Part of the NATO ASI Series book series (NSSA, volume 276)


Injury to various plant tissues by ovipositing Terebrantian species and feeding injuries by thrips species to pollen, flowers, fruit and leaves are characterized for different economic plants. Both the range of damage to individual economic crops and differences arising through attacks on the same plant at different stages of development are included. The range of species attacking the same plant in different parts of the world and how differences in pest status of individual thrips species on a single crop vary from one geographical area to another are presented.
