Abstract
Entomopathogenic fungus Beauveria bassiana is soil inhabited fungus that known to
have a wide range of hosts. Previous work showed that this fungus can be cultured in
solid media using rice bran. The objective of this research was to study the effectivity of
B. bassiana cultured in rice bran to control Lepidiota sp. in semi field experiment. Two
grubs were inoculated into seven-weeks old soybean planted in a polybag. The fungus
was applied one week after grub inoculation, in three levels of dose, i.e. 1 g cultured
fungus/100 g soil; 1.5 g cultured fungus/100 g soil; 2 g cultured fungus/100 g soil, and
control with no fungal application. The applications of the fungus were conducted with
two methods, first, the solid cultured fungus was applied directly into soil around root
area, and second, the solid cultured fungus was diluted into 400 mL water and the fungal
solution was poured on the soil. The results showed that the mortality of treated grubs
was not significantly different from those untreated grubs. However, the weight of fresh
root, fresh plant and dry plant of plant treated directly with 1.5 g cultured fungus/100 g
soil was significantly higher than those of other treated plants and untreated plant. The
direct application of 1.5 g cultured fungus/100 g soil resulted in higher number of seed
per plant than other applications. In conclusion, this fungus can be used to control
Lepidiota sp., although higher dose may be needed.
Key words: Effectivity, Entomopathogenic Fungus, Beauveria bassiana, White Grub,
