|Scale Insects (Chloropulvinaria polygonata, Aspidiotus destructor and Rastrococcus sp.)|
In recent years, scale insects (Chloropulvinaria polygonata, Aspidiotus destructor and Rastococcus sp.) become serious pest on mango. The nymphs and adults of pest suck the sap of leaves and other tender parts which result in reduction of vigour of plants. Scale also secrets honeydew which facilitates in development of sooty mould on different plant parts.
Chemical applications should be used only when parasites are not economically effective. The application of pesticides may kill natural enemies of the scale and result in a resurgence of the pest.
