The characteristics of indigenous entomopathogenic fungi isolated from insect pests of oil palm

Author(s): SITI RAMLAH Ahmad Ali*; RAMLEE Moslim* ; MOHD BASRI Wahid*

Various entomogenous fungi imperfecti (Deuteromycotina) were isolated from diseased bagworms collected from several sites. Beauveria bassiana was very often isolated from Metisa plana sampled at Bukit Cloh Estate, Kapar, Selangor. It was identified as one of the most important factors in controlling the worst ever bag-worm outbreak occuring in 1991 on the estate. Paecilomyces farinosus and Aspergillus flavus together were responsible for drastic and complete mortality of Mahasena corbetti bagworm reared in PORIM outdoor and indoor insectaries in 1991. On the other hand, A. candidus is commonly associated with M. plana in indoor insectaries, and can possibly contribute to the moderately high mortality. It has been proved to be a potential agent for the control of the insect pest. A. ochraceus and A. flavicep were not often found attacking the bagworms, but the study of their pathogenicity should not be neglected. The macroscopic and microscopic characteristics, morphological dimensions and importance of these entomopathogens are described.
