They are considered important because they infest the crop during the flowering season.Ĭontrol – Flooding of orchards with water in October kills the eggs and plowing the orchards in November exposes the eggs to the sun’s heat. After climbing up the Mango tree, they start sucking the sap of tender plant parts. They secrete honeydew, a sticky substance, which facilitates the development of the fungus Maliola mangiferae. Excessive and continuous draining of Mango plant sap causes wilting and finally drying of infected tissue. Nymphs and adults suck the plant sap and reduce the vigor of the Mango plant.
Biological control agents such as the predators Mallada boninensis and Chrysopa lacciperda, and preparation of the fungus Beauveria bassiana are very important and useful in controlling this pest. The second spray at the full-length stage of panicles but before full bloom and then, the third spray after the fruits set at the pea-size stage is recommended.
The first spray must be given at the early stage of panicle formation. Control – Three sprays of about 0.15% Carbaryl or 0.04% Monocrotophos or 0.05% Phosphamidon or 0.05% Methyl Parathion are effective in controlling the hoppers.
