中文摘要：对雷州半岛海域大珠母贝贝壳凿孔贝类进行了调查研究。结果显示:雷州半岛海域大珠母贝贝壳凿孔贝均为小型的双壳类,褶白蚶Acarplicata(Dillwyn)、偏顶蛤Modiolussp.、翘鳞蛤Irusspp.(两种)、单韧穴蛤Vulsella sp.、杯石蛏Lithophaga calyculata(Carpenter)、蝶铰蛤Trigonothracia sp.、短壳肠蛤Botula silicula(Lamarck)、楔形开腹蛤Gastrochaena cuneiformis Spengler等共9种,其中短壳肠蛤(Botula silicula(Lamarck))的出现频率最高,达50%左右,为雷州半岛大珠母贝贝壳凿孔贝类的主要种类;大珠母贝年龄越大,寄生凿孔贝类数量越多;凿孔贝类可以在孔穴中生活较长时间,最长为6a,生长过程中分泌腐蚀性物质腐蚀贝壳,在贝壳内侧形成斑痕,或凿穿贝壳。

外文摘要：Studies on the molluscas boring in the shells of Pinctada maxima （Jameson） liveing in LEIZHOU peninsula waters were undertaken in the paper. Results show that there are nine species of the boring molluscas which are all small bivalves that are .4car plicata （Dillwyn）, Modiolus sp., Irus sp., Vulsella sp., Lithophaga calyculata （Carpenter）, Trigonothracia sp., Botula silicula （Lamarck）, Gastrochaena cuneiformis Spengler, among which the frequency of Botula silicula （Lamarck） is the highest and can reach up to 50%, so it is the main species harmful to Pinctada maxima living in LEIZHOU peninsula waters. The amount of the boring moUuscas is directly related to the age of Pinctada maxima. The older the individual of Pinctada maxima is, the more the amount of the boring molluscas will be living in the shells of Pinctada maxima will be. The boring molluscas always live in the cave for years and along with its growth they can constantly excrete substances that will erode the shells of Pinctada maxima and make the cave larger and deeper, and can eventually bore through the shell or make ＂scabs＂ at the inner surface of the shells of Pinctada maxima, and will have a negative stimulus to the mantle or adductor and a bad effect on the growth of Pinctada maxima.
