Plant insect relationships
Plantinsect interactions: an evolutionary arms race between two distinct defense mechanisms. This review foccuses on several aspects of this complex interaction between plants and insects, including chemicalderived substances, proteinderived molecules and volatile compounds of plants whereas metabolization, sequestration or avoidance are in turn employed by the insects. Key words:Take a journey with Conrad, chasing fossils back to the time when insect and plant relationships first evolved. Follow a trail of evidence to find out which insects were eating plants in the coal swamps of the Carboniferous, 300 million years ago. Figure out how species have changed, while types of relationships have persisted. plant insect relationships
Host plant selection is mainly a behavioral process which is governed primarily by chemoreception. Therefore, the emergence of specific insecthost plant relationships most likely results from evolutionary changes in the insects' chemosensory systems. Adaptation to the nutritional quality of the new host plant is a secondary process.

Not only are some insects useful in keeping other pests at bay, they also provide one of the most important services in the plant world. Many insects act as pollinators, transferring pollen from plant to plant as they forage for nectar. In addition to the familiar bees, beetles, flies, moths, and butterflies are also important pollinators.
