Book excerpt: In 1980, the International Symposium on the Ecology of Bruchids Attacking Legumes (Pulses), organized by Dr. Labeyrie, was held at Tours, France. Since then, there has been tremendous progress in the area of Bruchid and Legume research. At the same time, as we face the problems of world-wide population explosion and food shortage, the importance of legumes as the world's major protein source is rapidly increasing, especial ly in tropical regions. Thus, it seemed appropriate to hold the Second Symposium in order to review the recent progress in the control of Bruchids and in the biology and ecology of Bruchids and legumes. This is an important part of the search for ways to integrate these fields with a common perspective. The Second International Symposium on Bruchids and Legumes (ISBL-II) was held in September 6-9, 1989 at Okayama, Japan under the joint auspices of the Japanese Society of Applied Entomology and Zoology and of the Foundation for Advancement of International Science. Significant contributions have originated in Japan on the study of Bruchid and legumes. Most notably, the study on population ecology by Professor S.

This book was released on 2013-03-09 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: As editor of this volume I am not going to emphasize the economic im portance of the Bruchids of pulses, nor how necessary it is to know the conditions of infestation of crops in order to achieve an efficient protection; both points are testified by F.A.O.'s sponsorship, as well as of the International Organization for Biological Control. On the other hand I would like to stress the scientific interest of the study of 'domestic' bruchids. It raises questions which require that present basic entomological knowledge be extended. I am not going to review all questions raised but I will emphasize those I am most aware of. Some bruchid species have been able to colonize habitats differing totally; some differing in their latitude, and thus their basic periodicities; others differing in their degree of complexity (stocks of seeds): What are the respective roles played by polymorphism and plasticity in that exceptional capacity? What differences are there between the populations living on wild plants in dispersal areas and those living in stocks? What are the alterations brought about by the drastic selection pressures in populations having later colonized habitats ecologically similar to the original habitats? What factors determine the degree of specificity of trophic relationships, and the possibilities of extension of the niche? What influences are exerted by the other elements of the original bio cenoses upon the behavioural evolution of these species? Such are a few fundamental problems that can be tackled directly through

Available in PDF, EPUB and Kindle. Book excerpt: Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.
