• 中文摘要： 稻細?（Steneotarsonentus spinki Smiley)除寄生於水稻之葉鞘及穀粒內部吸食水稻汁液與
  取食胚乳外，並能傳播真菌類病原菌，誘發水稻病害，故稻細?應是本省水稻不稔症之主因。
  玆將本研究所獲得之結果，摘要列舉於下：
  1. 水稻栽培相複雜，是臺南縣官田鄉稻細?猖獗之主要因素。
  2. 稻細?可藉風力傳播。
  3. 未發現有效之防治藥劑。
  4. 稻細?是本省二期作水稻減產之重要原因之一。
  5. 土壤及灌溉水中未發現稻細?。
  6. 蜜蜂、黑尾葉蟬、褐飛蝨等之蟲體上未發現稻細?。
  7. 再生稻及稻樁，是水稻收割後稻細?主耍寄生場所。
  8. 至目前為止，除牛筋草外尚未發現其它寄主。

• 英文摘要： A large amount of tarsonemids (Steneotar-sonemus spinki Smiley) were found in the in-ternal surface of leaves and husks of rice duringthe second crop in southern Taiwan. Besidesfeeding on rice plant juice, tarsonemids alsoserve as a vector of sheath rot disease (Acrocy-lindrium oryzae Sawada) and other fungus di-seases. Statistically, Steneotarsonemus spinki issupposed to be one of most important factorswhich causes sterility and partial fertility inrice. The tarsonemid outbreak might be attributedto a very sophisticated rice flora. The mites might be spread by the wind. Chemicals seem ineffective in controllingthis mite. There were no soil-borne or water-bornetransfer of tarsonemids. No tarsonemid was found as a phoresy onbees. The stubbles and ratoon rices were consi-dered as a major host after the rice was har-vested.
