| Sumario: | The objective of study was to investigate the effectiveness of <em>Beauveria bassiana</em> isolate cultured in half-ripe rice media against third-instar larvae of <em>Plutella xylostella</em>. The research used 10 isolates consisted of 4 isolates that were originnally collected from Pagaralam i.e. PD1 (isolated from <em>P. xylostella</em> cadaver), PD2, PD8, PD9B (from <em>Crysodeixis chalcites</em> cadaver), and 6 isolates from other areas as comparison, i.e. CCW3 (from <em>Crysodeixis chalcites</em> cadaver), BBL (from <em>Hypothenemus hampei</em> cadaver), CH (from<em> Conomorpha cramerella</em> cadaver), CPJW (from <em>H. hampei </em>cadavi), WC (from <em>Nilaparvata lugens</em> cadaver), and WSJT (from<em> Leptocorixa acuta</em> cadaver). The parameters that were measured were mortality of larvae, time of death and behaviour of larvae after application. Result of the test showed that <em>B. bassiana</em> isolated from <em>L. acuta</em> (WSJT isolate) caused the highest mortality i.e. 73.34 %, with the highest spore density 5.6x107 spore ml-1 (in half-rice media) and 3.0x107 spore ml-1 (GYA media). The lowest LT50 was 19.27 hours, and was obtained from the application of PD9B. After application of B. bassiana, the behaviour of larvae was slightly change from a healthy one to less in consuming of food and then die. |
