Histochemical changes after feeding injury by Bemisia tabaci
In Georgia (US), investigations were conducted to measure the effects of feeding injury induced by larvae and adults of Bemisia tabaci (EPPO A2 quarantine pest) on the chlorophyll content and the gas exchange rate of tomato leaves.
It was found that the feeding activity of the whitefly reduced the net photosynthesis and transpiration of the leaves. Larval injury reduced the leaf chlorophyll content and the phytosynthetic capacity of the remaining chlorophyll. Furthermore, it was detected that larval injury reduced the tomato leaf gas exchange more than adult injury.
