まで月2、3回の間隔で日中に調査した。その結果、樹液は概略5月中旬から11月上旬まで滲出することがわかった。また、剝皮箇所周縁部に孔道を作ったボクトウガ幼虫は、孔道開口部から体の一部を出して静止していたり、隣接孔道内に生息する幼虫と発音を伴う闘争をしたり、孔道から外へ出て樹幹表面を歩行したりすることに加えて、孔道開口部から体の一部を出して場所を少しずつ変えながら剝皮箇所の表面を削るようにかじること（切削行動）が明らかになった。さらに、樹液が滲出する孔道開口部周辺に集まってきた樹液食昆虫を大顎で捕獲して孔道内に引き込もうとする行動も観察された。このようなボクトウガ幼虫の行動をさらに多く観察するために別の随時調査（1998〜2002年）も行なった結果、樹液中で発生して増殖する日本未記録の Algophagidae 科の新種クヌギジュエキダニ Hericia sanukiensis Fashing and Okabe を捕食するとともに、上記の通り、孔道開口部に集まってきた樹液食昆虫の捕食行動も示し、それらの中のわずか2例であったが、アリとハエを捕食した。6月から11月に亘って観察されたボクトウガ幼虫の捕食行動は上記の樹液滲出期間とほぼ一致していた。このような一致とボクトウガ幼虫が示す切削行動および樹液がボクトウガ幼虫の孔道とその周辺から流下していることを考え合せると、落葉性コナラ属植物の長期間に亘る樹液滲出は、ボクトウガ幼虫が、捕食するためのクヌギジュエキダニを増殖させるとともに、樹液食昆虫をおびき寄せるために、能動的に滲出させているものと考えられる。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"応用生物科学科","subitem_heading_headline":"生物資源生産学大講座","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Department
