Author(s): Haresh Kumar, Shashank Sharma

Abstract: Aonidiella orientalis is a worldwide pest of fruits, commercial and ornamental plantsand removes phloem sap, resulted in the reduction of chlorophyll content. Quantification of Chlorophyll and Carotenoid loss caused by the above insect feeding on Dalbergia sissoo is of vital importance. The chlorophyll and carotenoid contents of uninfested and infested leaves of guava by using 118-spectrophotometer was found to be reduced by 31 and 35% respectively.
