Pests of Anola_Identification_IPM_Dr.UPR.pdf

Amla (Indian gooseberry) trees can be affected by several pests that can impact their growth and fruit quality. Here are some common pests associated with amla:

Aphids: These sap-sucking insects can cause leaf curling, yellowing, and stunted growth. They may also transmit viral diseases.

Mealybugs: Mealybugs feed on the sap and can lead to leaf yellowing and sooty mold due to their honeydew excretion.

Scale Insects: Scale pests attach to branches and leaves, sucking sap and weakening the plant over time.

Spider Mites (Tetranychus spp.): These tiny pests can cause stippling on leaves and may lead to significant leaf drop in heavy infestations.

Fruit Flies: Certain species lay eggs in the fruit, leading to larvae feeding on the flesh, which can cause rot.
