Abstract

Santalum album Linn. (Santaniaceae), distributed all over India, is a tree of great economic importance because of its fragrant heartwood and oil. Surveys were conducted during 2000- 2005 in the sandalwood bearing areas in Karnataka to study thc occurrence of sucking pcsts of sandalwood plants in the nurseries, plantations and natural forests. Insccts belonging to Coccoidca (Hemiptera) were the most predominant among the sucking pests. The diversity of hymenopteran parasitoids was very high on most of the pests. Many of the parasitoids belonged to Encyrtidae followcd hy Aphelinidae. Eulophidae, Pteromalidae and Braconidae. Seasonal dynamics of Cardiococcus bivalvata (Green) and its four important parasitoids Was studied in 2002-2003 to evaluate their role in pest Suppression. A list of the coccoid pests on sandal along with their natural enemies including parasitoids lind predators is given in the paper.
