Role of Insect Pests in the Mortality of Kikar and Shisham in Punjab

Abstract

In the recent past, large scale mortality of Kikar (Acacia nilotica Willd.) and Shisham (Dalbergia sissoo Roxb.) was observed in Punjab and the adjoining states. These species are grown extensively in various sites in Punjab, on roadsides drain sides, canal sides, etc. Termites were found to be the common enemies of both the trees. Celosterna scabrator grubs were found to be associated with kikar trees throughout Punjab. In addition, Plecoptera reflexa was found associated with shisham and lndarbella quadrinotata was found to cause damage to kikar trees. These insects are discussed in detail in this paper.
