The pathogenicity of -Metarhizium anisopliae var. major - solid substrate (M-SS) was evaluated against Oryctes rhinoceros in a greenhouse and large-scale field study of new oil palm replanting areas. The M-SS was prepared byfermenting 500 g maize branwith 7mlM. anisopliae mycelia liquidfor 30 days to achieve M-SS viability of 91.45 per cent. The greenhouse study indicated that application of M-SS at 3.74 g per sq.m killed 92.17 per cent of the first, second and third instars larvae at six weeks after application (WAA) and is equally effective as commercially prepared Metarhiziumformulated in powderform. Then, performance ofM-SS in the field was tested in two replanting plots (28 ha and 33 ha) through a blanket application and artificial breeding sites (ABS) technique (50 ha), integrated with pheromone trap, which was manually applied on decomposing chipped oil palm biomass aged four to five months after felling and chipping (MAF). The result of these studies showed that 32.9-42.6per cent ofO. rhinoceros were infected especially on third and second instar larval at twenty-fourth and fourteenth month after application (MAA), respectively. These results indicate that M. anisopliae applied in the form of solid substrate was effective in controlling O. rhinoceros population which would subsequently prevent the pest outbreaks in the oil palm -to- oil palm replanting areas. The M-SSform is easily prepared and very practicalfor use by the planters to control the target pest.
