Rani, B.J., & Sridhar, V. 2005 Record of arthropod pests on Kalmegh, Andrographis paniculata - an important medicinal plant.. Insect Environment 11(2): 89-91.

Notes: A field study was undertaken during 2001-02 in Bangalore, Karnataka, India to record various pests and their seasonal incidence on kalmegh, A. paniculata. Seedlings were raised in June and transplanted in July at a spacing of 60x30 cm in 20 beds of 2x2 m SUP 2 size. Observations on pest incidence and plant parts attacked were recorded from 5 randomly selected beds (5 plants per bed) at 15 days interval. Brown scale, Parasaissetia nigra, was found to be causing significant damage, as the affected plants exhibited stunted growth and drying, followed by semilooper, Panilla sp. nr. albopunctata, which damaged the plants by feeding on young leaves, flower buds and tender pods resulting in foliage loss. This is thought to be the first record of arthropod pests on kalmegh from India.
