Abstract

B. cereus strains were isolated from three district of North Sulawesi. The B. cereus strains are potentialindigenous bacteria for biological control agent against P. xylostella. The B. cereus strains were isolatedusing Ohba and Aizawa methods. Two hundred and two isolates putatively were isolated and identifiedas member of species B. cereus. Subseguently, representing isolates were selected to be screened forthe ability to kill P. xylostella. The screening test was conducted by using leaf depped methods with theconcentration of 1,22x108 spore/ml. The potential to kill test insect was assessed by mortality value. Theresult indicated that 10 isolates out of 15 of could produce mortality of insect from 50 to 100% afterexposure of 96 hours. It was confirmed that based on symptoms produced as well as bacterialcharacteristics reisolated from cadaver of test insect, the death of the test insects was certainly causedby application of bacterial isolates. It could be concluded that indigenous bacterial isolates identified tobe member of B. cereusare potential for biological control agent against P. xylostella. ABSTRAKUntuk memperoleh bakteri yang berpotensi sebagai agensia pengendali hayati hama Plutela.xylostelladilakukan isolasi dan karakterisasi bakteri indigenous.

Abstract

ABSTRACT Identification using morphological characters has time consuming. Currently, identification using molecular markers has now been popular due to rapid, saving time and more precisely. Superjohn potato variety has been cultivated in North Sulawesi. However, the Superjohn potato variety has not been characterized using molecular markers. This research was aiming to identify “Superjohn” potato based on RAPD (Random Amplified Polymorphic DNA) markers. The research was conducted in field and laboratory. Field research was performed by taking some young leaves from “Superjohn”, Granola, and Atlantic variety from the field. Identification using molecular marker was conducted at laboratory.  Nine RAPD primers were used to identify the superjohn variety. The nine primers were OPA-1, OPA-2, OPA-3, OPA-4, OPA-5, OPA-7, OPA-9,  OPA-10, and  OPO-1.  The molecular identification revealed that “Superjohn” variety was different with Granola and Atlantic. OPA-9700 primer could be used for identification  “Superjohn” variety while OPA-101000 primer was suitable  for identification  Granola variety.
