| Abstract |
Feeding injury caused by white mango scale insect, Aulacaspis tubercularis (Newstead) reduced leaves chlorophyll content significantly between infested and uninfested leaves. Quantification of chlorophyll loss caused by A. tubercularis feeding on mango leaves is vital importance for photosensitise and later on crop yield. The uninfested leaves had higher levels of chlorophyll in comparison with infested ones. Economic threshold and economic injury levels were determined depended on the loss percentage of total chlorophyll on mango leaves were 40 and 66 insects per leaf, respectively.
