Abstract

Stem borers of Indian sandalwood (Santalum album Linn.) in Karnataka, India.

Abstract

The heartwood borer Aristobia octofasciculata Aurivillius and red stem borer Zeuzera coffeae Nietner were found more prevalent infesting sandalwood in natural forest areas of Karnataka. In the sandalwood plantations, Z. coffeae was the major stem borer distributed in all the districts of Karnataka while the infestation of stem borer Purpuricenus sanguinolentus was prevalent in Bangalore rural district. In addition, two cerambycid beetles, viz. Ceresium gracile (Perroud) and Stenodryas nigromaculatus (Gardner), were found infesting sandalwood for the first time. The host plant of C. gracile is so far unknown and S. nigromaculatus is so far reported on Albizzia procera from India. The impact of infestation of these stem borers on the economy of cultivation of Indian sandalwood is discussed.
