  • In this paper, the author gave a brief review on the meaning and background involving the growth of chemical ecology. Semichemicals which might be developed as insect control techniques incorporating in IPM program were described. The relevant semichemicals were grouped under separate topics including intraspecific semiochemicals, or pheromones (sex pheromones, alarm pheromones, and epidiectic pheromones), and interspecific semiochemicals, or allelochemics (allomones of Plant origin, and kairomones favoring natural enemies). Here, the author dealt with those of practical aspects only. The prospects of chemical ecology in insect pest management were also proposed.

  • A gene's influence on an organism's Darwinian fitness ultimately determines whether it will be lost, maintained or modified by natural selection, yet biologists have few gene expression systems in which to measure whole-organism gene function. In the Department of Molecular Ecology at the Max Planck Institute for Chemical Ecology we are training "molecularly enabled field biologists" to use transformed plants silenced in the expression of environmentally regulated genes and the plant's native habitats as "laboratories." Research done in these natural laboratories will, we hope, increase our understanding of the function of genes at the level of the organism. Examples of the role of threonine deaminase and RNA-directed RNA polymerases illustrate the process.
