This book was released on 2012-12-06 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mosquitoes and black flies are a constant threat to health and comfort, yet the modern chemical pesticides used to control them have cre ated serious ecological problems. Populations of resistant mosquitoes and black flies have evolved, beneficial insects and natural predators have been destroyed, and environmental pollution has increased worldwide. Therefore, scientists have energetically sought new, environmentally safe technologies to combat mosquitoes and black flies and the diseases they carry. Among the most effective alternative means of controlling these pests are the highly spe cific microbial agents derived from Bacillus tburingiensis or Bacillus spbaericus. The microbial control of mosquitoes and black flies is a very important, rapidly developing area of science. Entomologists and microbiologists have already achieved spectacular successes using B. tburingiensis and B. spbaericus against these pests. Recent discoveries of new bacterial isolates specific to new hosts and recent genetic improvements in these isolates have created the potential for wide-scale use of these biological control agents. Efficient microbial control of mosquitoes and black flies can now be achieved, but a proper knowledge of factors relating to the safe and effective use of these biological control agents is necessary. The efficacy of B. tburingiensis and B. spbaericus is influenced by the inherent differential tol erance of the target mosquitoes or black flies, by the formulation technology and application of these agents, and by environmental factors, especially sun light and temperature.

Download or read book Ecology and Biogeography in Sri Lanka written by C.H. Fernando and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the late Professor Joachim Illies suggested in 1980 that I edit a volume of the Monographiae Biologicae on Sri Lanka, I was glad to accept the challenge. Although I had spent only six years of my research and teaching career in Sri Lanka, I had made personal contact or corresponded with many scientists who had worked in, still work in, or who have studied material from Sri Lanka. The present domicile of the authors of the chapters in this volume shows the wide geographic spread of interest in Sri Lanka, and indicates also the dispersion of Sri Lankan scientists like myself. Sri Lanka has had a relatively long history of indigenous scientific research in the natural sciences. From the early work of Kelaart (1852, Prodromous Fauna Zeylanicae, Ceylon Govt. Press, 250 pp.) to the present time, there has been a more or less sustained research effort in the natural sciences. The Colombo Museum, which celebrated its centenary only a few years ago, and the world famous Peradeniya Botanical Gardens, served as repositories and bases for continued research on the fauna and flora. There are a number of land marks in these studies.
