Abstract

ABSTRACT   The research aimed to explore potential entomopathogenic bacteria as biological control agent for insect pest of P. xylostella and Spodoptera sp. in cabbage and broccoli. The indigenous bacteria were explored by taking 103 samples from location around North Sulawesi. Bacteria were selectively isolated by using Ohba and Aizawa method and then identified based on morphology. Subsequently the isolates were screened by their potency to kill test insect of P. xylostella and Spodoptera sp. The isolates were able to kill ≥ 50 % test insect considered  as potential for biological control. The potential isolates were then selected and would be developed  as powder and liquid bio-pesticide through large scale production. The result of the study showed that 145 Bacillus thuringiensis isolates and 202 Bacillus cereus isolates were obtained from 103 samples. The screening of the isolates based on standard test insect for cabbage and broccoli were in progress. The potential isolates would be further selected on the basis of their pathogenicity test. Based on pathogenecity test, chosen isolates will be developed as  bio-pasticide to control insect pest of cabbage and broccoli. Keywords : Exploration, entomopathogenic bacteria, biological control, Plutella xylostella, Spodoptera Sp.

Abstract

ABSTRACT Leptocorisa oratorius is one major pest of rice in North Sulawesi. Hence, it is necessary to control the pest. The research objective was to identify and to test pathogenicity of local  entomopathogen fungi which infected  Leptocorisa oratorius. The pathogens were collected through sampling of L. oratorius which had been infected by the fungi in the field. The pathogenic fungi was isolated using PDA medium, identified followed by inoculation for pathogenecity test.  During several sampling pest, it was found that  L. oratorius was attacked by fungal pathogens in the field. The identification revelead that the fungal pathogens were Beauveria sp and Fusarium sp. Both the fungal pathogen produced white mycelium and could only be distinguished using microscope in the laboratory. Result of pathogenicity tests showed that the two fungal pathogens caused different mortality of the L. oratorius. Mortality of  L. oratorius caused by pathogenic fungus Beauveria sp was  30.3% . Whereas, mortality of  L. oratorius caused by Fusarium sp was only 3.33%. Keywords : pathogenic fungi, entomopathogen, pathogenicity tests, L. oratorius
