A Biological Control Laboratory has been set up at Rajhana (near New Shimla) in the Shimla district for promoting the use of natural enemies for the control of pests of horticultural crops. The predators/parasites of some of the major pests shall be reared in the laboratory for further release in the field for control of the pests. This will help in decreasing the use of chemicals in pest control and thereby reducing environmental pollution.
Detail of Bio control agents being multiplied/released by the Biological Control Laboratory is given as under:
| S.No | Bio-agent | Effective against the pest |
|---|---|---|
| 1. | Aphytis sp.procila group | Sanjose Scale |
| 2. | Pharocymnus flexibilis | Sanjose Scale |
