Cashew (Anacardium occidentale)

Pest usually appears with the emergence of new flushes and panicle.
Drying of inflorescence and dieback of shoots are the symptoms.
Typical feeding damage symptom is the formation of necrotic lesion around the point of infestation.
The lesions on shoots and panicles coalesce and ultimately result in shoot blight or blossom blight

Spray Pongamia oil (2 ml/litre of water) or Beaveria bassiana (20 gram/litre of water)
Remove the volunteer neem plants in and around cashew plantation.
The eggs of the mosquito bug are naturally parasitized by Telenomus spp. and Erythmelus helopeltidis.
Spiders such as Oxyopes schireta and Hyllus spp. are efficient predators of mosquito bug.
Red ant Oecophylla smaragdina should be encouraged in cashew plantation as it will repel the pest.
