Indian Sawflies Biodiversity (Vol. I: Genus Tenthredo Linnaeus Hymenopterak Symphata: Tehthredinidae) - Hardcover
Inhaltsangabe
Though Holarctic in distribution, genus Tenthredo is mostly confined to the temperate, boreal and arctic regions of the old and new world including many species of the high mountains of South east-Asia. It is the largest genus of Sawflies with more than 1000 described species. The members of this taxon are generally quite robust, sturdy, lusty and showy in appearance. In India they are mostly restricted to the chain of high altitude mountains (800m - 4000m. AMSL) starting from Jammu & Kashmir upto Nagaland. They start emerging during the pre monsoon months (April-May) and remain active for 5-6 months i.e. upto post monsoon months (August-September). Though generally said to be univoltine, in India, (particularly in north eastern states) there are many species which appear to be multivoltine as their adults are available in the field for more than 4-5 months inspite of the fact that the adult life span is 40-50 days at the niost. In their daily life, these sawflies generally exhibit predilection for herbaceous and shruber vegetation where sufficient moisture is a regular feature. Broad and leathery leaves of such plants in addition to providing them a shelter against direct exposure to sun and predators, also act as pads for landing, feeding and hunting. Undoubtedly such plants are not necessarily their larval food plants. All known larval forms are phytophagous

Hardbound. Zustand: As New. New. Contents 1. Introduction. 2. Material and Methods. 3. Genus Tenthredo Linnaeus. 4. Key to the Indian species of Genus Tenthredo L. 5. Species catalogue. Abbreviations. Bibliography. Illustrations. Index to the scientific names. This volume covers the first revisionary work on Indian Tenthredo after Malaise 1945. To the hitherto very scanty and fragmentary informations i.e. only about 70 species and subspecies contributed by various taxonomists from the Indian subcontinent 126 species have been added in the form of new as well as first record from the faunistic limits of India. So this volume deals with 196 species/subspecies (new as well as first record) are contributed by Saini and his co workers during the last 25 years. This contribution is an outcome of an extensive and intensive collection surveys of all high altitude localities situated along the entire Himalayan Belt and the Hills of North Eastern States. By providing detailed identification key elaborate catalogue and good number of illustrations (particularly those dealing with genitalia) this work not only compiles the hitherto scattered information on the taxonomic records of this genus it also lays a very solid and stable foundation for the future Sawfly workers intending to explore different aspects of these insects. The author hopes with this reference work at their disposal the future Sawfly workers of this region will be able to contribute tremendously in this field. 250 pp. Artikel-Nr. 68906
