Growing the bold-seeded Indian mustard as a trap crop. Releasing the parasitoid Diadegma semiclausum on the 16th and 21st days after planting. The recommended number of parasitoids to release is 3,000 pupae per hectare per release date in a crop cycle of 70 - 80 days. NSKE can be sprayed onto the mustard to control DBM and aphids. A maximum of only three NSKE sprays are required.
Damage is caused by the larvae of the cockchafer beetle.
They also investigated planting a variety of sugar cane which is tolerant to white grub. The biological control was concentrated on the introduction of a parasitoid wasp and entomopathogenic fungi. Trials begun in 1989 showed that within 2 to 3 years a strain of Beauveria brongniartii originating from Madagascar could stabilise populations of white grub below the economic threshold. The result is the development of a most effective combination, a mixture of insecticide and biocide, which combines the shock effect of the pesticide with the slower, but longer lasting effect of mycosis.
