Teak predators destroyed by virus from their own larvae. Validated RNRRS Output.


This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Summary for Project title: R6295: Use of Baculovirus control agents within an integrated pest management strategy against teak defoliator, Hyblaea puera, in India.

A simple, effective and environmentally benign method of reducing teak defoliator moth numbers has been tested successfully in Kerala, India. Attacks by the moth dramatically strip the leaves from these valuable trees, causing poor growth and yield loss, distortion of the wood and loss of income for teak farmers. The new method prevents defoliation, minimizes tree damage and increases growth, productivity and employment opportunities. The system uses a baculovirus, obtained from moth larvae and harmless to humans and other insects, sprayed directly on the moths when they appear on the trees, their arrival monitored by forest workers. A pilot virus production plant is already supplying both commercial and government teak plantations in Kerala and neighbouring states. When fully adopted, the strategy will provide jobs for local people as monitors, larvae collectors, and virus sprayers.
