项目摘要

In August, 1993, surveys were made in Palawan, and about 100 species of the Coccoidea, 60 species of the Thysanoptera, 40 species of the Tortricidae, and about 100 species of leaf-mining microlepidoptera were collected. In August, 1994, Mindoro and the Bataan Peninsula were selected for surveys, and the collections include about 80 species of the Coccoidea, 40 species of the Thysanoptera, 20 species of the Tortricidae, and about 80 species of leaf-mining microlepidoptera. The collections have all been brought to the laboratories in Japan for study, and first papers based on the collections will be published during 1995.Before the surveys these insect groups had been known only by fragmentary records in the Philippines. A good number of coccoid species were collected from diverse plants ; especially in the family Diaspididae, many new genera and new species have been found in the collection, and some of them are quite peculiar. About 150 species of the family Gracillariidae, all bred from leaf-mines, have been found, and about half of them are new species. The tortricid moths obtained, though limited in the number of species, were mostly bred from larvae, thus their host plants and habits are known ; further, they are mostly new to the Philippines. Wide-spread species form a large proportion of the thrips collected, of which the host plants are also known. Thus, information as to host association, useful not only in taxonomy and evolutionary study but also in pest management, has been accumulated in these economically important microarthropods. The flora and fauna of the Philippines enjoy high rates of endemism. In spite of the limited durations and localities the surveys have been successful in showing that the Philippine fauna of some insect groups including diaspidid scale insects and gracillariid moths are worthy of a large-scale study from the viewpoints of biogeography, taxonomy and evolution.

1993年8月，在巴拉望岛进行了调查，共收集到球科昆虫约100种、囊翅目昆虫60种、蝽科昆虫40种、采叶小鳞翅目昆虫约100种。1994年8月，在民都罗岛和巴丹半岛进行调查，共收集到球蛾科约80种，囊翅目40种，蝽科20种，采叶小鳞翅目约80种。这些收藏品已全部送到日本的实验室进行研究，以这些收藏品为基础的第一批论文将于1995年出版。在调查之前，这些昆虫群只在菲律宾有零星的记录。从多种植物中采集到大量球虫种类；尤其在棘蛛科中，发现了许多新属、新种，其中一些属、新种较为奇特。已经发现了大约150种从叶矿中繁殖出来的细叶虫科，其中大约一半是新种。所获得的蛾类虽然种类有限，但大多是由幼虫繁殖而来，因此它们的寄主植物和习性是已知的；此外，他们大多是新来菲律宾的。在收集到的蓟马中，分布广泛的物种占很大比例，其中的寄主植物也是已知的。因此，在这些具有重要经济意义的小节肢动物中积累了大量的寄主关联信息，这些信息不仅对分类和进化研究有用，而且对害虫防治也有重要意义。菲律宾的动植物具有很高的地方性。尽管调查时间和地点有限，但已成功地表明，从生物地理学、分类学和进化的角度来看，菲律宾的一些昆虫类群，包括散翅蚧虫和细鳞蛾，值得进行大规模的研究。
