The insect’s world is filled with many odors. Insects use these odors to cue them in a variety of complex social behaviors, including courtship, mating, and egg laying. Scientists and pest control specialists have known about these complex communication systems for decades. The main aim of this study was to visualize the availability, trends and differences in the sources of pheromone control in agricultural growth of Bangladesh. It also concerned on constrains and present use of pheromone and their possible recommendation on behalf of Bangladesh agriculture. It concentrated on the data during last three decades (1980-2010), comprising status of pheromone use in Bangladesh agriculture and its future. Review revealed that Bangladesh has been enormously successful in increasing pheromone use in agricultural production (especially for vegetables). Understanding of the nature of pheromones and their potential for pest control along with the future prospective of pheromone technique in agriculture were stated. Since the pheromone, technologies for control of major crop pests in Bangladesh are still limited. So that this review emphasized on more attention to the authority to increase the research works and project facilities related to develop and promote pheromone techniques. It is highly recommended to increase availability of pheromone in market, more investment in research and development, introduction of newly identified pheromone for specific pest, to assist government and nongovernment organizations to work with farmers to reduce harmful insecticide use and promote pheromone tactics as one part of integrated crop management (ICM).

The application of FRP materials in civil engineering is now a hot spot in the research and development of the international civil engineering field. To conclude on the basis of previous experience, this paper summarizes and reviews current state about the research and use of FRP, while the prospect of using outlook FRP reinforcement to promote the construction in civil engineering application is also given.


When the objectives and the parameters of JET were defined about ten years ago, the existing knowledge of plasma behaviour in tokamaks showed the advantages of the axial symmetry of magnetic configuration, as well as the leading role of the plasma current in heat confinement. After two years of operation, JET has proved to be the world’s most successful device in thermonuclear fusion research. Whereas achievement of the final aim (i.e. the confinement of plasma with temperature and density such that thermonuclear power dominates the heat losses) has never been nearer, results show that plasma behaviour is even more complex than initially anticipated and nonlinear physics, leading to turbulence or chaos, is involved. How this is likely to modify the JET programme is addressed, as well as the prospects for a future reactor.
