Both nymphs and adults suck the sap from the lower leaf surfaces through their piercing and sucking mouthparts.
While sucking the plant sap, they also inject toxic saliva into the plant tissues, which leads to yellowing.
When several insects suck the sap from the same leaf, yellow spots appear on the leaves, followed by crinkling, curling, bronzing, and drying, or “hopper burn”.
Management
Removal of weeds and alternate host plants such as Hibiscus, bhindi, custard apple, guava etc.
