Systematics and evolution

  "It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change." - Charles Darwin

         Insects are one of the most diverse organisms on earth. Their ancestors likely originated at the same time as terrestrial plants, about 480 million years ago. Study on insect evolution will focus on the process of gradual change during new species being, while study on insect systematics will provide an information to support relationships between modern life form. Multidisciplinary approach such as morphology, molecular genetics, cytogenetics, sexual compatibility, chemoecology, are currently used for distinguishing forms or species. Understand of systematic and evolution among various forms or species will shed light on effective and sustainable pest management.
