Assessment of the pest and disease problems

Nursery and Plantation Insect pests of fast growing native tree species such as Ailanthus excelsa, Melia dubia, Gmelina arborea, Morus alba, Dalbergia sissoo, Thespesia populnea and Bombax spp. in the States of Tamil Nadu and Kerala are being studied and key pests identified. Assessment of pests and diseases problems of Eucalyptus clones at three different locations of Tamil Nadu, Kerala and Andhra Pradesh are being investigated and important pests and diseases categorized. New invasive gall insect pest, Leptocybe invasa Fisher & La Salle on eucalyptus was reported and its biology and management strategies are being worked out. Etiology and Histopathological studies of Blister bark disease with view to understand the mode and spread of the diseases in Casuarina equisetifolia are being carried out.

Development of Integrated pests and diseases management

Integrated Pests Management (IPM) for the key pests of native tree species such as Ailanthus excelsa , Gmelina aroborea and Dalbergia sissoo are being developed.

Biological control of pests and weeds

Methods are being evolved for isolation, purification, characterization and formulation of bioactive compounds from the plants known for pesticidal properties. Currently bioactive principles of different tissues of Acacia nilotica are exploredfor the management of forestry insect pests in terms of antifeedancy, insecticidal and growth disrupting properties.

Biological control

Exploration of potential biocontrol agents (Insect pests and diseases causing pathogens) from India for management of A. nilotica ssp. Indica in Australia is being carried out.

Studies on host plant resistance

Screening of clones/provenances/families and progenies of Eucalyptus, Casuarina, Acacia mangium and Ailanthus excelsa against the key insect pests and diseases is being carried out. Charcterization and evaluation of Allelochemical profiles of the tree species such as teak, cauarina, Ailanthus and Acacia managium in respect of host plant resistance/susceptible for the key pests are being studied.
