Field performance of some cultivars of Indian gooseberry (Emblica officinalis Gaertn) against bark eating caterpillar Indarbela quadrinotata (Walker).

摘要

Seven varieties of aonla (Emblica officinalis [Phyllanthus emblica]) namely Krishna, Banarsi, NA-10, NA-7, Chakiya, Kachan and Local were screened against bark eating caterpillar, Indarbela quadrinotata, in Nimar region of Madhya Pradesh, India, during 2001-03. The results showed significantly less number of holes (14.36/plant) were observed in local grown variety followed by Kanchan (15.00/plant). The maximum holes (31.01/plant) were recorded in NA-10 at par with Krishna (29.25/plant), Banarsi (24.03/plant) and NA-7 (23.46/plant). The differences might be due to non-preference for oviposition or shelter to the larvae..
